Any experience with cheap low power solar load controllers?

Any experience with cheap low power solar load controllers? Looking to solar power a small pond pump that's far too far away from mains to get conventional power to. Nothing fancy, just enough power to circulate the water a bit to prevent mosquitoes from forming. I'm thinking that a small 10W 12V pump should be sufficient. So I was thinking about getting a small 20W 12V panel, but I'm a bit concerned that the 12V panels are actually Voc 21V and Vmpp of 17V, so I might be burning up the pump if I direct drive it. I'm also concerned that the large inrush current to get a motor running means you can't actually start the pump without a battery. So enter the charge controller with a small sealed lead-acid battery. There seem to be zillions of these on the market, but it's really hard to tell the difference or what I should be looking for. I'm likely to just run the pump all day during the sun (no need to run it all night). I just need the battery to start the ...

Probably a bad idea: $89 100W solar Panel to Car Jump Starter to 12v Garage Door opener?

Probably a bad idea: $89 100W solar Panel to Car Jump Starter to 12v Garage Door opener? Greetings All, With the $89 100w Solar Panel deal available - I was thinking a cheap, though mostly easier way to get a powered garage door for a remote shed on a property would be to get Solar Panel - have the output go to a Car Jump Starter and connect it Garage Door Opener that can be backup powered by a 12v battery and maybe some Light sensing LED lights around the perimeter of the shed? I was thinking the Car Jumpstarter would have the right electronics to make sure the battery wouldn't be over charged and the lithium batteries should last longer in high temp areas? Would probably be better off with a good 12v SLA battery? This Shed is located in a hot and humid area, SLA car batteries in my area seldom make it past 3-4 years before needing to be replaced... On average, I don't see the garage door being opened more than 2-4x a week.... Thanks! submitted by /u/outsourced_bob [...
