DIY YOUR PROJACT
Increase current or voltage by connecting multiple solar panels in series or parallel
How to choose solar panels to power equipment?
First confirm the power, voltage and current of the equipment to be driven. When confirming whether the power parameters of the solar panel match the power parameters of the equipment, try to choose a solar panel that is more than 30% larger, and the effect will be better.

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 bought this pack for use with an electronic kit I’m using to lean about electrical engineering. I like that it has been prewired. Saves me having to solder. I tested them with my multimeter, and they are definitely working well.

I purchased this group of five for some LoRa kits. In direct perpendicular sunlight (in Southern AZ on a cloudless day), under load, the five panels produced 4.31V, 4.28V, 4.28V, 4.27V and 4.18V, which is just a tad low to run a 5V USB charger, but worked nonetheless. They are rated for 200 mA. I saw 155-171mA under very good conditions. Still a good price if you know what to expect. I particularly like how the manufacturer left the bus bars open on the back so you can solder to them at various points to keep wire runs short.Would purchase again.

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.

Panel is working well. I put my device up 3 months ago and left it alone and it's still at 90% battery even though it has been a stormy winter.

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.

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.
