Technical FAQs 4

Can a solar energy system run from the grid?

A grid-tied solar energy system allows electricity to run both to and from the power grid. However, it does not operate independently from the grid. In areas with net metering, you can earn electric bill credits by sending excess electricity to the grid.

How do solar inverters work?

Solar inverters transfer the converted AC energy to your home's electrical panel. From there, electricity is dispersed through your house to all of your outlets so that when your devices are plugged in, a usable electric current is available. If you have a grid-tied solar energy system, electricity can run both to and from the power grid.

How do solar panels generate usable electricity?

Solar arrays create a usable electricity system for your home by producing direct current (DC) electricity. This is achieved through the photovoltaic effect, where solar cells convert sunlight into electrical energy.

How do solar photovoltaic cells work?

Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. Source: National Renewable Energy Laboratory (copyrighted)
