Why is Commercial Solar Panel Installation Done? Commercial solar panels are a group of photovoltaic (PV) solar panels that turn sunlight into electricity. Silicon solar cells are what make up photovoltaic (PV) solar panels. Each cell has a layer that is positive and a layer that is negative. These layers work together to make an electric field. A solar panel is made up of many cells, and when several panels or modules are wired together, they form a solar array. In a commercial solar installation, a lot of solar arrays are used to make more electricity. Visit:: https://soflasolar.com/
