Solar refrigeration savings calculator
Estimate annual kWh, USD, diesel and CO₂ savings from adding PV + battery storage to a refrigeration plant. Sizing, CAPEX and payback in one page.

PV kWp = (annual refrigeration kWh × PV share target) ÷ climate-specific yield (1,200 / 1,600 / 1,900 kWh per installed kWp). It assumes a modern grid-tied inverter, 15% system losses and a well-oriented roof or ground-mount.
What CAPEX benchmarks are used?
USD 850/kWp installed for PV (module + inverter + BOS + installation) and USD 350/kWh for LFP battery storage. Adjust with the scenario selector: optimistic (−15%), base, pessimistic (+20%).
Is this enough for a bankable feasibility study?
No — this is an order-of-magnitude study for pre-feasibility, budgeting and lender briefings. For bankable, you need on-site load metering, PVsyst simulation, geotechnical, and detailed grid-code analysis. ColdMatch can run this study through qualified engineering partners.
How is CO₂ avoided calculated?
kWh displaced × 0.45 kg CO₂/kWh (global grid average). Diesel displaced × 2.68 kg CO₂/L. Actual values depend on grid mix — MENA / SSA hybrids typically save 50–80% more per kWh than an EU grid average.
Can PV realistically cover a 24/7 refrigeration load?
60–80% renewable fraction is achievable with a PV+BESS hybrid and grid or diesel backup. Higher fractions (85–95%) need oversized PV plus 12–24 h storage — CAPEX rises sharply. The tool caps PV share at 90% to reflect this.

Your size, cost and load inputs are copied into the quote form, so you don't type them twice. Nothing is sent until you review and submit.
Free for buyers, no obligation. These figures are estimates, not quotes — our team reviews your request and contacts suitable suppliers on your behalf.
≈ 591,300 kWh/yr from PV and a ≈ 690 kWh battery; kWp, savings and payback depend on the selected site yield.
Limitations
• Site yield is a regional average; shading, tilt and soiling need a PV simulation.
• PV share is capped at 90% — refrigeration still needs grid or generator backup at night.
• Tariffs and fuel prices are user inputs; escalation and financing are not modelled.
