1.  1. What Is An MPPT Charge Controller?

   MPPT stands for maximum power point tracking. The MPPT charge controller uses maximum power point tracking technology to ensure that the loads receive maximum current to be used (by quickly charging the battery). Maximum power point could be understood as an ideal voltage at which the maximum power is delivered to the loads, with minimum losses.

   
   

2. 2. The difference between monocrystalline and polycrystalline solar panels

   The panel cells' crystal purity is the primary distinction between the two kinds of solar panels. While polycrystalline solar panels use solar cells built from many silicon pieces fused together, monocrystalline solar panels use solar cells made from a single silicon crystal. Generally, the efficiency of monocrystalline solar panels is higher than that of polycrystalline solar panels (about 20% higher), and the size of monocrystalline solar panels of the same specification is smaller than that of polycrystalline solar panels. But monocrystalline solar panels are also relatively more expensive. However, in the case of weak light, the efficiency of polycrystalline solar panels is higher than that of monocrystalline solar panels.

   
   

3. 3. Why are my LED solar lights not working?

   Because solar lights rely on sunshine for their power, they will not function if they do not receive the required amount of sunlight. As a result, ensure that your solar light is installed or positioned in an area where it will receive sufficient sunshine to charge its battery and function effectively.
