What conditions are required to charge a portable power station with a solar panel?

To ensure stable charging with a solar panel, the following conditions are important:

1. Direct sunlight outdoors
·Solar panels cannot generate enough power indoors or on cloudy days.
·Always place the panel outdoors in direct sunlight, ideally on clear, sunny days.

2. Expose the entire panel surface to sunlight
·Fully unfold the panel and make sure all cells receive direct sunlight without shadows or obstructions.
·Even partial shading can significantly reduce power generation, slow down charging, or prevent charging altogether.
