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.


What are the benefits of an “Off The Grid” solar system?

In one of our previous blog posts, we covered what a grid connected solar system is and how it can benefit your home. Now it is time to consider an "off the grid" solar system and why it may be the system for you.

Firstly, what is an off the grid solar system? An off the grid solar system is a system that is designed to work on it's own. It is not connected to the mains power supply or any other power grid. It solely relies on the solar panels, wind turbines or micro hydro system to produce the power  which then stored in batteries. Like every system, it has it's advantages and disadvantages.

Advantages of an off the grid system are that you are completely energy independent, meaning that you don't get the negatives that come with using the main utility grid, such as power outages. An off the grid system can be installed virtually anywhere, as long as there is sun. It stores the electricity provided so you will always have electricity to use provided that there is enough stored. You will not be recieving any power bills at all with an off the grid system because it is independent, making it a free power solution for your home.

There are some disadvantages with this system however. Because you are power independent, if your system doesn't produce enough power, you don't have other option. This is rarely a problem however, and if the system has been designed properly, you should not experience this problem. An off the grid system can cost a bit more than a grid tied system too. Another disadvantage is that an off the grid system produces less power than an equal grid tied system of the same size in the same situation. This is due to the way the system and batteries work. And when you have filled the batteries, all the power that is being produced has no where to go, so it is essentially wasted.
