Qinghai road lights off-grid photovoltaic energy system how to solve the rainy day

Solar street light is the sun as a source of energy, and solar street light or an automatic lighting control system, as long as you set the working mode of the system will automatically run to work. Now the solar street light is in People's Daily life



the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 In the sun as a source of energy, at the same time, automatic control or a solar street lamps lighting the work system, as long as the set working mode of the system will automatically run to work. Now the solar street light is the ideal road lighting equipment in people daily life, and with the continuous improvement of people's living standard and the continuous development of social production, solar street lights will be used widely, in order to people effectively lighting provides more useful. Then what on earth will be able to use solar street lights in rainy day how long? In fact if the battery solar street lamps 【 Solar street light battery is a battery in the application of solar street lights, solar street light battery is used to produce solar cell components of electricity storage, when light is insufficient or another new energy street lamp, night lighting. 。 。 】 Full of words, is commonly used in rainy day in can maintain the use of seven days. Solar street light solid or not, basically see your design whether reasonable, first of all to the reference area of solar radiation, such as a region 【 A region' Paraphrase 】 Specifically: local regional level, or the level of land. 】 , the most abundant region for China's solar energy resources, total annual solar radiation [ Total solar radiation level refers to the specific time the cumulative value of solar radiation on the commonly used statistics went unquestioned, total amount of month, year total. 】

6680 ~ 8400 MJ / ㎡, the equivalent of 5 doses. 1 ~ 6. 4KWh/㎡。 These areas include northern northern ningxia, gansu, xinjiang, the eastern and western qinghai and Tibet in the west. And five kinds of region mainly consists of two provinces of sichuan, guizhou

, is China's solar energy resources with the least area, total annual solar radiation from 3350 to 4200

MJ / ㎡, equivalent to a daily dose as long as 2. 5 to 3. 2KWh/㎡。 Solar radiation data can be obtained from weather stations at the county level, can also be obtained from the national weather service. The data obtained from the weather bureau is horizontal plane

radiation data, include: surface total radiation and horizontal direct radiation and scatter radiation level. The different areas of the visible solar energy difference is very big, random imitation design created a shortage of supply, lead to solar street light rain

days standby time is short, but not solid. Mainly because of the solar street light is depend on the sun's radiant energy into electric energy to use, but if the continuous appear a few rainy weather? Solar street lamps can also be used? If encounter in recent days the weather is not

good, and it's cloudy or rain, that also don't need to worry about, because we spectrum solar street lamps manufacturer in the design of solar lighting solutions has been considered, rainy day working days is determined by the customer,

I will according to the requirements of the customer put forward finally, to design the solar street lamps to match most configuration scheme. Solar street lamps can be 24 hours a day, according to sky brightness and personal requirements in various environments to automatically adjust the brightness. At the same time the system can also be used for lighting and storage in the distribution of solar battery, however,

after discharge was graded according to the brightness of the light source, to ensure that the whole system in the sunny days full of battery, use LED light source for lighting at the same time, more energy saving province electricity, can also be in continuous rainy days 7 days provide effective illumination.
