Pros & Cons
Pros
The panel fits well on a bicycle where you may need portable power. I have this paired with a simple mppt charge controller. I have it connected to a solar charge controller then to my atv battery.
I am sure to get 15 w or more outta this 25w panel at all times based on the load. Very well for its size and amp/volts it produces.
Cons
These photovoltaic panels are not 25w as advertised. When i hook this up in full sunlight, the voltage on the panel drops down from 19v to 5v, and it barely puts out 800ma. I use a voltage regulator, but this is not what was advertised.
Junction box has no wires and no screw-terminals. Nowhere to be shown is who not even on the box. Voltage is weak and unstable. Connectors are very fragile and break easily.
Highlights
Quality
Overall this product works well for the price and is a power generating solar panel that i used to operate my automatic chicken coop door
Good panel for the price quality is good use it to power led lights
I’ve already pulled 110 watts out of it with the sun low in the winter sky
Price
The price was a lot better then the 5 wat one from mighty mule for my gate opener
Competitiveness
This is the best value panel but is likely 1020 more expensivew than the current 100w monocrystalline panels
Im using it in conjunction with a werchtay 30a mppt solar charger and it keeps my trailer batter and all my toys charged at around 14
I drained a roypow lifep04 battery to under 50 to avoid any current limiting from the rich solar mppt 20a charge controller
9tishi hery monocrystalline portable 120w measured 86

It did not require a solar voltage controller for it

The current wiring does not specify what gauge wire it is on the casing so i took a guess at 16 guage

I picked these up to help winter solar production these are set vertically to the south and when the sun is out they produce a ton of power cloudy they don’t do much at their orientation
