Solar Refrigeration


Malta benefits from at least 30000 hours of unbroken sunshine every year. The potential for energy reduction makes our product more attractive as this results in substantial savings of 40% to70% reduction in electricity consumption during SUNSHINE HOURS thus producing more UV AND MORE ELECTRICITY CONSUMPTION SAVINGS, together with

  • Reduce Electricity overhead
  • Reduced ongoing equipment maintenance costs
  • Extended lifespan of equipment
  • Reduced CO2 production

How it Cools

Once refrigerant is compressed the vapour gas gets hot. The warmer it is and the higher the UV rays, the more the solar panel takes over.


  • The refrigerant comes into the compressor as a liquid gas, it is compressed and then moves out the compressor as a vapour gas.
  • The generated vapour gas at approx. 70 degrees Celsius coming out from the compressor and flows to the Solar panel. This gas meets already heated and pressurised gas generated by the Solar Panel. The gas mixes and passes through the condenser with higher volume. Thus the second stage compressor remains idle.

This above is a brief description of how the system works and where substantial energy savings are generated.

Monoblock type refrigeration systems are ideal in Malta as they are low-cost, quick and easy to assemble and give high energy efficiency within a compact unit. Within these systems, the condensing unit and compressor connect to evaporation unit.
Split-type refrigeration units are ideal for areas where a lack of space outside the cold room prevents a monoblock unit installation. The evaporating unit is therefore installed separately inside the cold room and the condenser and compressor could be installed outside of the building.
Central unit refrigeration systems are the most suitable systems for larger industrial purposes in Malta as more than two compressors could be installed on the outdoor unit. The central unit works depending on the demand for cooling by a programmable logic controller. All compressors have their own separate protection so if a single compressor is faulty the other compressors are not compromised. Central refrigeration units also come with the latest compressor technology and electronic expansion valves, resulting in higher efficiency and thus reducing consumption by 35-50% over traditional refrigeration systems in Malta.


It is important that food related items must be stored within strict temperature ranges, otherwise the risk of increasing the spread of food borne illness is a reality. Furthermore temperature changes or refrigeration failure can ruin thousands of euro worth of food. In order to avoid situations, different levels of services and reports can be provided to suit the particular client where the systems can be controlled through your PC and even from your own mobile thus giving you a peace of mind even when away from your desk.


A case study was performed on a 40 thousand sq ft site on of Malta’s leading manufacturer consuming approx. 606 hwh per day which translates into an expense equivalent to Euro 39,000 p.a.

Post SolarCool installation results are showing an equivalent of c/a 391 hwh per day which is an equivalent of Euro 26,000 p.a thus creating a saving of over Euro 13,000 p.a

So…53% when the sun is in the sky, and a 33% saving over the 24 hours operation with a return on investment of 2 years.

Over a five year period, this investment will return a projected flat rate of c/a Euro 65,000.
