Nowadays, consumers are particularly concerned about two aspects when purchasing
rural solar street lamp products
. One is quality, and the other is price. Speaking of price, some people may not know what factors contribute to it. Below, we will discuss the components that make up
the price of solar street lamps
.
1.
Solar Panels for Rural Solar Street Lamps
Currently, the common solar panels in the market are monocrystalline and polycrystalline. Monocrystalline solar panels have stable performance parameters, making them suitable for use in southern regions with more rainy days and less sunny weather. Polycrystalline solar panels are produced using a relatively simpler process and are cheaper than monocrystalline panels, making them ideal for areas in the east and west with abundant sunlight. We recommend using monocrystalline panels due to their higher conversion efficiency.
2.
Batteries for Rural Solar Street Lamps
There is a wide variety of batteries available in the current market. The most commonly used are lead-acid batteries and lithium batteries. Lead-acid batteries are suitable for low-temperature, high-rate discharge and have lower energy density, making them the choice for most solar street lamps. They are sealed and maintenance-free with a lower price. However, care must be taken to prevent lead pollution, and they should be gradually phased out. Lithium batteries use lithium metal or lithium alloy as the negative electrode material and utilize a non-aqueous electrolyte solution. The reactivity of lithium metal demands high environmental standards during processing, storage, and use. With advancements in technology, lithium batteries have become mainstream.
3.
Controllers for Rural Solar Street Lamps
The solar street lamps we utilize generally apply 12V, 24V 10A, and 20A controllers, which have overcharge and over-discharge protection functions. These devices can automatically prevent battery packs from overcharging and over-discharging. The charging and discharging controllers should also include short-circuit protection, disconnection protection, reverse connection protection for solar panels, and night discharge prevention. Additionally, they have light control and time control features, allowing automatic illumination or extinguishing based on the brightness of the sky and setting of working hours for each night.
4.
Light Sources for Rural Solar Street Lamps
Currently, we use imported American chips for our light sources. High-quality light sources have better light efficiency, lower light decay, and a lifespan of up to 50,000 hours.
5.
Lamp Poles for Rural Solar Street Lamps
The height of the lamp post can be adjusted according to road requirements, but it is essential to ensure the lamp post’s wind resistance. The lamp poles are made from high-quality Q235 steel and are formed in one go using a large bending machine. They undergo hot galvanization and electrostatic spraying to ensure excellent corrosion and rust resistance.
