Study - fixed solar panel fitted to solar inputs of CTEK D250SE

LONG TERM OBSERVATIONS
Long term observations confirm my earlier observations. The setup works well.

DASHCAM BATTERY
In the morning I turn on the overhead PWR switch to charge the dashcam lithium battery. After an hour I turn it off and over the day both batteries go close to 100% on solar alone.

OVERCAST DAYS
If you have 3 or 4 overcast days in a row, you really notice the difference in the battery levels (when I am only doing short local trips). One good sunny day fixes that.

MY SETUP WORKS FOR MY NEEDS
The solar panel and 250SE work very effectively for me, especially if the car is parked up.
