Definition: Solar panels are those devices that are used to
absorb the sun's rays and convert them into electricity or heat.
Description: A solar panel is actually a collection of solar
(or photovoltaic) cells, which can be used to generate electricity through the photovoltaic effect. These cells are arranged in a grid-like pattern on the
surface of solar panels.
Thus, it may also be described as a set of photovoltaic modules, mounted on a structure supporting it. A photovoltaic (PV) module is a
packaged and connected assembly of 6×10 solar cells.
When it comes to wear-and-tear, these panels are very hardy.
Solar panels wear out extremely slow. In a year, their effectiveness decreases
only about one to two percent (at times, even lesser).
Most solar panels are made up using crystalline silicon
solar cells.
Installation of solar panels in homes helps in combating the harmful emissions of greenhouse gases and thus helps reduce global warming.
Solar panels do not lead to any form of pollution and are clean. They also
decrease our reliance on fossil fuels (which are limited) and traditional power
sources.
These days, solar panels are used in wide-ranging electronic
equipment like calculators, which work as long as sunlight is available.
However, the only major drawback of solar panels is that they are quite costly. Also, solar panels are installed outdoors as they need sunlight to get charged.
