A
PV solar system is made of three key components:
1. PV Solar Modules (Panels)
Solar
electricity is produced when sunlight strikes
the surface of the panels. The electricity is
produced in DC form, much like a car battery.
2.
Inverter
Converts
the DC power produced by the panels into AC power.
This is used by your home or business and by the
PG&E grid.
3.
PG&E Grid Interconnection
Your
system is physically connected to your PG&E
meter to provide excess power for sale back to
the utility. When it’s making more power
than you are using (mid-day or late night) your
meter will spin backwards, which reduces your
bill. And if your system produces enough power
your PG&E electric bill will be ZERO!
NOTE:
additional equipment is needed to mount the panels
to a fixed surface, concentrate the electricity
coming from the modules, and control the interactions
of the inverter and the utility grid.
