Solar-only homeowners generate electricity during the day but still depend on the national grid when solar power isn’t available, often paying high rates. Despite this limitation, they can still save hundreds of pounds a year on their energy bills. However, their reliance on the grid leaves them exposed to peak-time costs and outages. In contrast, a virtual power plant (VPP) connects multiple solar-powered homes with battery storage, creating a smarter, more efficient, and resilient energy network.
