Ainda não usei em uma bateria de 12v porém fiz um teste em um dia nublado e atingiu cerca de 18v. Quanto a qualidade parece-me de boa qualidade o painel e o controlador mais ou menos. Aguardar uns dias pra realizar o teste real em campo pra vê se dá pra quebrar o galho. Esse kit vai ser meu carregador de celular.

First of all,super fast shipping.Shipped at 3/10 received it today 12/10 with speedex courier here in Greece. Secondly,ok obviously i believe without testing it with a multimeter that it is not a 50watt solar panel.Its surely less than 50w.Also the controller will be less than that stated. The stuff that support the panel could be better since you have to cut the one cabling either the clamps or the car cigarette plug to connect it to the controller. I simply tested it with immediate usb to phone charging and it works. Now to the positive i believe that for the specific value even though the specs are not so high it can support basic needs like battery charging,phone charging and lighting.I made a wooden shed or a cabin and i think that it will serve my primary purposes like lightning,charging a battery that i have,my phone's baterry etc.Also i believe that it is not ip (waterproof certified) since its nowhere mentioned (may not seen it) but as an overall image and simple use i am very satisfied.Obviously if you need a bigger amount of power you just need something bigger.Overall good quality.

I've received the products. seems ok. there is no cable to connect the solar panel with the controller. you have to figure it out yourself. came in the right time to Greece. will measure it and tell more.

package came ripped and tracking doesn't track package progress. panle seem good quilty for the price. Output of 14.7 volts D.C. will maintain a small battery. the charge controller doesn't work with panel with out modification, but will be great if parallel another panel

Škoda, že nie je kábel na prepojenie panela s ovládačom.

I have connected the panels to a 12v 25w bulb. It doesn't work. As far as I can tell this it not 50w panels. Maybe 10w or perhaps 15 watts. I have made a complaint to Banggood. They say that they don't believe me when I tell them that the panels dont bring 50w.
