Solution Overview

Problem

Conventional photovoltaic and wind power generation installations require large amounts of space due to shading effects and spatial separation, leading to inefficient use of land and increased costs for remote installations, with photovoltaic modules being functional only during daylight hours and wind turbines only at night, resulting in an intermittent power supply.

Innovation Solution

Combining photovoltaic arrays with wind turbines, where the photovoltaic arrays are partially shaded by the wind turbines, utilizing bypass diode arrays to prevent complete module shutdown from shading, allowing closer placement and integrated power generation with wind turbines, and incorporating solar and wind tracking mechanisms for optimal energy capture.
