How a Solar Energy System Works. If you want a more eco-friendly home, a natural step is to install a solar energy system. After all, the sun’s energy has been cleanly shining down on us in Lafayette County for millions of years. Franklin's Heating & Air Conditioning, Inc. sells the Lennox® SunSource® Energy System to help you create a greener, less oil- and gas-dependent home. So how does this system work? The system uses solar modules, made up of photovoltaic (PV) cells, to harvest energy from the sun and convert it to electricity. Then, the electricity will power appliances, lights and other electrical devices in your home – from your HVAC systems to your phone charger. Grid-tied PV systems If you’re located in or around Oxford, you’re likely going to want a grid-tied PV system. These are the most affordable solar energy systems, and they’re linked to your utility company’s power grid – hence the name grid-tied. This enables 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. Additionally, grid-tied systems enable your system to feed additional energy back into the grid, which will make your meter spin backwards. This process is called net-metering. The backward spin lets you save on utility expenses that are determined by how far forward your meter has spun. It’s important to note that most solar rebates and incentives are only available if your system is grid-tied. The other option is a stand-alone PV system, which costs more. Stand-alone systems are not tied to the utility grid and are fine options when your home is in a remote location, far away from a utility service or power lines.
