Micro Solar Panels with Wire, 5PCS 5V 200mA Photovoltaic Solar Cells Kit 110mmx60mm / 4.33''x 2.36''

These must be mounted by the user. They also must be soldered together, wires supplied. You must know the difference from series and parallel connections. This will change the output voltage of the connected array. Do not over heat when soldering. The output current is higher than most small panels, so you must have a charge controller to prevent over charging the battery.

I took some measurements in full direct sunlight. Here are the numbers for those who are wondering whether one of these panels would be enough to power your electronics project. I measured 118.6 mA without any load, 52.8 mA with a 100 ohm load, and 99.6 mA with a 47 ohm load.

When I first ordered these solar panels there were 4 types. Five piece without wires and five piece with wires also ten piece without wires and ten piece with wires. When I checked the current description I don’t see the 2 ten piece sets anymore. What happened. If I want to order another set of ten solar panels without wires I won’t be able to. I like the sets I originally ordered. Now I can’t order any more ten piece solar panels without wires.

Used to repair existing garden solar led lights. Test with multimeter first. Otherwise as long as your electrical calculations are correct it’s a great way to make old garden led lights work again. Finish is holding up so far.

I used it for an experiment with laser lights and it was successful!

When using solar, if you connect in series, they should increase voltagewhen connected in parallel, should increase power... as in amps.so when I connect in serious, they should be 5 x 5 volts = 25 volts. nopein parallel, 5 x 200 mA should equal 1.0 A. ... nope. only reaches 700 - 800 mA in direct sunlight, clear sky, in southwest Texas.

Honestly I was impressed. I was getting near 100% of the ratings. Glued a few together and created a parallel array that gives me 2A easy. Hooked up a solar USB charger cable and I just leave it out there recharging my small portable power packs( in a weather proof box) I use them to then charge my USB based devices at home. Not bad at all for cheapo cells! Made for a fun little project. You can get a good usb charger from Voltaic.

the item description states 200mA. The way it's stated is that should be per panel. I've test three so far, including putting two in parallel. They all get about 20-25mA in full sunlight. A pair in parallel got around 50mA in full sunlight. They were able to get the expected 5v in full sun. If the listing meant to say the 10 pack as a parallel set would be needed to get the full 200mA, it should have stated that. I figured 200 was a high amount, but I tried to find anything here to commit to per panel vs per 10 pack and nothing gets there. If that were the case, why not also state 50v @ 20mA?If I'm wrong about this, I'd love to know.So, they work and I like the size and they seem pretty durable. Unfortunately, I had hoped I'd be able to put 2-4 together to run a raspberry pi pico with some additional components (a small motor or two) and I'm not sure that will work. As is, even two in parallel don't provide enough current to run a basic small motor.I bought this set to test out before committing part of my class budget to getting more and now I'm not sure these would be appropriate for the robotics class.I guess I expected magic.
