Solar energy 4 KW 5KW 8KW photovoltaic panel system for grid tied and off grid system
Photovoltaic cells are usually manufactured from silicon although other materials can also be used. n-type semiconductors are made of crystalline silicon
that has been “doped” with tiny quantities of an impurity (usually phosphorous) in such a way that the doped material possesses a surplus of free electrons. On
the other hand, p-type semiconductors are also made from crystalline silicon, but they are doped with very small amounts of a different impurity (usually boron)
which causes the material to have a deficit of free electrons. Combination of these two dissimilar semiconductors produces an n-p junction, which sets up an electric
field in the region of the junction. Such a set up will cause negatively (positively) charged particles to move in one direction (in the opposite direction).
Light is composed of a steam of tiny energy particles called photons, and if photons of a suitable wavelength fall within the p-n junction, then they can
transfer their energy to some of the electrons in the material so prompting them to a higher energy level. When the p-n junction is formed, some of the electrons in
the immediate vicinity of the junction are attracted from the n-type layer to combine with holes on the nearby p-type layer. Similarly, holes on the p-type layer near
the junction are attracted to combine with electrons on the nearby n-type layer. Hence, the net effect is to set up around the junction a layer on the n-type
semiconductor that has more positive charges than it would otherwise have.
VIII. Advantages and Disadvantages of Solar Energy
ADVANTAGES:
·Solar energy is clean.
·More cheaper than electric heating.
·Solar energy is a great alternative because it provides you with anything from heating water, electricity, and even cooking.
·If you live in a remote area where there are no power-lines solar energy can be the solution.
·Another great use of solar energy is for desalination in areas where fresh, drinkable water is scarce.?
DISADVANTAGES:
·The main disadvantage of solar energy is that it’s dilute.
·One big disadvantage is that you need the sun rays to make use of solar energy.
L·astly the sun only shines during the day.?
