PV modules (solar panels) collect the sun’s energy and convert it into electricity using semiconducting material. A module is composed of several solar cells connected in series and in parallel.
PV solar modules are grouped in a solar array, and connected in series or in parallel. By nature, photovoltaic solar power is very modular.
The direct-current (DC) power produced by the PV module cannot be used by the vast majority of household apparatus. The electricity is sent to an inverter that outputs an alternative current (AC) signal.
A PV solar system can be designed to provide the totality of a building’s electricity consumption or a fraction of the building needs.
