How a Solar Energy System Works. The sun is already giving off incredible amounts of energy, which is exactly why you should put it to use in your home. With the Lennox® SunSource® Energy System we offer at Craig's Appliance Heating & Cooling in Bountiful, you can decrease your dependence on oil and gas and reduce your utility bills. But how exactly does this happen? The easiest way to explain a solar energy system is that the system uses solar modules, which are composed of photovoltaic (PV) cells, to gather energy from the sun and convert it to electricity. This electricity is used to 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 have available is grid-tied, which 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 creating electricity, the utility grid will supply power to your home. In addition, when your system produces more electricity than you will use, it will be fed back into the grid through net-metering. With net-metering, your meter spins forward if you’re using electricity from the grid and backward when you’re feeding electricity from your SunSource System 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 an alternative for those in remote areas without utility service, however they’re much more expensive. A stand-alone system is not linked to a utility grid and provide for a home’s entire energy consumption. Ready to go solar?
