Solar cells, also known as photovoltaic cells, convert sunlight directly into electricity, while solar collectors absorb the sun's heat to generate thermal energy. Both technologies are used to capture and utilize solar energy for various applications, such as powering homes, businesses, and other electrical devices. Additionally, both solar cells and solar collectors are part of the broader effort to transition towards renewable energy sources and reduce reliance on fossil fuels. **

It is made up of multiple solar cells that convert sunlight into electricity through the photovoltaic effect. When multiple solar modules are connected together, they form a solar array that can generate significant amounts of electricity for residential, commercial, or industrial use. **
