Solar Panels

Photovoltaic PV (solar panels) absorb sunlight as a source of energy to generate direct current electricity. A photovoltaic(PV) module is a packaged, connected assembly of photovoltaic solar cells available in different voltages and wattages. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications.

The most common application of solar energy collection outside agriculture is solar water heating systems.
