Problem
Households with solar panels often send excess energy back to the grid, receiving limited compensation and potentially incurring charges. Fluctuating energy prices and changes to net metering policies further complicate energy cost management for homeowners.
Solution
Sessy provides a smart home battery that stores surplus solar energy for later use, reducing reliance on the grid and maximizing self-consumption. The system integrates with existing solar panel setups and offers multiple operating modes, including self-consumption, dynamic pricing optimization, and grid services participation. A user-friendly portal and mobile app provide real-time monitoring and control, while an open API enables integration with home automation systems. Sessy's modular design allows for scalable energy storage, adapting to changing household needs and energy market conditions.
Target Audience
The primary target audience includes homeowners with existing or planned solar panel installations seeking to increase self-sufficiency, reduce energy costs, and participate in grid stabilization programs.
