Solar charging of meshtastic devices
After messing about with solar panels and lead acid battery charging for a arduino project in the UK. I managed to easily keep it all running on a 15W solar panel. Lessons learnt however is to get the most from the battery it is better to charge a 12v battery and use a step down buck converter for a 5v project, because from 13.6v to 11.2v is the useable stored

Pitfalls in charging a supercapacitor from a small solar panel
I want to use small solar panels to charge a supercapacitor, and the cap then serves as an energy reservoir in the absence of full sunlight. I have already set up a basic circuit with a EDLC supercap (VINAtech, 100F, 3V), a small solar panel (3V, 270mA) and a 1N4001 diode.

How to build a 3v solar charged bank to replace 2 AA batteries
The problem with solar panels is that their output voltage varies widely throughout the day. A simple solution will only charge during peak insolation. The charge circuit must be matched to the battery chemistry. A solar charge controller is designed to handle that variation. Unfortunately, most are designed for a minimum battery voltage of 12V.

6 FAQs about [Solar charging 3v]
How many volts can a solar charger produce?
This must be precisely set such that the emitter produces not more than 1.8V with a DC input of above 3V. The DC input source is a solar panel which may be capable of producing an excess of 3V during optimal sunlight, and allow the charger to charge the battery with a maximum of 1.8V output.
What is a simple solar charger circuit?
Simple solar charger circuits are small devices which allow you to charge a battery quickly and cheaply, through solar panels. A simple solar charger circuit must have 3 basic features built-in: It should be low cost. Layman friendly, and easy to build. Must be efficient enough to satisfy the fundamental battery charging needs.
How does a solar cell charge a 1.2V battery?
Below is the circuit diagram for it. The solar cells positive terminal is connected through the diode to the positive terminal of the 1.2V battery. If the voltage of the solar cell drops below 1.4 volts then with the 0.2V the blocking diode takes there wont be enough potential to charge the 1.2V battery.
How do you charge a solar panel battery?
In such situations the battery might need an external charging from mains using a 24V, power supply applied across the solar panel supply lines, across the cathode of D1 and ground. The current from this supply could be specified at around 20% of battery AH, and the battery may be charged until both the LEDs stop glowing.
What happens if a 4.5V / 3.3V Charger draws current?
Power Path to Load - If the 4.5V or 3.3V load connector is drawing current while the USB / DC/Solar power is attached, it will default to drawing current from the charger and any left over current will go to the battery. That keeps your battery from constantly charging/discharging which will reduce the battery life.
Can a solar panel charge a battery directly?
For example, if the open circuit voltage of your solar panel is 20V and the battery to be charged is rated at 12V, and if you connect the two directly would cause the panel voltage to drop to the battery voltage, which would make things too inefficient.
