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.

What is solar PV & how does it work?

Solar PV devices were realized based on the discovery of the PV effect in the 19th century, but momentum has slowed over the past 70 years. Compared with other energy sources, solar PV energy systems do not require moving parts and silently produces clean energy free of GHG emissions with minimal maintenance.

How much sun should a PV module be exposed to?

For maxi-mum daily power output, PV modules should be exposed to the sun for as much of the day as possible, especially during the peak sun hours of 10 a.m. to 3 p.m. Second, the southern exposure must be free of obstructions such as trees, moun-tains, and buildings that might shade the modules.

What is a PV module?

The module is the smallest PV unit that can be used to generate sub-stantial amounts of PV power. 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.

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.

What is PV material?

PV material is deposited on glass or thin metal that mechanically sup-ports the cell or module. Thin-film-based modules are produced in sheets that are sized for speci-fied electrical outputs.
