Wind & Solar Hybrid Street Light

The request of Photovoltaic products is very high. The configuration of solar lamps, the solar panels' installation perspective and the capacity proportion of batteries and the controller's SOC controlling charge is directly related to the system's efficiency and service life ,so it must make the price according to the latitude and longitude where the product used and the power consumption that how many hours per day and how many rainy days can be assured so that to assure the configuration. It is not right that many factories quote you without asking. We Soundsest would configure and quote you according to the latitude where your system played and the power consumption that how many hours per day and how many rainy days can be assured, so that it could meet your system's working requirement, which is the most optimal and economic.

The conditions which must be provided when the solar street light designed：
1. Where the solar street lights use(detailed to the city)how about the solar radiation?
2. The light source optical and the load power.
3. The height of the light pole and the width of the street.
4. How many hours needs the system work?
5. If it is cloudy and rainy day how many days need the system continue to work?

Selection of solar modules
Solar panels is the core of solar power generation system, also is the part of the highest value. Its role is transforming the sun's radiation into electricity, sometimes sent to the battery storage, sometimes promote the load work .The quality and cost of the solar panels will directly determine the quality and cost of the whole system. We choose the imported single (polycrystalline)crystal silicon chip, which conversion efficiency is more than 16%. We packaging solar modules is in strict accordance with international standards of production technology.
The calculation of the solar cell components should take into account many complex factors. Calculating through special software  the features are Most of the data used by the statistics for the previous data, the measurement of the statistical data and the choice of data is very important. Under the environment where the solar components been (the site's location, solar radiation, climate, weather, terrain and surface features, etc.)The solar battery components designed to stress not only economic benefits but also ensure that the high-reliability systems. A specific location of solar radiation energy data is according to the data provided by the Meteorological Station.

Special solar batteries
(1)the selected of batteries there are so many types of batteries to use with solar battery, the maintenance-free lead acid battery is used widely at present In domestic, we use it because of its features that maintenance-free and less environmental pollution, is very suitable for reliable performance of the solar power system, especially unattended workstations and solar energy lights.
(2)Calculation of battery capacity The battery capacity is very important for continue supplying power. Within one year, components' generating capacity is very different in each month. When it is in the month that can't meet the need, as to rely on battery power to supplement; when it is extra, it would storage the power. So the data of components generating capacity 's lack and surplus , is one of the data to determine the battery capacity .Also, the load power used in constitutive rainy days is get from the battery. Therefore, the power consumption in this period is one factor of determining the battery capacity.

The Five Basic Forms of Solar Light Layout

Attentions
 •The installation and maintenance of solar street lamps must be qualified by a corresponding companies  and technical staff
●Do not use the parts without the manufacturer's recommended , or else the system may cause damage or danger
● All the solar lights devices during the installation process should not scratch, butt;
●Do not place inverted the battery in the transport, installation process and humid and the exposure to sunlight;
●Do not short-circuit lines connecting the various (at the negative exposure);
●System Connection order: load - the battery - solar panels；
●System demolition order: battery - solar panels - load。
●Install solar panels must move to south, you'd better use the compass
●All the screws should be tightened, can not be loosened, reliable connectivity ;
●Threads, pay attention the wire connections be not clamping in the joint of the light pole Wire connections, should be firmly connected, and with PVC tape wound.
●DO not Smoking or firing at the installation area, for there is a small amount of hydrogen when the batteries used, it would be an explosion if meets the fire;
●Because of a lighting system is a separate work units, a slight difference in time to tune on/off lights is normal

●Please every six months clean the dust on the battery components, but DO not water rinse bottom-up

Comparison of Spectra
For eyes: at the same illumination, LED street light is 2.5times than sodium lamp.

Spectra-efficiency Function
The retina is the radiation receiver composed by cone cells and rodshaped cells.
Two cells have entirely different nature and functions. The photographic ability of cone cells are poor than the rod-shaped , but they had different feelings to the shade. When bright lighting (daytime), visual (the vision) the cone cells play a role only, when the weak lighting (night), visual (dark vision) mainly plays a role by the rodshaped cells . The human eye spectral response of the different wavelengths of the sensitivity is a function of wavelength, call it spectrum-efficiency function. Experimental surface, do not observe the dark field at the same time, spectral-efficiency function is slightly different. International Commission on Illumination (CIE) determine the spectrum-efficiency function in Figure (a), from the map (一) can be seen that the visual ν (λ) and the dark vision ν '(λ) between the peaks corresponding to different wavelengths, ν (λ) peak in the 555 nm, and ν '(λ) peak in the 507 nm.

For the same spectral distribution, under the conditions of visual and dark vision brightness, there is an obvious difference.In Figure (二), the brightness of LED lights dark vision is 2.35 times than the visual , and the dark vision of sodium lamp brightness is 0.94 times than vision Usually optical measurement equipment to the photographic visual conditions, and the lights is for night lighting (dark visual conditions), so it needs amend the data if use the general illumination subject for test , LED lights that coefficient of 2.35, sodium lamp correction factor for the 0.94. Therefore, under the same conditions of intensity (measured by equipments), LED lights is 2.5 times lighter than the high-pressure sodium lamp. Accordingly, to achieve the same brightness, LED illumination of street lamps only 40 percent of high pressure sodium lamp can be.
