The document summarizes a proposal to integrate solar power generation at the Lillgrund offshore wind farm in Sweden. Currently the wind farm has 48 turbines that generate around 330 GWh per year. The proposal evaluates installing solar panels between the wind turbines to generate additional power from solar energy. Simulation results estimate the solar installation, with panels at a 30 degree tilt, could generate around 220,599 MWh per year. Combined annual generation from wind and solar is estimated to be 545,372 MWh, providing more stable power production throughout the year. The integrated system could help utilize existing infrastructure and reduce maintenance costs for the wind farm.

- 12. Special requirement at lillgrund Frameless panels. High-density polyethylene structure. Solid base between turbines stand over concrete pillar. The suggested types of foundation are: • Floating base made of polyethylene. • Concrete base with fixed foundation. • Floating base with damper on edges to slow down the foundation vibration. Solar inverters to be installed next to wind turbines. All materials shall comply with environment condition and requirements.
- 13. Shade effects on solar array: Soft shade • The current drops proportionally to the reduced irradiance. • Voltage would be the same as long as there is enough light (~50W/m2). • The temperature and the electron band gap control the voltage of the PV cell. Hard shade • If the cell fully shaded then no current will move out of the cell, and the voltage will breakdown.
