What is Solar Panel, and Why is commercial solar installation is done?

Commercial solar panels are a group of photovoltaic (PV) solar panels that convert sunlight into electricity. Photovoltaic (PV) solar panels are made up of solar cells made of silicon. Each cell has a positive layer and a negative layer that work together to create an electric field. A solar panel is made up of many cells, and when several panels or modules are wired together, they make a solar array. To make more electricity, a commercial solar installation is done to use a lot of solar arrays.
