Interesting place to visit if you are in West Wales for any reason - even the lift from the car park up to the main site is water* operated!
I can remember visiting it back in the 1970s but not in very favourable conditions. It was an overcast day with some drizzle. No direct solar power. There was very little if any wind. The Pelton wheel was broken. The digester had indigestion and was out of order. All in all not a good day for alternative technology.
