If you're considering alternative energy sources, one of the most workable methods available is solar. A photovoltaic system is a method of converting solar energy into usable electricity. Unlike the term “solar array,” which refers specifically to the solar panels, the photovoltaic system encompasses all the visible and hidden equipment necessary to utilize sunlight as an energy source.

What It Is

To qualify as a photovoltaic system, the device must convert sunlight directly to electricity. This differs from concentrated solar power, which uses mirrors to gather energy from a large area to power a heat engine. It should also not be confused with solar thermal energy, which is used to heat water or air for use in residences, businesses, and swimming pools.

Basic Setup

A photovoltaic system has several key components. In addition to solar panels, the system includes: the mounting equipment that keeps the panels and other devices in place, the cables that transport the energy, and a solar inverter that converts the current to AC. The system can be mounted on an existing building or integrated into the architecture, and it can stand alone or be connected to the electrical grid.

Additional Components

There are several optional components which can make a photovoltaic system more effective. For example, a solar tracking system helps the array make the most effective use of available sunlight by aiming the panels at the sun over the course of the day. Many systems also incorporate battery storage, since peak energy usage tends not to occur during the hours of the day when production is at its greatest.

A photovoltaic system is an effective and convenient source of renewable energy in many climates and locales. If you're considering going green, this solar power solution is a great step.
