What You Need to Know
Grid tied PV and PV back up For pictures and description please go to http://www.mtholyoke.edu/~jhoward/solarenergy.html The house was built in three sections. It has large southern facing windows so that the gas furnace seldom turns on during a sunny day. The PV system was used for a 12 v back up and is being added to and connected to the grid.
Fixed energy costs for car, house and water heating land electricity. Plus no concern over gas shortage for the car.
Chevy Volt none, Love it! Very little on the rest.
Efficiency or Sustainability Improvements:
Loose Fill Fiberglass Energy Star Appliances, Passive solar house, Recycled Materials
Two years in the Peace Corps, India.
You can make this change slowly if you do not have the money all at once. I did the PV in six installments over five years.
Experience with Installer:
PV Squared unsatisfied Solar Store of Greenfield very satisfied
