Small-scale solar modules

Unique-Bargains supplies five polysilicon panels rated at 0.5 volts and 100 milliwatts each. The cells measure 53 by 18 millimetres with a 2.5 millimetre thickness and weigh 14 grams apiece. They are built to resist snow load and prevent water freezing in the frame.

DIY low-power projects

Hobbyists building solar toys, science experiments or small chargers can wire these modules in series or parallel for the voltage and current they need. Installations that require higher wattage or grid-tie certification should use larger, certified arrays instead.

0.5 volt 100 milliwatt rating

Each panel delivers 0.5 volts at 100 milliwatts under standard test conditions. This single figure determines whether the module can directly power or charge your intended low-power device.

Questions about this item

How much current does each 0.5 V polysilicon panel deliver when it runs all day in sunlight?

Each panel is rated at 100 mA at 0.5 V, so under full sun it supplies that current continuously with no moving parts or fan noise.

What extra parts do I need to charge a phone or run a low-power device with these modules?

You must add a charge controller or boost converter, wiring, and a battery or USB regulator because the panels only output 0.5 V at 100 mA each.

Can I wire these 53 × 18 mm panels alongside an older 5 V solar charger I already own?

Yes, but you cannot connect them directly in parallel; the 0.5 V output must go through its own regulator before joining the 5 V system.
