Very good power output. Well over 75% of max power output obtained from two series connected 400W panels in late February, SoCal.
Delivery was quick and panels arrived in good condition.
The panels need to be handled, in particular unfolded, with care. There is the potential to create significant stresses on the two hinges that link each adja cent pair of panels.
Not suitable for use in moderately strong winds if panels are not laid down flat.
As long as the panels are handled properly and windy situations avoided when not lying flat they should have a long lifetime.
