Key benefits

1
Stable Energy Costs
Solar thermal boiler represents a significant cost reduction in any industrial scale production. In comparison to fossil-fuel based boilers, manufacturers are saving up to 75% in their boiler systems.
2
Energy Security
Solar steam boiler provides uninterrupted and always- dispatchable energy at an affordable cost. Solar thermal boilers mean that industrial customers are no longer dependant on fossil fuels.
3
Sustainable Technology
Solar energy is green and produces zero CO2 emissions. Our technologies help our customers to become climate neutral, helping to put a value on their negative CO2 emissions through the internal carbon tax mechanism.

We decided to introduce solar steam boilers to our fruit juice production plant in Cyprus in 2019, reducing the fuel consumption of our conventional boilers and covering various production processes such as pasteurisation. The solar system provided by Protarget has proven to be a reliable and cost-effective source of thermal energy significantly reducing our fuel consumption and CO2 emissions.
