Kent-based solar installer Blue Sky Energy Solutions has secured a “colossal” investment worth £50 million from German developer Wirsol.

Wirsol has invested in Blue Sky to enable the firm to help make commercial rooftop installations more affordable for firms in the UK, something Blue Sky has said promises to be “game changing” for the company.

“The plan is to break up the ‘market place economics’ of the Big Six energy firms and put it in the hands of communities and small local companies,” a company statement said.

The investment is an expansion on the two parties’ current partnership which has seen Blue Sky fit 3MW of commercial rooftop arrays to date, with an additional 5MW currently in the pipeline.

Wirsol has remained active in the UK market despite selling subsidiary Wirsol Solar UK to Conergy in January last year, connecting 29MW of solar projects in the country prior to the 1.4ROC deadline in April.
