Review on 🌞 bayite BYT-7A006: Quiet DC 12V Solar Hot Water Heater Circulation Pump with 3M Discharge Head and 2.1GPM Flow Rate by Derrick Shah

[Updated in 8 months] I turned off the pumps (I have 3 of them) for a few months over the winter but drained them plugged in and left exposed to low temperatures. And we had severe frost in February! When I turned the pumps back on in the spring, they resumed their work as before. So the reliability is fine. Now they work on a timer, every day about 8 hours a day. I'm assuming they've already been outside for over 1000 hours (albeit out of direct sunlight). Blackboard. I have water pressure whenever the sun is out and I can use that low pressure to circulate the water to reduce algae growth. And when the hose timer opens, the pump also pushes water through the hose timer more reliably. (Relying on gravity alone to push water through the timer was unreliable.) That is, the pump pushed water up through the 1/4 inch hose into the recirculation tank and down to the irrigation hose timer . through a 1/2" hose. A 1/2" "slotted tee" irrigation riser was an easy addition to the power output of this pump. The pump is rated at 12V, 0.7A, which is 8, Equivalent to 4w so I bought a 10w solar panel In the July Texas sun this solar panel couldn't get the pump to work It looks like the starting current draw for this pump is well over 0.7A lies because it lowered the output voltage of the solar panel from 17v to 6v and the pump just turned on a buzzing noise sound but didn't work doesn't spin when connected to the battery the pump works fine and drains the water bucket so fast, that I can hardly measure the voltages When I started the pump with the battery and then disconnected the battery but left the solar panel connected, the pump kept working but not as fast I didn't measure the current draw but ic h have some doubts about the power rating of this pump and solar panel. I could order a bigger solar panel. , but most likely I'll just run this thing on battery with a timer (so it doesn't run 24/7 and drain the battery) and use the solar panel to charge the battery. This cheap and easy remote watering setup is only going to get more expensive!
