What is a PV system?
A PV system consists of all the equipment and materials needed to generate solar energy, including solar
panels (often called modules), a support structure, wiring, an inverter, a meter and other equipment as
required by a specific application. JUST-SOLAR's PV system for commercial buildings, and ET Solar
system for residential uses are examples of complete PV systems.
What is a solar module?
Solar modules are series of solar cells, wired together and enclosed protect them from the environment.
They are often referred to as in self-contained glass units to solar panels as well.
FAQ
