Interesting facts about SOLAR ENERGY

What is solar energy?

As the name suggests, solar energy is one of the primary sources of renewable energy that is obtained through the accumulation of sunlight received by the earth. By utilizing sunlight, solar power can be formed to provide electricity for industries and households, run vehicles, produce scalding water, etc. 

It is an imperishable form of energy and is more feasible than fossil fuels. One of its noticeable advantages is that it is friendly to the environment and does not produce pollution. Therefore, in order to curb pollution and global warming, people are shifting focus towards energy resources found in abundance with solar energy being the most desired one.

What is a solar panel?

The solar panel is a photovoltaic module that traps rays emitted by the sun and converts them into electricity. Through solar panels, light can be transformed into electricity to serve human needs and desires. Once installed, a solar panel can run for approximately 30 years and fulfill all the needs and requirements of the human race.
