This frameless model comes with top of the range Sunpower cells with rear contact and laminated fibreglass – this gives stability despite its low weight (6.5 kg). The EFTE surface with micro-lenses makes the cells less susceptible to dirt and reduces reflection.
The particularly low temperature coefficient and the special circuitry for a high open-circuit voltage enable a higher yield even at high temperatures and low irradiation levels.
The panel is equipped with a 7m (2x4mm2 ) cable in a waterproof junction box.
The panel is semi-flexible, i.e. a deflection of max 2.5% is allowed. Metaphorically speaking, the panel may form a bridge over its total length of 1440 mm, with a maximum height of 36 mm in the middle.
