Solar power:
Solar power is
energy from the sun and without its existence all life on earth would end.
Solar energy has been seemed upon as a serious source of energy for many years
because of the vast amount of energy that is made easily available.
Solar energy innovation,
quite simply, is power that comes from the sun. But there are now many kinds of
solar energy technological innovation targeted on making use of that energy and
switching it into useful electricity or heat.
Different
types of Energy Technologies in Existence today?
Photovoltaic (PV) panels
Solar power
Photovoltaic panels, is a technology in which sunlight is turned into electric
energy. Solar power Photovoltaic uses
energy from the sun to create electricity that will operate electric equipment
and lighting.
Thin-Film Photovoltaic
Photovoltaic are
of a) lighter in weight, b) less of the expensive silicon material required,
and c) other types of photovoltaic material (amorphous silicon) can be used.
Concentrated Photovoltaic (CPV)
The Concentrated
Photovoltaic advantage over these other systems involves a smaller impact
because the residential solar panels are made of multi-junction residential
solar panels with multi-focusing solar cells, with concentrating rather than
flat silicon cells.
Installing Solar PV
Solar PV panels,
a clear, continuous and unshaded area of ceiling is required, with southern or
near south orientation. The ceiling needs to be large enough to provide the
Solar PV modules, structurally sound and built using materials that are
suitable with a fixing system that is easily obtainable.
Advantages
& Disadvantages of solar energy
• It
is free and numerous energy provided by nature itself
• These
are environmental friendly – as an alternative green source of power.
• Solar
panels (photovoltaic PV panels) can be easily placed in areas.
Disadvantages
• The
cost of solar energy system is high compared to conventional alternatives.
• Solar
energy is directly dependent on weather condition in rain, clouds is considered
highly stable.
