the intensity of the light, the more current a solar cell generates.
How PV cells work is that the current moves through a series of
cells, called modules, to a battery where it is stored. Battery
storage assures the user of electricity when needed, day or night.
A controller is usually installed between the modules and the battery
to prevent overcharging. Linked together, this equipment forms a
PV system designed to produce 12 or 24 volts of direct current (DC).
of an inverter the direct current is turned into alternating current
(AC), the standard home current with which we're all familiar. DC
to AC inverters now provide outputs ranging from 100 to 20,000 watts
at conversion efficiencies greater than 90 percent and with cleaner
power than the utility company can provide (good to know for those
looking to buy electric solar panels).
Any number of
solar PV modules can be connected in an array to supply your present
load requirements on or off-grid arrangement. The array may be expanded
easily by adding modules to meet future power needs. Once installed,
the modules are maintenance free. An occasional rinsing is all that
PV units can be integrated seamlessly into
