Ibis Energy has developed a rooftop system that mixes photo voltaic and wind generators designed for medium-sized buildings and high-rise buildings. It claims its PowerNEST system can produce six to 10 instances extra power than standalone rooftop photo voltaic. The corporate has already put in 5 initiatives within the Netherlands.
Ibis Energy, a Dutch renewable structure specialist, has developed a hybrid photo voltaic and wind energy system for the roofs of buildings with not less than 5 flooring. The corporate claims that the prepared system can produce six to 10 instances extra electrical energy than standalone rooftop photo voltaic.
“PowerNEST facilitates the circulate of air to the generators rising their output by 4 instances, but in addition will increase the facility output of the photo voltaic panels by 30% to 40% by directing the air to actively cool the panels from under,” CEO of Ibis Energy Alexander Alexander. Suma instructed pv journal.
The modular resolution features a row of three kW wind generators topped by bifacial panels that seize mild reflections inside its white cladding. Every module measures 7.2 meters by 7.2 meters, with a peak of 4.8 meters. The corporate has already put in the answer in 5 initiatives throughout the Netherlands, most not too long ago within the HaasjeOver constructing in Eindhoven.
The HaasjeOver set up consists of 10 PowerNEST modules. In complete, it has 240 bifacial, 396 W photo voltaic panels and 56 335 W monofacial panels, for an annual energy output of 116 MWh. It consists of 4 3 kW wind generators with an annual output of 24 MWh, bringing the overall photo voltaic and wind output to 140 MWh/yr. This covers 85% of the tower’s power wants, Suma stated.
PowerNEST is put in a number of meters excessive from the roof, so it covers extra roof area than is out there.
“The roof earlier than set up solely had area for about 40 photo voltaic panels which needed to match between the air flow pipes, different utilities, the roof edges, and their shadow ,” defined Suma. “It generates solely 11 MWh/yr to 12 MWh/yr, which is 10 instances lower than PowerNEST.”
The €800,000 ($827,570) HaasjeOver challenge was delivered as a turnkey resolution.
“It is the precise value of such a challenge if you wish to make it structurally secure, use sustainable supplies and meet the constructing code,” Suma stated.
He stated he expects prices to lower as the corporate continues to increase. Ibis Energy is presently creating 12 extra PowerNEST initiatives within the Netherlands and increasing to different components of Europe and the USA.
