A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or “hole” is created.

Bonding prevents a host of possible risks and dangers. “Imagine: the insulation on a PV source circuit wire becomes damaged, and the current-carrying part of the conductor makes contact with a frame or rail,” said Brian Mehalic, PV Curriculum Developer and Instructor at Solar Energy International.
Solar panels convert sunlight into electricity. This process involves converting the Direct Current (DC) generated by the solar panels into Alternating Current (AC) using an inverter. The inverter is then connected to an electrical meter, which measures the electricity generated by the solar panel system.
