Structure & Mounting Issue • Dead Load: self-weight or permanent load on a
structure, e.g. Roof structure, Bridges • Live Load; People on the roof, cars on the bridge,
repair equipment/materials • Wind Sheer: e.g. wind force on HVAC equip, on
Panels and structures • Seasonal Load: Snow, Rain, Hail • Vibration: HVAC motors, Fans, wind through Panel
structure • Seismic forces • Soil composition, landfills • Floating Structures on water..!

AB 920 NEM • In 2009, the California Legislature passed and
Governor Schwarzenegger signed into law Assembly Bill (AB) 920, which changed the law that governs Net Energy Metering (NEM) for solar and small wind generators.
• Before the change, the law said customers could not receive credit for electricity exported to the grid beyond their own annual usage.
• As a result of AB 920, customers can receive compensation or a credit for net exports to the grid at the time of their annual true-up starting in 2011.
NEM Options If a customer generates more electricity during his or her 12-month true up period (that ends 2011 or thereafter) than it is supplied by the electric utility to the customer during the same 12-month period, the customer may elect to do one of the following:
(A) Receive compensation for any net surplus electricity generated during the 12-month period, or
(B) Apply the net surplus electricity as a credit for kilowatt-hours subsequently supplied by the electric utility to the surplus customer-generator, or
(C) Not participate.
