Frequently Asked Questions

Q: What voltage and wattage options are available?
A: Options include 0.2W/4V, 0.3W/5V, 1W/3V, 5W/5V, and 5W/12V — available individually or in multi-packs of 2 or 3.

Q: What can these panels power?
A: Solar garden lights, small fans, water pumps, emergency lights, advertising lights, traffic lights, and other low-power devices rated for 3–12V.

Q: Are they waterproof?
A: Yes — the epoxy coating provides weather resistance for outdoor use, including rain and moisture exposure.

Q: Do they come with cables?
A: Yes — each panel includes a pre-attached lead wire approximately 10–15cm in length.

Q: Can I use these for charging batteries directly?
A: Yes — they are designed for charging 3–12V batteries depending on the variant selected. A charge controller is recommended for larger battery systems.
