Hello, this is dong sourcing agent in China, top 10 China sourcing agent, can help you sourcing products in China, we have more than a thousand excellent products manufacturers and suppliers, can provide you with high quality export products.
For example, it is estimated that certain types of goods will increase prices, prior to a large number of purchases, in order to reduce the cost of imports, to strengthen the competitive behavior of goods procurement behavior. The use of speculative procuremen
t also depends on the current situation does not apply, usually in three cases, we can use speculative procurement, a), the price of goods bullish; b), the expected source of shortages; c), financially strong business. Use this way to purchase, if the speculation is successful, can get high profits, short-term returns significantly, but this method has considerable risk, there is no certain capacity of enterprises do not recommend this approach. 6, budget p
rocurement Budget procurement is planned after the plan in a fixed time to step by step procurement. Most of the large and medium-sized stores use this approach to purchase. The same time as Budget procurement, relatively stable, both to avoid buying and selling is likely to appear temporary purchase of procurement situation, but also to avoid the risk of speculative procurement, but this method is lack of flexibility. Product procurement management system General rule 1.1 To standardize the company's business procurement work, specially formulated this system. 1.2 This system applies to the company's business procurement activities. 2. Purchasing principles 2.1. Strictly enforce the inquiry price procedures Items, materials procurement must have three suppliers to provide quotes, in weighing the quality, price, delivery time, after-sales service, credit, customer base and other factors on the basis of a comprehensive assessment, and further agreed with the supplier the final price. Except for temporary emergency purchases. The contents of the quotation should cover the company profile, company name, brand name, product style, unit, unit quotation, contact person and telephone number, the factory site, the best stamp company. 2.2. Procurement review
, the contract will sign the system Item procurement must go through the logistics, finance, procurement departments to participate in, and research summary of the views of the parties, the general manager of the audit. 2.3. Separation of duties Purchasers are not allowed to participate in the acceptance of goods and services. The same time as Procurement of goods quality, quantity, delivery and other issues to be resolved by the logistics department in accordance with the contract requirements and the relevant standards and consultation with the supplier to complete.

Through the calculation of Hay model, we can get the monthly mean solar irradiance variation of different inclination planes. In different angles of the inclined surface, the amount of solar radiation vary widely, for the battery panel to choose the right angle so that it can get the maximum amount of solar radiation . In this case, Solar panels are divided into monocrystalline silicon and polycrystalline silicon two, polycrystalline area is larger, the power efficiency is not single crystal high, so according to the need to design 70W monocrystalline silicon solar cell components. 4.3 Batteries Storage battery is a square array of solar energy storage device, its role is to have a square in the sunshine when the excess energy stored in the evening or rainy days for the use of the load. The battery pack is made up of several strings of batteries connected in parallel. General capacity to be able to solar radiation in the days to meet the user requirements of the power supply time and power supply. Currently used in lead-acid batteries, nickel cadmium batteries are also useful occasions, but the price is relatively high, relatively speaking, the former is not widely used. In this case, Battery is a chemical power, it will be converted into DC chemical energy storage. When necessary, then chemical energy into electrical energy released. The energy conversion process is reversible, the former known as the battery charge, which is called the battery discharge. In the photovoltaic power generation system, the battery on the system to produce energy storage and regulation play a role. Since the power output of the PV system is changing every day, there is little or no maintenance of the photovoltaic system in the sunshine. The battery can also provide relatively stable power In the photovoltaic power generation system, the battery is in the state of floating charge and discharge, the summer sunshine volume, the square to the battery charging; winter sunshine is small, this part of the stored energy gradually released. On the basis of this seasonal cycle but also with much smaller on the cycle: the day square to the battery charge, the evening load of electricity is all supplied by the battery. So the battery self-discharge to be small, resistant to overcharge and discharge, and charge and discharge efficiency should be high, of course, also consider the low price, ease of use and other factors.
The 21st century will be based on solid-state light-emitting materials as the core, that is, LED as the representative of the new light source, green lighting century. from now on. As governments attach great importance to and increase investment, LED will become the century's highly competitive new green light and set off a new revolution in the field of lighting . In this case, Solar road lights do not need to set up transmission lines or trenching laying of cables, without special management and control, can be installed in the square, parking lots, golf courses, schools, parks, streets and highways and other places. In this case, Road lighting and people's production and life are closely related, with the accelerated process of urbanization in China, green, efficient, long life LED lights gradually into the people's vision. In this case, 2 program demonstration 2.1 Design requirements (1) the calculation and selection of the power of the panel; (2) battery capacity, charge and discharge control and charge and discharge status display; (3) three consecutive days of rainy days can still lighting; (4) light automatically when the lights lit, to save energy 24:00 off, 5 am lights, early On the light when the street lights automatically turn off (switch lights time point adjustable); (5) The system can save the power when the user set the various parameters. In this case, 2.2 program selection Solar street light control circuit with the basic functions of the same basic, are in order to complete the evening lights, the role of lights in the morning, there is the battery charge management. Commonly used controllers at home and abroad have separate light control type, clock controller type, latitude and longitude controller type, etc., but because of its working principle is different, each have advantages and disadvantages. In this case, 2 Individual light control type generally use the sensor, when the night light is weak, automatically open the street; morning light is strong, automatically turn off the lights to achieve the role of automatic control.
