Hello everyone
Im doing this project and I have this 12V solar panel, I need to charge a battery to power an arduino. Do you guys think this tutorial would work? Power ESP32/ESP8266 with Solar Panels and Battery | Random Nerd Tutorials
Thanks.
No. The high solar panel voltage will destroy the TP4056 charger. Obey the component ratings.
You can power an ESP32 or ESP8266 with solar panels and a battery, but you need a few components to make it work. You need a solar panel, a battery, a charge controller, a voltage regulator, and some wires and connectors. The tutorial explains how to connect them and provides some code examples for the ESP32 or ESP8266.
However, if you want to charge an Arduino with a solar panel, you might need a different setup. Arduino boards usually run on 5V, while most solar panels produce 12V or more. You can use a voltage regulator to step down the voltage from the solar panel to 5V, but you also need to consider the current rating of the regulator and the power consumption of the Arduino. Alternatively, you can use a 12V battery and a buck converter to power the Arduino from the battery.
To charge a battery with a solar panel, you need to follow these steps
- Connect the solar panel to the charge controller.
- Make sure that the solar panel is in direct sunlight.
- Allow the solar panel to charge the battery for several hours.
- Disconnect the solar panel from the battery once it is fully charged.
- Enjoy your newly charged battery!
I hope this helps you with your project. If you have any more questions, feel free to ask me.
