Shared solar cold storage lets growers purchase cooling services instead of buying a complete installation. However, a functioning cold room is not automatically a sustainable business. Demand, charging rules, daily cooling capacity and operating responsibilities should be established before equipment is ordered.
For a cooperative or collection center, a FLAND solar container cold room should be assessed through usable crate positions, daily intake capacity and power requirements together.
Identify users and product flows
Define whether customers are growers, traders, market vendors or cooperative members. Record arrival times, crate sizes, crop mix, expected storage duration and collection arrangements. Without an outbound plan, slow-moving stock can fill the room and prevent new produce from entering.
Separate storage capacity from daily cooling throughput. Warm incoming products impose a load that is not necessarily reflected by the billing unit. Receiving schedules should respect the equipment's cooling duty as well as the number of empty shelf positions.
Documented example: paying for storage by the crate
A USAID technology case study documents ColdHubs’ Nigerian pay-per-use approach.[1] The relevant principle is access to a service without owning the full installation. Historical fees should not be copied into quotations for another market.
Match charging rules to local trading habits
| Charging basis | Where it can fit | Terms to define |
|---|---|---|
| Per crate per day | Relatively standardized reusable crates | Weight limit, start time and partial-day rules |
| Per kilogram per day | Weight-based trading | Tare weight and receiving/dispatch checks |
| Pallet or storage position | Larger, regular deliveries | Height, occupied space and temperature zone |
| Reserved monthly capacity | Stable contracted users | Minimum commitment, excess use and cancellation |
Product value alone is a poor proxy for the space and cooling capacity consumed. Under any system, define responsibilities for uncollected goods, damaged packaging and products that do not meet receiving requirements.
Worked example: utilization matters more than nominal capacity
Assume a proposed layout and load assessment support 100 standard crate positions. At 60% average paid occupancy, $0.40 per crate-day and 30 days per month, gross revenue is 100 × 60% × $0.40 × 30 = $720. At 30% occupancy, it falls to $360.
These are teaching assumptions, not ColdHubs prices or FLAND project returns. If monthly fixed operating costs are $450 and variable cost is $0.05 per paid crate-day, operating break-even is $450 ÷ ($0.40 − $0.05) ÷ 30, or approximately 42.9 occupied positions daily. That is roughly 43% occupancy.
This calculation excludes equipment financing and investment recovery. Add those costs to a complete business plan rather than treating operating break-even as full profitability. Seasonal demand also needs separate treatment; a busy harvest month does not establish annual occupancy.
Billing rules do not replace product management
Crops with different temperature, humidity or ethylene requirements may not belong in the same space. Establish an accepted-product list and suitable separation. Record owner, product, quantity, arrival time and storage position for every batch. Plan access so that earlier arrivals are not trapped behind newer stock.
Assign named responsibilities for cleaning, door management, temperature checks and payments. The solar system also needs inspection and a low-energy response procedure. An installed display is useful only when someone checks it and knows what to do.
Validate demand before expanding
Survey seasonal supply and willingness to pay before choosing the first installation. Expansion should consider power, refrigeration capacity, handling space and staffing together. If equipment will move between growing regions, include transport downtime and recommissioning in the service calendar.
Translate shared-storage operations into a FLAND layout
Plan FLAND container cold rooms as a central storage unit, with numbered crate positions, aisles and receiving space defined before ordering. For a smaller first phase, also compare a FLAND mobile room rather than investing only against an optimistic harvest-season forecast.
Cross-check the equipment against the charging model: the same 100 positions can impose a different duty when arrivals are warmer or doors open more often. Coordinate later capacity additions with energy and staffing. FLAND equipment supplies the storage infrastructure; local demand and management determine the business outcome.
Frequently asked questions
Does solar power make the service free to operate?
No. Staffing, cleaning, repairs, replacements and capital costs remain.
How many farmers can one room serve?
It depends on each user's batch size, storage duration and arrival schedule. Room dimensions alone cannot provide a meaningful number.
Should the first purchase be the largest available room?
Validate recurring paid demand first and establish a practical expansion route.
Share the operating plan with the supplier
Give FLAND your crop mix, billing unit, standard crate dimensions, intake schedule and average storage duration. Ask the shared cold-storage proposal to identify usable positions, product-cooling duty, solar equipment and daily operating requirements.
Plan shared storage around crate positions and turnover
Share your location, product and operating requirements with FLAND to discuss the configuration and delivery scope for this application.
