Depending on water flow rate, how long it’s run, outdoor temps, intensity of the sun etc. a few stats: frame is made from 1×3.lumber, back is ¼” plywood and glass support “dowels” are 3/8” square. Glass is 28” by 32”.
Metal slats are 1 ½” by 1 ½” Steel Drip-Edge Roof Flashing (sold in 10’ lengths – about $4 each). CPVC pipe is ½”. coupler pieces… 18 tees, 4 elbows and a ½” adapter *w/pvc garden hose adapter at the inlet.

Remember to use ‘CPVC’ pipe cement. Collector can be made with either cpvc or copper. Cpvc is light, strong, and flexible, is rated for hot and cold potable water systems (up to 180F) and has lifespan of 50-75 years. Note: the water won’t get that hot. Even my copper pipe water heaters top out at 175F in the summer temps of 110F.//desertsun02
