Solar Electric Basic Components
1. Modules solar electric collectors. 3 basic
types in the marketplace Mono crystalline, poly
crystalline, thin film2. Array modules
connected together into a system   3. Inverter
converts the DC power produced by the modules to
A/C 4. Grid Tie Inverter converts DC to AC and
feeds the utility grid with the A/C power   5.
Charge Controller regulates the power going to
the batteries 6. Batteries stores DC power

Solar Electric Types of Systems
Each type has very specific capabilities and
limitations All PV systems consist of one or more
modules which produce DC power.  It is what is
done with this power after it is produced that
determines the type of system.   Stand Alone
Off grid Modules, charge controller, batteries,
and may or may not have an inverter which
converts DC power to A/c power   Grid Tie Grid
connected Modules, and inverter connected to the
power grid   Hybrid Grid connected with
batteries Modules, grid-tie inverter, and
batteries for storage when the grid is
unavailable Systems can be installed on roofs,
ground racks, pole mounts, or on racks which
track the sun.

Stand Alone Off Grid Systems

• Stand-alone PV systems are designed to operate
  independent of the electric utility grid, and are
  generally designed and sized to supply certain DC
  and/or AC electrical loads.
• Common applications are direct power to DC
  loads, water pumping and telecommunications.
• With an inverter it can also power AC loads
• For systems with no battery the energy is used
  immediately only works when it's sunny  

Systems with Battery Backup can supply power 100
of the time At night, on cloudy days and when
the utility power is down

Grid Tie Grid Connected Systems
Grid Tie System is the simplest and most cost
effective way to connect PV modules to regular
utility power. Grid-Connected systems can
supply solar power to your home and use utility
power as a backup. As long as there is enough
electricity flowing in from your PV system, no
electricity will flow in from the utility
company. If your system is generating more
power than you are using, the excess will flow
back into the grid, turning your meter
backwards.

Hybrid Grid Connected with Batteries
If utility power is reliable and well maintained
in your area, and energy storage is not a
priority, you don't necessarily need a battery.
But if the utility power goes down, even if there
is solar, the PV system will be off for the
safety of the utility workers. Systems with
Battery can supply power 100 of the time.

19
Net Metering
With Net Metering you can benefit from laws and
regulations that require "net" electric meter
reading. How it WorksThe customer is billed
for the net electricity purchased from the
utility over the entire billing periodthat is,
the difference between the electricity coming
from the power grid and the electricity generated
by the PV system. Through net metering, the
customer obtains the full retail electricity
raterather than the much lower wholesale
ratefor kilowatt-hours of PV- produced
electricity sent to the utility power grid.
