A solar collector is provided that is formed from relatively thin polymer sheet(s). The sheet(s) are welded together to integrally define a storage tank, a plurality of fluid flow channel (e.g. risers), and other desired features within the collector. The storage tank is located at a first end of the panel and a heat exchanger is provided within the storage tank. The heat exchanger is arranged to transfer heat from the storage tank to a target fluid (such as water) that is to be heated or preheated by the collector. The collector is arranged so that when it is installed, the collector may be positioned with the storage tank located generally above the fluid flow channels. The storage tank and the fluid flow channels are arranged such that when the collector is installed and filled with a working fluid, a thermosiphon effect will cause the collection of hot water within the storage tank.
