This 41.4 kWp system was installed during February on a barn roof near Blandford, on behalf of The Crown Estate. Being installed in a farm environment, the ammonia resistance of the Solar Frontier modules was a helpful additional feature. And although the roof size was a limiting factor to the overall capacity in this installation, the return on investment for the 41.4 kWp Solar Frontier based system proved more than competitive with conventional modules.

During the first two months of operation, the system achieved very strong yields despite a fault in the local grid that limited the system’s peak performance and the wettest April in England since records began. The performance confirms the excellent suitability of Solar Frontier modules for challenging environmental conditions. The owners and local tenants are very pleased not only with the performance, but also the beautiful appearance of the system.
