Hello everyone, Firstly thank you for taking the time to read this! I am a complete electrics beginner, so forgive anything stupid I say. I'm also typing this on a phone, so sorry for the odd nonsensical word! So here is what I am trying to do: I have a small greenhouse, the plastic kind. I live in the UK, and the weather is pretty unpredictable. When its sunny and I'm not home to open up the flap my greenhouse steams up, which isn't good for the plants. I want to make a small fan, that sits in a hole in the plastic to act as an extractor to ventilate, but only when it's sunny. I bought a solar light and took it apart, connected it directly (no battery) to a 12v laptop fan. In direct Sun there wasn't enough power to start it moving, but enough to keep it spinning if I started it off manually. So I tried connecting another panel. I tried it in series and paralel circuit, and just got the same outcome. I have just bought a more lightweight fan, that is only 5v. I connected the two panels in the same way, but can't get it to do anything. Tried series and paralel, nada. Hooked it up to two AA batteries just to test it works, which it does. I believe the panels are 2v each, it doesn't say on them, but I have found very similar one a online that are 2v. I have so far spent only about £6 on this, it's not worth spending lots of money on. So I'm open to any and all bodging suggestions! Thank you for your help!
