При большом количестве солнечного света я только что протестировал эту солнечную панель. Без нагрузки он выдает около 14 вольт. Затем я подключаюсь к двигателю постоянного тока 12 В, пока измеряю ток. Когда я пытаюсь остановить двигатель, он останавливается примерно на 0,15 ампер. Это означает, что минимум 12 В * 0,15 А = ~ 1,8 Вт. Вот почему я оцениваю низкое соотношение цены и качества, поскольку выходная мощность составляет 10% от того, что они говорят.
