How a Solar Energy System Works. If you want a more environmentally friendly home, a “green” step is to install a solar energy system. After all, the sun’s energy has been shining down on us in East Hanover for thousands of years. Effective Service Group, LLC. offers the Lennox® SunSource® Energy System to help you create a greener, less oil- and gas-dependent home. So how does this system work? The system uses solar modules, made up of photovoltaic (PV) cells, to harvest energy from the sun and convert it to electricity. Then, the electricity can power appliances, lights and other electrical devices in your home – from your HVAC systems to your computer. Grid-tied PV systems If you live in East Hanover, you’ll probably want a grid-tied PV system. These are the least expensive solar energy systems, and they’re tied 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 night, or when the system isn’t gathering energy. In addition, grid-tied systems allow your system to feed surplus energy back into the grid, which will make your meter spin backwards. We call this process net-metering. The backward spin lets you save on utility expenses that are decided based on how far forward your meter has spun. You should note that most solar rebates and incentives are only available if your system is grid-tied. The second option is a stand-alone PV system, which costs more. Stand-alone systems are not linked to the utility grid and are nice options when your home is in a remote location, or too far a distance from a utility service or power lines.
