This is two 6 watt solar panels daisy chained to 12 watts total. It converts down to a little over 5 volts for USB. This powers an ESP32 microcontroller (LilyGo T-Display-S3) which is running a very light bitcoin mining client. The client is not powerful enough to participate in standard pooled mining, but does have an extremely small chance of mining a solo bitcoin block (it has happened a few times prior off lower hash rate devices). All of this here is happening for free with the power of the sun. My next iteration is to add battery charging for overnight mining.
