Chengde is a kind of so-called solar street lights use solar energy as an energy source, it is not conventional electricity restrictions, we do not need to discharge ditch embedding, not consumption of conventional energy. As long as there is sufficient light where you can use. Because the County of Chengde City wide solar street unaffected conventional energy sources, will not pollute the environment, so it has been called green products. Solar street general way, the park's lighting. However, in some less economically developed areas, or in areas lacking conventional energy, solar street Chengde also popular. Because solar lights according to their characteristics to solve the energy problems of these places. In fact, due to the advanced technology matures and ideas, broadly County solar street lights in the developed world has also been very high penetration rate, the use of solar street level is already high. But in our country, or in the initial stage. We look forward to solar street lights in the domestic have a better spread. In fact, solar energy can be so rapidly gaining popularity, in addition to Chengde is solar street lights Ethernet sunlight as an energy source, and because it is compared with ordinary light, there are indeed many incomparable advantages. First, he does not ditching embedding, engineering than smaller, as long as installed on a cement base, and then on the stainless steel screws enough. Also because Chengde solar street exempt electricity, as long as one input can be, no maintenance costs, generally two to three years to recover the investment cost, to receive the benefit. Furthermore it wide County relative to conventional solar street lights, the security is relatively strong, because he is a super low-voltage products, it is more secure. The main part of Chengde solar lights, the service life of solar panels is very long, generally about 25 years, so income is relatively large. Chengde solar street light poles main material configuration parameters for the whole steel structure, the overall hot dip galvanizing / spray treatment system voltage DC 12V-24V Controller Solar lamps dedicated controller, light control + time control, intelligent control (dark light from open, day lighting self-extinguishing) crystalline silicon solar cell module 15-300WP (load profile) energy storage battery fully enclosed maintenance-free gel batteries 12V17Ah-200Ah (depending on the load configuration) the type of energy-saving high-power integrated light source LED, energy efficient light rare earths (according to customer requirements) Protection class IP67 Operating temperature -30 degrees to 70 degrees, wind power ≥150Km / h Lighting time of 4 to 14 hours (can be adjusted as needed) Pole height 4 meters to 12 meters (according to customer requirements production) work to guarantee continuous rainy days 5-7 rainy days (regional / seasonal variations are different) (according to customer requirements) solar panels, using a conversion rate of single / polycrystalline silicon structure material, hoop used is a steel and aluminum construction material, steel poles are systemic, galvanized surface spray, controllers, light control + control, anti-short protection of intelligent controllers, batteries, water maintenance-free gel batteries. Chengde solar lights package that we used is carton packaging, interior containing foam, so that lights in the transport process is not easy to produce wear and deformation due to compression, full auto transport, faster and more convenient. Chengde use of solar street lighting is widely used in urban and rural roads, highways, water conservancy dikes, bridges, islands, parks, scenic areas, industrial areas, city squares, residential areas and other places. Chengde solar street lighting service we produce all products are strictly enforced in accordance with standard materials testing, strict production process control, finished product shipment inspection to ensure that customers spend with the products, the company built a set of comprehensive pre-sale service system, all for the benefit of customers, peace of mind for our customers. We are committed to using the products if there is a problem, the city, we will rush day troubleshooting, if it is in the field, we will arrive in two days, to help customers solve the problem.
