Midsummer has entered a partnership with Chinese maker of thin film solar panels Kaisheng New Energy Technology. Kaisheng will manufacture thin film roof top products for Midsummer based on Midsummer's certifications and quality assurance, and Midsummer will have exclusive roof top rights to market these panels in Europe. Midsummer has signed an OEM agreement with Kaisheng for the production of thin film solar panels, based on a similar but slightly different CIGS thin film solar cell technology from what Midsummer has developed but with Mids summer's certifications and quality assurance.

Midsummer will have exclusivity to the European roof top market for these panels. The new product will be marketed in Europe as BOLD S. It is very similar to Midsummer's own model a panel specifically developed for large flat or near flat low load bearing BOLD, roofs on mainly commercial and industrial buildings. The two parties will jointly develop in the areas of technology and material supply to further improve the product's functionality and production cost.
