Solar thermal collectors are almost carbon-free (using power only for pumps and controls). High-temperature collectors make hot water at temperatures suitable for almost any use in a hospital. They must be coupled with storage and another heat source to ensure round-the-clock hot water.

Solar thermal collectors absorb more of the sun's energy and photovoltaic (PV) panels, but the whole system is a bit more complex.

I don't know of any hospitals in the US who have used solar thermal and liked it. I remember talking with people who experimented with systems during the 70s and found the systems did not work well, or took a... (More)
