With the economy of scales problem, the price must be staggering. Normal rooftop PV is pretty much cost optimized by huge volumes. It is designed to be strong enough to just barely survive the installer carefully stepping on it by maybe half of their weight. Combined with the instructions that say not to step on it this seems to be a good compromise.

Even if one could manufacture a stronger variant where you can walk on on regular basis with maybe just tens of % more materials, the cost will be much more than just tens of % because of NRE cost for niche products.

And/or, it actually does not survive because the engineering was not done to the extent it should have been because it would have been even more expensive.

And it looks like these are well constructed including drains to divert rain water; this design clearly went through a few iterations. So for sure their lifespan is more than a few years. It would be interesting to figure out who is manufacturing the solar modules to get some actual data instead of wild guesses. Platio (for example) gives a 5 year mechanical and a 20 year performance warranty on their solar pavement products.

Does anyone have pictures of any kind of solar pathway or plaza surface that is in reasonable shape after even a year or two?

RJSV:
   Wow, Nctnico !
   I STOPPED reading, instantaneously, when I read your injecting the term:
   CONSPIRACY THEORY.

Please read on:
   My usual is to read all, through to end of responses.   However, don't (you people) realize how stupid, or disingenuous you are, injecting your useful sound-terms, sometimes but not always ridiculous new terms, or sometimes political terminology stolen from what you view as 'opposition'...   Please realize you bring contention to the table, like a little kid.
   We see this, sometimes I wish, in contentious times, for a little more, er, skill in opponents.  But mostly all I see is the (already identified as stupid) attempts to 'smear', along with some word-codes.
   Quote:  "...where's your MATH, you math person...".
   O.K. I twisted your words a bit, sorry.

Response ?
(we maybe need a 'Politics and Green Politics' section here (no).

RJSV:
And, oh yeah;  I just realized, attempt to twist this conversation, by characterizing critics as
   "Needing a TILT, to the system", as being the main flaw, when I don't see any previous argument to that.

Well, solar pavements have been around long enough to collect some data on what works and what doesn't where it comes to wear & tear. Also volumes seem to pick up. According to consumer pricing from Platio, it looks like these modules should be around 80 euro each. I count around 30 tiles so that makes 2400 euro for the solar tiles.
