I've always wanted to make very low power micros to do simple sensor/comms things in fully autonomous remote locations, but I don't know how to make the solar requirement economical, compared with the cost of the micro.
Is there a _cheap_ way to add solar to very low power boards?
- tyingq 8y agoAliExpress has lots of cheap panels and 5V solar controllers. I suppose the trick is finding one with a credible 3rd party review/how-to.
- icebraining 8y agoSearch for "solar panel usb", you can find 2W models for <$5, or 10W for ~$12. Add a powerbank and you're set.
- jononor 8y agoYou even get cheap powerbanks with solar integrated.
