Photovoltaic panels with integrated heating
A photovoltaic thermal (PVT) system combines photovoltaic panels with a thermal collector to produce both electricity and heat from the same surface. It produces 6-8 times more energy than a standard PV panel, maximizing energy output while minimizing your carbon footprint. SPRING works with every type of system:. One of the most effective pairings is integrating air-to-water heat pumps with solar panels. Unlike conventional solar panels that only generate electricity, PVT systems combine photovoltaic and thermal technologies to simultaneously produce both. Field measurements show that solar-thermal integration can reduce grid electricity consumption by 40-60%, but system performance varies significantly with solar insolation levels, ambient temperatures, and dynamic cooling loads. Current installations must manage the mismatch between peak solar. New research from Germany's Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has shown that combining rooftop PV systems with battery storage and heat pumps can improve heat pump efficiency while reducing reliance on grid electricity.

Home heating and cooling energy storage system
Thermal Energy Storage (TES) is an energy storage method that can help balance energy demand and supply daily, weekly, and even seasonally. TES refers to heating or cooling a medium to use the energy when required later. The most common application of TES systems is integration with solar systems. Home energy storage systems are designed to capture and store electricity—typically generated from renewable sources like solar panels—for later use. Unlike relying solely on the grid, these systems let you: Reduce energy bills: Use stored solar energy during peak hours when grid electricity rates. Thermal energy storage can be accomplished by changing the temperature or phase of a medium to store energy.
