The Wunder ALS from SOLARTECH-UK is a high-performance flat-plate collector which impresses with its high yield values ​​and its longevity. The collector consists of a laser-welded aluminium/copper harp absorber with a low-iron / prismatic glass cover. The housing made of black powder-coated / seawater-proof aluminium with a total of 4 connections.

Due to its harp absorber, it is not possible to construct large systems with minimal pressure losses. The on-roof mounting set consists of two special profile rails made of aluminium. Because of the groove in the lower profile and the tongue on the SOLARTECH-UK ALS collector, the collector is simply placed in the groove of the lower rail. Thus, the modules can be finalized fixation can be positioned. The final fixation takes place with a clamp holder on the upper rail. The clamp holder grips the spring of the collector and fixes it firmly on the aluminium profile.
