3 Types of Solar Energy Systems: Which One Is Right for You?

All solar energy systems begin with a series of small photovoltaic (PV) cells that produce electricity directly from sunlight. These PV cells are combined to form a module or panel. Several panels are connected together to form an array or a solar system. Arrays can be small—from a few panels to power a roadside warning sign or a remote cabin—up to a large array covering hundreds of acres as part of a utility-scale solar farm.

Solar systems can generally be divided into three different types of arrays based on size.
