The document discusses various solar energy technologies including photovoltaics, solar water heaters, and solar heated swimming pools. Photovoltaic panels can generate electricity from sunlight, while solar water heaters and solar pool heating systems use the sun's energy to directly heat water. These solar technologies reduce emissions by using renewable solar energy instead of fossil fuels and help lower electricity bills and other energy costs.

2. Benefits

Energy from the sun can be used
for many practical purposes,
including generating electricity
and heating water.
In fact, using solar energy instead
of fossil fuels to meet some of our
energy needs reduces emissions of
greenhouse gases and other
pollutants

4. Solar Energy
Technologies
 Photovoltaic
 Many residential and
commercial consumers
have chosen to install PV
panels on the roofs of
their homes and
buildings, generating
electricity for their own
use. On average, each kW
of installed PV capacity
can generate 150 kWh of
electricity each month1.

5. Photovoltaic

 These PV panels are the same technology installed
on the roofs of homes and businesses, but electricity
providers connect many cells to form large "arrays"
of photovoltaics with greater capacity to produce
electricity.

7. Solar Water Heater
 Solar water heaters harness
the sun's energy and use it
directly for heating water.
 The solar energy reduces
the need for electricity and
other energy sources
traditionally used for this
purpose.
 Heating water is very
energy intensive – about 25
percent of an average
household's electricity
consumption is devoted to
this purpose2.

9. Solar Heated Swimming
Pools

 The pool's filtration system pumps water from the
pool through pipes in the solar collection panels,
heating the water before its return to the pool.
 The solar heated swimming pool option in the
environmental benefits, please remember that the
resulting emission savings are only estimates, which
are based upon regional climatic conditions.

10. Solar Heated Swimming
Pools

 Many factors will affect the actual energy savings
realized at your pool, including the intensity of solar
radiation, weather conditions, and length of your
swimming season.
 Adding a swimming pool cover will further enhance
the temperature of a swimming pool, and should be
considered along with the solar pool-heating system
to prevent loss of heat to the atmosphere.
