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 internationalstandards 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 batteriesthere 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 capacityThe 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 parts of specialized cable and bolts

The connecting cables of solar modules and the cables between components and the controller are used in

outdoor, directly exposure under the sun, so the DC part of solar street light cables choose the DCEYHR

series of cables that are Oxidation resistance, high temperatures, UV-resistant resistance to ensure the

system security and normal operating within a long time, according to each square wire of the current is 1.5

A to determine how thick wire is needed. The wire ' joint must be firm without loose. The wire joined with the

battery needs specialized joint, attention to anti-corrosion.

All bolts exposed to the outside use stainless steel bolts.

Functions & Features

The Five Basic Forms of Solar Light Layout


23/28

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 () can be seen

that the visual () and the dark vision '() between the peaks corresponding to different wavelengths,

() peak in the 555 nm, and '() peak in the 507 nm.

Experimental surface, do not observe the dark field at the same time, spectral-efficiency function is slightly

different. International Commission on Illumination (CIE) determined the spectrum-efficiency function in

Figure (), from the map (a) can be seen that the visual () and the dark vision '() between the peaks

corresponding to different wavelengths, () peak in the 555 nm, and '() peak in the 507 nm.


26/28

For the same spectral distribution, under the conditions of visual and dark vision brightness, there is an

obvious difference.In Figure (), 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 ofintensity (measured by

equipments), LED lights is 2.5 times lighterthan the high-pressure sodium lamp. Accordingly, to achieve the

samebrightness, LED illumination of street lamps only 40 percent of high pressuresodium lamp can be.
