You can see from the above analysis, the annual winter solstice is the minimum amount of solar radiation, which is generating the least amount of solar modules, when the annual winter solstice is the shortest day, longest night, when the longest path lighting needs . Currently in the design of solar street everyone concerned that continued rainy-day lighting problem, in fact, this problem is still relatively good deal, just part of the growth capacity of the battery can be, if you want the path of the winter solstice lighting indicators meet the state standards requirements, unless the expense of spring, summer, autumn generation solar modules, no other way. In this case the efficiency of the system will be very low. There are a lot of people do not agree with the above ideas; the reason is very simple: the installation of solar lights, still working after normal before the winter solstice. It really so? In the solar cell power source efficiency is certainly the situation, the use of solar street lights, there are many factors that influence the effect: solar radiation intensity, rationality, the ambient temperature, the battery level of the old and new solar module tilt angle (old and new battery charging and power generation Efficiency can differ by more than 30%) and the like. In these conditions there is no certainty the effect of previously evaluated using solar lights are not correct. (1) "to light" does not mean you can reach the national standard CJJ45-2006. Urban path lighting design requirements of the standard path illumination. Some situations. The output power of the light source can vary with the battery voltage, the lower the voltage, the output power is smaller, the smaller the illuminance. LED light source for solar street light is particularly significant, and its characteristics are licensed to work in a very wide voltage category, but in this situation, the power source is very small, luminous flux drops. This is also one of many people react solar street lighting effect good reasons to use LED manufacturing. (2) charging a new battery, the power generation efficiency can reach 90%. The old battery in the power generation efficiency of 70% or less, the difference between the old and new can reach 20%, and the temperature on the efficiency of the battery is very large. Acceptance of our products, whether it is under what conditions is very worthy of discussion and concern. (3) light-emitting efficiency attenuate, especially LED. Multi Valley photovoltaic solar street light service undertaking multi Valley Optoelectronics spirit of "to provide customers with the most satisfactory products and services" business purpose, multi-Valley Optoelectronics Technology Co., Ltd. solemn promise: to ensure solar lights advanced, reliable, stable at the same time, continue to improve the quality of services, from sale to sale and delivery, commissioning opened, all aspects of equipment maintenance management, technical services, technical training and other users, to ensure that customers get the best service, customer satisfaction, rest assured. 1, to ensure compliance with the packaging equipment moisture, rain, rust, corrosion and vibration requirements, clear identification is correct, so that the safety of goods delivered to the site in a timely manner. 2, high quality, efficient technical services to better ensure the normal operation of equipment, and timely answers to questions raised by users, to help users solve the problem, the company maintenance center and local maintenance network, responsible for the opening of the country, maintenance and technical advisory services. By full-time engineer in charge of the maintenance center ready to provide technical advisory services free of charge. After receiving the failure to ensure that users call, the company rushed to the scene within 24 hours, and solve the problem within 24 hours. The company maintenance center has 24-hour telephone service, full-time engineer accepted by the user, then ensure that users in the use of equipment in the process, timely technical support. Hotline: 0312-313982224 hour telephone: 156308981803, free for users to debug, opened engineer responsible for the installation of field devices, commissioning, open, test. After successful commissioning of equipment, the supplier shall provide a written test results to the user in the user's consent only after the supply-side technical personnel evacuated. 4, regular patrol inspection system I will work for one of the regular maintenance that is organized every six months for the company to run the equipment inspection once. The company mainly engineering and technical personnel inspection, there are designer participation. And listen to the user maintenance staff to reflect problems and suggestions, and constantly improve the software and hardware capabilities and product quality. 5. Warranty Warranty: equipment warranty period under the contract after the successful installation and commissioning of 12 months. Warranty (except for natural disasters and man-made damage) components, component costs, travel expenses borne by the supplier. 6, maintenance of life, to ensure the interests of users and more Valley Optoelectronics Technology Co., Ltd. of solar street since the opening of the acceptance date of the next (excluding natural disasters and human-caused damage) normal condition, said body part (Steel) Warranty two years, the street section 12 month warranty. Warranty period, the company provides life-long paid services. 7, the establishment of user files, improve product quality of the company to carry out maintenance center in addition to outside users technical advisory services, is also responsible for receiving complaints and collect user information consulting, assurance issues and requirements of users can receive timely treatment, and treatment to track and verify . At the same time create a user profile record product usage, provide the basis for future improvements in the quality of the product. We will continue to strive for excellence, to provide customers with the most satisfactory products and services. As a user multi Valley Optoelectronics Technology Co., Ltd., we thank you for your trust my company, my company's products you have any suggestions and requirements shall promptly inform us, but should use the manual and maintenance manual for regular company of various products maintenance, equipment failure shall promptly notify each of the maintenance staff to our company, the timely detection and timely treatment, and to do the daily recording equipment operation station, we believe that through communication and cooperation between the two sides, will maintain good equipment.
