TSSC is harnessing the power of the sun to help the transport refrigeration industry keep cool en route. Our innovative range is the use of solar panels to power the refrigeration units. This application is suitable for refrigerated trucks & trailers designed to maintain refrigerated conditions of the insulated box, which must be able to operate at chiller temperatures (+1 0 C).

Solar Powered Trucks

Our recent addition to the innovative range is the use of solar panels to power the refrigeration units. This application is suitable for refrigerated trucks & trailers designed to maintain refrigerated conditions of the unit, which must be able to operate at both freezer (0°F) and refrigeration (38°F) conditions.
Developed specifically to power the transport refrigeration unit (TRU) and maintain the battery charge, the new Thin-Film Flexible Solar Panels are easily installed on the roofs of trailers, truck bodies. The unit saves fuel and reduces downtime lost to dead batteries that may be drained by not keeping the engine running to power the refrigerated trailer.

  • Less Energy Consumption - Harnesses the energy of the sun
  • Cost Savings on Fuel - Eliminate idling and additional engine load through compressor, bracket and belt assembly
  • Low Maintenance - Eliminate additional load on the engine vehicle ( No bracket, belt or compressor )
  • Vehicle engine failure does not effect the cooling system
  • Less Noise Pollution
  • Long life Battery
  • Green Technology - Elimination of emissions associated with diesel exhausts and global warming
  1. Considerably less energy
  2. Low maintenance due to fewer moving parts
  3. Less noise pollution
  4. Elimination of emissions associated with diesel exhausts
  5. Engine failure does not effect the cooling unit

The innovation uses a variable speed, direct current (DC)cooling system, connected to a solar photovoltaic (PV) panel via electronic controls.
Specially designed thin Photovoltaic panels are mounted on the roof of the truck which generate power for the refrigeration unit. The DC electrical power drives the compressor to circulate the refrigerant.
This maintains peak performance in an environmentally sustainable way and helps conserve fuel unlike the traditional method of providing power by running the vehicle diesel engine of the vehicle or cooling unit.
When exposed to daylight, these panels continuously charge the TRU batteries which store thermal energy for ecient use when sunlight is absent.
The CELSIUS S-Series unit also includes a solar controller that regulates the state of the charge in the battery. This prevents the battery from overcharging and extends battery life. It also directs power where needed (to the crank battery, for example). The solar controller is waterproof and can be mounted in a wide range of locations on the truck.
The solar powered cooling unit also operates on a low acoustic value (creates less noise) compared to diesel engine.

Two 12 V 200AH deep cycle batteries are installed on the left & right side of the chassis. When the vehicle is stationary or during the hours of darkness the Solar PV Panels will charge the batteries. However, during transit the truck self-alternator will produce the DC 24V electrical power to charge the batteries.
A solar controller regulates the state of charge in the battery, which maintains the health and extends the battery life. 10 or 30 amp solar controller helps prevent batteries from overcharging

At present, most chilling equipment is powered by diesel generators. These have high energy demands and maintenance costs, as well as environmental impacts both in terms of emissions, which contribute to the greenhouse effect, and noise levels.
In comparison, the solar-powered refrigeration unit offered by TSSC uses considerably less energy than a standard diesel-driven unit and by improving the vehicle’s insulation and design we enable to keep it operating throughout the year.
