Typically, a 10W solar panel can charge a 6V, 7Ah battery in approximately 6-10 hours of good sunlight. However, cloudy weather or shorter daylight hours can extend this time considerably. I read online saying that to charge, I need at least 10% of the battery current which is 0. Is this right? edit I had gotten a 12V. . The size of the solar panel required to charge a 6V battery depends on several factors, including the battery's capacity, the charging time, the solar panel's efficiency, and the average amount of sunlight available. I've done some research on this topic, but a) could not find any suitable commercially available circuits that I can just buy, b) did not find any tutorials how to DIY such a boost charger myself. Larger capacity allows you to power devices for longer periods.
