Solar Energy Systems: How They Work. The sun is already expelling incredible amounts of energy, so why not put it to use? With the Lennox® SunSource® Energy System we have available at Anderson Heating & A/C in Carson City, you can cut down on your dependence on oil and gas and see lower utility bills. So how exactly does it work? The simplest way to explain a solar energy system is that the system uses solar modules, which are composed of photovoltaic (PV) cells, to collect energy from the sun and convert it to electricity. This electricity powers light, appliances and electrical devices in your home. Grid-tied PV systems This is the most common and least expensive residential solar system. The SunSource Energy System we have available is grid-tied, meaning it’s connected to your utility company’s power grid or power stations. Grid-tied allows you to use your solar energy system to power your home. On occasions when the system isn’t creating electricity, your home will receive power through the utility grid. Additionally, when your system produces enough to power your home and then some, 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 putting your SunSource System’s electricity back into the grid. *Note: Most rebates and incentives that make a solar energy system less costly are only available when your system is grid-tied. Stand-alone PV systems are an alternative for those in remote areas without utility service, but they’re considerably more expensive. 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 Anderson Heating & A/C at 775-882-8154 or schedule an appointment online.
