Different Forms of Solar Power For Kiwis

Over the years, experts have established different technologies that help convert sun rays into energy. Photovoltaic technology helps convert sunlight into electricity, while solar thermal heat helps in harnessing the heat. These technologies are standard in New Zealand and across the globe.

Solar energy is widely available to meet your needs. However, the main challenge involves collecting a share of radiant heat and converting it into electricity. Here are the various types of solar power that serve as a viable solution.

1. Photovoltaic Solar power (PV solar)


PV solar power technology helps in converting sunlight directly to electricity. This process uses panels made of semiconductor cells that get the job done. These solar power plants cover large areas; therefore, they can be fed into power grids.

This solar power works by following the electric current occurs in cases where the electrons are displayed principle. Moreover, the photons exited the other atoms of the specific semiconductor element. This panel is made of several cells converting light into current.

Photovoltaic solar powers are reliable and valid for large and small areas.

2. Thermal solar power

Thermal solar power generation systems collect and concentrate sunlight to generate electricity. They are designed. It increases the high temperatures needed for making power. These power systems have reflectors to capture sunlight and focus it on the receiver.

Thermal solar power has tracking systems that allow them to concentrate on focusing the sunlight on the receiver. The feature is essential since the tracker helps reflect the sum to the receiver even as the sun changes positions. They also have advanced technology that increases solar heating.

This solar power has a parabolic trough collector technology important in increasing the rate at which the sunlight is converted into electricity. Moreover, they are designed to last for a long time giving you long term service. After purchase, you will live for long time-saving money that would be used to pay bills.

3. Off grid solar power and ongrid solar power

The ongrid solar power system uses standard inverters connected to the public electricity grid. The excess solar power heat is transferred to the electricity grid. In case your area has a blackout, you cannot generate electricity for safety reasons.

When the solar system stops operating, you will start consuming electricity directly from the public grid.

The off-grid system, on the other hand, is not connected to any electricity grid. For this reason, it requires a battery to aid with the storage. This system is becoming outdated with time; however, it plays an essential role in ensuring cells have enough energy even during winter.

The off-grid solar panels cost $2.96 per watt while the on the grid is much cheaper.

Five hours of light in NZ are enough to charge the batteries or ensure that the on grid solar power operates effectively. These solar panels play an important role in saving thousands, which could otherwise be used for electricity bills.

Bottom Line

Sunlight can easily be converted into electricity using solar panels. They are designed in different ways to help meet your needs. These NZ solar power systems offer potential energy savings for you and are available at low prices.


Electric Solar Panels around the world

The human race needs energy. We need energy to power our cars, power plants, water systems, cook our food, and basically to do anything in our daily lives. Energy has always been around. In fact, our ancestors have used fire to cook their food and to ward off unwanted animals.

In the earlier industrial revolution, energy has been used to run power plants and machines that help society function more efficiently. This practice has continued today, as well. Efficiency continues to rise rapidly as we continue to use energy, replacing or further improving the many ways we do our work.

Modern Day Energy Use

In modern society, it is no longer a question that we need so much energy to power the many things we have today. From the small scale energy use in our houses, to the power plants that power companies big and small.

Although we have moved on from using the nomadic types of energy, we continue to use energy that harms our environment. Fossil fuels have been used in our society, powering our cars, and our day-to-day needs. It has been over a century and burning fossil fuels continue to generate the most energy required to power everything.

Oil, coal, and gas make up 80 percent of our needs in terms of energy. This comes at a great cost for us and for our environment – gravely polluting our seas, lands, and air. If we were to continue with the scale we have today, we will surely perish.

The Solution? Alternative Energy!

With this problem comes a solution, and that is the use of alternative energy. This type of energy does not require the use of any oasis fuels. Instead, alternative energy makes use of wind, geothermal, hydroelectric, tidal, biomass, hydrogen, and solar power.

Solar Power

One of the most common and arguably the easiest way to help the environment and to cut costs on energy use is through solar power. Coming from the word solar, this uses the light energy emitted from the sun as energy, therefore powering our homes and establishments.

How Solar Power Works

Essentially, a solar panel works by allowing particles of light to knock on electrons free from atoms, inducing electricity flow. A solar panel is made of many small units called photovoltaic cells (meaning they convert sunlight into electricity). Linking these cells up makes a solar panel.

