The MPPT takes the panel voltage and converts it to a charging voltage which is higher than battery voltage in order to get current to flow into the battery, the voltage is reduced, the current goes up, and the power remains the same.

Today, most panels are at least 20% efficient, but the best ones convert over 22% of the sun's energy into electricity. After reviewing hundreds of solar panel models, we found five brands that lead the pack: CW Energy, Maxeon, Qcells, SEG Solar, Silfab, and CertainTeed.
