Solar System
When power is supplied to small loads,
diesel generators are too expensive in long-term operation. Subjected to
mechanical wear and tear, they also need regular refueling and
specialized maintenance. After a while, they need to be replaced.
A better alternative is solar energy.
Reliability, low-maintenance, and the ability to deliver power in
practically any environment make photovoltaic ideal for cost effective
use in systems such as telecommunication.

Solar Cell Mechanisms
A solar cell is made of 2 types of
semiconductors, i.e. N-type (more electrons- negative charge) and P-type
(more holes- positive charge) semiconductors. These are bonded together
and an electrode is attached to each of them.
When the solar cell is exposed to
sunlight, both negative and positive charges are created. The former is
segregated to the N-type while the latter is segregated to the P-type,
producing a potential between the 2 electrodes. When a solar cell at
this state is connected to an external load such as an electrical bulb,
the electrical current flows and the bulb lights up.

Solar System Components
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.

Regulators, Inverters & Batteries
While batteries store the energy generated by the
solar modules, charge regulators are the link between the modules,
battery and electrical load. They protect the battery from overcharge or
excessive discharge.
Inverters convert DC to AC electricity which is used
to run many common appliances and equipment. |
Mounting Structure & Interconnects
Mounting structures hold the solar modules securely in
place. Ground, roof and pole mounting versions are available.
Proper wiring and connections must be specified for
every segment of the system to assure best performance.
Solar modules should be installed in an area that is
generally free from shade and receives as much direct sun exposure as
possible. |

Backup Generator
Compatible generators (i.e. diesel) may be used as
back-up for excessive power demands or during unanticipated long sunless
periods. 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.
