Solara has revised the M series and now offers the solar modules without a frame and for glueing on. In addition, the new generation is said to have seven percent more power. The modules are available in ten power classes between 12 and 150 watts and weigh from 900 grams upwards. The glued-on solar modules are supposed to be walkable and non-slip and can therefore also be glued onto the deck or superstructure – as long as the surface is stable and flat. Since the modules are somewhat flexible, they can adapt to slight curves such as the deck. Solara gives a five-year product guarantee on the modules. The price starts at 289 euros.
