How a Solar Energy System Works. The sun is already giving off massive amounts of energy. Why not put it to work in your own home? With the Lennox® SunSource® Energy System we offer at Smyth Air Conditioning Inc in Lake Worth, you can decrease your dependence on oil and gas and reduce your utility bills. So how exactly does it work? The simplest way to explain a solar energy system is that the system uses solar modules made of photovoltaic (PV) cells to take in energy from the sun and convert it to electricity. This electricity powers light, appliances and electrical devices in your home. Grid-tied PV systems Grid-tied PV systems are very common and the most affordable for residential applications. The SunSource Energy System we have available is grid-tied, which means it’s connected to your utility company’s power grid or power stations. Grid-tied enables you to use your solar energy system to power your home. When the system isn’t creating electricity, your home will receive power through the utility grid. And, when your system produces an excess amount of electricity, it will be fed back into the grid through the process of net-metering. With net-metering, your meter spins forward if you’re using electricity from the grid and backward when you’re SunSource System’s electricity is going back into the grid. *Note: Most rebates and incentives that make a solar energy system easier to afford are only available when your system is grid-tied. Stand-alone PV systems are also available for those in remote areas without utility service, but they’re considerably more expensive. A stand-alone system is not connected to a utility grid and provide for the entirety of a home’s energy consumption needs. Ready to go solar?
