Review on 25W Bendable Solar Panel for Portable Car Battery Charging with 12V Cigarette Lighter Plug - Lightweight and Flexible Design by Dewitt Graham

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 have very good sunlight. I am using my solar panels to charge two 12V Ion 12V 12EP Lithium Ion batteries. These batteries contain a battery management module. And they work with my portable fridge too. This setup does not charge Li-ion batteries directly, your battery must have a battery management module. I wish these panels were sold without USB ports because they don't look like they do. Re will be very waterproof when it rains. I used duct tape to block them off to allow rainwater to enter the module on the back of the solar panel.
