Pretty standard solar installation of Axitec TopCon modules on a steep tiled roof, using a Novotegra mounting system (side fix with clamps), Kostal G3 inverter (10kW) and Axitec battery (6.7kWh). The tiles were huge, 37 x 48cm with more than 5kg each, with lots of storm clamp attachments to them. We thought at first that we wouldn’t manage getting any work done, but it turned out all fine in the end, with lots of helpers getting the tiles off and back on to the roof for grinding hook trenches (no dust on the roof surface). The complete roof was done in 2 days with a total of 7 people (..maybe 3 working simultaneously..). Quite some modifications to the electrical cabinet needed, from parallel to a cascaded measurement concept. Worked all fine in the end, thanks to everyone helping with the installation!
