Points of attention? 1 Solar efficiency will be due to winter, cloudy days, haze, rain, snow, dust storms and other bad weather reasons, resulting in a decline in solar charging efficiency, which will affect the solar lamp lighting time. But when the sunny sun shines, the state of the solar light will become better. 2 Install solar panels, which must be installed outdoors, without any shelter, and without any transparent devices such as glass. Do not install solar panel in the room through the window glass, which the solar charging efficiency will be very lower. Try to form a nearly 180°parallel angle with the sky, and strive for the maximum area of contact between the solar panel and the sunlight, so that the solar charging will exert the maximum efficiency. 3 Be sure to keep the connection line correctly and successfully linked, when the light is not bright, you can try to disconnect the cable line, and then re-link, restart the solar light, the solar light will return to normal. 4 And we have greatly improved the packaging quality of products, as far as possible to ensure the safety of future transportation.
