Now we have finally achieved our goal of using solar energy to power the water pump while using the water collected from the rain. This is a completely green solution where we are not using any resource that is nonrenewable.
Now let us see how everything is finally hooked up :
Solar Panel Wiring on the outside
Using the AC power from the solar power bank to run the water pump
Let us see how the solar power bank is getting charged from the solar panel and hooked to the power outlet outside to power the water pump. The external power outlet should be on a GFCI.
The black and red wires transfer the collected sunlight and bring it down to the basement to the solar battery bank. It converts the photons into energy that can be used to power the water transfer pump.
Solar bank getting charged while also running the pump at the same time
My solar panel is a 100W solar panel and it reaches a charging rate of 90W+. At this rate, I get more energy stored in my power bank than I really need for the rainwater pump. Since I run the water pump once a week for 30 minutes.
Either I would add more rain barrels by daisy chaining them so that I have more rainwater collected or I need to find a better use for the extra solar energy that I am collecting.
