What do you mean by "real price"?

Not understood, if the glass plate and the aluminum frame hold, no problem. We are not talking about the installation system ...

In my previous areas, no problem. Suppliers who have a website also have all the certifications, often German. For the moment, the guarantees that I have seen are 2 years on 100% operation, 10 years at 90% and 25 years at 80%: from the standard, nothing to say in my opinion, especially if we are already making a profit in 3 years...
I prefer to pay off in 3 years and have a short warranty, rather than pay off in 25 years and have to trust a national policy.
A guarantee is an insurance contract and it comes at a cost.
