An example of charging a LiFePO4 8Ah battery with 2 solar panels in parallel ( total area 6.4 dm².. a size like an open dvd-case). The light intensity is measured with GA1A12S202 ( just a rough esitmate ). The approximate conversion of Lux for the SUN is 0.000079 W/dm² per lux. The GA1A12S202 has a dynamic range of 3 to 55,000 lux. Values above 4.35 W/dm² are unreliable.
Note, all measurements are available in Plotly fork and edit
( I leave it to the reader to guess when my Windows decided to take a nap...I've ordered an OpenLog ;-)
