6. Solar panel on roof

This solar panel collects heat from the sun to heat up water for use in the school. The water passes around pipes in the panel. The panel faces south so it gets the sun all day and it is painted black so it absorbs more heat.

The pipes are insulated so that once the pipes absorb heat, they do not emit it easily. Some panels have a special material over the top that is very good at reflecting back the heat energy so the warm water stays warm and keeps getting warmer.
