Fantastic experience

How could I NOT install solar on my roof with zero down and a monthly payment that right from the start is lower than my average electric bill? That was a bit over three years ago, and we’ve paid the utility company NOTHING for electricity since then. Our spring/summer/fall excess production covers the winter shortfalls. Amazing to receive a utility bill in February with NO charge for electricity!

Testimonial

Pays for itself

When it came to choosing the right solar panels for my house, I had the benefit of being an engineer with a Masters Degree from the Solar Energy Laboratory at University of Wisconsin-Madison and working for an engineering firm. We have conducted our own internal studies and I knew from those studies, that the Sunpower panels tended to outperform other manufacturers.
