Solar Street Lights
Although applicable nationwide, their effectiveness can vary greatly. Why does this happen? Let’s explore the topic of street lights together!
The actual effective sunlight hours and light intensity differ across regions, so manufacturers of solar street lights will customize and produce lights according to the specific conditions in different areas. Therefore, when installing or upgrading solar street lights, it is important to choose suitable lights based on the local situation to avoid wasting resources while still meeting daily use needs.
First, we need to understand the working principle of solar street lights. They utilize the photovoltaic effect of solar cells, where sunlight is absorbed during the day to generate electrical energy. This energy is stored in batteries via a controller. When night falls or when the ambient light level drops below a certain threshold, the controller automatically discharges the battery to turn on the street lights.
The data required for designing solar street lights is obtained by looking up the latitude and longitude of the installation site. The tilt angle and azimuth of the solar panel are determined using solar radiation databases, allowing for calculations of the standard peak sunlight hours in that region. The power of the light source directly affects the stability of the entire system’s parameters. The duration of nightly operation determines the size of the components in the solar street light system. This operating time allows for the initial calculation of daily power consumption and the corresponding charging current for the solar panels.
The number of continuous overcast days that the solar street light needs to operate reliably determines the battery capacity and the power required from the solar panels to recharge the batteries after cloudy days. The interval between two consecutive overcast days is also a crucial parameter for determining the power needed from solar panels to charge the batteries adequately.
Therefore, when purchasing solar street lights, it is essential to pay special attention to whether the system’s design concepts and key points align with the local actual conditions. One should not solely pursue low prices to save investment nor excessively seek high performance, leading to resource wastage.
