Exceptional Service and Expertise: Julian Delivers Stellar Solutions for Your Solar Needs!

I've fitted a Harrisons Solar System, and it works well. But I had a few outstanding questions that needed answering, and was extremely pleased when Julian went out of his way to look into these and solve then very quickly and professionally - most impressed! And would recommend him to anyone that needs someone that knows and enjoys their trade inside and out.

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.
