With Clean Energy Council-approved solar training and certification as a solar electrician, he later returned to New Zealand, settling in the beautiful Central Otago district. Here, he continues his passion for solar energy, helping homeowners experience the benefits of clean, renewable power by installing high-quality solar systems in the local area.

Frequently asked questions
All your solar questions answered
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.
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.
