FAQ Section
FAQ Section
Q: Can this 3V solar panel charge a standard battery?
A: Yes, you can use this panel to charge 1.2V NiMH batteries or 3.7V Li-Po batteries, but you will need to connect it through a proper solar charge controller or diode to prevent reverse current.
Q: Is the 110x60mm solar panel waterproof?
A: The epoxy resin surface is water-resistant and handles light splashes or rain perfectly. However, the exposed solder pads on the back should be sealed with silicone or hot glue if left outdoors permanently.
Q: Will this work indoors under artificial light?
A: While it can generate a very small amount of voltage under strong indoor LED or halogen lights, solar panels require direct, natural sunlight to achieve their rated 1W output.
