That was way back in 2008! Solar has been in China for a long time, but they were using it directly to warm the water, not via photovalic panels (which is why the results were so bad).
- insane_dreamer 3mo agowell, whatdoyouknow, maybe our apartment's water was indeed heated by solar and I just had no idea :)
- seanmcdirmid 3mo agoIt’s hard to say. If they use photvalic instead of pure solar, they can top off a lack of sun with electricity from other sources to keep the hot water warm (outside of winter when it’s all natural gas based anyways). Ome would think they could do a better job with personal heat pumps.
