Both regulators will help the solar panel charge your six-volt battery and do that safely. Another consideration for charging batteries with a solar panel is a battery backup bank. While charging a single battery, you can also charge a battery bank. The energy in the bank will allow you to charge your devices when the solar panel is inactive.
You need to place the panel in direct sunlight for some time to charge the battery with solar energy. Q. What are the devices a 5-volt solar system can power? It is suitable to power IoT devices, laptops, mobile phones, Alexa, and security cameras.
This option charges the battery much better, because the solar panel is much more efficient at voltages below 5V than it is above 5V, and even at 3V, the battery was charged at around 150mA, and as the battery voltage increases the amount of power (voltage x current) being put into the battery increases. e.g. 3V @ 150mA = 0.45W 4V @ 150mA = 0.6W
You need around 360 watts of solar panels to charge a 12V 100ah Lithium (LiFePO4) battery from 100% depth of discharge in 4 peak sun hours with an MPPT charge controller. What Size Solar Panel To Charge 50Ah Battery?
Although it’s slightly costlier than an electric power bank, it’s worth the price From the above points, it is evident that a 5-volt solar panel is quite helpful despite its low output voltage. However, if you want to know the differences between a 24-volt and 5V solar panel, you must read the following table:
You need around 180 watts of solar panels to charge a 12V 50ah Lithium (LiFePO4) battery from 100% depth of discharge in 4 peak sun hours with an MPPT charge controller. Related Post: How Long Will A 50Ah Battery Last?
4.5volt open solar voltage, -0.2v diode = 4.3volt on the battery. That will even overcharge a full LiPo, if the panel would produce current at that voltage. At the MPP of 3.4volt, only a flat battery would receive all the power from the solar. But this is all theory. I assume you have a DMM with voltage AND current.

If I hook up the first solar panel to the 3.7v battery, it would need to be above 4 volts to charge up, which is a lot of sun exposure. The second solar panel would not need the full sun (I think). Even at 5 volts and around 70mAh which is about half the sun needed, could input voltage to the battery.

I''m trying to build a small transmitter that is powered by a 3.7 volt battery and also a solar cell to run the electronics in daytime and charge the battery. I have almost no experiance in this so am looking for some advice, I have a 6volt 3.5watt 6oomah cell …
My advice would be to buy a TP4056 module and a third cheap 5v panel. Put the three panels in series on input of TP 4056 module for a 4-6V input (will happily drop to around this level under load). You can charge for maybe 3 hours at a time. I wouldn''t recommend charging a Li-Ion battery too much longer than that.
Hi there. I''m a bit confused by this. I have read on a couple of other websites that you can''t hookup a solar panel and battery with a load such as arduino this way as the TP4056 will continue to try and charge the battery due to the TP4506 not being able to detect when the CC has fallen below the C/10 threshold.
In my previous post, I reviewed some "5V 1W" solar panels, with a view to using them to power some IoT devices, and in this post I''ll show my experiments and conclusions about using the panel to charge the battery.
