Techno- Economics of a Hybrid Photovoltaic Wind Turbine (original) (raw)

Social Science Research Network, 2021

Abstract

To improve the overall energy production from the wind turbine and lower the levelized cost of energy (LCOE), an innovative approach for the design of a hybrid solar-wind turbine (HSWT) is proposed. The present concept is based on installing arrays of solar panels on the south-facing facade of the turbine tower to generate electricity from sunlight. The hybrid offers greater benefits compared to separate systems. An example is given of an offshore WT with a rated capacity of 4.7 MW forming part of a 600 MW wind farm in the North Atlantic. The 100 m high tower is covered with 465 PV panels of 340 W capacity. For evaluation, the gross resource of each renewable is estimated considering the specifications of the available data In the discussion, the LCOE’s of wind and the hybrid solar-wind combination are compared. From the results, it is clear that HSWT offers a reduced LCOE, even after allowing for shading losses from the blade, and a much steadier production of energy. The introduction of HSWT would help to make wind farms a more cost-effective and competitive source of clean energy.
