With the increasing scarcity of traditional energy sources, the application of solar energy will become more widespread, especially in the solar street light system, which has developed into an industry in just a few years.
1. Currently, one of the most significant constraints on the application of solar power generation is price. Taking a dual-path solar street light system as an example, assuming the downstream area receives 4.5 hours of effective sunlight per day, discharges for 7 hours per night, and a 20% reserve for the solar panels, the solar panels alone would require approximately 160W, costing 4800 yuan. Adding the cost of a 180AH battery pack, also around 1800 yuan, the high initial investment cost of the entire streetlight is a major bottleneck in the solar street light system application.
2. When using the street lighting system as a whole, the battery life should also be considered. Regular batteries typically lose some of their charge after six months; some even drop to around 50%. However, they come with a warranty of three to five years. This will inevitably have an impact on nighttime lighting during prolonged periods of cloudy or rainy weather. Therefore, choosing a high-quality battery is critical.
3. The selection of the controller is often overlooked by contractors. Controller quality varies greatly; even a 12V/10A controller has different market prices. Although it is the smallest value component in the entire street lighting system, it is a very important element. Damage to the controller has a direct impact on the lifespan of the solar panels and the overall cost of purchasing the system. As a result, the following safety measures are essential: First, choose a controller with low power consumption. Because the controller runs continuously, it should consume less than 1 milliampere. Pick a controller that regulates power. Power-regulating controllers find extensive application. When there is little pedestrian traffic at night, they can automatically turn off one or two lighting circuits and control the power of LVD lights. Along with these energy-saving features, be mindful of the controller’s battery and component protection features. The battery’s lifespan can be increased and protection provided by a good controller. To avoid the battery being overdischarged, try to set the controller’s undervoltage protection value as low as possible.
4. Preventing theft is essential for places that are remote from cities. Ineffective theft prevention during construction is a common mistake made by contractors, which results in solar panel theft, disrupts regular lighting, and causes needless property damage. Batteries are currently the most frequently stolen item in engineering cases. Battery burying is a good anti-theft measure, and welding the battery box on the light pole is the best way to reinforce it.
5. Waterproofing the controller. Controllers are not affected by water intrusion and are typically located in the battery box or lamp cover. Rainwater, however, could get into the controller terminals through the connecting wires and cause short circuits in practical engineering situations. As a result, the external connections should also be “U” shaped, and the internal connecting wires should be bent into a “U” shape and secured during construction. By doing this, short circuits are prevented and rainwater is kept out of the controller. It is also possible to apply waterproof adhesive to the interfaces between the internal and external wires.
6. Many real-world solar street light applications are unable to provide adequate lighting, particularly on overcast or rainy days. Aside from poor-quality components, another major reason is the sole focus on reducing component costs rather than designing and configuring to meet requirements. On cloudy or rainy days, solar street light systems fail to illuminate due to poor quality solar panels and batteries.
