The system allows framed photovoltaic modules to be mounted exceptionally quickly and can now also be used on trapezoidal sheet metal roofs with thicknesses between 0.4 and 1.5 millimetres. Only a few components are required for the modules to be directly fastened to the roof, namely a clamp base, two thin sheet metal screws with a special coating, one end clamp and one middle clamp, and the modules are fixed without the need for mounting rails. The same screws can now be used for both aluminium and steel trapezoidal metal sheet roofs.
The MetaSole mounting system is now even easier to use, reducing the mounting time to less than ten minutes per kilowatt peak (kWp) of power installed, states Daniel Theophil, product manager at Renusol. Systems which are quicker to mount currently have a clear advantage over their counterparts installers relatively stable salaries are counterbalancing falling module prices, leading to installation costs becoming increasingly decisive for the systems rates of return, Theophil adds.
MetaSole screws also boast cone points which penetrate the material, meaning there is no need for pilot drilling and the mounting time is reduced further. The screws leave behind virtually no bore chips, resulting in no damage being inflicted on the roof and EPDM rubber used in the mounting system. The system is suitable for roofs with ribs at least 20 mm wide, regardless of the intervals between the ribs. A further advantage of MetaSole systems is that distributors and fitters can save money on storage and transportation costs.
The mounting material needed for a solar system with an output of 3.6 megawatt peak (MWp), for example, fits into four Euro pallets. Press photos are available for download at: http://www.renusol.com/en/company/news.html Further information about MetaSole can be found at: http://www.metasole.com
