How a Solar Energy System Works. The sun is already expelling incredible amounts of energy, which is exactly why you should put it to use in your home. With the Lennox® SunSource® Energy System we carry at Redhawk Heating & Air Conditioning in Odessa, you can limit 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 will then power light, appliances and electrical devices in your home. Grid-tied PV systems Grid-tied PV systems are the most common and least expensive for residential solar systems. The SunSource Energy System we offer is grid-tied, meaning 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. On occasions when the system isn’t producing 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 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 another option for those in remote areas without utility service, but they cost a lot more. A stand-alone system is not connected to a utility grid and provide for all of a home’s energy needs. Ready to go solar?
