Solar energy is the energy that comes from the Sun in the form
of radiant light and heat. It is considered the most widespread
form of renewable energy of the planet. Solar powered electrical
generation relies on heat engines and photovoltaics. Solar
Thermal/Electric Power Plants generate electricity by
concentrating solar energy to heat a fluid and produce steam
that is used to power a generator. A solar cell or photovoltaic
(PV) cell is a device that converts sunlight into electric
current using the photoelectric effect. Individual PV cells are
grouped into solar panels and arrays of panels that can be used
in a wide range of applications. Solar technologies are broadly
characterized as either passive solar or active solar depending
on the way they capture, convert and distribute solar energy.
The use of the sun’s energy for the heating and cooling of
living spaces is called passive solar technology. In this
approach, the building design itself or some element of it takes
advantage of natural energy charact
