Solar Energy Systems: How They Work. If you want a more environmentally responsible home, one step is to purchase a solar energy system. After all, the sun’s energy has been provided to us in Midlothian for millions of years. Daniel's Heating & Refrigeration Corp. offers the Lennox® SunSource® Energy System to help you create a more efficient home that doesn’t heavily rely on oil and gas. But how does this system work? Put simply, the system uses solar modules, made up of photovoltaic (PV) cells, to collect energy from the sun and convert it to electricity. After this process, the electricity can power appliances, lights and other electrical devices in your home – from your HVAC systems to your TV. Grid-tied PV systems If you’re located in or around Midlothian, you will want a grid-tied PV system. These are the least expensive solar energy systems, and they’re tied to your utility company’s power grid – hence the name grid-tied. This lets you use solar energy from your system when the PVs are collecting energy and use electricity from the grid when the system isn’t gathering energy. In addition, grid-tied systems enable your system to feed extra energy back into the grid, at which time your meter will spin backwards. We call this process net-metering. The backward spin allows you to save on utility expenses that are decided based on 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 second option is a stand-alone PV system, which is more expensive. Stand-alone systems are not linked to the utility grid and are good options when your home is in a remote location, far away from a utility service or power lines.
