Canadian Solar 270W Mono BLK/BLK Solar Panel T4 Connectors (Pack of 4)

I've Bought 10 of these Solar Panels now and am VERY please with them. Very good build quality and the output is really quite good. As soon as the light of day comes around these panels start delivery power, and in direct sun they produce very close to the stated specifications. Getting set up with a solar generating system including a transfer switch to supplement house power is STUPID expensive, but in a power outage/grid down situation, its seems worth it to me. We just had a power outage of about 6 hours and didn't even notice the difference. Right now, the 6 panels I have are generating about a third of my house power, which is saving some money, but I will never see a payback in my lifetime. STUPID expensive....
