ColdMatch Group · Solar Off-Grid Cold Storage Network
Solar off-grid cold storage network — 10-hub engineering, budget & financing
A solar off-grid cold storage network deploys 8–20 modular cold hubs of 50–500 m³ across rural food-producing zones — smallholder aggregation, dairy, horticulture and fish landing sites — powered by PV + BESS or PV + thermal storage. Structured for concessional finance, results-based grants and blended-finance vehicles.
10 rural solar cold hubs, 50–500 m³ each, PV + BESS/TES, blended-finance-ready.
Engineering
- 10 modular hubs × 50–500 m³, chilled (+2/+8 °C) and mixed chilled/frozen configurations
- PV 15–120 kWp per site, BESS 30–250 kWh (LFP) or ice-bank / PCM thermal storage
- R290 (propane) DC-inverter compressors — best fit for variable PV power
- Containerised or panel-built rooms, redeployable, with 5–10 year warranties
- Remote monitoring (IoT) with SMS alerts, GDP-style logging on dairy/pharma nodes
- Optional cold-truck pooling + solar EV charging for last mile

Calculators
FAQ
Solar cold hub with or without batteries?
Chilled duty can run on PV + ice-bank/PCM thermal storage with zero lithium battery for 24–48 h autonomy. Frozen duty typically needs LFP BESS or a hybrid grid/genset tie.
Which refrigerant is best for solar cold rooms?
R290 (propane) dominates because DC-inverter compressors modulate efficiently on variable PV power. R290 is Kigali-compliant, low-GWP, and future-proof.
How does ColdMatch source solar off-grid networks?
We brief 3–5 audited solar cold-hub OEMs and EPC integrators against a structured network spec (hubs, PV, BESS/TES, tariff model) and benchmark CAPEX / LCOE / lifecycle OPEX vendor-neutrally.
