How to reasonably solve this problem brings a challenge to everyone. Some may increase power generation by designing larger solar panels, but this result will inevitably increase the system cost even more. Is there a way to increase power generation without increasing system cost?
MPPT controller is undoubtedly a good choice. The so-called MPPT (Maximum Power Point Tracking) is the maximum power point tracking.
The maximum power point tracking controller is a device designed in the controller that can perform intelligent calculation and implement tracking at any time to realize real-time monitoring of the power generation voltage of the solar panel, and track the highest voltage and current value (VI). electrical energy, allowing the system to charge the battery with the highest efficiency.

In the off-grid photovoltaic system, the solar charge and discharge controller used to protect the battery from overcharging and overdischarging and prolong the battery life is indispensable. After years of development, the technology of Pulse Width Modulation (PWM) type charge controller has become very mature. However, we found that in practical cases, the power generation of photovoltaic power plants after operation is often lower than the design value at the beginning of construction, which not only causes waste of the system, but also brings a lot of inconvenience to the application.
