Solar Energy Systems: How They Work. If you want a more environmentally friendly home, a natural step is to install a solar energy system. After all, the sun’s energy has been provided to us in Box Butte County for millions of years. Jack's Refrigeration Heating and Cooling offers the Lennox® SunSource® Energy System to help you create a home that relies more on natural energy and less on oil and gas. So how does this system work? The system uses solar modules, made up of photovoltaic (PV) cells, to take in 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 live in Alliance, you will want a grid-tied PV system. These are the least expensive solar energy systems, and they’re connected 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. Grid-tied systems also enable your system to feed surplus energy back into the grid, at which time your meter will 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. You should 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 costs more. Stand-alone systems are not connected 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. Jack's Refrigeration Heating and Cooling in Alliance is eager to help with your solar energy system questions. Give us a call at 308-646-3827 or schedule an appointment online.
