Diode for a 12 volt 5 watt panel
The other 5 watt solar panel has an installed diode that came with the panel. Charging connections would be for either a Group 34 Yellow Top or a Group 31 AGM. 10 watts is probably not enough for these batteries, probably needs ~25 watt. 10 watts should supply around ~1/2 amp as a trickle charge if there is full sun.
diodes
I have the positive from the solar going through a 1N4007 diode (cathode side toward the battery) then to the positive side of the batteries. I have the negative side going to the negative side of the batteries. I do not want any of the current from the batteries to go back to the solar panel from the batteries at night so I installed the 1N4007.
Simple Solar Garden Light Circuit – With Automatic Cut Off
Therefore, until it is significantly dark or until the solar panel is able to supply at least 0.6 V to the BC547 base, the 2N2222 remains switched off, which in turn causes the LEDs to remain shut off. Once the solar panel voltage drops below 0.6 V, the BC547 transistor slowly starts turning off, causing the 2N2222 to slowly start turning ON.

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.

Solar Power for Arduino/ESP32 : 7 Steps (with Pictures)
During the day, when the sun shines on the solar panel, the current from the solar panel enters the TP4056 and charges the battery, and the output will be fed directly from the solar panel, because with the two diodes the higher voltage is "passed through". In fact, the voltage of the regulator, which is 5v, is higher than the 4.2v of the battery.

5v solar system
Hi all! I''m building a system to run a low powered USB device 24/7 (it draws 1Ah at 5v per day). Originally I was going to use a 6v solar panel -> USB powerbank (with an ''always on'' mode) -> device. However, the 6v panel doesn''t put out enough juice, and larger wattage 6v panels are almost non-existant. I''m trying to
BLOCKING AND BYPASS DIODES IN SOLAR PANELS AND SOLAR …
Bypass diodes are used to reduce the power loss of solar panels'' experience due to shading. Cause current flows from high to low voltage when a solar panel has cells that are partially shaded. The current is then forced through the low voltage shaded cells. This causes the solar panel to heat up and have some power loss.
