Bluenose is right as far the Beneteau cost for these panels. It won't be cheap.
However the installation of it will be much quicker. Except for the sealant joints between the panels and all around the edges, there will not be any joint to pour, which can be a real mess for somebody not used to do this type of work.
Not much sanding also.
To be sure, ask the cost of these panels. We might be surprised !
