Trying to do a fish tank outside. I’d like to power a large pump rated at 45watts 120volts 1Amp with a solar panel rated at 145 watts 24volts and 5 amps. Is there some way to make that work?
do solar panels give off AC or DC?
I can also use several small 12volt pumps with some smaller solar panels i have which are 9volts each… can that be made to work just as long as i expect retarded performance?

The solar panel delivers DC voltage, and your pump is a standard AC voltage, so no it can’t and won’t work. There are solar powered water pumps that can be sourced from the internet or many garden stores, but they are relatively costly, and they only work when in full, direct sunlight (the problem with all solar electric panels). Even in full, direct sunlight, the angle of the sun varies throughout the middle of the day, and total power varies. I wouldn’t expect the 9V panels you have to “work” as power source to the 12V pumps.
