So i have been doing my homework before i build my solar system and am curious why i have not come across this.
2 inch piping is much "better" than 1.5 inch, but in the situation you have multiple solar panels hooked up, and these panels have 1.5 inch diameter headers, then this would be a major innefficiency in the water flow. Therefore, instead of hooking up two solar panels together and having one 2 inch pipe connect to the 1.5 inch header of the first solar panel (out of two panels). Why not have the 2 inch pipe flow to EACH 1.5inch solar panel separately. See diagram below. I just have not seen this done or in the solar instructions but maybe i missed it.
Flow rate should also be slower I think with this design
thanks!
