Longi Solar Panels

Longi is the world's largest producer of mono silicon wafers, supplying more than 30GW of solar wafers and modules across the globe yearly, accounting for around a quarter of global market demand.

Longi invest heavily in R&D, and their panel production arm specialises in monocrystalline, manufacturing exclusively high output PERC and bi-facial modules for supply to both utility scale projects and distribution.

LONGI has earned the Ecovadis Gold Medal, meaning they are in the top 5% of companies assessed by EcoVadis for their sustainability management system and commitment to promoting transparency throughout the value chain.

By treating their PERC cells to reduce light-induced degradation, Longi panels offer a better lifetime yield than standard mono panels.

Midsummer are proud to be an Authorised Distributor of Longi products for Europe.
