How many volts does a PV module produce?

Cell: The basic photovoltaic device that is the building block for PV modules. All modules contain cells. Some cells are round or square, while thin film PV modules may have long narrow cells. Cells are too small to do much work. They only produce about 1/2 volt, and we usually need to charge 12 volt batteries or run motors.

How do you ground mount a PV system?

Two common methods of ground mounting PV systems are racks and poles. Some pole mounts may also have the ability to track the sun across the sky. Another method of ground-mounting is a patio cover. This provides shade to the patio area without taking up valuable yard space. It also provides an alternative to roof mounting.

How does light penetrate a PV cell?

This picture looks at a cross-section of a PV cell. Light actually penetrates into the cell, it doesn’t just bounce off the surface. Particles of light called “photons” bounce into negatively charged electrons around the silicon atoms of the cell, and knock these electrons free from their silicon atoms.
