The solar power panel 120 M excels by highest energy
output and mechanical stability. All this is accomplished by the usage of best
materials and long-time experiences. Every alfasolar 120 M consists of 72 monocrystalline
solar cells. Built between highly diaphanous safety glass and a multilayer tedlar-foil
and embedded in soft EVA-synthetics (Ethylene-Vinyl-Acetate) the cells are protected
even at extreme environmental conditions.
The neatly worked-up concave chamber profile-framework
without any bolted connections plus the preinstalled plug-connectors by Huber&Suhner
allow easy and fast installations. Bypass-diodes minimize the cell-strain in
case of partly shady circumstances. Therefrom the solar power panel can reach
a lifetime of more than 30 years..
The measured data of every panel are displayed
on the provided inspection sheet. This means exactly denoted power for every
panel.
The solar panel alfasolar 120 M is tested and certified
at TÜV Rheinland according to IEC61215 and Safety class II (750 VDC).
