Efficiency or Sustainability Improvements:

Spray Foam Closed Cell Energy Star Appliances, Heat recovery ventilation, Instantaneous hot water, Passive solar, Radiant floor heating, Rain Barrels, Super Insulated Walls/ Roof

My Motivation:

To live sustainably.


Microinverters offer substantial benefits such as per-panel performance data and about 8% increased efficiency compared to string inverters

Experience with Installer:

I engaged neighbors and friends to help install the system and they all enjoyed learning how a solar power system works and goes up.

Additional Notes:

Had to install on a west facing (270 degree) roof since we did not have any south facing roof surface. This required about 25% more panels, and it worked out fine.
