ALL SOLAR PRODUCTS ARE NOT EQUAL

U.S. Department of Energy’s Lawrence Berkeley National Laboratory study found that solar homes with an average system size of 3.1kW sold for approximately $17,000 or $5,500/kW more than non-solar homes.

Increased sale price was comparable to the average cost of system installation, and solar homeowners also enjoyed the benefit of lower electric bills.

MORE ELECTRICITY

Solar systems are often described in terms of watts or kilowatts, however, the most important factor to consider is the amount of electricity the system actually produces. This is measured in kilowatt-hours.
