One of the most popular and cost-effective solutions for residential properties that are already connected to their local utility grid: Grid Tie systems feed electricity created by your solar panels directly into your home electricity system and require less equipment to install. This reduces your initial costs and reduces the amount of electricity you purchase from your utility provider. They contribute significant savings to your energy bills each month. Any excess solar created is exported to the grid during the day. At night or during periods of insufficient solar power, the utility grid will seamlessly meet your needs for electricity in the home.
