Solar refrigerators are reliable, efficient, and affordable. Their operating cost is 50 percent less than that of equivalent models that use grid-tied electricity. Many commercial facilities use diesel generators to power their refrigeration systems. They can achieve at least 80 percent saving by switching to solar-powered refrigerators. These ‘green’ cooling machines are equipped with a thermal battery system that helps to store solar energy during the daytime and draws on the grid-tied electricity during the night. The battery system comes complete with a centralized electronic control that, besides running the entire unit, also optimizes the use of available solar and grid power. The whole mechanism, in turn, helps the refrigerator’s energy consumption at the minimum level. Some models are also equipped with a hybrid-power optimizer that facilitates an efficient transfer of solar and grid power for optimum distribution of electrical loads between the two.

Below are a few commercial applications of these energy-efficient units:

Vaccine Storage

Expensive life-saving vaccines can get spoilt if not stored at a recommended temperature. Reliable power supply is required to keep these refrigerators running unhindered. Supported by solar PV arrays, these refrigerators enjoy a constant power supply thereby eliminating the risks of medicines going bad due to power outage and subsequent warming up of the fridge.

Preservation of Agricultural Products

When it comes to preserving perishable food items, solar refrigerators provide a practical cooling solution, especially for the isolated rural areas that have limited access to electricity supply. Thanks to their simple, electronics-free mechanism, solar refrigerators are easy to use and maintain.

Mission-Critical Applications

Many demanding applications need refrigeration 24X7. The hybrid nature of solar refrigerators (the battery utilizes grid electricity when there is no sunlight to tap) ensures an uninterrupted power supply. Many organizations use these hybrid systems to power milk chillers.

It will be worthwhile to mention here that usage habits, location, and variation in seasonal temperatures affect the amount of required power significantly. Therefore, usage and maintenance training is an integral part of the installation of a solar refrigerator. If you are contemplating a switch to the PV-tied refrigeration system for your commercial establishment, for consultation or installation assistance.
