Fixed anchors may be welded or bolted, and if the welding operation is carried out in the field. Tangshan solar street lighting systems: system consists of a solar cell module, LED lamp (including lamps), controller (including charger, inverter), gel batteries, the poles (including the battery module bracket) composed of five parts, and traditional different excavating buried battery, watered ground, battery directly into the side poles placed in the land below, install using the piling installation, one day after the site may be installed. The main components of the system as shown above. Tangshan solar street lighting works: the use of solar photo-voltaic effect daytime panels made of the principle to receive solar radiation into electrical energy output, after charge-discharge controller is stored in batteries at night when the solar panels open circuit voltage is less than 4.5V, charge and discharge controller detects the voltage value after the action by the controller setting mode discharges. After the end of battery discharge, charge and discharge controller action, the battery discharge end. Charge controller's main role is to protect the battery. Tangshan solar street lighting design: 1) The solar cell module selection, design example is an example of the present specification example, specific programs see customer quotations. Design requirements (customers): the use of regional Shanghai (block installation environment without buildings, etc.), load input voltage 12V Power 40W, while the number of job every day 10h, to ensure continuous rainy days 3-4 days. ⑴ latitude and longitude: The location can understand and master the local meteorological resources, such as monthly (annual) average solar irradiation, the average air temperature, wind resources, these conditions can be determined according to the local solar energy standard peak hours (h tilt angle and azimuth) and the solar cell module, the calculated peak sunshine hours and approximately 3.8h; ⑵ load on power consumption 33AH ⑶ solar modules for the total charge current 1.05 × 33 ÷ (3.8 × 0.85) = 10A in Here, a minimum of three consecutive days of rainy days design between the three days, 1.05 for the solar cell module integrated system loss coefficient, 0.85 for the battery charging efficiency. Minimum number ⑷ total power of solar modules = 120W, the choice of peak output power 80Wp standard battery components, can guarantee the normal operation of the street lighting system in most cases the year. ⑸ battery 120AH, where 0.9 is the depth of discharge, the battery discharge depth colloid is more than 90%! Tangshan solar street light product parameters: 1. Body material: steel poles for the whole, the whole hot-dip galvanizing / spray 2 solar modules: crystalline silicon 45-90WP (load profile) 3 system voltage: DC 12V, 24V 4 Controller: Tangshan solar street lighting special controller, light control + time control, intelligent control 5 storage batteries: gel battery 12V120Ah (depending on the load configuration) 6 Light source: energy saving high power integrated LED energy saving lamps (according to customer requirements) 7 Protection class: IP65 8 Operating temperature: -30 degrees to 70 degrees, wind power ≥150Km / h 9 Lighting time: 10 hours (can be adjusted according to need) 10 Pole height: 6 meters (according to customer requirements) 11 rain day guarantee: continuous work 4-5 rainy days (regional / seasonal variations are different) (according to customer requirements) of the product without laying underground cables, without having to pay electricity lighting, solar garden lights mainly applied to urban roads, residential square, industrial parks, tourist attractions, parks and green belts and other places of lighting lighting. We produce all products in accordance with the standards strictly enforced material inspection, process inspection, finished product shipment inspection to ensure that customers receive satisfactory products, the company built a set of comprehensive pre-sale service system, all for your the interests, the real one on one service. Tangshan solar street lighting Battery Selection: solar power systems, battery performance directly affects the quality and overall cost and operational life of the system, this solution chosen gel batteries, compared to conventional lead-acid battery, which is designed There are upper and manufacturing processes following salient features: long service life, under normal circumstances, the depth of charge and discharge cycles from 1200 to 2000 times, ordinary lead battery is 300 to 500 times, no memory, environmentally friendly, safe and reliable. High energy density, volume and quality of energy is very high specific energy, double nickel-metal hydride and nickel cadmium batteries more, small size, light weight, small footprint, easy to carry, is the ideal, the new green energy. Tangshan advantages of solar street light: 1) high luminous efficiency, low power consumption, long life, low operating temperature. 2) strong safety and reliability. 3) fast response, unit volume small, green. 4) Under the same brightness, power consumption is one-tenth of incandescent, fluorescent one-third, while life expectancy is 50 times incandescent, fluorescent lamp 20 times, after following the incandescent, fluorescent, gas discharge lamps The fourth generation of lighting products. 5) single high-power ultra-bright LED advent of LED applications across the supreme efficiency lighting market as possible, will be one of the human after Edison invented the incandescent lamp, following the greatest invention. Tangshan solar cell module stand lights: In order for the solar cell module of the received solar radiation in one year as much as possible, we want to choose the best angle for the solar cell module. The lights use areas in Shanghai, according to this design reference data in the literature [1], the selected solar cell module bracket inclination of 34 °. Tangshan solar street light wind-resistant design: in Tangshan solar street lighting system, the structure of a very important issue is the need to wind-resistant design. Wind-resistant design is divided into two blocks, one for battery assembly bracket wind-resistant design, two of the poles of the wind-resistant design. The following analysis were done by more than two. ⑴ wind solar cell module stent design basis of technical parameters of battery components manufacturers information, solar modules can withstand wind pressure of 2700Pa. If the wind factor selected for the 27m / s (equivalent to 10 typhoons), according to the non-sticky fluid mechanics, battery components to withstand wind pressure only 365Pa. Therefore, the component itself is completely withstand 27m / s wind speed and not damaged. Therefore, the design of key components to consider is battery bracket and pole connections. In the design of the cover street lighting system in connection with the design of the poles of the battery module bracket bolts connecting rod fixed. ⑵ street light pole wind-resistant design is mainly based on solar panels tilt and height to calculate the pole bending strength, etc., including bead width and other specific parameters in the detailed design. Tangshan solar street light controller: The main role of solar charge controller is to protect the battery. Basic functions must have overcharge protection, over-discharge protection, light control, time control and anti-reverse, etc., detailed instructions see the controller description.
