Has anyone tried to build their own solar panel yet?
The copper panel can be made with 78 OD copper tubing soldered to a 114 header, top and bottom . A 1 T at the bottom for inlet glycol supply and a 1 T at the top for hydronic return .This way you can use one pan-ell or a series of panel ls in a row . Soldered to flat 1|8 thick flat copper . You need a frame and room for expansion . The glass is the problem .Solar glass is Prism shaped and can not be cut .The slightest crack will make the whole sheet Shatter .
