What Are The Determinants For Solar Street Lights Price?

A source of renewable energy is solar street lighting. The longer time passes, the more well-known they become. The technology behind solar street lighting is also always evolving. PBOX is an example of a producer who makes use of cutting-edge technologies. Also, prices change along with technological advancements. Several reasons are given for the varying cost. The purpose of this essay is to educate you of the numerous elements that affect the cost of solar street lighting.

Price determinants for solar street lighting
1. A solar panel

There are two primary types of solar panels. These include silicon that is monocrystalline and silicon that is polycrystalline. The efficiency of photoelectric conversion is what distinguishes the two kinds of solar panels. The monocrystalline solar panel has the best conversion rate of the two, ranging from 17% to 22%. Comparatively, the conversion rate of polycrystalline silicon ranges from 14% to 17%. Polycrystalline solar panels don't have as high of a manufacturing cost as monocrystalline ones. As a result, monocrystalline silicon solar panels will cost more than polycrystalline silicon solar panels. The solar panel will have a greater conversion efficiency while being more expensive.

2. A street lamp post
There are several types of street light poles. The wall thickness, material, number of arms (whether double or single), and design of the pole are the factors that make each street light unique. Also, there are many techniques for galvanizing the street light. Cold galvanizing and hot galvanizing are two of the several techniques. In comparison to hot galvanizing, cold galvanizing is less expensive. This is so that hot galvanizing, as opposed to cold galvanizing, has a higher anti-corrosion effect. Hence, the price of solar street lights is influenced by the various sizes of the materials used, the process of galvanizing, and the thickness of the walls.

3. Battery for solar street lights
Ternary Lithium batteries, LifePO4 lithium-ion batteries, and lead-acid lithium batteries are among the several batteries that are often found in solar street lighting. Moreover, the batteries often have a voltage of 24V or 12V. Since they provide the highest level of environmental protection and need no maintenance, Ternary Lithium batteries and LifePO4 lithium-ion batteries are often employed. Ternary Lithium batteries are often used in low-end solar street lighting due to their very low price. LifePO4 lithium-ion batteries have a premium price because to their rapid charge-discharge rate, but over time, they need no maintenance, making them an excellent investment.

4. A clever controller
Maximum Power Point Tracking (MPPT) and Pulse-Width Modulation are the two kinds of controllers (PWM). The two controllers charge batteries quite well. Moreover, the solar off-grid industry often employs the two controller technologies. PWM is less expensive than MPPT. Little solar off-grid systems are better served by PMW, but big solar off-grid systems are better served by MPPT. The MPPT will be less effective if utilized in a small off-grid installation. Hence, the cost of the solar panel street light will vary depending on the intelligent controller employed.

Conclusion
The many components that make up solar street lighting result in a range of costs. As you can see from the image above, the price of the solar street lighting depends on the varied grade of the materials. Moreover, solar street lights cost more to produce than conventional street lights, but over time, they are less expensive because of their low maintenance requirements.
