ConSole/ConSole DS: The patented PV flat-roof system by Renusol tested by the TÜV


The installation of PV systems on flat roofs presents considerable challenges with respect to high wind loads, the optimum irradiation angle and the allowable roof load. With ConSole, Renusol GmbH has developed a PV mounting system that is tailor-made specifically for the requirements of flat roofs. It can be set up safely, quickly and simply, without having to pierce the roofing. ConSole has been marketed by Renusol for more than 10 years and has since then turned into the ballast system par excellence in Europe.

Special system advantages
The ConSole system is as simple as it is effective. The module supports are extremely light plastic tubs that are deep-drawn from weather-resistant HDPE. Depending on the building height, allowable roof load and wind load to be expected, they are weighted with gravel or quarry tiles and positioned on the roof according to irradiation. Thanks to the ballasting, penetrating the roofing is not necessary for anchoring, eliminating the risk of damages due to leakage. After installing the ConSole ballast tubs, the PV modules are screwed onto the ConSole tub edges by means of the aluminium profiles (U-profiles) that are part of the system. The ConSole ballast tubs have the optimal inclination angle of 25°, which results from maximum irradiation and minimum shading. An artificially produced "stack effect" ensures the ventilation of the modules, which removes the hot air through openings on the sides between module and tub. Reduced yields due to overheating are thus avoided.

HDPE is extremely stable and UV-resistant and can be used in temperatures between -40° and 85°C. With its approximately four kilos of weight, each ConSole has only little effect on the roof load. On gravel roofs, the tubs can be filled with the gravel from the covering layer; thus the load for the roof remains almost unchanged.
The proven ConSole system is suited for mounting practically all framed PV modules with 34-51 mm frames.

Thanks to outstanding material characteristics and gentle installation, they are maintenance-free. The system and accessories are tested by the German Technical Inspection Association (TÜV).

ConSole DS
For thin-film modules, ConSole was developed as DS version. In this version, special clamp profiles are screwed onto all four sides of the ConSole ballast tub. These keep the module uniformly in place, thus distributing the pressure uniformly onto the whole module side. Another difference to the standard ConSole is that PP (polypropylene) is used for ConSole DS ballast tubs instead of HDPE. ConSole DS has been available since January 2010 in the common dimension of thin-film modules of 1.10 m x 1.30 m.
