What's the flow rate on your pump and what's the flow rate after your solar panels? My pump is rated to 528 gallons/hour, but it falls down to 108 gallons/hour when it pumps the pool water 8 feet up on my flat garage roof and then through 820 feet of ¾ inch PEM hose. My pool contains 3,300 gallons and with this setup, it'll take about 30 hours to run every gallon through the heater and that's a bit rough with 18 hours of daylight. With a flow rate of 1,8 gallons/minute, I'll get an 18°F difference before and after the heater with a clear blue sky. I'm trying out some different solutions as we speak, to increase my flow rate and heat my pool even faster. I'm not going to give up until I get 86°F in the pool around 2:00 PM on a partially cloudy day, then I'll be satisfied. You can see my setup @SolarProjectsSweden I wish you good luck and a warm pool summer
@@thestclairchannel3889 My theory (or dream): 8 gal x 60 min = 480 gal/h. 3,300 gal pool / 480 gal/h ~ 7h. ~70°F pool water in the morning. ~100°F after the heater. Half of the pool water has run through the heater in 3,5h and it should be around ~85°F in the pool at around 2:00 PM. I'm trying to achieve this only using solar DC. My pump is a 20v barrel pump that runs directly of a solar panel. I've tried 3 different solar panels: 50W - 0,7 gal/min 120W - 1,58 gal/min 180W - 1,8 gal/min The results above is through the heater and it's pretty far from the pumps rated 8,8 gal/min, so I'm trying out some different setups to put my theory into practise.
I would restrict the flow with a valve and let the water get hotter longer in the tubes , My dyi black hose heater puts out 110 degrees but at a strong pee rate )
Excellent update - eventually I want to do the same thing. Thank you for documenting

I’m getting 11-12 gal per min off the .5hp pump

Temperature change without flow rate makes it impossible to see the value. It could take an hour or a month to raise the pool temperature by a degree
