"Best panels with the best warranty "

"Awesome!"

These panels have produced more than 100% of my needs for the past 3 years. I bought them because they were the most attractive option for the front of my home and that they have the best warranty.

"Great panels but expen$ive"

I think it's clear Sunpower makes the best solar panels, but you pay a price for them. My prediction is that the technology will keep getting better, and in 10-15 years you may want to upgrade your system anyway, so why would you pay a lot for premium panels with ...
