How a Solar Energy System Works. The sun is already giving off huge amounts of energy. Why not put it to work in your own home? With the Lennox® SunSource® Energy System we offer at ACS Inc in Metro Atlanta, you can limit your dependence on oil and gas and see lower utility bills. But how does it change from sunlight to energy? The simplest way to explain a solar energy system is that the system uses solar modules, which are made up of photovoltaic (PV) cells, to collect energy from the sun and convert it to electricity. This electricity will then power 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 carry is grid-tied, and that means it’s connected to your utility company’s power grid or power stations. Grid-tied lets you use your solar energy system to power your home. At times when the system isn’t generating electricity, your home will be able to use power through the utility grid. And, when your system produces an excess amount of electricity, it will be fed back into the grid through a process called 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 another option for those in remote areas without utility service, but they cost a lot more. A stand-alone system is not tied to a utility grid and provide for all of a home’s energy needs. Ready to go solar? Call ACS Inc at 770-939-7500 or schedule a meeting online.
