Residential Solar Power, to
generate heat or electricity
Residential solar
power - Life on earth is fed by heat and light
coming from the sun. Solar energy makes it way to us via
electromagnetic waves similar to radio waves but on a totally
different range of frequency. Some energy is lost while
traveling thru the atmosphere, but the remaining is sufficient
enough to maintain life and provide a limitless amount of free
energy. To recover and transform this energy to a practical
form like electricity or heating the main devices involved are
the solar panels to generate electricity (photovoltaic) and the
solar collectors to produce hot water or hot air. These units
don’t rely on gas or electricity to operate as they are
autonomous. In addition, using residential solar power is non
pollutant and once the necessary components are bought, you can
have free energy.
The most commonly used residential solar power applications
are thermal. Such technology utilizes the heat coming from the
sun for heating spaces and water. It can also be used for
cooling spaces, ventilation, Desalination, cooking and many
other purposes.
Solar energy is also used to generate
electricity. A good example is the calculator with a small
solar cell. Solar battery chargers are also available;
they can recharge cell phones, Ipods, laptop computers and
other small devices. Space technology is using solar
technology since a long time. Solar panels known also as
photovoltaic, transforms the sun’s energy to electricity.
Residential solar power is also used to provide
electricity for homes. In this particular case, solar
panels are installed on the roof or on the ground. The
electricity produced feeds a battery bank and an inverter
provides 110 or 220 volts for the home. Other popular
solar devices using solar technology are solar lights,
solar fountains and solar pumps. These products are widely
available and are a good example on how solar energy can
be implemented.
Another widely used residential
solar power application is the solar water heater. Solar water
heating is not a new technology and implementation is
straightforward. The system is made of solar collectors that
heat the water when it circulates through tubes. Once heated
the water flows into a storage tank and is available for use.
The same system can be used for heating spaces. Solar
collectors are also used to produce distilled water in this
case the water is obtain by evaporation.
Although not considered as residential solar power, a less
known application of solar energy uses what is called focusing
collectors. The system consists of a movable mirror always
following the sun. Heliostats as they are also called can
generate extremely high temperature. Such systems are usually
used for a solar furnace. Heliostats can also generate
electricity by turning water to steam. The steam obtained can
then run a generator.
All these different devices are allowing transforming the
solar energy into useful and practical applications and solar
power can be obtained using the above different ways. But most
importantly, by using residential solar power technology and
other clean sources of energy you are helping in improving the
environment.
