is a device that absorbs solar radations and converts it into electricity or heat. Most solar panels are made up using crystalline silicon solar cells.
Solar panel is actually a collection of solar cells, which are used to generate electricity through photovoltaic effect. These cells are arranged in a grid-like pattern on the surface of solar panels.
When it comes to wear-and-tear, these panels are very hard because most of them have a lifespan of 25 years. Solar panels wear out extremely slow. In a year, their effectiveness decreases only about 1% to 2% at times.
These days, solar panels are used in wide-ranging electronic equipment like calculators, which work as long as sunlight is available, Because this helps in combating the harmful emissions of greenhouse gases and thus helps reduce the global warming.
