There are many terms used in the electric
solar energy industry which you may not be familiar with. In order to help you
understand the information presented to you, or which you discover through your
own research, we’ve put together another post with more detailed explanations
of some common terms you may stumble across.
Module power ratings: Module power ratings
refer to your solar panel’s electric solar energy output. The STC-DC (Standard
Test Condition Direct Current) rating is the global standard for rating a
panel’s output, and tests panels using ideal laboratory test settings. The
CEC-AC (California Energy Commission Alternating Current) rating uses realistic
conditions to measure a panel’s output, as well as inverter efficiency. The
CEC-AC rating is always lower than the STC-DC rating because of the difference
in testing conditions.
PACE: PACE, or Property Assessed Clean
Energy, is a program administered through municipalities which allows residents
to finance the installation of an electric solar energy system by paying for it
through annual property tax bills. These programs can have higher interest
rates than other solar financing options.
PPA: A PPA, or Power Purchase Agreement, is
a method to finance the installation of an electric solar energy system.
Through a PPA, you will purchase the energy produced by your electric solar
energy system at a flat rate. The solar equipment is owned and maintained by
the provider, which means you benefit from the energy produced without added
maintenance and installation costs.
Prepaid lease: A prepaid lease is another
option for those who want to utilize electric solar energy, but don’t want to
purchase the system outright. By prepaying for the use of your system for a
predetermined time period, prepaid lease providers warranty the system, and you
are able to use the electric solar energy produced by the system during that
time period.
