Updated review good for solar panels

That's crap, don't buy it. First the USB/power connector on the panel fell off due to heating in the sun. Secondly it doesn't charge anything at all, I tried 2 different batteries and although it says it outputs 12 volts to the battery it doesn't charge it at all. waste of money .

Pros
  • hands-free
Cons
  • little things

Far from 25 watts!

At best I only get 0.25 amps when this panel is 14.4 volts. That's a total output power of 3.6 W! Far from the declared 25 watts. In addition, the charge controller does not drop to the set float charge level, and the solar panel cannot be waterproofed with open USB ports on the back.

Pros
  • The best in its niche
Cons
  • Almost everything is fine

Poor quality control Item

I should have read the reviews on this product before buying. Yes the wiring and connectors are similar to the kit but the main issue was that the voltage from the solar panel was only 4.3vdc in full sun. Of course, given that I used a 12V battery, this was useless. There may be an error in the terminal block, which has a male output and a USB output. In any case, 4.3V will not charge an iPhone etc. and certainly not a 12V battery.

Pros
  • Certified
Cons
  • Available in white only

That's probably good, but the product is clearly of poor quality.

The laminate is full of blisters and I'm sure the power output, which is already low in the spec, is questionable. The associated connectors are of poor quality and poorly assembled. The delivery was delayed and I wasn't allowed to stop the order. This is nothing you should consider more than an experiment. I was expecting to use this to maintain battery charge on farm machinery. I don't intend to use it for anything at the moment.

Pros
  • Ideal for outdoor activities
Cons
  • Quality

Stack of Parts

This product confuses me a little. They contain a charge controller, but there is no (direct) way to connect the panel to the controller. There is only one DC/Barrel (and USB) jack on the panel. Two connectors included: pin stem to banana clips and pin stem to cigarette lighter plug. The charge controller only has bare wire inputs. Like it's an afterthought and they expect you to just connect the panel directly to the battery? In any case. I cut off the end of the cigarette lighter and connect…

Pros
  • Patio, Lawn & Garden
Cons
  • Useless Features

Best Power and Voltage in Solar Panels

Just like I have seen most flexible solar panels, the power rating is rated from open circuit voltage to full circuit. Что да, это ячейка мощностью 50 Вт, если вы измеряете ее таким образом, но это больше похоже на полезную мощность 25 Вт, поэтому мне нужно было купить две из них, чтобы выполнить задачу, которую мне нужно было выполнить, и для места, которое I have. I attached them to the sun visor of the car. In full sunlight I get about 2A at 18V from each cell. And I live in Florida where I…

  • Solar and Wind Power
