Short test my Small Solar Panel 10w and check of power from Doctor Watch DC
In this video, I will start a project to use solar energy to power ESP8266 or Arduino devices during the whole year.
We wll answer the following questions:
1. What size the solar panel has to be in order to power our device
2. What size of battery we need to survive times with less or without sun?
