What does MPPT stand for in the context of PV systems?

In the context of photovoltaic (PV) systems, MPPT stands for Maximum Power Point Tracking. This technology is used in solar inverters to optimize the energy output from solar panels. Solar panels have a specific point at which they produce maximum power, known as the maximum power point (MPP).

MPPT algorithms adjust the load on the solar panels to ensure they operate at this point despite changes in conditions such as temperature, sunlight intensity, and shading. By continuously monitoring the output of the solar panels, the MPPT system can change the electrical operating point to capture the maximum possible power, thereby improving the efficiency of the entire solar power system.

Understanding this concept is fundamental for anyone working with PV systems, as it directly impacts the amount of energy harvested and the overall performance of solar installations.
