How a solar power system works.

When solar panels are installed in homes, sunlight falls on these panels, which then convert sunlight into direct current (DC). The current then flows to an inverter, which in turn converts the electricity from DC to alternating current (AC), after which the electricity can be used in homes. Solar panels are simple to install, aesthetically pleasing, and provide high and convenient efficiency for generating electricity most of the time.

But what happens if you're not at home to take advantage of the electricity generated by the solar panels, or when the panels can't generate electricity at night?

Don't worry, you still benefit from electricity through a system called a "net meter," which is a model that connects the photovoltaic system to the general electricity grid. Often, solar panels produce more energy than an individual needs, especially on sunny days. The surplus energy goes to the general grid for use elsewhere, and in return, the individual receives a credit of electricity from the general grid, which can be used when the panels cannot generate electricity at night or on cloudy days. Each time, the net meter records the energy generated by the solar panels and compares it to the energy used from the grid.
