The Basics of a Solar Electric
Power System
Solar systems begin
with the solar module. Modules gather solar energy in the form of sunlight
and convert it into direct current (DC) electricity. The more sunlight
they receive, the more electricity they produce. Solar modules are the
heart of the system. They are the power generators.
Components such
as charge regulators, batteries and inverters regulate, store, condition
and deliver the electricity. Other elements connect the different components
of the system.
Solar systems have
to meet high standards of reliability and economic efficiency. This can
only be guaranteed by the use of field-proven quality components that
are well matched.
| Sunlight
|
Sunlight
is energy in the form of light. It is the fuel of a solar (photovoltaic)
system. |
| Solar
Modules |
Solar
modules generate DC electricity directly from sunlight. Use
one or more modules depending on your power needs and the amount
of sunlight available. |
| Charge
Regulator |
Charge
regulators are the link between the modules, battery and load.
They protect the battery from overcharge or excessive discharge.
|
| Battery
|
Batteries
store the energy generated by the solar modules. |
| Inverter
|
Inverters
convert DC (direct current) electricity into AC (alternating
current) to run many common appliances and equipment. |
| Mounting
Structure |
Mounting
structures hold the solar modules securely in place. Ground,
roof and pole mounting versions are available. |
| Load
|
The
appliances, lights and equipment being powered are called electrical
'loads'. Energy-efficient loads contribute to overall system
efficiency and economy. |
| Wiring
/ Interconnects |
Proper
wiring and connections must be specified for every segment of
the system to assure best performance. |
| Back-up
Generator |
Compatible
generators (e.g. diesel) may be used as back-up for excessive
power demands or during unanticipated long sunless periods.
|
| Space
|
Solar
modules should be installed in an area that is generally free
from shade and receives as much direct sun exposure as possible.
|
| Maintenance
|
Solar
systems are one of the easiest and most reliable ways to generate
electricity. Regular maintenance to check wiring, connections,
batteries, and overall system condition will help assure long-term
trouble-free operation. |
