DIY Solar Panel
Posted By: Jamie  on 12/14/2006
Interested in installing a solar panel to heat water?

The amount of water which can be directly heated to a 'usable' temperature is fairly small so it is usually better to use the panel to preheat cold water in a separate tank before it is fed to the main hot water tank. The solar storage tank should be about 50 litres per 1 square meter of panel, however this is not very critical. The tank and all interconnection pipework should be well insulated to avoid loss of collected heat. The best position for the panel (UK) is in an unshaded position angled to face just west of south at about 35 degrees to the horizontal. Other orientations between SE and SW and various tilts from 10 to 50 degrees cause only small reductions in the overall energy collected.