That is not the only important part of a solar panel. A solar panel is also comprised of an inverter – used to transform DC (Direct Current) into AC (Alternating Current). This, in turn, is used in grids needed to be able to feed electricity into national grids.

Why Use Solar Panels?

Having a solar panel (system) significantly decreases your spending on electricity. In New Zealand, prices of such have fallen dramatically, making them much more accessible to the many people who want cheaper electricity. When connected to the grid, solar power systems cost less than a quarter of the prices before. A standard 3kW system that used to amount to a total of $40,000 back in 2008, now only cost $8,500.

Don’t Fall for False Advertising When It Comes to Electric Solar

If something you see or read is too good to be true, then it may be so.  There are many companies offering enticing promos and discounts to consumers that a lot of us got caught by the tempting offer not knowing it is just what it is, something that will catch your attention and that ends with that. Nowadays, we all must not believe everything that we see or read.  Consumers must learn to look at the bottom of the story, question ourselves – what’s the catch?

New Zealand’s Solar Energy Industry

The solar energy industry in New Zealand has been on the rise these past few years.  A large percentage of electricity in the area has come from renewable energy and this includes power generated from the sun aptly called as solar energy.  In the mid-2010, solar technology in New Zealand has become affordable compared to earlier years.  This type of energy source is seeing albeit a slow but steady increase in both the residential and commercial market.  The price of getting this type of energy though is one of the primary concerns that may impact its sustainability. 

Advantages and Disadvantage of Using Solar Energy

There are several advantages and disadvantages in using solar energy, what matters though is what are your needs and wants and if using this type of energy answers to them. 


  • Renewable Energy Source – This type of energy source can be harnessed in all corners of the globe and is readily available every day. The sun will not run out unlike some energy source.
  • Reduces Electricity Bills – Because the energy needs are addressed by the solar power system, the electricity bill will definitely be lowered.
  • Diverse Application – Solar energy is not just an alternative source for electricity, it has many uses as well. One of these is used to heat water both for residential and commercial areas. In some areas, it is used to distill water and even power up satellites in space.
  • Low Maintenance CostsSolar energy systems (e.g Christchurch) need only to be cleaned therefore it has low maintenance cost plus it needs to be cleaned at least from a couple to several times per year only. There are cleaning companies specializing in solar energy systems and there are some systems that come with a warranty.
  • Technology Development – With the advancing technology, there will always be future developments in this industry. In the future, this energy power will be offered at lower cost and can harness more energy.


  • Cost – The initial cost of setting up a solar energy system can be high because you have to pay for the panels, inverter, batteries, wiring and installation. But with the developments made in this industry, prices may be lowered in the future.
  • Weather Dependent – Energy can still be collected even during cloudy or rainy days but of course, it is to be expected that efficiency can be affected.
  • Solar Energy Storage can be Expensive – With solar energy, it has to be used right away so if you are planning to use it during the night, one would need storage for the power collected. Batteries to store solar power can be quite costly but you would need it if you want to collect solar energy during the day for you to be able to use it at nighttime.
  • It Needs Lots of Space – The more electricity consumption you have the more solar panels are needed. If you are expecting a high consumption of electricity, you would need to make sure you have enough space in your roof where solar panels can be placed. If this is not enough, you would need to put in the backyard but it must be a place where it can get a lot of sunlight.

Common Mistakes when planning to use Solar Electricity Systems

As much as we all want to lower our electricity bills, there is always a hesitation when it comes to change. Changing the energy source used in a home can be quite daunting and aside from that, everybody hesitate because of the cost.  Putting off from the use of this type of energy may not immediately yield unfavorable result but the longer this is put off the more is spent in paying electricity bills.

Another thing that one should look into is not getting multiple quotes.  At the first opportunity that an installer will present the quote, you would tend to grab it immediately not knowing that there are other service providers offering more value for your money.  It is always advisable to check the competitors.

Another misconception is that the cheaper, the better. You would think that being able to grab the best deals for a solar panel; you may have hit the jackpot not knowing that in the long run this might get back at you. Using low quality panels means that they may have shorter life span or the quality may not be that great therefore needing fixings or even replacement earlier than anticipated.

Although, it does not say, but the most expensive thing in the market but it is always advisable to check the quality first and then add on to that the cost incurred.  Some people may also think that they can do the installation themselves just by reading the instructions but knowing the value a properly installed solar system can give, it is always best to refer these things to the professionals.

