- What can a 0.08W panel actually power?
- Very little: a small LED, a solar toy, or a slow trickle into a coin cell or NiMH battery. It cannot meaningfully charge a phone or run a light for long.
- Can I charge a phone with these?
- No. At 1V and 80mA, two panels together are far below what a phone needs, and the voltage is too low without a boost circuit.
- How do I get a usable voltage?
- Wire several panels in series to add voltage, or in parallel to add current. Two panels in series give about 2V at 80mA in good sun.
- What is in the box?
- Two solar panels. Wiring, diodes, a charge controller and mounting hardware are not included.
- Are these good for a school project?
- Yes, they suit demos of series and parallel wiring and simple solar circuits. Expect output to drop sharply in shade or indoors.
