IM Efficiency CSO

In this first year we already see that the SolarOnTop is delivering 60-70% of the energy demand. This Way the alternator is running less hours what also means a higher uptime of our trucks and batteries. This is a big advantage for our customers and employees. Because Heisterkamp can offer all the services a high grade of trust.

Heisterkamp Transport B.V

Chief operating officer.

Every initiative aimed at reducing emissions deserves careful consideration for its feasibility. Thanks to the SolarOnTop solution, we effectively cut our truck's fuel consumption by a percentage that justifies the investment and enables us to make a step towards a greener environment.

For us, the motivation was to ensure that the air conditioning and refrigerator continue to work during the break in the daytime (in our work, the moment when we go to sleep). We now have a perfectly working system in which the driver can enjoy a cooled break, even in temperatures above thirty degrees without running the vehicle.
