1-Monocrystalline solar panels : The most efficient and
expensive solar panels are made with Monocrystalline cells. These solar
cells use very pure silicon and involve a complicated crystal growth
process. Long silicon rods are produced which are cut into slices of .2
to .4 mm thick discs or wafers which are then processed into individual
cells that are wired together in the solar panel. |
2-Polycrystalline solar panels : Often called
Multi-crystalline, solar panels made with Polycrystalline cells are a
little less expensive & slightly less efficient than Monocrystalline
cells because the cells are not grown in single crystals but in a large
block of many crystals. This is what gives them that striking shattered
glass appearance. Like Monocrystalline cells, they are also then sliced
into wafers to produce the individual cells that make up the solar
panel. |
3-Amorphous solar panels : These are not really crystals, but a
thin layer of silicon deposited on a base material such as metal or
glass to create the solar panel. These Amorphous solar panels are much
cheaper, but their energy efficiency is also much less so more square
footage is required to produce the same amount of power as the
Monocrystalline or Polycrystalline type of solar panel. Amorphous solar
panels can even be made into long sheets of roofing material to cover
large areas of a south facing roof surface.
Solar Power has
many advantages:
Advantages:
- Solar Energy is a renewable form of energy and
tends to give us large amount of energy and light. Oil, on the other
hand is not renewable and also degrades the environment.
- Solar cells are very silent in their working
and they are quite efficient too,
- Solar energy equipments do not emit any harmful
gases or radiations. They are highly eco-friendly.
- Solar cells require very less maintenance and
they have a long life too.
- Though, the initial set up of the solar panels
is expensive, later on they turn out to be highly cost effective,
