How a Solar Energy System Works. If you want a more environmentally responsible home, one step is to install a solar energy system. After all, the sun’s energy has been provided to us in Wharton for thousands of years. Faust Air Conditioning and Heating carries 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? Put simply, 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 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 live in Wharton, you will want a grid-tied PV system. These are the least costly solar energy systems, and they’re connected 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 night, or when the system isn’t gathering energy. In addition, grid-tied systems enable your system to feed extra 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 decided based on 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 second option is a stand-alone PV system, which costs more. Stand-alone systems are not linked 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.
