The solar panel automatically reduces voltage after it is fully charged
When the batteries in a solar power system are fully charged, any excess electricity generated by the solar panels is usually sent back into the grid if the system is grid-tied. If the system is not tied to the grid, excess energy production would generally cause the charge controller to cease sending power to the batteries to avoid.

However, if the power generated exceeds the solar battery's capacity, it can overcharge the system. An overcharged solar system can severely damage a battery's life. As soon as a solar battery reaches full charge, the inverter and charge controller must step in to mitigate risks by handling excess power.
What happens if solar batteries are fully charged?