Getting Hooked on False Advertising

There are solar installation companies offering cheap prices for solar installation. Of course, with cost being one of the primary concerns of consumers they will definitely take into consideration anything that may save them some money.  With these offers, they are lured to grab the opportunity to avail of cheap installation cost not knowing that they may have cut on the cost but they must have cut on the quality as well.

Things may not immediately go down south but later on, problems may arise and you will be trapped in a binding contract where the installation company will not be held liable for any future problem.  You may end up spending more instead.

Quality of service may be okay but the quality of products used may be the one sacrificed to cut on the cost. Therefore it is always important to check every corner and weigh your options properly. This is a big decision to make therefore a little more time might be able to benefit you in the long run.

Solar Heating made easy!

Solar heating is quickly gaining popularity as a choice for homeowners and businesses alike. Not only is it the cheaper option in the long term, it’s also environment-friendly. You also lessen your carbon footprint by using solar power and solar heating. More and more people are now using solar heating and solar panels.

What Is Solar Heating?

Solar heating is the renewable energy system that absorbs the sun’s energy in heat form instead of using it to generate electricity. Passive solar heating systems don’t have any mechanical parts. Solar power also allows for solar water heating.

What Is Solar Water Heating?

Solar water heating converts sunlight into heat for water heating with the aid of a solar thermal collector. There’s a vast array of configuration with different costing geared towards offering solutions for various climates and latitudes. Solar water heaters are mostly used for residential and a few industrial applications.

How Solar Heating Works

Solar collectors have direct systems that circulate water where the sun heats it up using the sun’s thermal energy. The fluid then goes through a heat exchanger in the storage tank, shifting heat to the water. The non-freezing fluid then goes back to the collectors.

What Is Sustainable Energy?

Sustainable energy refers to humans using energy that “meets the needs of the present without compromising the ability of future generations to meet their own needs.” There are two pillars of sustainable energy strategies: energy conservation and cleaner methods of producing energy.

Sustainable energy is a wonderful solution for both existing and new homes. You can easily have solar panels installed on your roof. While building a new home, you should install solar panels right now as it will likely increase in cost in the near future. You should make provisions for solar power such as using a solar-ready water cylinder or put pipe work and wiring in place.

What Are Photovoltaic Solar Panels?

Photovoltaic solar panels harness the sun’s energy to generate enough sustainable electrical energy to power your business or home. To offset your energy bill, you can use the grid connected system, which allows the energy generated to be fed back into the national grid. Or you can use off the grid system and be totally independent of the grid by storing energy in batteries. Wind turbines or Micro Hydro generation are other alternatives that may be viable on your site.

Esolar.co.nz can design and install an off the grid or grid connected solar panel system to meet your energy requirements and budget. By utilising either photovoltaic solar panels, wind turbines, or mini hydro generation you will no longer be suseptable to the every increasing power prices, while at the same time reducing your environmental impact. Other services provided include consultancy, energy assessments, design, and installation of remote energy systems and much more.

Solar Heating: Installing Solar Water Heating Makes Sense

You can use solar water heating panels to heat your water or swimming pool. The exact amount you will save solar heating your water will vary but it won’t be too long before your new solar system will have paid for itself.

It’s been estimated that for an average household, solar water heating from solar panels will provide 75 percent of your annual hot water needs. Systems can be designed to heat pool and swimming pool or we have specific solar pool heating systems available.

Solar Electric Technology is one of New Zealand’s leading solar companies. Our technicians have installed over 1,000 solar power, solar hot water, wind and mini-hydro systems throughout New Zealand and Australia.

Here are some of our more recent jobs:


This is a 12kWp grid tie solar system we have installed in Motueka. The site is 3 ph, with 2 houses and a swimming pool, which will run off of the solar system. The system is spread over multiple roofs and the solar panels face east, north and west so that they achieve a long solar generation day.

We have used Enphase micro inverters, which allow us to face the solar panels in various directions. They also allow us to monitor each individual panel to see how it is performing.


This is a recent job we completed in Picton. We are using a high quality Austrian made Fronius string inverter, to manage the energy from the Jinko solar panels on the roof. An Elios Power Reducer will also divert any excess solar energy, not being utilised in the house, into the hot water cylinder. The more energy consumed on site, the better the return on investment.


This is an installation in Blenheim with a dark roof and so we have used our all black Jinko solar modules to tie in nicely with the roof.

Here we are using Enphase Micro inverters to manage the solar energy and an Elios Power Reducer to divert excess solar energy into the hot water cylinder rather than the grid.


