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.

Average Sunlight in New Zealand

According to Statistics NZ, on average, most of the country received between 1,672 and 2,098 hour of sunshine each year from 1972 to 2016. Based on the 2017 Annual Climate Summary by the National Institute of Water and Atmospheric Research (NIWA), the major cities of Auckland, Christchurch and Wellington receive more than 2,000 hours of bright sunlight every year, with the most sunshine hours exceeding 2,600 in the wider Nelson region.

January receives a mean over 200 hours of sunshine due to longer more settled days, while June receives a little over 100 hours due to shorter days and wintery weather.

Turning sunshine hours into energy savings

With solar PV technology, you can harness the sun’s free energy and use it to power your home or business, rather than buy power from the grid. More sunshine hours could mean more dollar savings in terms of energy costs.

Solar generation currently makes up 0.2% of the country’s total energy supply. But price reductions in solar PV equipment have seen an increase in demand with homeowners and businesses.

According to this study, if the trend of falling PV prices continues along with rising electricity spot prices, regions such as Nelson-Tasman (with high irradiance) as well as Auckland, Northland and Taranaki (with reasonable irradiance and higher spot prices) stand to benefit the most from solar PV.

 Why go solar?

One could argue that New Zealand is already rich with renewable energy from wind turbines and geothermal plants, so why the need for solar?

Well, solar PV technology is unique among other renewable energy technologies. It has a massive potential to decline in cost and improve in performance at the same time. In fact, the average turnkey price for a standard PV system of 3kW has dropped from NZ$40,000 to NZ$9,000 since 2009.

Buying power from the grid costs you around 26c to 30c per kilowatt hours, depending on your region. On the other hand, generating power with solar costs about 26c to 28c per kWh (relatively less than it costs five years ago), and this number continues to fall.

PV currently costs more in $z/W or c/kWh than other renewable energy sources. However, it remains an attractive alternative because of its modularity, ease and speed of installation and suitability for a wide range of end-use applications and sites.

According to the Ministry of Business, Innovation & Employment, the potential value of solar is higher than its costs alone would indicate. Although its output is weather dependent on an hourly or daily basis, the power generated is well predictable over longer periods.

Solar PV is a long term investment. It might seem that solar provides little economic benefit at first glance, but the technology actually pays back after 5 to 7 years and continues to save you money for another 15 or 20 years.

To make your investment worthwhile, it makes sense to compare the generation capacity of a solar power system you are considering to the number and intensity of sunshine hours your location receives throughout the year. Our solar experts will be able to help you figure out the potential costs and savings of installing solar for your home or business.

How Sustainable Is Sustainable Energy?

If something is to be called “sustainable” it conveys an understanding that it is able to be maintained at a certain rate or level. As fast as it is used, it is replaced. When we talk about sustainable energy it can make many people feel quite excited that they won’t be contributing to the detriment of earth’s natural resources. But, really, how sustainable is sustainable energy?

First, we must agree on what types of energy are commonly understood to be “sustainable”. The common types of energy that are referred to as being sustainable are:

  • Biomass
  • Solar
  • Wind
  • Hydro
  • Tidal
  • GeoThermal

Sustainable energy has an opposite. The opposite of sustainable energy is called Fossil Fuel. Fossil fuels are a natural fuel such as coal or gas, which has been formed in the geological past from the remains of living organisms. Fossil fuels are slow to develop and time, lots of time, is required in order to have reserves for humans to use.

Whereas in the past life seemed to move at a slower pace, slow and life rarely go hand in hand now. Time is always of the essence and when people want things they want them now, there is no time to wait for geologists to find the next reserve to tap into.

This is where sustainable energy is advantageous. Where fossil fuels have served mankind for centuries, the worry we currently have is how far these fossil fuels can be used considering the fact that they are fast being depleted. Often case when fossil fuels are used, they cause some serious environmental problems which have been shown to contribute to global warming and climate change.

In order for an energy source to be considered “sustainable” it needs to fit within three parameters – environmental, social and economic sustainability. This means that the energy source needs to be able to:

  • Be naturally replenished.
  • Increase its’ efficiency by way of technology
  • Be available long term

Let’s look at the various types of energy that have been identified as “sustainable” and see just how sustainable they are:

Solar Energy
This form of energy almost always comes out on top when looking at sustainable options. Solar energy provides power in two ways: light and heat. Not only can we harness its energy for our day to day lives but solar energy can also be used for plant generation and to help us grow food. Because of this, solar energy systems generate confidence and ensure that how we live does not cause any further harm to our environment.

