Solar Energy Systems: How They Work. 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 shining down on us in Peoria for millions of years. Accurate Heating & Cooling LLC offers the Lennox® SunSource® Energy System to help you create a greener, less oil- and gas-dependent home. Just how does this system work? Put simply, the system uses solar modules, made up of photovoltaic (PV) cells, to harvest energy from the sun and convert it to electricity. Afterwards, 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 in Peoria, you will want a grid-tied PV system. These are the least expensive solar energy systems, and they’re linked 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 at times when the system isn’t gathering energy. Additionally, grid-tied systems enable your system to feed extra energy back into the grid, causing your meter to spin backwards. This is the process of net-metering. The backward spin helps you save on utility expenses that are totaled 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 is more expensive. Stand-alone systems are not connected 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.
