Solar Energy Systems: How They Work. If you want a more environmentally friendly home, a natural step is to purchase a solar energy system. After all, the sun’s energy has been shining down on us in El Paso County for thousands of years. Mitchell Heating offers the Lennox® SunSource® Energy System to help you create a more efficient home that doesn’t heavily rely on oil and gas. So how does this system work? The system uses solar modules, made up of photovoltaic (PV) cells, to collect energy from the sun and convert it to electricity. Afterwards, the electricity can 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 in Colorado Springs, you’ll probably 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 times when the system isn’t gathering energy. In addition, grid-tied systems allow your system to feed surplus energy back into the grid, which will make your meter spin backwards. We call this process net-metering. The backward spin allows you to save on utility expenses that are totaled by how far forward your meter has spun. You should 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 good options when your home is in a remote location, not near a utility service or power lines.
