Understanding the working of an MPPT solar charger
To get maximum current the controller could draw the maximum available current, but then the solar panel voltage would drop to 0 and the power would be 0. There is an optimum point where the amount of current the controller draws from the solar panel is just right to maximise the power drawn from the solar panel (current times voltage).

A PV Panel is a Constant Current Source?
If you look at the chart, you''ll see the maximum power point at the ''knee'' of the curve. If you look to the left of there, you''ll see the current stays constant at just under 2.7 amps as the voltage decreases from about 16 volts down to zero volts. That portion is essentially constant current (the current changes a very small amount, but not much).

Combined with the output power, the power of the solar panel must be more than double of the output power. And it needs to be more than 10 mW in this system. A 15×15 solar panel is used in this system. Actually, the average output power of a 15×15 solar panel should be much more than 6.6 mW. The V-P curve of the solar panel under different ...
Can I indefinitely "trickle" charge NiMH batteries with a constant current?
NiMH batteries are generally charged with a constant current charger that stops charging at some point based on one or more of various criteria (time, voltage, -ΔV, temperature, ΔT/Δt, etc.). Here I am asking about continuous charging with no definite endpoint (e.g., applying charging current for days or weeks at a time).
circuit design
This way, the "constant current - constant voltage" charging algorithm transforms into "limited current - limited voltage" charging. Batteries are generally OK with this, as long as your BMS behaves. The load will subtract from the available charging current and it is up to you to get large enough solar panel if you want the batteries to be ...
