How a Solar Energy System Works. If you want a more environmentally friendly home, one step is to purchase a solar energy system. After all, the sun’s energy has been provided to us in Kansas City for hundreds of years. Air Unlimited Heating & Cooling offers the Lennox® SunSource® Energy System to help you create a greener, less oil- and gas-dependent home. Just how does this system work? In a sentence: the system uses solar modules, made up of photovoltaic (PV) cells, to harvest 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 phone charger. Grid-tied PV systems If you’re in Liberty, you will 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 allows 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 enable your system to feed extra energy back into the grid, which will make your meter spin backwards. We call this process net-metering. The backward spin lets you save on utility expenses that are totaled 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. Another option is a stand-alone PV system, which costs more. Stand-alone systems are not connected to the utility grid and are nice options when your home is in a remote location, not near a utility service or power lines.
