Peru has a large territorial span, with a large number of municipal projects distributed in the Andean plateau region. The air in high-altitude areas is thin, and the ultraviolet intensity is much higher than that in plains. The sunshine duration is sufficient and the radiation value is high, making it a unique application environment for solar lighting. However, it also poses a strict test for lighting products. Many high-altitude towns are far away from the main power grid, and the cost of laying electricity across mountains is extremely high. Excavation and wiring are difficult, and the construction period is long.

LEADRAY Street Lamp Factory has created a dedicated solar street lamp solution for the Peruvian plateau municipal project, which is adapted to the strong ultraviolet environment of the plateau and equipped with an intelligent dimming system. It takes into account the lighting standards, project budget, and long-term durability of municipal roads, providing stable and reliable off grid lighting options for local municipal units and EPC contractors.

The lamp body shell is made of die cast aluminum alloy, combined with high weather resistance and UV resistant fluorocarbon spray coating, which is not easy to fade, powder, or peel after long-term exposure to high altitude sun; The sealing strip is made of UV resistant silicone rubber to prevent aging, cracking, and water ingress.

The photovoltaic panel is made of high-grade UV resistant backsheet and high transparency tempered glass, with a surface anti fouling coating to resist strong UV continuous erosion and maintain stable power generation efficiency; The battery is made of high-temperature resistant and long-life lithium iron phosphate, which is suitable for the huge temperature difference in high altitude and can slow down capacity degradation.

The intelligent dimming control system is the core of this solution. Built in MPPT photovoltaic controller, accurately collects changes in high-altitude lighting, automatically identifies dusk and early morning; Support custom dimming strategies for multiple time periods, with the ability to set multiple modes including full power, half power, and low power. Engineers can write the program in advance based on the sunshine data of the project location, maximizing the use of abundant sunshine on the plateau, extending the battery life on rainy days, and reducing battery cycling losses.
IP66 protection level, it can resist the sudden rainstorm and sand dust on the plateau, prevent moisture from entering the interior of the lamp body, and cope with the changeable weather in mountainous areas.

Many high-altitude municipal roads are built along the mountains, with many bends and steep slopes. Pedestrians, motorcycles, and small trucks mix in, and strict requirements are placed on the uniformity of road illumination and anti glare ability. Poor lighting can easily lead to traffic accidents. The power grid coverage in high-altitude areas is scattered, with unstable voltage and frequent power outages, making it difficult for traditional city circuit lights to operate stably.
In addition, the operation and maintenance conditions of high-altitude projects are limited, and many points are located in remote mountainous areas with inconvenient transportation. The maintenance and replacement of lighting fixtures are time-consuming and labor-intensive. If the endurance of the lighting fixtures is insufficient and they are turned off directly on consecutive cloudy days, it will bring huge pressure to municipal management. Old solar street lights that rely solely on fixed power for lighting either have insufficient brightness or consume batteries too quickly, resulting in reduced battery life.

Intelligent dimming is a must-have for high-altitude projects: matching local sunlight patterns, dynamically adjusting power, maximizing the use of abundant high-altitude light energy, while protecting batteries and extending the service life of the entire lighting system. It is also an increasingly high-frequency technical requirement in Peru's municipal bidding.

LEADRAY street lamp factory supports customized color temperature, dimming logic, remote monitoring module, and municipal project logo. Solar street lights do not require excavation of long-distance cable trenches and can be installed by erecting poles, greatly reducing construction difficulty, shortening construction period, and reducing earthwork in rugged mountain roads and complex geological plateau areas.

After the project is implemented, there will be almost zero electricity bills, which is in line with Peru's policy direction of promoting renewable energy, rural and high-altitude municipal energy-saving transformation. We can also provide matching UV resistant lamp posts and grounding accessories of the same standard, packaged and delivered as a whole to simplify the procurement process for engineering companies.
