And you have to buy a new Solar DC-AC convertor, when the old one fails
after a few years.
Want to estimate the cost, when your original supplier is out of bizness?
My guessimate comes out at 4 to 8000 dollars/euros.
Not to mention, what replacing one or two failing panels costs.
25 years without maintenance costs is quite impossible....
You need panels with the same properties.........

There are now 'microinverters' that only produce about 300 watts and are
easy to replace. You do have about 24 of them per panel. With todays cost
it only takes about 5 years for a payback when you factor in all the tax
breaks in the US.

Again look here for a real user.
