Be cautious when purchasing solar LED street lamps to avoid pitfalls. Solar Light Factory Tianxiang has some tips to share.
1. Request a test report and verify the specifications.
2. Prioritize branded components and check the warranty period.
3. Consider both configuration and after-sales service, rather than simply price, to ensure the product is suitable for your specific use case.
Two Typical Traps
1. False Labeling
False labeling refers to the dishonest practice of reducing product specifications while falsely labeling them according to the agreed-upon specifications, thereby profiting from the resulting price difference. This is a typical trap in the solar LED street lamp market.
Falsely labeling components with false specifications is typically difficult for customers to identify on-site, such as solar panels and batteries. The actual parameters of these components require instrument testing. Many customers have experienced this: The prices they receive for the same specifications can vary widely from vendor to vendor. Generally speaking, raw material costs for the same product are similar. Even if there are some price differences, labor costs, or process variations between regions, a 0.5% price difference is normal. However, if the price is significantly lower than the market price, you’re likely receiving a product with reduced specifications and falsely labeled components. For example, if you request a 100W solar panel, the merchant may quote an 80W price, effectively giving you a 70W power rating. This allows them to profit from the 10W difference. Batteries, with their higher unit price and higher returns on false labeling, are particularly vulnerable to false labeling.
Some customers may also purchase a 6-meter, 30W solar LED street lamp, only to find that the output is completely different. The merchant claims it’s a 30W light, and even counts the number of LEDs, but you don’t know the actual power output. You’ll only notice that the 30W light isn’t working as well as others, and the operating hours and number of rainy days vary.
Even LED lights are being falsely labeled by many dishonest merchants, who pass off low-rated LEDs as high-power. This false power rating leaves customers with only the number of LEDs, but not the rated power of each.
2. Misleading Concepts
The most typical example of misleading concepts is batteries. When purchasing a battery, the ultimate goal is to determine the amount of energy it can store, measured in watt-hours (WH). This means how many hours (H) the battery can discharge when a lamp with a certain power (W) is used. However, customers often focus on the battery’s ampere-hour (Ah). Even dishonest sellers mislead customers into focusing solely on the ampere-hour (Ah) value, ignoring the battery’s voltage. Let’s first consider the following equations.
Power (W) = Voltage (V) * Current (A)
Substituting this into the amount of energy (WH), we obtain:
Energy (WH) = Voltage (V) * Current (A) * Time (H)
So, Energy (WH) = Voltage (V) * Capacity (AH)
When using Gel batteries, this wasn’t a problem, as they all had a rated voltage of 12V, so the only concern was capacity. However, with the advent of lithium batteries, battery voltage became more complex. Batteries suitable for 12V systems include 11.1V ternary lithium batteries and 12.8V lithium iron phosphate batteries. Low-voltage systems also include 3.2V lithium iron phosphate batteries and 3.7V ternary lithium batteries. Some manufacturers even offer 9.6V systems. Changing voltages also changes capacity. Focusing solely on the amperage (AH) will put you at a disadvantage.
