For that, you need at least: 12V 60Ah battery (better take 100Ah for safety)
Panel: Minimum 100W panel recommended.
Important:
Cheap 10A PWM controllers are okay for small systems, but MPPT is better (more efficient). If budget is tight, PWM is fine.
And yes — when there is no sunlight, the battery supplies power automatically. That’s how solar systems work.
