FAQ

Solar Chillers — frequently asked

How is a solar chiller sized?

Start from the peak cooling duty (kW), then match PV kWp to daily kWh demand ÷ peak sun hours × 1.3 derating. A 100 kW DC-inverter chiller in a hot climate typically pairs with 120–180 kWp of PV and 200–400 kWh of BESS, or 4–8 hours of chilled-water TES for battery-free operation.

PV + electric chiller vs absorption chiller — which wins?

For most industrial and cold-chain sites, PV + DC-inverter electric chillers beat absorption on CAPEX and LCOE. Absorption wins only when free waste heat above 90 °C or concentrated solar-thermal is already available.

Can a solar chiller run 24/7?

Yes — with either lithium BESS (typical 4–8 h autonomy) or chilled-water / ice thermal storage. Hybrid PV + grid + genset controllers ensure zero downtime for critical process loads.

How does ColdMatch source solar chillers?

We brief 3–5 audited chiller OEMs and solar EPC integrators with a structured spec (duty, temperature, autonomy, refrigerant, hybrid strategy) and benchmark quotes on CAPEX, LCOE and 20-year OPEX.
