What You Need to Know


The system is 18 Canadian Solar CS 245 with the Enphase 215.

Maintenance Requirements:

I don't believe any maintenance will be required. I haven't had any problems yet, but it was only installed a month ago. In any event, the products are warrantied for 25 years.

My Motivation:

I was motivated by the desire to reduce (actually, eliminate) my future electricity costs and to benefit the environment.


I would take full advantage of local resources during the "investigation" phase of the purchase. I found the Cambridge Energy Alliance and Energy Sage to be hugely helpful in guiding me through the process.

Experience with Installer:

Real Goods Solar did a terrific job on the installation. They were completely professional and accessible throughout the entire process. My contact person in Colorado, while always pleasant and eager to assist, was not always well enough informed to answer my questions, however.

Additional Notes:

I initially had four proposals. Three promised that my system would generate 100% of my electricity needs; Real Goods initially proposed a system that would have provided only 65%. Energy Sage went through the numbers and decided that Real Goods actually had the most efficient system and that I should ask them to improve their proposal to 100%. Real Goods did so, and that's why I went with that company.
