Re:notch – Solar Heating on the Rocks

What if your rooftop solar could heat your building in February? At Re:notch Energy, we help manufacturers, logistics centers, and warehouses run cleaner, cheaper, and smarter—using our patented on-site seasonal thermal battery. Our system captures surplus rooftop solar in summer, stores it in the ground, and delivers reliable heating and cooling all year. This turns cheap, midday solar peaks into clean, winter heat—cutting emissions, costs, and fossil fuel & grid electricity reliance. Why it matters: * Commercial buildings in Europe emit over 250 Mt of CO₂ from heating every year—and there are more than 5 million of them. * Rooftop solar is the lowest-cost energy available—but most of it goes unused when it’s needed most: winter. * Heat pumps alone aren’t enough. Without long-duration storage, solar potential is wasted and grid bottlenecks worsen. Our innovation, Solarity Living®, moves energy through seasons. With SunRock® thermal storage beneath your site, we: * Cut Scope 1 & 2 CO₂ by up to 90% * 30% reduction of heating and cooling bills * Achieve ROI <10 years, IRR >15%, and LCCA of –150 €/ton CO₂ * Deliver 75% energy cost predictability for 30 years * Boost property value and enable green leasing Built for a grid-constrained world with cheap solar peaks, Re:notch enables behind-the-meter energy that avoids levies, curtailment, and volatility—while unlocking financing and resilience for commercial buildings. If you want your building to use solar—even in winter—let’s connect.
