12v 10w solar panel and 5w computer case fan, will it burnout?
It's a very simple question but one I need a precise answer to and google isn't helping much. If I have a solar panel with an output of 10w at 12v and I connect it directly to a computer case fan that needs only 5w at 12v will the fan burn out or does the wattage even matter? Or does the Voltage matter?
What if the power source provides less wattage than the fan needs?
What if the power source provides less wattage than the fan needs?
Hey Ryudai, that 10 watt panel will run the fan just fine. What will happen over time is the fan will eventually fail, the reason is the power output from the panel will be "unregulated" if you connect it straight to the fan. So as the sun comes up higher, the output voltage for the panel will attempt to reach all the way to its open circuit voltage, which is almost always around 17 or 18 VDC for a 12 volt nominal panel. The fan will end up eating a bit more volts and milliamps than it was designed for. Then as the sun goes down, the voltage will degrade with it, and the fan will run slowly, too slow at least for a while to provide for its own cooling needs.
Real Goods Catalogs actually had sets like this for sale for a while. Lately I've only see the ones for pond aerator pumps. They were actually bilge pumps for a boat, with a solar panel included that was rated for about 130% of the wattae requirements for the pump. The catalog said the pump usually last 1 to 2 years and then burn out, but are easily and inexpensively replaced at a boating supply store for less than $20 USD. That type of computer fan is also very inexpensive and easy to find, I would try Marlin Jones website below for a selection of them.
There are installations at commercial buildings that have fans powered by larger panels, and they use a regulator inbetween them. The regulators alone cost more than maybe a dozen replacement computer fans, so it doesn't make much sense to consider one in this small application. We have two unregulated solar charging kits in our outbuildings, but the panels are 50 to 120 watts each, and they are driving into a set of 220 amp hour golf cart batteries, which are absorbing all the extra energy over time. You could consider this if you want the fan to work anytime, not just when the sun is shining. I'd use a 12 volt 9.5 Amphour sport battery from someplace like Gander Mountain or Cabelas. They cost around $15 or $20, but could easily take what the panel is putting out any day, and provide your little fan with over 24 hours of non stop run time if needed. Just hook the battery and panel in parallel to each other, then put a switch in the line between the battery and the fan. Take care, Rudydoo
