With our high-performance modules and our special, storm-proof stainless steel holders you provide your boat with power. Despite the EU-imposed punitive tariffs we are still able to offer you our extra sturdy framed, black anodized mono crystalline modules. Iit is a product of the U.S. brand SUNPOWER, the finishing and framing will be made in China. Do not confuse these systems with conventional 12 volt systems to trickle charge the onboard batteries or walk-in, flexible cells. We do not offer such techniques, because they permanently unable to work, not stable enough, and especially the performance is far short of the promises by manufacturers. Our systems operate at much higher voltages, which are adapted about MPPT controller to the power supply. Each system is completely maintenance free and works in any weather. The modules are optimally aligned to the sun with special stainless steel brackets without interfering in the harbor. We assemble most at the side of the stern or at catamarans or yachts with targa bar above. Our modules are available pre-assembled ready to mount.
