What if your rooftop solar could heat your building in February?
Turn solar from summer waste to winter value
On-site clean energy all year using our thermal battery
Commercial buildings in Europe emit over 250 Mt CO₂ annually from heating — and there are 5 million of them.
Re:notch Solarity Living® helps manufacturing, distribution, and warehouse buildings run cleaner, cheaper, and smarter — using our patented onsite seasonal thermal battery to maximize and store rooftop solar energy.
How It Works: From Solar Peak to Seasonal Heat - A Fully Optimised Energy Loop
Collect: Prioritize between on-site demand, VRE generation, grid value, and midday solar peaks
Store: Target the right zone and temp to maximize usable energy for seasonal heating and cooling.
Generate: Feed the network with optimal temps. Capture and reuse thermal surplus.
Value: Maximize revenue and security. Keep energy storage tuned to seasonal demand.
From Solar Peak to Winter Heat:
Solarity Living® balances solar, grid, and thermal flows for full-season on-site electricity, heating and cooling.
Why Re:notch?
Only seasonal storage that moves cheap summer solar peaks to winter heat use
90% CO₂ reduction vs. conventional heating
ROI in under 10 years — no fossil fuels, no grid strain
