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:What are the components of the solar street light
Solar street light system consists of LED light source (including drive), solar panels, batteries (including battery incubator), solar street light controller, street lamp poles (including basic) and auxiliary materials and other parts of the composition
Q:The working principle of solar lamps
The use of photovoltaic effect of the principle of solar solar panels solar solar panels to receive solar radiation and converted into electrical energy output, through the charge and discharge controller stored in the battery, the night when the illumination gradually reduced to 10lux or so, the solar panel open circuit voltage 4.5V
Q:The development trend of solar lights
For the market, accelerate the development of the solar cell industry will be promising.
Q:What are the problems of LED solar lights such as high damage rate and low brightness
 Even if 10000 yuan, the difference is the middle of the $8000, and this can be given to the light of the number of points for 8000 minutes? You can count it, personally feel that solar energy is not practical, can only stay in the water heater industry,
Q:Introduction of solar lights is
Solar batteries, and now the type of solar cell-free maintenance of colloidal batteries, lead-acid batteries and lithium batteries, the battery I generally recommend the use of lithium batteries, high charge and discharge depth, long life, light weight, small size, like a lot of solar lights, solar One light is the use of lithium batteries. Such as Blu-ray solar home solar wall lamp, solar garden lights are used in lithium batteries
Q:The advantages of solar garden lights
To solar energy as energy, do not need to pay electricity; do not need to pull the line, the installation is very convenient.
Q:Solar lights do not always open but charge every day, the battery will be bad
Open circuit voltage of about 4.5V, charge and discharge controller to detect this voltage after the action, the battery discharge to the lamp.
Q:How long can a solar street light be used?
Solar street lamp life is also necessary maintenance, in the early installation, we must strictly in accordance with the construction standards to do, in the configuration as much as possible reasonable configuration, increase the capacity of the battery, thereby extending the life of solar lights.
Q:Can a solar-charged watch be filled with a fluorescent lamp?
In short, the output current when the fluorescent lamp is very small, unless the load current is very small appliances, or nothing meaningful.
