The system has been installed on one of the turbines towers of the Breña Wind Farm in Albacete, Spain, which ACCIONA owns and operates. The turbine is an AW77/1500 of Nordex-ACCIONA Windpower technology, mounted on an 80-metre-high steel tower (hub height). The 120 solar films - facing southeast-southwest for optimum use of solar radiation - cover approximately 173 m² of the tower and generate a total power of 9.36 kWp.
“Awesome to see Heliatek’s OPV solution enable hybridization of wind-energy on Acciona Energia’s Wind-turbine in our landmark project in Spain. Heliatek’s organic solar films fit seamlessly on the 80m high wind-turbine tower,” said Heliatek CEO Guido van Tartwijk.
According to the official ACCIONA press release, this new photovoltaic system will support the auxiliary systems of the wind turbine. Certain systems continue functioning also in shutdown mode, when there is no sufficient wind, sourcing power from the grid. Heliatek OPV films will be able to cover the energy demand related to the operation of the wind turbine when the sun is shining and even - in a possible later phase of the project – without sun irradiation by using a battery system. This will lead to the wind turbine to be operating without utilization of any grey electricity from the grid.
