I'm in over my head on a DIY project involving electrical terms I don't understand. I want to use a solar panel to power both a water pump and a computer fan, and need to know if this is possible with the components I have, and if possible how can I splice/connect these non-matching wires?
I'm trying to make a version of the swamp cooler described here
. It requires a computer fan to move air and a water pump to move water. This tutorial says to buy a solar-panel-powered water pump and splice the wires from the fan to the wires from the pump, thus powering both electrical devices. I don't know how to splice!
Here's a picture of the devices I acquired.
I'm concerned that I've put money into a solar panel that might not be powerful enough to meet my needs.
Solar panel: Max power 12W, open circuit voltage 21V, short circuit current 0.773A, max power voltage 18V, max power circuit:0.66A; water pump: input DC 4.5-10V; computer fan: DC 12V 3A. I'm worried about the computer fan's amp number being higher than the short circuit current number for the solar panel. But I haven't studied how amps, watts, volts, etc., relate to one another or work since ninth grade, and it's over my head. How can I assess if this panel is powerful enough to powerful enough both devices?
If the panel is powerful enough, how do I splice the wires together safely? Links to online tutorials would be great.
