Frequently asked questions
Can I power an Arduino or ESP32 directly from this panel?
The panel can drive small loads in sunlight, but its output changes with light level. For steady operation, use a solar/USB LiPo charger module with a LiPo battery, as the listing recommends. This smooths out voltage variations caused by clouds, shadows and sunset.
Is the panel suitable for outdoor use?
Yes. The panel has a clear epoxy coating with a hard-board backing and a robust seal, which the listing describes as suitable for outdoor applications.
