For customers, there may be a question, which kind of street lamp is more cost-effective, we all want to buy things at a good price, so the purchase of solar street lamp is no exception. But people generally know little about the solar street lamp, and they don't know how to judge the price and quality of the solar street lamp.
The price components of solar street lamps are closely related to their own configuration. Specific to each component, and its performance, quality has a direct relationship. For example, the composition of solar street lamp is generally LED light source, solar panel is also called solar cell module, solar battery is also called lead-acid maintenance-free battery (colloid maintenance-free battery), street lamp pole, light control + time control controller, etc. Each of these components will have a significant impact on the whole system.
Generally, if the price of solar street lamp is low, the quality of at least one or two parts in the whole system can not meet the requirements, which will not be found in the short term in electronic products, but long-term use will lead to instability of the whole system, equipment failure or equipment damage.
There is also a guarantee of 3 years and 5 years promised by individual manufacturers, which is not scary if there is a guarantee. The guarantee cost of an enterprise is bound to be included in the unit price of sales. If the warranty lasts for five years, the guarantee cost will be quite high. If the unit price is much lower than the market price, it can only show that the quality of the product is much lower than the market price. Otherwise, where will the profit come from? For example, let's buy a laptop computer and guarantee it for two years for 4,000 yuan. But if we extend the warranty for one year, we need to pay 500 yuan for it. Isn't that the so-called benefit of long quality assurance?
What we want is not the quality assurance, but the real product. After all, we don't expect the product to be repaired after the sale because it's bad. That's not good for everyone. So the purchase of products must depend on the quality.
