There are two different types: flat plate, where lots of thin tubes carry water through a flat absorber panel, and evacuated tube, where vacuum glass tubes capture the sun’s energy directly. There is little difference in performance between the two but evacuated tube panels do more obviously extrude from the roof.
Menai Bridge
Menai Bridge is a town and also community on the Isle of Anglesey in north-west Wales. It forgets the Menai Strait as well as lies by the Menai Suspension Bridge, constructed in 1826 by Thomas Telford, just over the water from Bangor. With a population of 3,376, it is the fifth largest community on the island. There are several little islands near the community, including Church Island. The Menai Heritage Bridges Exhibit celebrates the world-famous Menai Suspension Bridge, developed by Thomas Telford, as well as the Britannia Bridge, constructed by Robert Stephenson.
