Help, which panel to use?
Hi, I am working with two vendors in the NJ area. One is trying to convince me to use Evergreen the other Sunpower. The Evergreens I know are a little larger and I will not be able to put quite as many on my roof but will still be able to install an adequate system 8.1kw system. The Evergreen's installed are coming in at $6/kw and the Sunpower at $6.5/kw. Same warranties. Is one panel better than the other. Will be using the 210s. Thanks.
