Solar panels (photovoltaic panels) are semiconductor materials that produce DC (direct current) electrical energy when photons, which are the carriers and spreaders of solar energy, fall on them. Their yield varies between 15% and 20% depending on the type of panel. You can visit the HOMEPROF (Cheaper and More Professional) site for the solar panels.
Different panel types can be listed as follows.
- Mono Crystal Panels
- Poly Crystal Panel
- Thin Film Panels
