SunPower Solar Panels?

Do higher watt solar panels last longer, efficiency-wise?

3 installers gave me quotes with 3 different sunpower panels. The 225, 215, 210 watt panels.

Whats the con and pro's of the different wattages?


There is no difference between them besides their rated output. One may physically fit on you roof better than another, or look better, although the physical difference between those sizes is minimal. Go with whichever installer you trust, and is preferably NABCEP certified, or working towards NABCEP certification. Get references. Don't believe just because someone is an electrician they know how to install solar electric, it's a whole different animal. Make sure they are trained in installing solar.
