We've got a six kilowatt system here because we run two houses off the system. We have 20 x 300 watt solar panels on the roof, and we have a 400 watt wind turbine that is hooked into the system to back up the batteries afterwards. We have 24 batteries in total and we have a 9.4 KVA generator to back up the system when we have very cloudy or rainy days. I did a lot of research into the panels and looked at the range of what was available and listened to a lot of the experts in the field.

Panels that were recommended for this system were the best that we needed at the time to give us the six kilowatt system that we needed for the two houses. We put the system in five years ago, and it was the top quality that when we put the system in. And I've been very happy with the service that we've had from the system, we haven't had any downtime with it. I think that it's worth doing the research and finding out the best system for your area and the best quality. Long term it pays off, because it will last longer and you get better service.
