The problem

Installing a high-voltage pylon involves quite a lot. Ironically, electricity is of course needed to get the mast in place, but also so that a construction site can be put into operation. Normally, standard diesel generators are used for this purpose, or in some cases a more sustainable so-called HVO B100 biodiesel generator. However, the realisation of a new high-voltage pylon prompted Van Hoek Bouw BV to start a pilot with a solar generator from Volta Energy.

The objective

In the realisation of the foundation of a high-voltage pylon by Van Hoek bouw, one thing is of course very important: power. The aim is to provide all the power needed for the work by using a Solar Power Generator from Volta Energy. Indeed, this will not only make the construction work more sustainable, but will hopefully also allow for substantial financial savings.

The challenge

The challenge? Providing all the power needed to make this foundation, in a sustainable way. When installing the high-voltage pylon and the construction shack, providing sustainable electricity. In terms of costs, this should also provide an advantage over diesel generators.

The results

In the end, the Volta Energy Model 15 kVa ran for 34 days alongside a diesel generator and a VO B100. In this, the solar generator consumed only 120 litres of diesel in an emergency, where the other two consumed over 3,200 litres. During the pilot period, the solar generator generated as much as 254 kWh of renewable energy through the solar system, where 303 kWh were consumed. In total, this saved over €2,200 compared to the two conventional generators.

In addition to the significant savings, the use of the solar aggregate was also perceived positively by the workmen. A nice environmental gain was also achieved. Indeed, compared to the conventional diesel generator, the solar generator saved over 10,000 kg in CO2 emissions and almost 15 kg in NOx emissions. Also compared to the HVO B100, over 1,000 kg of CO2 and 15kg of NOx were emitted less. In addition, more than 3,000 litres of diesel were saved. All in all, a positive pilot of the 15 kVa solar generator for Van Hoek Bouw BV.

Choose your model

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..
