Frequently Asked Questions

The answers to common questions we get about solar power systems.

  • How much money will I save?
    There is a bit of skepticism around solars ability to generate savings. However, with recent developments in solar technology and batteries, users can expect significant savings on their power bills over time. To get a quick idea for residential installations, see our return of investment (ROI) from solar panel efficiency. Your solar investment will largely be dependent on how much energy you use. Our team, however, have the knowledge and software to put together proposals forecasting your installation costs and ROI. Get in touch today to learn more!
  • How does solar technology work?
    Solar PV panel systems use cells to convert sunlight into electricity. The panel collects the sun’s energy and makes direct current (DC) electricity. An inverter changes the DC electricity into alternating current (AC) electricity, which most homes use. The inverter is a metal box connected to a meter, which in turn is connected to the utility’s electric grid.
  • How much does a solar system cost, and what financing options are available?
    The total cost of an installed solar system varies depending on your energy needs and the size of your property. For residential and small businesses, you can use the free SEANZ Solar Optimiser to calculate the system cost and how to maximise your savings. We offer three payment solutions; cash purchase, finance purchase, and a power purchase agreement (PPA). For more information on our payment plans click here.
  • How do I know what sized panel to purchase?
    This will be calculated by our very competent team, and is site specific.
  • Why would I add batteries to my system?
    Adding a solar panel battery to the system will help with night usage – less power will be fed into the grid which in turn will be stored and used by the user. Also, you will only be able to operate from the battery power if there is no power supply (sunlight).
  • What kind of servicing does a solar system need?
    Essentially there will be no maintenance needed on the solar system, but like any other electrical installations, regular maintenance is important such as checking connections and cleaning.
  • Will the system work in very cold weather?
    Yes, the system will work in all parts of New Zealand. In fact, they work even better when it is cold as the cells lose efficiency in hot conditions. However, it will not work if the panel Is covered in snow as this will prevent light from striking the absorber plate.
  • Is it possible to have commercial solar panels?
    Yes. Using solar panels at your Auckland or Christchurch business can help save your company money while also being good for the environment. We are experts at commercial and industrial solar panels and our technicians can custom design a system that suits your specific industry and your energy needs. We offer a free monitoring system for commercial solar installations so you get maximum solar efficiencies and ROI and our solar panel specialists are always on hand to offer advice.
  • Can I sell my excess solar energy?
    Absolutely! You can sell any excess solar energy you produce back to the grid and your utility company will give you a credit on your power bill. This is known as a solar buyback. As a rule of thumb, you can expect anywhere between $0.07 - $0.17 per kWh of electricity exported.
