Solar Energy Systems: How They Work. 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 have available at True Temp Heating & Air Inc in Chatsworth, you can limit your dependence on oil and gas and lower your utility bills. So how exactly does it work? The easiest way to explain a solar energy system is that the system uses solar modules, which are composed of photovoltaic (PV) cells, to take in 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 have available is grid-tied, meaning 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. On occasions when the system isn’t creating electricity, your home will receive power through the utility grid. And, 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 SunSource System’s electricity is going back into the grid. *Note: Most rebates and incentives that make a solar energy system more affordable 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 linked to a utility grid and provide for the entirety of a home’s energy consumption needs. Ready to go solar?