This is a job we complete in Otaki, North of Wellington. This is a 3.12kWp grid tie solar system with Tier 1 Jinko solar modules and Fronius Austrian made inverter. We have also fitted an Elios Power Reducer to divert excess solar energy into the water cylinder.

Foster – Recent Installs

This is an installation of a 3.12kWp grid tie solar system in Waikanae, North of Wellington.

This system has Tier 1 Jinko solar modules and Enphase Micro inverters to manage the solar energy. With Enphase Micro inverters each solar panel has its own inverter instead of 1 larger string inverter managing the entire system.

As usual we have also fitted an Elios Power Reducer to divert excess solar energy into the hot water cylinder instead of the grid.


This is an installation of a 4.16kWp grid tie solar system in Nelson with Enphase Micro inverter technology. This client did not have a North facing roof and so we have fitted an array on both the East and West roofs instead. The Eastern system will start to operate first, then both work together from around 10am and then in the afternoon the Western array will operate until later in the evening.

Solar Electric Technology Ltd provides services including installation of solar heating and solar power panels throughout New Zealand and Australia. We make solar heating accessible to homeowners and businesses alike. Whatever your solar heating needs are, we’re here to help you. We make solar heating super easy for you.

Marlborough District Council Flicks Switch On Solar Power Scheme – Media Statement

Good news for Marlborough ratepayers! Switching to solar power is now easier thanks to the newly launched initiative by the district Council.

On 15th April 2019, the Marlborough District Council has released a media statement saying ratepayers wanting to go solar can now call on Council for assistance. You can opt to add the installation costs of your solar panels to your rates bill, provided that you use an approved supplier.

The payback scheme involves a targeted rate over nine years, plus an administration fee and a 5.5 per cent standard interest rate (to be reviewed annually).

Eight approved solar panel providers have been identified by the Council through an Expression of Interest process. Council’s Chief Financial Officer Martin Fletcher says all providers are members of the Sustainable Energy Association New Zealand (SEANZ), which assures a high level of quality to their work.

If you’re ready to go solar, you can obtain quotes from the abovementioned providers. When comparing quotes, keep in mind that installation fees will depend on the type, size and number of solar panels you need. Be sure to check the quotes thoroughly to ensure you aren’t comparing apples to oranges.

Once you have obtained a satisfactory quote, you can go to Council to apply for assistance. This is open to all Marlborough ratepayers regardless of their income or assets.

Martin says the scheme is part of the Council’s suite of energy efficiency initiatives – solar being a natural extension given the district’s abundant sunshine hours.

While the prices of solar panels have dropped significantly over the years, the installation costs are still somewhat of a hindrance for some homeowners and businesses. The installation work is one of the major factors that would affect the performance of solar panels. But because many existing homes and buildings were not designed to accommodate solar features, installers often have to set up support brackets and sometimes create out-of-the-box solutions to make sure homeowners reap the highest ROI possible.

Solar is one of the best and most sustainable methods to power homes and businesses. Once you have your solar system installed, it will operate reliably for the next two decades with little or no maintenance. The best part is that solar energy is free, abundant and environment friendly.

With this newly launched initiative, the Council hopes to improve the affordability of clean home heating and power supply. More information about the available energy efficiency funding services can be found here.

Solar Electric Specialists: What To Look For Before Committing

From choosing the right solar electric system to determining the correct size of the photovoltaic solar panels and obtaining the necessary permits, going solar is complicated. You need a company that knows their stuff well and cares about your investment as much as you do. A solar electric system is a substantial investment and something that you’ll be living with for a long time.

Finding solar electric specialists is easy, but choosing a good one that meets your needs and expectations is a different story. To thoroughly vet potential solar companies, check if they fit the following criteria:

Licence and insurance

Obviously, the very first thing to check is whether the company has correct and valid licence and is appropriately bonded. In addition, you want to ask straightforward questions about the type of system that they think will suit your property and power consumption. You want to make sure they are going to install a customized solar array configuration that maximizes the amount of sunlight available in your location to save you the most money possible, not a cookie-cutter one.

Realistic quotes

You often get what you pay for. So if you are quoted a price that’s substantially less than most other similar sized systems, the equipment and/or the installation work you’ll receive might be of poor quality.

To check for quality, you can ask the company for similar projects they have done before and ask for client references. Are their clients satisfied with what and how the company delivered for the price they paid? A good company won’t find any problem providing client references, because they are confident about the quality of their work.

