What does the brightness of a solar light depend on?

It's a cascading problem. The brightness of the solar lamp directly depends on the actual lighting power set by the controller, and the actual lighting power depends on the system configuration size. Therefore, from the source, the brightness of the solar lamp depends on the system configuration.

The solar light is the actual power given by the controller, and the actual power plus the full power working time is the power consumption of the solar lamp on the day. Assuming a certain working time, the greater the power, the greater the power consumption. The greater the power consumption, the greater the amount of charging required and the storage capacity of the battery, so the larger the configuration of the solar lamp needs to be, that is, the larger the solar panels and batteries need to be.

Another big determinant is the system voltage. Now commonly used low-voltage systems, the maximum actual power is only 20-30W. Need more power, higher brightness need to do 12V or 24V system. The maximum power of the 12V system is 60W, and a few controllers can reach 80W. The maximum power of the 24V system is generally 120W, and a few controllers can reach 160W.

Another factor is the overall lighting effect. The same actual power, the higher the light efficiency of the lamp, the greater the brightness, which is why we strongly recommend good lamps. Good lamps are not much expensive, but the effect can be increased a lot, the so-called spend little money to do big things.
