Hi everyone!
This is my project that utilizes BQ24074 battery charger in conjunction with any 6V solar panel allowing charge currents of up to 1.5A and automatic PowerPath management and switchover from battery to solar panel and back. It's very simple yet quite satisfying, more details here. It's tested, completed and is working fine at my home, providing me with night LED lights

Thanks!
