What is solar surplus?
It is the power left after instant loads and, where applicable, battery charging. It changes continuously and should be measured in real time.
A sensible priority order
Cover building loads first, then the battery reserve, hot water or buffer tank, EV charging and flexible processes. Export what remains.
- Direct building loads
- Battery target reserve
- Heat and mobility
- Residual export
Battery or heat?
A battery is flexible but limited by capacity and cycles. Thermal storage can absorb lower-cost energy when there is genuine later heat demand.
When mining heat fits
Water-cooled computing can supply useful heat, but requires hydraulics, temperature limits, safety, summer heat rejection and economics without promises.
Conclusion
A measurable priority strategy turns surplus into value. Voltalps assesses loads, storage and heat demand as one system.
