PV Gap

Lonnie Said:

how solar cell are made and connected to penal?

We Answered:

The cells are connected together to make a panel. Depending what the cells outputs are, and what voltage you need for an output, you wire them as you would battereis, so most likely you would have a combination of serially wired cells wired in parallel to compose your full panel. Wired in series increases voltage, current is limited to the smallst cell's output. Wired in parallel, you get the same voltage as a single cell, but current adds up.

Each company handles the combinations differently, and the back plane ,materials will vary as the manufacturers needs require them.

Questions about Solar Cells.?

We Answered:

There are two basic types. Thermal and photovoltaic.

A thermal solar cell typically heats liquid that is used to heat or to power a turbine. Think of it like a garden hose in the summer. When you first turn it on the water it can be really hot.

Photovoltaic solar cells generate electricity directly. They can do this because the photons in sunlight are strong enough to knock electrons out of the atoms of the solar cells surface. This potential energy is collected to form an electric circuit.
