In video #142 we started a journey to power or small devices with solar power. Today, we continue this journey.
We will
- Have a look at the available boards and chips to connect solar panels to batteries
Have a look at the available chips for solar panels chargers
- We will try to classify them according the technology used
- We will have a look at the theory of these chargers
- We will build a setup to compare two devices
-We will do measurements in full sun and with cloudy skies
-We will check if chargers will not discharge the battery
The concentratation is on 6-volt panels and one 3.7 v Lipo battery. This is the most obvious solution to power 3.3 or 5-volt devices
