![]() Its the ideal point for the solar panel to operate around.Īll of the small DC fans can tolerate a range of voltages - some more than others - but - I would be concerned about trying to run one at a voltage about 16vdc. The 18vdc rating is what is called its "peak power point" where it produces the most power - watts. This also can be easily measured as well.Īs a load is connected to the solar panel the voltage will drop as the current increases. If you look on the specifications it should list a value called "Voltage Open Circuit" which is what it produces without a load in bright sunlight. The solar panel will put out a range of voltages depending on the load and the amount of sunlight. I hope someone can explain this all to me. A lot of the info out there is for 12v fans running on 5w or 10w 12v solar panels. I'm sorry for my ignorance with all this, but i'm reading around and getting mixed messages from a lot of forums. Will running the fan this way destroy it? I have no idea if the fan will simply only draw what voltage it needs, or if it needs to be regulated and if so, how? My worry is that the fan is a DC 12v fan and the solar panel is 18v 36W. do i need to do anything special, or can i simply hook up the fan to the solar panel and it will work. So my question to you guys is, will this work?. then i don't have to worry about batteries. So i thought, why not marry the two together and let it run the fan in the fridge. ![]() I also have a portable 18v 36W solar panel i bought off ebay a while back and actually don't use it for anything. I have a heap of PC 12v fans laying around and thought why not put them to good use. ![]() It works great, however i have heard that adding a DC 12v PC fan to exhaust out heat from the condensor fins can increase its performance dramitically. Ok, so i have a 3-way portable absorption fridge i use on GAS for camping. Ok, i need some intelligent input on this as i have little knowlege on this stuff. ![]()
