A container refrigeration room needs a dependable power supply to keep its refrigeration system operating at the required storage temperature. In locations where grid access is limited or electricity costs are a concern, solar power can provide an additional energy source for cold storage operations.
PAULAIR Container Refrigeration Room Solar Panels solutions are designed for integration into container cold storage projects that use solar energy. The solar panels can form part of a power system with suitable energy storage, inverters and refrigeration equipment, depending on the project configuration.
Rather than selecting panels by wattage alone, the system needs to account for refrigeration load, daily operating hours, local sunlight conditions and available battery capacity. These factors help determine whether the solar power system can support the intended cooling operation.

Refrigeration equipment may operate for extended periods, including when sunlight is unavailable. Solar panel capacity, battery storage and refrigeration power demand therefore need to be considered together.
Panel output should be assessed against local solar conditions and the energy required by the refrigeration system. The available installation area and panel arrangement also affect the final configuration.
Battery storage can retain available solar energy for use outside peak sunlight hours. Its capacity should reflect the required operating time, refrigeration load and expected charging conditions.
The solar power arrangement must match the electrical requirements of the compressor, fans, controls and other connected equipment. Inverter selection and starting current are important considerations.
A solar-assisted container refrigeration room can be considered for sites where a conventional grid connection is unavailable, restricted or expensive to extend.
Actual suitability depends on the local climate, storage temperature, refrigeration capacity, operating schedule and available power sources.
The correct solar setup starts with the cold storage application, not a standard panel quantity. PAULAIR evaluates the project requirements to help establish a suitable refrigeration and power configuration.
| Storage temperature | Required cooling temperature and the temperature range the refrigeration system must maintain. |
|---|---|
| Refrigeration load | Cooling capacity, compressor power, fan consumption and other electrical loads. |
| Local sunlight | Solar conditions throughout the year, installation orientation and available panel area. |
| Operating schedule | Daily running hours, expected night-time operation and acceptable backup power arrangements. |
| Energy storage | Required battery autonomy, charging conditions and compatibility with the power conversion system. |
