How a Solar Energy System Works. If you want a more eco-friendly home, a natural step is to install a solar energy system. After all, the sun’s energy has been provided to us in Hauppauge for hundreds of years. Cool Power LLC offers 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? 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 will power appliances, lights and other electrical devices in your home – from your HVAC systems to your phone charger. Grid-tied PV systems If you live in Hauppauge, you will want a grid-tied PV system. These are the least costly 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 when the system isn’t gathering energy. Additionally, grid-tied systems let your system feed additional 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 totaled by 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 second option is a stand-alone PV system, which is more expensive. Stand-alone systems are not tied to the utility grid and are fine options when your home is in a remote location, or too far a distance from a utility service or power lines.
