What is a Solar Panel: Your Guide to Capturing Sun's Energy

A solar panel is a device that converts sunlight into electricity. The electricity can be used to power homes, businesses, and other buildings, or it can be sold back to the grid. Solar panels are made up of photovoltaic cells, which are semiconductor devices that absorb sunlight and create an electrical current.

Solar panels are becoming increasingly popular as a source of renewable energy. They are environmentally friendly, do not produce greenhouse gases, and can help to reduce our dependence on fossil fuels. Solar panels are also becoming more affordable, making them a more viable option for many people.
The first solar panel was invented in 1883 by Charles Fritts. However, it was not until the 1950s that solar panels became efficient enough to be used for practical applications. Today, solar panels are used in a wide variety of applications, including:

Residential homes
Commercial buildings
Industrial facilities
Remote power systems
Space satellites

Solar panels are an important part of the fight against climate change. They are a clean, renewable source of energy that can help us to reduce our reliance on fossil fuels. As solar panels become more affordable and efficient, they will play an increasingly important role in our energy future.
