This panel actually has two types which are the crystalline (brown) and amorphous (black) panels. Basically made up of silicons, these panels differ in color, design and production.

The crystalline panel is commonly used among the two. It is made up silicon wafers which are finely sliced silicons that are cut, polished and layered with dopant (an element added to alter the electrical property of a crystal). The silicon wafers are then lined up in a backing panel and secured by conductive metal strips.  It is then layered with clear glass to seal the panel.
Another type is the amorphous panel which is a very thin layer of silicon atoms and dopants sprayed into a glass, metal or plastic backing material. It can be used as flexible panels and solar roof tiles. Amorphous panels are also thinner than the crystalline ones.

Solar panels come in various shapes, sizes and even color but it works in different ways depending on its uses. Water heating solar panels are thermal collectors that have a dark coating absorber plate to convert light to heat. This panel is connected to the water supply where the water basically circulates within it and a storage tank to produce hot water. Photovoltaic panels or PV panels turns light to electricity.

When the sun’s ray hits the panel, it is absorbed by the silicon which acts as a semiconductor. The electrons break free from its atoms allowing it to pass through, bounce within the silicon and dopants thus creating electricity in the form of a direct current (DC). This direct current, which is known as energy stored in batteries, will pass through an inverter that would convert it to an alternating current (AC). This AC would be the electricity we need to run our lights and appliances. GP
