How a Solar Energy System Works. If you want a more environmentally friendly home, one step is to add a solar energy system. After all, the sun’s energy has been provided to us in Valencia for hundreds of years. Payless Heating & Air Inc carries the Lennox® SunSource® Energy System to help you create a more efficient home that doesn’t heavily rely on oil and gas. So how does this system work? Put simply, the system uses solar modules, made up of photovoltaic (PV) cells, to harvest energy from the sun and convert it to electricity. After this process, the electricity will power appliances, lights and other electrical devices in your home – from your HVAC systems to your computer. Grid-tied PV systems If you’re located in or around Valencia, you will want a grid-tied PV system. These are the most affordable solar energy systems, and they’re linked to your utility company’s power grid – hence the name grid-tied. This enables you to use solar energy from your system when the PVs are collecting energy and use electricity from the grid at times when the system isn’t gathering energy. Grid-tied systems also let your system feed extra energy back into the grid, which will make your meter spin backwards. We call this process net-metering. The backward spin allows you to save on utility expenses that are decided based on how far forward your meter has spun. It’s important to note that most solar rebates and incentives are only available if your system is grid-tied. The other option is a stand-alone PV system, which is more costly. Stand-alone systems are not connected to the utility grid and are good options when your home is in a remote location, far away from a utility service or power lines.
