What are the components of a PV system?

In addition to PV mod-ules, the components needed to complete a PV system may include a battery charge controller, batteries, an inverter or power control unit (for alternating-current loads), safety disconnects and fuses, a grounding circuit, and wiring. (See 36 cells.

What is a single PV cell?

Single PV cells (also known as “solar cells”) are connected electrically to form PV modules, which are the building blocks of PV systems. The module is the smallest PV unit that can be used to generate sub-stantial amounts of PV power.

Should you consider a photovoltaic (PV) system?

If you are thinking of generating your own electricity, you should consider a photovoltaic (PV) system—a way to gen-erate electricity by using energy from the sun.

How do PV modules work?

The modules can be connected into PV arrays for powering a wide variety of electrical equipment. Two primary types of PV technologies available commercially are crystalline sili-con and thin film. In crystalline-silicon technologies, individual PV cells are cut from large single crystals or from ingots of crystalline silicon.

Why do PV systems need a battery?

Battery. The battery stores electricity for use at night or for meeting loads during the day when the modules are not gener-ating sufficient power to meet load requirements. To provide electricity over long periods, PV systems require deep-cycle batteries.

How much electricity does a PV module produce?

Although individual PV cells produce only small amounts of electricity, PV modules are manufactured with varying electrical out-puts ranging from a few watts to more than 100 watts of direct current (DC) elec-tricity. The modules can be connected into PV arrays for powering a wide variety of electrical equipment.
