Elements
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
Module |
Solar
Modules generate DC electricity differently from sunlight. Use
1 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) electricity 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 (ie 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 conditionl, will help assure long-term
trouble-free operation. |
