Alpex has been supplying solar panels for tough Offgrid environments for many years. They know how to make a crystalline solar panel that withstands water and salt on the sea or on the road.
Their panels are built for 12-volt battery systems, with strong aluminum frames to withstand the twisting from road/sea, which crystalline solar cells in contrast to the CIGS solar cells, suffer from.
Energig has had Alpex solar panels on the program for years and we only have good experiences with the panels.
Alpex is an economically attractive solar panel.
