The managing director of PV mounting systems specialist Renusol, Stefan Liedtke, left the company at the beginning of this month, with his replacement joining from rival firm Schletter.
Liedtke has been with Renusol for five years and was previously head of sales and marketing. On leaving the company at the end of September, he sent a letter notifying contacts and business associates, including PV Tech, that his departure was effective as of the beginning of October.
Renusol was taken over by US company RBI Solar in 2014. Its products include the MetaSole for trapezoidal sheet metal roofs, and VarioSole, which is for tiled roofs, as well as a number of flat roof, ground mount and flat roof integrated PV mounting systems. The company also claims to have been among the first to promote East-West orientation commercial rooftop mounting systems in Europe. The most recent volume of PV Tech Power, Solar Media's technical journal for the downstream PV sector, featured a discussion of cost reduction measures and innovations in the commercial rooftop mounting sector, in which Renusol was profiled, along with SolarCity subsidiary Zep Solar and Chinese-Australian company Clenergy.
At the beginning of this year the company also launched a ‘universal clamp’ for residential installations. RS1 can be used as either a mid- or end-clamp, using a simple swivelling and locking mechanism, winning industry awards this summer.
Lietdke’s replacement Sven Künzel will take over the role on 1 December, with Renusol management colleague Dieter Heck taking over in the meantime. Lietdke’s permanent replacement Künzel was previously international sales manager at the US subsidiary of Schletter. According to Lietdke’s farewell letter, Künzel has extensive experience of mounting systems in the ground mount PV sector.
