Access to France's reduced VAT rate for residential solar installations is dependent on the use of low-carbon panels and a home energy management system, such as PvPilot's software. This platform orchestrates household electrical devices in real time based on solar production and consumption patterns, controlling devices like water heaters, batteries, and electric vehicle charging stations. By visualizing energy data and optimizing AC-coupled batteries, the system aims to increase solar self-consumption and enable fully solar-powered operation without drawing from the grid. This B2B2C model offers a comprehensive solution for maximizing the efficiency and sustainability of residential solar installations.
