In rural areas, the construction of basic lighting facilities is increasingly using solar street lights to replace traditional grid-powered street lights. However, during the actual installation process, many customers still follow the traditional placement methods used for grid-powered street lights. This has resulted in problems such as solar street lights not lighting up after a few days post-installation or only illuminating for a short period at night. Today, I will summarize five common installation mistakes that can lead to failure in the normal operation of solar street lights.
Error 1: Too many obstructions at the installation site
The principle of solar street lights involves solar photovoltaic panels at the top receiving sunlight, converting it into electrical energy stored in batteries, and supplying power to LED lights at night. If the installation site has too many obstructions, like tree leaves or buildings, it will block sunlight, affecting the photovoltaic panel’s ability to absorb and utilize solar energy, leading to decreased charging efficiency.
Solution:
When selecting a site for solar street lights, ensure it is as far away from obstructions as possible. If obstructions cannot be avoided, ensure that the solar photovoltaic panels face south without any blockage, or at least receive sunlight for no less than 6 hours.
Error 2: Nearby light sources
The solar street light control switch operates mainly on light sensitivity, allowing automatic adjustments for lighting duration based on varying daylight hours throughout the seasons. The main control component is on the photovoltaic panel, so if there are nearby light sources, it can mislead the sensors, resulting in the lights not turning on.
Solution:
Ensure there are no other light sources near the solar photovoltaic panel. If other light sources cannot be removed, inform us in advance, and we will adjust the controller to time-based control.
Error 3: Charging the solar panel indoors
Some customers, in need of lighting, install solar lights indoors, such as in garages or hallways. Although these areas receive some light during the day, it does not provide sufficient charging efficiency compared to outdoor sunlight, which can lead to battery depletion and eventual damage over time.
Solution:
Where possible, install solar lights outdoors. If indoor installation is necessary, implement outdoor charging while using indoor lights; this means separating the solar photovoltaic panel from the light fixture.
Error 4: Extending the solar charging wires arbitrarily
In some cases, due to disturbances at the installation site, customers may place the solar panel and the light fixture at a long distance apart, sometimes over ten meters. They often connect them using standard market-grade two-core wires without consideration. Since common wire quality is generally poor and longer wire lengths suffer from high current losses, the charging efficiency decreases significantly, affecting the illumination duration.
Solution:
If needing to extend the installation distance, please inform us in advance. We will assess the situation and increase the power of the photovoltaic panels accordingly to ensure the solar energy can charge properly.
Error 5: Incorrect orientation of the photovoltaic panel
This mistake often occurs with pole-mounted solar street lights, where the photovoltaic panels need to be secured before installing the pole. Many times, the panels are not oriented correctly, leading to inadequate sunlight exposure and no charging.
Solution:
Ensure the photovoltaic panels are primarily directed southward during installation. First, determine the LED’s light projection direction, and then set the orientation of the photovoltaic panel.
