Solar Energy Systems: How They Work. 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 Southwest Florida for hundreds of years. Comfort Zone 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. So how does this system work? In a sentence: the system uses solar modules, made up of photovoltaic (PV) cells, to collect 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 computer. Grid-tied PV systems If you live in Cape Coral, you’ll probably want a grid-tied PV system. These are the least costly solar energy systems, and they’re linked 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. Grid-tied systems also let your system feed additional energy back into the grid, causing your meter to spin backwards. We call this process net-metering. The backward spin allows you to 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 second option is a stand-alone PV system, which is more expensive. Stand-alone systems are not linked 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.
