PHOTOVOLTAIC SYSTEMS

A photovoltaic (PV) system is composed of one or more solar panels combined with an inverter and other electrical and mechanical hardware that use energy from the Sun to generate electricity. PV systems can vary greatly in size from a small rooftop or portable systems to massive utility-scale generation plants. 

Solar panels and photovoltaic systems are synonymous. If several solar cells are electrically connected with each other within a supporting structure, a photovoltaic module is made.

You can connect solar cells in two different ways: series and parallel.

This way, PV modules can be made at different voltages for different
