For example if you want to charge one LiIon, a 5V 1A solar panel will give you up to 4.2V 1A, but a 12V 500mA panel, although it has the same power on the label, will only give 4.2V 500mA, which is half. And the controller should be comfortable with the input voltage sagging, not reboot or shutdown, etc. | |

Thank you for your detailed comment! I had a feeling that connecting linear charger to solar panel is not going to work well, but most of the projects I saw was designed this way and I thought im missing something :) as The Photon implied in the comment above, solar panel needs dedicated charger and not liner one.