Wind Energy
Wind turbines can produce vast amounts of power by harnessing our natural resource of wind. Although a relatively new form of sustainable energy, many large companies have started to invest into wind turbines in order to tap into this energy source. In the future, wind power will be able to be on sold to people to power their homes and possibly even industry will be able to be powered. Wind power will allow fossil fuel exploration to stop.

Geothermal Energy
New Zealand is a great country for geothermal activity. The amount of power lying beneath our tectonic plates is undetermined but when you look at places like Rotorua, it is obvious that this is an energy source that we could draw from more so than we currently do. Geothermal energy is captured by installing geothermal power stations that use the heat coming out from inside earth and use it to generate electricity. There is a limitation to Geothermal energy in that it can only be harnessed in areas that have high seismic activity, however they are environment friendly and can produce energy throughout the day.

Tidal Energy
With around 14,000 kms of coastline, New Zealand is literally surrounded by water. On top of this, around 70% of the earth is covered with water. When tidal energy is harnessed correctly, it can be used to power millions of homes. The power of the waves can be used by oceanic thermal plants to convert the kinetic energy in the waves into mechanical energy. Once this has happened the mechanical energy can then be converted into electrical energy for use in homes and industry.

Biomass Energy
Biomass is produced by burning waste. It’s a form of recycling. Biomass energy can be created by burning wood, timber, landfill and agricultural waste. As humans continue to create waste, biomass energy is completely renewable. There is technically no production of carbon dioxide when biomass is made. Yes, burning items causes carbon dioxide but this is compensated for when the plant creating the biomass energy reuse the carbon dioxide created and produce oxygen. The creation of biomass energy also helps reduce the amount of rubbish that ends up in landfills.

Hydro Energy
Hydro Energy, or hydroelectric power, is very common. It is used to generate power in most parts of the world. The energy found in rivers and waterfalls is captured by directing the flow through turbines which generate power. This power is then on-fed through power lines throughout the country to power homes and industry.

Really, any form of “sustainable” energy is our best form of energy to use. Unless the sun stops shining, the moon stops influencing tides, humans stop creating waste to be used for biomass, the geothermal fields dry up and the rivers stop running, sustainable energy is sustainable for the next generation and for millennia.

Today’s Realistic Available Sustainable Energy Options

In a world where the cost of living seems to take massive leaps year to year instead of steady increases, finding ways to make your life simpler and more efficient is high on most people’s priority lists.

The costs associated with running a home, business or recreational enterprise can be crippling. A wise person looks at ways to reduce these costs, therefore allowing hard earned funds to be put to better or different uses.
The market for sustainable energy options has grown and improved substantially of late. But what is available for you and what are your realistic available sustainable energy options?

Largely, it depends on where you are located. However, New Zealand is blessed with options. Wind, Hydro, Solar, Bio, and Marine energy options are plentiful. New Zealand has the added option of geo-thermal power – something that sets us apart from other countries.
Renewable energy comes from sources that are naturally replenished in a relatively short timeframe. Currently, New Zealand sources around 40-45% of its energy from renewable sources.

When looking at your sustainable energy options, make sure you look at each one in depth. Talk to providers. Talk to installers. Talk to people who already have the options you are interested in working for them.

Why look at Solar energy?

Solar is a great option that you can use to complement your traditional power source – the electricity grid. Solar offers long term electricity price stability – this means that when every one panics about power increases you can switch your load to solar and carry on. We can harness the sun’s energy in several ways. Passive solar design is the use of solar radiation to heat our buildings. Buildings that have passive solar design make best use of the sun’s free warmth. Solar panels, also known as photovoltaic (PV) panels, generate electricity directly from sunlight.

Why look at wind energy?

New Zealand has one of the best wind resources in the world due to the windswept nature of our land. Wind energy is renewable, requires no fuel, and cheaper than any other form of new energy generation.
Because wind turbines generate electricity and are easy to remove, and they don’t produce greenhouse gas emissions, this makes wind power is one of the most environmentally friendly forms of electricity generation. Wind energy infrastructure is also fast to build.

Why look at Hydro energy?

The advantages of hydro power are huge. Unlike solar and wind, hydro is stable and continuous – which means you will always get the same input no matter what.

Water stored in dams can be turned into electricity in minutes – a process that gives off no greenhouse gases. Where enough water can be stored, hydroelectricity is reliable and consistent.

More than ever, having access to sustainable energy is a realistic option for many people. Instead of abusing the environment, sustainable (also called renewable) energy allows us to have the comforts we have grown accustomed to in our homes without the ongoing costs. One major advantage with the use of renewable energy is that as it is renewable, it will never run out. Even more importantly, renewable energy produces little or no waste products such as carbon dioxide or other chemical pollutants, so has minimal impact on the environment.
