Our take on the Justdolife 100 Pcs Small Solar Cells, Mini Solar Panels with Monocrystalline Silicon, Optimized Efficiency for DIY Creative Designs, Car Chargers, Portable Power

These are 100 tiny monocrystalline silicon solar cells, each about 2 x 0.75 inches. They are sold as a bulk pack for hobbyists who want to embed solar power into small projects, models, or portable gear. Monocrystalline silicon converts light more efficiently than amorphous cells of the same size, but each panel is small, so output per piece is low. They suit tinkerers and makers, not anyone expecting to charge a phone or run a car charger from one panel.

Questions and answers

Can these charge a phone or run a car charger?
No. Each cell is tiny and the listing gives no wattage, so a single panel cannot charge a phone. You would need many wired together, and even then output is limited.
What voltage and current does each panel produce?
The listing does not state voltage, current or wattage for the cells. Ask the seller for a datasheet before relying on them for a project with specific power needs.
Do I need to solder them?
The panels come as bare cells without stated connectors. Most projects require soldering wires to the terminals or mounting them in a holder you build.
Are they waterproof for outdoor camping use?
The listing does not say they are waterproof or sealed. For camping gear, mount them behind a clear cover or inside a sealed enclosure.
How many do I need for a small project?
It depends on the load. Because per-cell output is low and unspecified, plan to test a few cells with a multimeter and scale up until you reach the voltage and current you need.
Where is the Justdolife 100 Pcs Small Solar Cells, Mini Solar Panels with Monocrystalline Silicon, Optimized Efficiency for DIY Creative Designs, Car Chargers, Portable Power cheapest?
At Walmart, for $13.97, as of our latest check.
