• Offer Profile
  • AkoTec develops and produces Vacuum tube collectors exclusively for OEM, i.e. industrial customers, specialist dealers and distributors, who offer the systems under their own brand names.

    Everything „Made in Germany“: tubes, manifolds/header and collectors are manufactured in Germany. This includes not only more jobs in Germany, but also highest quality.

    Only German manufactured vacuum tubes from the Narva Company are processed in Ako Tec -collectors.
Product Portfolio
  • Our Products

      • AkoTec – collector distinguish themselves from others through enormously high performance, less weight, quick assembly and high quality design.

        The most powerful collector in the market is our OEM Vario 3000 with maximum power of 3014 Wp, that equates a power per m² of 615 Wp. Our collectors are manufactured also with 10 vacuumtubes (1000 Wp) and 20 vacuumtubes (2000 Wp). Because of the double-coat of the absorber the power gains 20% more with the reflector. Reflectors will be delivered optional. A white wall or a zinc-roof reflects the heat and gives rise to more power. For the OEM-customers it is possible to get further versions of the collector with different quantities of tubes. All collectors from 5 to 30 tubes (step-by-step) with or without reflector are certificated with Solar-Keymark.

        The advantage of our solar collectors in a summary:
        • Single vacuum tubes with plug-in connection that can be easily exchanged (registered for patent!)
        • Tubes which can be rotated 360° and aligned to the sun! Based on this technology, all types of assembly are possible without sub construction! E.g. Facade installation: 45° south or 60° south absorber optimisation adjustable by rotating the tubes (any angles naturally possible).
        • Filling of the system is also possible during strong sun radiation (turn tubes out of the sun’s rays)
        • All collectors are available as CKD-versions (completely knocked down)
        • One-man collectors: Collectors are quickly assembled on the roof! (registered for patent)
        • NARVA-Tubes with double sided coated absorber (higher output)
        • Various collectors connected together always have the same tube spacing! (optical appearance one single collector)
        • all solar collectors are offered as self-supporting constructions - therefore no complicated profile sub construction is necessary !!!
        • AkoTec solar collectors have the zeta-plus seal of approval: This guarantees constant high quality during manufacturing and equal volume flow through every single tube.
