1.How is the effect of the PIR motion sensor?

The light will be in the energy saving mode when it is dark automatically, light will be off when it is dawn. With this characteristic, the light can be used as signal light, indicator light and continuous light.


2.What to do with the continuous rainy days?

Although solar light is charged by the sun, our product can work when the battery has electric power storage. We have considered the problem and many new products increase battery capacity, which can store enough power when the sunshine inadequate in case if continuous rainy days. The battery can support about 3 nights after fully charged. You don’t need to worry about the safety for there is overcharge protection for the core circuit board.


3.What to do with the rainy day?

Solar light is an outdoor lamp with the waterproof level of IP65. You don’t need to worry about the rainy day.

Q:What is good for solar lights?
Look at the installation height, 6 meters can be the use of human resources, generally 3-4 adults can stand up. Solar street lamps are generally installed in rural areas, large span, not suitable for crane installation. We usually install about 25 sets a day.
Q:What are the parts of the solar lamp
Regardless of the size of the solar fixture, a well-behaved charge-discharge controller is essential. In order to extend the battery life, it must be its charge and discharge conditions to be limited to prevent the battery overcharge and deep charge. In the larger temperature difference, the qualified controller should also have the temperature compensation function. At the same time solar controller should have both street lamp control function, with light control, time control function, and should have a night automatically cut off the load function, to facilitate rainy days to extend the street lamp working hours.
Q:How to determine the power of solar panels solar panels that the number of w
battery life should also be considered in the entire street lamp system applications, the general battery warranty for three years or five years, the general power storage after six months there will be dissatisfied with the situation, some of the actual charge rate may drop to 50% , Which will affect the continuous rainy days of the night to choose a better battery is particularly important.
Q:The working principle of solar lamps
Aluminum alloy lamp column is made of aluminum alloy, belong to the metal material, so the correct statement; B. nitrogen chemical nature is not lively, can be used for protection in the bulb, so the correct statement; C. organic synthesis materials must have three characteristics

The utilization of solar energy itself is not high, only 15%-17%. An ordinary 100WLED street lamp cost even if 2000 yuan, then with the wind and solar complementary system is estimated to be ten thousand yuan. 
Q:The advantages of solar garden lights
Lamp appearance requirements do not be very high, relatively practical on the line.
Q:Can a solar-charged watch be filled with a fluorescent lamp?
Amorphous silicon solar panels in the fluorescent lamp when the best power generation capacity
Q:What is the meaning of the solar controller battery indicator light
On the other hand, the opposite is full. The general voltage is greater than 12V
