How much can you generate?

What affects your solar system cost?

If your household has a high energy consumption (big house, pool, spa etc) you will need a larger system with more solar panels to meet your needs. Conversely, if your energy usage is lower, a smaller system will be enough.
The quality and performance of solar panels, inverters and home batteries play a significant role in determining the overall cost of a solar system. Invest in higher quality panels with superior efficiency rates, known brand name and a credible warranty - they can generate more electricity over their lifetime and provide a greater return on investment + piece of mind with NZ supported warranties.
Different roof types or site requirements may impact the cost of a solar system, this could be things like extra wiring, scaffolding, ground-mounted panels, specialized mounting structures or if you have a roof with limited space or unusual angles - but don't worry, we've seen it all  before and our expert team can help.

Frequently Asked

All your Solar questions answered

Will Solar work in NZ?

Absolutely! New Zealand has abundant sunshine and generates between 1,700 and 2,100 sunshine hours annually. Some areas, like Nelson and Gisborne, receive as much as 2,400. Solar Panels don’t require sunshine; they require daylight, so Solar Panels work year-round, even in the lower South Island.

How many Panels do I need?

The average energy consumption is essential in determining the number of Solar Panels you need. A retired couple will have a different power consumption than a young family, plus pools, spas, and electric cars can also impact energy requirements.

The amount of energy Solar Panels can generate depends on sun hours and is therefore affected by your location.

Your roof size is crucial because it determines the number of Panels that can fit on your roof, how much energy will be generated, and the cost.
