The projects - Tir Mostyn, Wales, Scout Moor, Lancashire, and Bagmoor, Lincolnshire - were purchased for around €300 million by Munich Re's MEAG Munich Ergo Asset Management division.
According to reports, Munich Re is looking to invest around €2.5 billion on renewables assets.
HG Capital acquired Tir Mostyn - its first wind farm - in 2005 for £21.6 million. The plant consists of 25 Gamesa 850kW turbines.
At the time, HG said the acquisition was the first of a series of investments in renewable energy projects in western Europe.
Last year, Munich Re has signed a deal with Fuhrländer to insure the wind turbine manufacturer's five-year guarantees. It was the first insurance cover of its kind for the wind-energy sector.
