PV SYSTEMS
OUTCOME 2

Types of PV Systems
 The three most common types of photovoltaic systems for residential solar
power are...
 Stand-Alone PV System
 Grid-Tied PV System
 Grid-Tied PV System with Battery Backup

Stand Alone PV System-Advantages
 Stand-alone PV systems are designed to operate independently from the grid
and to provide all of the electricity you need for your home.
 If you have a home that is in a remote area that doesn't have utility grid
service or where it would be very costly to have power lines run to your
home, a stand-alone PV system would be ideal.
 This type of PV system is also desirable if you are looking to go completely
green with your source of electricity.

A grid-tied PV system-Operation
 A grid-tied PV system allows you to use the electricity generated by your PV
system as well as electricity from the grid.
 When your PV system is producing electricity, your home will be powered by solar
electricity. During the times when your PV system isn't producing electricity, such
as at night, your home will receive power from the grid.
 Any excess electricity produced by your system can be fed back to the grid. This is
known as net-metering.
 With net-metering, when you use electricity from the grid your meter spins
forward and when you are providing electricity to the grid your meter spins
backwards.
 This offset means you are actually receiving market rates for the electricity you
provide to the grid
