Craig's a scientist, he came to us with a very specific brief on what he wanted. Craig wanted to have the panels in landscape. He wanted them on the north-facing roof to fill the north-facing roof as much as we could. Craig picked the panel because it was the highest-efficiency panel on the market. Being a scientist, he had conducted a lot of research into the product. He has also requested that he wanted the micro-inverters, which paired together, make a very good system. The main challenge was the roof. The purlin spacings weren't correct, so we had to use a special bracket, a W bracket to screw it down to the roof, using EJOT screws and bits and pieces. So it was a bit of a challenge. On a good day it's generating 100 kilowatt hours a day, which is quite considerable amount for residential property. But with his plans to add a substantial battery storage, he felt that he was future-proofing.
