Solar Energy

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.


             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.