Solar panel certification

A certification indicates that the solar panels have met their advertised specifications. This can be done by an independent laboratory or by the company itself. If the solar panels are self-assessed, you can only rely on the company being honest with their claims.


Many companies will say what you want to hear in order to get your business. What you need is someone who can and will explain to you all the nitty-gritty of going solar, like how much you can save with a particular system or if your property is appropriate for solar.

Speaking of transparency, here are some important questions to ask potential solar system providers:

  • How does the system work in extreme weather conditions?
  • What are the solar panel efficiency and degradation rates?
  • How long will I recoup my investment?
  • What types of solar power systems do you carry and how do they differ?
  • Which system would you choose for your own property and why?
  • What’s included in your quote?
  • How does your warranty work?

Length of Warranty

Most solar power systems will last around 25 years. So you can expect your solar system to last a long time – typically long enough to pay for itself and give you returns. The industry standard for most installers is five to ten years, but some will offer up to 20-25 years workmanship warranties covering the lifetime of the system.  These extended warranties will add cost to the installation.

Solar systems require minimal maintenance, and very few things can go wrong since there are few moving parts. However, if something does happen, you need that warranty to cover for the maintenance and/or repair costs. But for a warranty to be honoured, the installer must still be operating. That said, you need to ensure that the company will remain in business for as long as your warranty is valid. How? The best way is to choose an established company that has a good track record and reputation because this is the type of company that will stay around for a long time.

Positive reviews

People leave reviews on companies for two reasons: they were disappointed or they were very pleased with the quality of product/service they received. If a company gets a lot of positive reviews from verified customers, you can take that as a good sign.

Of course, there are also those who leave nasty comments just because or use fake accounts to polish the image of the company. So you have to be discerning and intuitive when reading reviews.

New Zealand’s Renewable Energy Resources

New Zealand’s energy production comes from both renewable and non-renewable sources. In 2016, about 85% of electricity generation came from renewable sources, marking the country’s highest production level in 35 years.

Renewable energy comes from sources that replenish naturally in a considerably short period of time. The country’s renewable energy supply particularly comes from geothermal, hydro (24%), biomass (17%), wind and solar power.

Aspiring for a future with a secure and resilient renewable energy supply, the NZ government has put into place research and development initiatives to economically grow its renewables supply. Electricity renewable percentage is trending up since the mid-2000s due to the continual market development, declining costs of renewable technologies and the downgrading of Maui natural gas reserves.

The country has significant advantages in electricity generation, given its vast renewable resources from windswept landscapes to volcanic features and generous sunlight hours. Currently, NZ has the third highest renewables percentage of total primary energy supply (TPES) in the OECD, next to Norway and Iceland.

Below are the types of renewable energy sources that make up the country’s supply:


New Zealand is located strategically between two tectonic plates, meaning it has vast potential for geothermal power generation. The Earth’s crust is thinner along faults, so the hot mantle is much closer to the surface. The heat generated and stored in the ground is what we call geothermal energy, which supplies 17 percent of the country’s electricity and 22 percent of our TPES.

Geothermal fluid, which is a mixture of high pressure water and steam, is piped from deep wells to a central generation power plant where it is turned into steam. The steam is what drives turbine generators to produce electricity. 

Since it’s not weather dependent, geothermal energy supply is consistent and reliable. However, careful monitoring and management of water and pressure levels in the power station are necessary to prevent land subsidence and depletion. This generation method does produce greenhouse gas emissions, but still at a relatively lower amount than the cleanest natural gas plants.

Hydro power

Hydro power generation is the backbone of New Zealand’s electricity system, contributing more than half of our electricity supply.

Hydroelectricity plants rely on gravity to drive water from nearby streams, rivers or dams through turbines, which drive power generators. The process is fast and gives off no greenhouse gases, however there are environmental repercussions to building dams.

The challenge with hydro schemes is New Zealand’s lack of water storage capacity and variable water supplies. Fortunately, the growing wind farms and solar power systems are easing these concerns.


Wind turbines harness wind power and convert it into electricity. With the country’s vast landscapes, wind-powered generation is a very promising form of electricity generation. It is one of the most environmentally friendly methods as well, given that wind turbines don’t produce greenhouse gas emissions during operation. That being said, wind energy only accounts to two percent of New Zealand’s total renewable energy supply.

