CdTe solar cells are made by using p–n heterojunctions containing a p-doped Cadmium Telluride layer and an n-doped Cadmium Sulfide (CdS) layer, which may also be made out of magnesium zinc oxide (MZO). While these materials are cheap, they can also be toxic and pollutant when.

Choosing components that work well together enhances the efficiency of a two-panel solar system. The crucial components include the solar panels themselves, a charge controller, batteries (if energy storage is necessary), an inverter (for AC conversion), and wiring.

Monocrystalline panels begin with a pure silicon seed crystal grown using the Czochralski method. The ingot is then sliced into thin wafers and treated with anti-reflective coatings and metal.
