Solar street lamps are lighting fixtures powered by solar energy, which help save electricity. When selecting solar street lamps, we will compare solar street lamps’ buck and boost controllers, explaining them from the aspects of light source and current.
1. Current.
The current mentioned here refers to the charging current. The charging speed of solar panels varies with light conditions; the more abundant the sunlight, the greater the charging current. Current is generally represented in units of A. Different controller manufacturers set different currents. For instance, when considering 5A and 10A controllers, if the solar panel’s power reaches over 100W, the output current is about 5.8A. Using a 5A controller would lead to a risk of damage to the controller.
2. Light Source.
Different controllers use different light sources. Buck constant current integrated controllers generally use three parallel arrangements, based on the single chip voltage of the LED beads being 3.3V. The voltage for the three chips in series is 9.9V (based on basic physics knowledge; series raises voltage, while parallel increases current). Boost constant current integrated controllers usually use around 10 series connections, with an output voltage of 33V. We classify the solar street lamp system voltage as 12V/24V. When considering cost issues, if the battery capacity is below 100Ah, we typically use a single 12V system. The buck output power is 30W, while the boost output power is 60W (heat dissipation affects output power).
The above information outlines the differences between buck and boost controllers for solar street lamps, hoping it helps everyone in selecting solar street lamps.
