How to choose a cost-effective solar street light

Detailed configuration

Lamp power: It is crucial to choose the lamp power accurately according to the actual lighting demand. If the power is too large, it will cause energy waste and increase costs; if the power is too small, it will not meet the lighting requirements. Generally speaking, due to the relatively small amount of people and traffic in the countryside, 10 - 30 watts of lamp power can meet the basic lighting requirements; while the city's main roads are frequently traveled by people and vehicles, 50 - 100 watts of lamp power is needed to ensure adequate lighting.

Battery capacity: To ensure that the battery capacity to meet the night lighting hours and continuous rainy weather power needs. At the same time, be wary of products on the market that falsely label capacity. Can be based on the local sunshine hours, lamps and lanterns power and desired lighting hours, through the professional formula to calculate the required battery capacity. For example, the average daily sunshine hours in a certain area is 6 hours, the power of the lamps is 30 watts, and it is expected that the street lamps can work normally in 3 consecutive cloudy and rainy days and illuminate for 8 hours a day, and the required battery capacity is calculated to be about 120 ampere hours.

Solar panel size: the size of the solar panel is directly related to the power generation capacity, need to be combined with the local light conditions and the lamps and lanterns power demand reasonable choice. In areas with sufficient light, a smaller size of high-efficiency solar panels can be used; in areas with general light conditions, a larger size of panels is needed to ensure sufficient power generation.

Light pole material: common pole materials are steel, aluminum alloy and stainless steel. Steel light pole cost is relatively low, but in the outdoor environment is prone to rust, need regular maintenance; aluminum alloy light pole has the advantages of light weight, corrosion resistance, moderate price; stainless steel light pole is the most durable, corrosion-resistant performance is strong, but also the highest cost. In the choice, to consider the use of the environment and budget, such as the seaside and other corrosive environment, give priority to aluminum alloy or stainless steel poles; ordinary areas, if the budget is limited, you can choose the anticorrosion treatment of steel poles.

Road requirements

Road width and luminaire type: The width of the road is a key factor in deciding whether to choose single-arm or double-arm solar street lights. Usually, the width of the road is less than 6 meters, single-arm solar street light can meet the lighting needs of a single side, installation and cost is relatively low; road width is greater than 6 meters, in order to ensure that both sides of the road have a good lighting effect, you can consider the double-armed solar street light, but its cost will increase.

Light spacing and brightness: Determine the appropriate light spacing and brightness according to the function of the road. As a major traffic artery in the city, the brightness requirements are higher, the light spacing can be set to 25 - 35 meters to ensure the safe passage of vehicles and pedestrians; community roads mainly serve the residents in their daily travel, the brightness can be moderate, the light spacing can be appropriately increased to 30 - 40 meters, which can meet the lighting needs, but also reduce the cost.

Pole height and power/brightness: The height of the pole is closely related to the power and brightness of the required lamps. Generally speaking, the higher the pole, the wider the light coverage, but at the same time, a higher power luminaire is needed to ensure the brightness of the ground. For example, a 6 meter high pole with 30 - 50 watt lamps is suitable; an 8 meter high pole needs 50 - 80 watt lamps to achieve good lighting effect.

Warranty time

Generally speaking, the warranty time of solar street light ranges from 1 - 5 years. Longer warranty time usually means that the quality of the street light is more guaranteed and the manufacturer has more confidence in the product. Because during the warranty period, if the product has quality problems, the manufacturer is responsible for repair or replacement. However, the price of products with a long warranty is often relatively high. Consumers in the choice, to consider the price of the product, quality and their own expectations of the product life, weigh the length of the warranty and price, choose cost-effective products.

Brand

Check the brand's official website, industry forums, e-commerce platform evaluations and other channels through the Internet to gain an in-depth understanding of the brand's R&D capabilities, production scale, product quality certification and other aspects of strength. Check whether the brand has a professional R&D team, whether it has large-scale production capacity to ensure the supply of products, and whether it has obtained relevant international and domestic quality certificates, such as ISO quality management system certification, CE certification and so on.
