Banggood

With good solar radiation with approx. 120 000 lux I received 13.6 V and 151 mA with a load of 90 ohms. This results in an output power of 2.05 W. With an active area of 0.16 cm × 0.37 cm = 0.06 m2, this results in 34 W / m2. With more sunshine (late afternoon) I got 17.2 V and 190 mA with a load of 90 ohms. This results in an output power of 3.3 W. With an active area of 0.16 cm × 0.37 cm = 0.06 m2, this results in 55 W / m2. The performance achieved (3.3W) is far from the specified performance

These are great and initial tests are proving super efficient. I can get a constant jaw-dropping 19volts (16:00 afternoon). The battery clips are a hazard waiting to happen - throw these away immediately. The glue holding the wires behind the board not heat resistant. Starts melting in the heat after 20 mins - use some hot glue instead. Overall good panels, have since ordered more.

Thank you I received is good item

Thank you good item

very good

Great and fast service, got what Ineed it.

game in , decent quality good

Написано : Мощность: 60W (Max) Рабочее напряжение:18V Ток : 0-800MA Далее закон физики P=U*I Считайте сами какая мощность у Вас получилась )) Естественно ни о какой " зарядке автомобильного аккумулятора" речь идти не может

Ha llegado antes de tiempo y en perfecto estado, por ahora muy contento, espero que haga su función perfectamente que yo creo que si. las especificaciones coinciden con las del anuncio.
