Solar Energy Systems: How They Work. If you want a more environmentally friendly home, one step is to install a solar energy system. After all, the sun’s energy has been provided to us in Olathe for thousands of years. Polestar Plumbing, Heating & Air Conditioning carries 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? 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 TV. Grid-tied PV systems If you’re in Olathe, you’ll probably 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 enables you to 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. Additionally, grid-tied systems let your system feed additional energy back into the grid, at which time your meter will spin backwards. This is the process of net-metering. The backward spin allows you to save on utility expenses that are decided based on how far forward your meter has spun. Please 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 costly. Stand-alone systems are not linked to the utility grid and are nice options when your home is in a remote location, not near a utility service or power lines.
