Efficient Solar

The efficiency of the solar panels and seeing how much solar energy our home really did generate was the most surprising. It’s exciting to get an electrical bill every month and see a zero!

Sunpower is a good investment

I compared the value of my solar investment versus a hypothetical 7% per year gain in stocks and bonds. Over a 10-year period I’m expecting to come out ahead. So solar was a good way to diversify my investments.

Thick Connectors

Maxeon cells expand and contract. Daily temperature swings are no problem with our built-in strain relief.

Metal Lines on Cell

Conventional cells power output drops as the thin paste reflects light and corrodes.
