  1. That’s an interesting project. I’m currently in a similar project and I’m not quit sure if the battary comes through the winter, since at that location is no heating (down to -20°C is possible). Have you done any precautions to avoid a breakdown. By the way, a temperature log would be very interesting.

    • No, I have not added any precautions to prevent a breakdown. I’ll notice when the site goes down, although Lithium batteries have a very good low temperature performance characteristic. In my application, the minimum temperature it is likely to see is about 25 degrees Fahrenheit or -4 degrees Celsius. I haven’t experienced any long term problems thus far. I’ll have to consider adding a temperature sensor on this board. I have one in the same location already, but the data is not currently posted to the internet.

  2. This is the best and most perfect DIY on how to run a Raspberry Pi on solar power.
    Thumbs up… Great work!

  3. Hi,

    This is a great article, I plan to follow your article to build my own raspberry pi server powered by solar energy to run a network/servers monitoring application.

    Just wanted to confirm, the parts you listed here are the the most up to date?

    • They were up to date when the article was written. I would encourage everyone trying this project to check for cheaper and better alternatives that may exist now. Good luck!

  4. Hi, thanks for sharing.

    Quite a good set up to do some Bitcoin mining. Plug a couple of USB ASIC Bitcoin miners into the Pi…

  5. Are this battery and solar panel not overkill for a RPi? Especially more recent versions that are more efficient in terms of power usage?

    I am working on a project to build a self contained floating SwimmingPoolPi PC. I am using one of the new Model A+ versions of the Raspberry Pi. This consumes about 100mA when not under load (therefore 0.5W). I will be adding a USB Wifi dongle and there will be a bit of a load on the processor but I still don’t think my power consumption will hit more than 200mA or 1W. So energy usage would be 24 Wh per day or 2Ah (for a 12V battery). Therefore your 20Ah battery would last over 10 days with 0 charge from the solar panels.

    FYI – I will see how it works out but I have ordered 4.5W 15V solar panels to use in my project. I haven’t figured out what batteries to use but I am leaning towards a 4 Amp Hour 12V sealed lead acid battery.

    There is now a product called the MoPi which is useful for applications like this as it will monitor voltage levels and shut down if there is not enough power.

  6. You need to get a monocrystaline panel for the pi. Cost for these are super cheap and will power that even when cloudy as long as the panel sheds the snow you will be good to go.

    • monocrystaline cells have better size/energy coefficient, but polycrystaline cells have better temperature resistance. this means, over time, they are both about the same in terms of cost per watt.