Three quarters of Kiwis support wind farms, but there are objections to the sight of them and the noise they create. This has led to stricter building codes for farms as well as noise standards for turbines to ensure quieter operation.


We use either passive or active solar power systems to harness the sun’s energy. Passive systems use architecture and engineering to design homes to absorb solar radiation for heating spaces. Active systems use photovoltaic (PV) solar panels to generate electricity as well as solar water heating devices. Solar panels consist of light-sensitive cells that absorb sunlight and irradiance to produce electricity.

Solar electricity is silent, unobtrusive and sustainable. It is the underdog among all of New Zealand’s renewable resources. While it’s totally free and can be used all around the country, it currently amounts to only 2 percent of the total primary renewable supply.

The benefits are definitely there, but there are apprehensions to its uptake primarily due to the high capital cost of solar power systems. Another hindrance to its utilisation is that solar PV is branded as a ‘disruptive technology’ because it challenges the conventional model of electricity provision. However, newer technologies and price reductions in solar PV equipment are making solar power more efficient and affordable to own. And the ever-increasing prices of electricity are pushing more Kiwis to adopt solar as an alternative power generation method.

In fact, there are a number of island resorts that installed their own off-grid solar power plants to cut costs and gain energy independence. On the other hand, householders and property owners prefer grid-tied systems as they need backup power from the grid when the solar panels aren’t generating power at night.


Bioenergy is fuel made from biomass feedstocks, which are renewable organic materials such as trees, residue wood, crops and by-products like straw, manure, sewage, etc. This type of energy contributed to 7 percent of our TPES in 2015.

Biomass can be burned to provide process heat, which can be used directly or used to generate electricity. Residue wood can be burned to produce heat for domestic use, although this practice is used primarily in the timber industry.

Alternatively, biomass can be turned into liquid biofuels for use in transport. The most common types of biofuels are bioethanol (a type of alcohol fuel processed from waste and organic by-products) and biodiesel (made from animal fats and vegetable oils). Biofuels help make our vehicles cleaner and gentler on the environment.

The current issues with bioenergy are the costs of gathering and transporting biomass feedstocks. Nevertheless, recent innovations are making it easier and cheaper to produce biofuels on a mass scale.


Solar Solutions from New Zealand for New Zealand

It’s the best time for a more sustainable home. As you are well aware of, electricity prices are continuously rising each year, while the cost of solar energy systems have been dropping.

Switching to solar today makes real sense. This goes without saying that you need the right solution to meet your specific energy requirements. The good news is you don’t have to go far and wide to search for a reliable solar equipment supplier. The best solar solution or your home or business can be met by Solar Electric Technology Ltd, a home-grown solar specialist.

Solar Electric Technology is 100% Kiwi-owned and operated. We have offices and installers across main centres in New Zealand. Our world-class systems are designed and engineered right here in NZ, and everything is tested locally as well.

What does this mean for you?

This means that the system we will install for your home or business will perform optimally in our local conditions. Optimal performance means maximum power generation and efficiency, which in turn means you’ll get the best return for your investment.

Whether you want to power your home using solar or you want to save on your hot water heating costs, we offer total energy solutions to meet your requirements.

To make your solar upgrade stress free, we do everything for you:

  • System design
  • Installation
  • Plumbing
  • Electrical certification
  • After-sales service

In some cases, a building consent is required for installing PV panels. For example, if you are planning to install PV panels as your roof cladding. You may also need a resource consent if your property is in a special interest or heritage zone or if your roof-mounted panels exceed height-to-boundary restrictions. But don’t worry because we’ll also take care of this on your behalf.

For residential properties, most of the systems we install are grid-connected PV solar systems. While it can generate most of your electricity demand, it allows you to draw power from the grid when your solar generation is not enough. If you generate more than you use, you’ll be able to export your excess power back to the grid and get paid by your utility retailer. The systems we design are scalable so you can add more PV panels over time as your energy demands increase.

On the other hand, some of our clients ask for an off-the-grid solar system which makes them completely independent from the national grid. It costs more than a grid-connected system since it requires a few additional components such as batteries and backup generators. Neverthless, they aren’t affected by power outages or increasing power bills. It’s also an ideal solution if you are located far from the electricity lines, as connecting to the grid becomes a more expensive option.

Solar-powered hot water heaters are also popular among Kiwis. We’ve installed hundreds of advanced technology evacuated tube solar collectors that are ideal for high hot water usage.
