big note on solar pannel
Answers
Answer:
Solar panels are those devices which are used to absorb the sun's rays and convert them into electricity or heat.
A solar panel is actually a collection of solar (or photovoltaic) cells, which can be used to generate electricity through 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 per cent (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 equipments 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
Definition:
Solar panels are those devices which are used to absorb the sun's rays and convert them into electricity or heat. A solar panel is actually a collection of solar (or photovoltaic) cells, which can be used to generate electricity through photovoltaic effect. A solar cell is a device which converts solar energy directly into electricity. A group of solar cells is called a solar cell panel. It consists of a large number of solar cells joined together in a definite pattern.
Main unit of the solar panel:
A solar cell is the smallest unit of a solar power system. Many solar cells make a solar panel. A solar cell is the basic electricity generating unit of the solar photovoltaic system.
Biggest size of Solar Panel:
As of March 5, 2019, the highest wattage solar panel available is the SunPower 415 watt residential solar panel. Boasting a ground-breaking 22.3% efficiency, the SunPower 415 is the highest efficiency solar panel commercially available.
Uses of Solar Panels:
1. Solar panels are used to generate electricity either domestic purpose or industrial purpose.
2. Solar panels produce electricity in remote locations.
Advantage of Solar Panel:
Solar power is a 100% clean, renewable energy source. It reduces reliance on oil, coal and natural gas for electricity production. These fossil fuels produce harmful emissions that affect the quality of air, water and soil, and are responsible for global warming.
