From July to the present, Gebroeders van Kessel and Volta Energy have teamed up to achieve a sustainable construction site. At the Eldens dike site, a 40 kVA diesel generator was previously running. This 40 kVA generator was running 24 hours a day, 7 days a week. This was in connection with 24/7 camera security. Average diesel consumption was around 400 litres per week.

To provide van Kessel’s work with all necessary energy, sustainably of course. Appropriate solutions must be found at various locations in Arnhem to supply the construction site, container and electrical equipment. As fits exactly within the shared mission to strengthen the energy transition.
The challenge? Providing all the power needed to carry out work in and around Arnhem. Several locations such as Elden’s dike and the bridge on Apeldoornseweg need to be supplied with sustainable energy. For financial purposes, this should also prove advantageous compared to diesel generators. Less cost and still more sustainable!
At various locations in Arnhem, the 15 kVA Solar Aggregate & 45 kVA Solar Aggregate powered the construction shack, container and electrical equipment as sustainably as possible. After the work on Eldensedijk was completed, work started on the bridge in Apeldoornseweg over Cattepoelse weg. During this work, electrical tools were used significantly more. This required higher power, which the newly released 45 kVA Zon-Aggregaat (solar generator) is perfectly capable of delivering.
With the arrival of the solar power generator, as much energy as possible was supplied from the solar panels in combination with the battery pack. This way, energy could be used without emissions. Should additional energy be needed for an emergency, an automatically switched-on back-up biodiesel aggregate (HVO100) could be used.
In addition to the huge savings in CO2 and NOX, the solar aggregate also had an overall lower price than the conventional diesel aggregate. A conventional diesel aggregate always supplies energy, even at times when virtually no energy is required. A diesel genset should always run at 1500 rpm. On this construction site, an average of 0.85 kW was used. The diesel genset is designed to generate 16 kW (20 kVA) on average. This difference results in a huge energy efficiency loss. The backup biodiesel in the Volta Solar Generator delivers its electrical power to the battery. Thereby, all energy is ‘harvested’ from the diesel genset. This yields the highest possible efficiency and thus a large diesel saving.
In addition to these Diesel, CO2 and NOX savings, the solar power generator has caused less inconvenience to local residents, had a positive influence on the image of the construction site on the neighbourhood and provided a sustainable image.
The power generators come in different sizes - from 6 kVA to 120 kVA - so that all construction sites and events can be supplied with renewable energy on site. Our bio-solar-hybrid generators are more sustainable than conventional diesel generators and hybrid diesel-battery generators. When the sun is not shining, our generators automatically switch from solar to battery and then to bio-diesel genset. This way, we make sure you always have power..

We have been renting a solar generator for our work in Armhem for over six months now. My experience during that period with Volta has been more than positive, committed people with an eye for customer and quality.

We asked Roel to help think about our Sun in the City project. He was immediately enthusiastic and came to our rescue. We used the Volta Energy Naos for a co-creation session at a neighbourhood party in Rotterdam. We were able to connect our computer with VR glasses directly to the system - that impressed the neighbourhood a lot! In addition, the system was enthusiastically used by the food stalls at the festival.

Cool solar-based green power supply, coming with an incredible nice service. Very friendly, very helpful, everything gets installed and checked. Great team!
Jeanine Roelse
For the Lower House elections in the municipality of Rotterdam, we gratefully used Volta Energy's solar generators. Volta delivers more than just a beautiful and reliable product with a positive message and functional purpose. Roel made a tremendously positive contribution to this project throughout the entire process, thereby relieving us of all our worries.

Fine service, good coverage and our entire event ran on solar power: top!

Sustainable, reliable and, on balance, cheaper than a diesel aggregate. Rented on behalf of Boskalis Netherlands.
Michael Verstraeten
An innovative, professional and dynamic company is Volta Energy. Very helpful and with a problem-solving mindset. Very nice experience to work with and hire.
JW van der Klugt
Working with Volta Energy for the first time. This turned out well. A company you can make good agreements with (which they then honour) and they have nice equipment. Worth repeating.
