Solar panels

Solar cells, also known as "solar chips" or "photovoltaic cells," are thin optoelectronic semiconductor wafers that use sunlight to directly generate electricity. Single solar cells cannot be directly used as power sources. As a power source, several individual solar cells must be connected in series or parallel and tightly packaged into components.
Solar panels (also known as solar cell modules) are assemblies of multiple solar cells, which are the core and most important part of a solar power generation system.
