Solar Power for portable Operations

Today I tested the first time my new solar power setup for portable operations. I am using a 60 W PowerFilm foldable solar panel and a 5 A MPPT charge controller for a LiFePo4 4S battery. The whole weight is 1600 g including the 5 m connection cable.

It was cloudy day and the sun was most often covered by clouds. The panel is only exposed to 1/3 up to max. 1/2 to the full sunlight, if it is there.

Using a power analyzer to measure the incoming power and charge.

Using a power analyzer, the data show a 1.4 A peak current and 19 W peak power. I was able to charge 10 Wh in about 2 hours. Next time I will try to get the panel under full illumination in the sun and measure again.

The analyzer shows current, voltage and power and in addition peak values for current and power as well as total energy (power integrated over time) in Wh.
