A
solar generator works in two ways. The first type uses photovoltaic
cells that turn photons from the sun into usable electricity. ‘Photovoltaic’
comes from the word ‘photo’ which means ‘light’,
and ‘volt’ which is a measurement of electricity. Many
small calculators use photovoltaic cells for power.
A photovoltaic cell, or solar panel, works when the sun is shining
and is a great alternative to fossil fuel powered electricity especially
in remote areas where it is difficult to attach to the existing power
grid. As the price of traditional fuels go up, many property owners
are beginning to add solar generators to help defray the costs, even
receiving credits from the power company when there is a surplus of
power.
Another type of solar generator uses heat from the sun to produce
electricity. These generators use a combination of mirrors that move
with the sun and focus light on a heat collector. A fluid running
through the collector gets superheated and then travels to a generator
that runs a turbine off of the steam that is produced. They can be
portable, looking like a satellite dish on wheels, or large power
towers with fields of mirrors and many other variations.
