Rooftop solar is undeniably appealing to homeowners. It is a technology that promises to power homes with clean, renewable sunshine AND save money. Solar buyers can save thousands of dollars while doing their part to help reduce greenhouse gases, a win-win-win for utilities, system owners and the environment. However, the limitations of traditional solar and solar + storage have left some system owners in the dark and paying more out of pocket.
Two key issues result in dissatisfaction with traditional solar. First, the time of day when solar is produced doesn’t match up with when homeowners are using the most energy. In this case, system owners can be exposed to high energy costs during peak-rate periods. Second, solar alone cannot power a home during a grid outage, leaving the solar customer vulnerable when the grid goes down. System owners have turned to energy storage to overcome these challenges, but off-the-shelf battery systems are only capable of powering a couple of appliances for a few hours during a power outage. Generac dove into the solar industry in 2019 to solve these problems, the result is the PWRcell Solar + Battery Storage system.
