Solar powered street lamps are commonly used lighting projects in outdoor lighting. In recent years, more and more people choose solar powered street lamp instead of traditional street lamp. Price is one of the reasons that people choose the solar street lamp. What factors will affect the solar powered street lamp price? The climate conditions and the demand for illumination differ as well as the innovation and design. Great innovation will always reduce the cost of the products. The solar powered street lamp is composed of solar panel, light pole, controller and rechargeable battery, lighting fixture. To help users choose high performance street lamp, we will introduce factors affecting the solar powered street lamp in details.

1. Solar panels and rechargeable battery

Solar panels and battery are two central parts of the lamp. Solar panel battery components include monocrystalline silicon, polycrystalline silicon, amorphous silicon, and thin-film batteries. Different materials have different photoelectric conversion efficiency. Under the same conditions, the efficiency of monocrystalline silicon is better and the price is higher. The area of solar panels also affects the price. In order to achieve the necessary photoelectric conversion efficiency, in addition to the selection of materials, the area of solar panels is also very important. The same material, the larger the area, the higher the efficiency as well as the price. Battery includes lead-acid battery, ternary lithium battery, lithium iron phosphate battery. Lithium phosphate battery is the most cost-effective battery but the price is the highest.

2. Light pole

Height of the light pole decide the illumination range. The price of a light pole is mainly affected by its shape, wall thickness, upper and lower caliber size, flange size and thickness of the base plate. The life span of light poles using integral hot-dip galvanizing can reach 20-25 years, which is the first choice of customers. If the price of law material increases such as the hot-dip galvanizing, the price of the solar powered street lamp will increase, too.

3. Controller and LED lighting fixture

Controller and LED lighting fixture play significant roles in choosing solar powered street lamp. When the solar street lamp is sunny, the solar panel generates electricity through the controller during the day and stores it to the battery. It controls the charge of the battery to prevent overcharge and discharge. Choose the appropriate controller according to the type of lamp: step-up cross-current controller, step-down cross-current controller, constant voltage controller, etc. Then select the controller (output voltage range, output power range, load current setting range) that meets the requirements of the output electrical parameters according to the LED lamp power, working voltage, and current. LED lighting fixture is the most cost-effective light source for solar powered street lamp according to many factors.

4. Lighting hours and the number of consecutive rainy days

The lighting hours is related to the solar panels and the battery. Normal solar powered street lamp can support lighting for 6-12 hours. If longer lighting time is needed, higher configuration of the solar panel and battery is also needed. The number of consecutive rainy days is also an important factor that affect the price of solar powered street lamp. The battery will store the energy in the sunny day and use the stored electricity to provide lighting in rainy days. The climate condition differs in different countries, so the number of consecutive rainy days needs to be confirmed. Battery of larger capacity is needed.

In conclusion, the price of solar powered street lamps is affected by various factors including the raw material, the parts as well as the climate conditions. Users should make an appropriate choice based on these factors.
