How to choose the right solar street light
Solar street light is a street light that uses solar energy to convert into electric energy for lighting. It integrates two cutting-edge technologies, solar power generation technology and LED lighting technology. It truly achieves "zero carbon and zero emissions". The solar street light system is easy to install and does not need to be laid in advance. Cables can be installed efficiently, quickly and simply in a sunny place, which is a new direction for road lighting in the new era. It is widely used in the construction of new rural villages, urban and rural roads, campus roads, factory roads, etc. Choosing the right and suitable solar street light includes the following elements:
1. Installation and layout of solar street lights:
The installation and layout of solar street lights need to choose the installation and lighting methods according to the width of the road and the proposed lighting requirements. The conventional methods include: single-sided lighting, double-sided symmetrical lighting, and double-sided staggered lighting.
2. The light source selection of solar street lights:
In view of the deteriorating global environment and the continuous warming of the climate, under the promotion of national policies, the most used solar street light source is LED light source.
3 The choice of lamps:
The choice of lamps mainly considers reflectivity, illuminance, and maintenance coefficient. The quality of road lighting can generally be measured by three indicators of road surface brightness, uniformity, and glare. The quality of road lighting is shown in:
1. Brightness level
The average brightness of the road has different brightness requirements according to the road grade. Generally, express roads and main roads require brightness requirements above 2cd/m2, while secondary roads and auxiliary roads or residential roads are relatively low.
2. Average illuminance
Average illuminance refers to the average value of all illuminances on the road surface, which is the unit of illuminating intensity, generally expressed in LM.
3. Glare
Road lighting should strive to limit the uncomfortable glare within a certain range, generally expressed by G value, under normal circumstances, G=7 4. System 4. Configuration calculation:
The formula for calculating peak sunshine hours is: Peak sunshine hours=A/(3.6X365)
4. The determination of the series voltage:
The DC input voltage of the solar street light source is used as the system voltage, generally 12V or 24V. When the solar module voltage is 36V, the battery voltage is required to be no less than 2/3 of the module voltage, so the battery, controller and light source voltage must be selected 24V.
5. The choice of the controller:
The controller is generally made of stainless steel, which is beautiful and durable. The design of the charge and discharge controller takes into account light control, time control, overcharge and overdischarge protection, and can realize secondary energy-saving control, and half-power lighting in the specified period . The battery can be selected as "maintenance-free lead-acid battery", most of which are built into the control box with the charge and discharge controller.
6. Capacity calculation of solar panels:
For solar street lights, the overall system configuration formula: P=light source power X light source working time/peak sunshine hours; where P is the power of the battery module, in W; the light source working time unit is H, and the peak sunshine hour unit is H.
7. Calculation of battery capacity:
The first choice is to determine the type of battery and the number of storage days for the battery according to the local cloudy and rainy weather conditions. There are more cloudy and rainy weather in the south, and the storage weather is generally 5-7 cloudy and rainy days.
Calculation formula of battery capacity: battery capacity = load power X daily working time X storage days ÷ depth of discharge ÷ system voltage
Among them: the unit of battery capacity is AH; the unit of load power is W; the unit of daily working hours is H; the unit of storage days is D; the depth of discharge is generally about 0.8, and the unit of system voltage is V;
8. Light pole design:
The commonly used pole design for solar street lights is a steel tapered pole, which is beautiful, sturdy, durable, simple in processing technology, high in mechanical strength, and easy to make various shapes. The cross-sections of commonly used light poles are round, hexagonal, octagonal, etc., the taper is 1:90, 1:100, and the wall thickness depends on the force of the light pole, generally 3-5mm
9.inclination design:
In order to maximize the solar radiation energy received by solar street light battery modules in a year, we must choose an appropriate angle according to the local sunshine conditions and maximize the exposure time.
10. Wind resistance: In the solar street lamp series, a very important issue in structural design is the design of wind resistance. The wind resistance design is mainly divided into two parts: the wind resistance of the battery module bracket and the wind resistance of the light pole;
