Sturm
Solar energy takes company by storm with clear arguments
The inauguration of the new solar energy system on the roofs of the Sturm Gruppe (meaning „storm group“) in Salching, Lower Bavaria, was quite literally a stormy celebration. This solar power plant with a total capacity of almost a megawatt
(940 kWp) is one of the largest in the region, and was installed by Phoenix Solar at a nigh-on record-breaking tempo in just ten weeks.
The fundamental requirements for the punctual realisation were the innovative system concept, and close cooperation between Phoenix Solar‘s construction management and the company Sturm‘s logistics. In total, 13,680 thin-film modules from the manufacturer First Solar were installed. The mounting system chosen was Tecto-Sun Plus from Phoenix Solar, as this was perfectly suited to the roof structure.
To avoid excessive wind loads on the roofs, the solar modules were installed parallel to the roof surface, so additional elevated mounts were not required.
The target yield of over 900 kWh/kWp was largely achieved due to a sophisticated system of thin-film modules and a distributed inverter concept.
