Circuit Project: Solar Panel Voltage Regulator
U1A compares an adjustable sample of the present battery voltage to a 5V reference from a highly stable source. According to the result, it controls the power transistors Q1 and Q2, which shunt off the excess power generation from the panel. A diode (D1) avoids battery voltage to go back to the panel under no-light condition.

An appropriate voltage regulator / limiter for a 5V solar panel for
I''m building a USB solar charger for my tablet, which has so far worked well. I''m using a 5 Volt, 5 watt solar panel (same as this one), which outputs about 4.5V and 0.6A in real use when charging my device, together with a 5.1V, 5w Zener diode (1N5338B) to regulate / limit the voltage, as it goes up to ~7V when not under load, which I presume could damage my tablet.

Solar panel voltage barely higher than battery... How will
Solar panels generally fall into two voltage categories: 12V and 24V. A 12V panel can be connected directly to a 12V battery, and my understanding is that the panel voltage is pulled down to the battery voltage so it does not destroy the battery (18V is too much voltage for charging a 12V battery). The chart you mention is likely the IV curve

MPPT: panel V must exceed bat. V by 5V??
As soon as, you put a load on that Solar Panel the active Vmp minus the 1 volt drop of the MPPT Charge Controller will make the output voltage way too low to do any reasonable charging. It appears that you have confused Voc, with Vmppt. If your Solar Panels have an extremely low ( 16v - 17v ) Voc, then you should really be using PWM, not MPPT.

Confused about 12v to 5v solar project. : r/AskElectronics
What I''ve gathered so far is that to convert this, I''d need a 12v solar panel (I''m looking at a 20w panel), a charge controller to charge a 12v battery. A step down voltage regulator to take the 12v output from the battery down to 5v 3A to actually power the lights off the battery. Couple of things I don''t understand:
