Solar Energy Systems: How They Work. If you want a more environmentally responsible home, a natural step is to purchase a solar energy system. After all, the sun’s energy has been shining down on us in Pinellas County for hundreds of years. Hale's Air Conditioning Services Inc offers the Lennox® SunSource® Energy System to help you create a home that relies more on natural energy and less on oil and gas. Just how does this system work? In a sentence: the system uses solar modules, made up of photovoltaic (PV) cells, to take in 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 located in or around Pinellas County, you’re likely going to want a grid-tied PV system. These are the least expensive solar energy systems, and they’re tied 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. Additionally, grid-tied systems let your system feed extra energy back into the grid, causing your meter to spin backwards. This process is called net-metering. The backward spin allows you to 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 fine options when your home is in a remote location, not near a utility service or power lines.
