Thanks for info.
I tried but cannot find maximum solar input voltage for YX8018. Do you have this information :)?

1.2 volts
More precisely – I found that this chip reqs 1.25V. 3 subcels (3 strips) work well
It is not max solar input voltage, it is battery used. I tried with 5V and it is still safe
