SOLAR ELECTRIC POWER GENERATION
Solar Electric Power can be generated varying from 100 Watts small
solar home systems to 100 MW Solar
Power Plants or sometimes more than that. The solar power systems
are of two types; one is off-grid and
other is on-grid systems. In off-grid systems, the system has no
link with Utility grid and components used in
Systems are Solar Panels, Charge Controllers, Inverters, Deep Cycle
Batteries, mounting and electric
accessories. Solar Panels convert solar radiations into electric
current and this current passes through
charge controllers which charges the battery by controlling current
for the battery. Charge controllers
maintain control on charging the battery for its long life. So the
DC power is stored in Batteries and this
stored energy is converted into AC Power to operate the AC
appliances. The DC appliances can be
operated directly with the battery. So DC and AC load can be
operated through a solar power system.
