Factors affecting performance



                      • Climate - the more sun
                        the better

                      • Temperature - cold is
                        good

                      • Shading - none please

               9am to 3pm
             • Consider summer Vs.
               winter sun - which is
               more important?
             • Consider snow issues.

Net-metering; What is it?
  • Utility grid interconnection is made possible by net
    metering rules
  • "Net-metering" means measuring the difference between
    the electricity supplied by an electric utility and the
    electricity generated by a customer-generator

  • Idaho and Wyoming have statutes that requires utility
    companies to accept net metered customers.
    Net metering; How does the customer
                  benefit?


• It allows a building to
  utilize renewable energy
• By “storing” excess
  generation on the grid, no
  batteries are needed
• By eliminating the need for
  batteries, more of our
  investment is in solar
  panels
    Net-metering; How does it work?


Components:

•   Solar panels
•   Mounting structure
•   Solar disconnect
•   AC power disconnect
•   Grid interactive power
    inverter
•   Connection with the AC
    distribution system
•   Utility meter
