In outdoor road lighting, the energy consumption of electric streetlights has sharply increased with the continuous improvement of urban road networks. Solar streetlights are a genuinely green and energy-saving product; their principle is to use the photovoltaic effect to convert light energy into electrical energy stored in batteries through solar panels. At night, the batteries power the light sources without the need for electricity costs. In the future, solar streetlights have a great potential for application. However, there may be instances where the brightness of solar streetlights is not as high as that of electric streetlights. What could be the reason for this? Next, we will introduce this issue.
Reasons why the brightness of solar streetlights is not as high as that of electric streetlights:
1. Solar streetlights do not operate at full power
As the configuration of solar streetlights is higher, their price also increases. If they operated at full power, the cost would be excessive, exceeding many contractors’ budgets. Therefore, currently, solar streetlights in the market operate by reducing the light source power through solar controllers.
2. Low configuration of solar streetlights
Solar streetlights of the same height generally use a light source power less than that of electric streetlights, and the height of solar streetlights typically should not exceed 10 meters. Electric streetlights are usually around 9 to 12 meters tall, thus leading to an obvious perception that solar streetlights have lower brightness than electric streetlights.
3. Poor quality of solar streetlights
The booming market for solar streetlights has led to the entry of many small, workshop-style manufacturers. Lacking in competitive advantage, these manufacturers often resort to cutting corners to reduce costs and increase profit. For instance, subpar materials may be used in the chips and housings of streetlight heads, as well as in the quality of lithium battery cells and solar panel silicon. This naturally results in subpar work efficiency and brightness of solar streetlights.
The above points explain why the brightness of solar streetlights may not match that of electric streetlights. Solar streetlights are energy-saving, environmentally friendly, green, and easy to install. We should not avoid using them just because their brightness is lower than that of electric streetlights. If sourced from a reputable solar streetlight manufacturer, the lighting effect of solar streetlights can also be quite satisfactory.
