Solar Energy Systems: How They Work. If you want a more environmentally responsible home, a “green” step is to purchase a solar energy system. After all, the sun’s energy has been provided to us in Sarasota County for millions of years. Symbiont Service Corp sells the Lennox® SunSource® Energy System to help you create a home that relies more on natural energy and less on oil and gas. Just how does this system work? In a sentence: the system uses solar modules, made up of photovoltaic (PV) cells, to take in energy from the sun and convert it to electricity. After this process, the electricity can be used to power appliances, lights and other electrical devices in your home – from your HVAC systems to your TV. Grid-tied PV systems If you live in Englewood, you’ll probably want a grid-tied PV system. These are the least costly solar energy systems, and they’re linked to your utility company’s power grid – hence the name grid-tied. This allows you to use solar energy from your system when the PVs are collecting energy and use electricity from the grid at night, or when the system isn’t gathering energy. In addition, grid-tied systems allow your system to feed surplus energy back into the grid, at which time your meter will spin backwards. We call this process net-metering. The backward spin lets you save on utility expenses that are determined by how far forward your meter has spun. Please note that most solar rebates and incentives are only available if your system is grid-tied. The second option is a stand-alone PV system, which costs more. Stand-alone systems are not linked to the utility grid and are nice options when your home is in a remote location, not near a utility service or power lines.
