What is MPPT and why is it important in PV array design?

MPPT stands for Maximum Power Point Tracking, a control technique used in PV systems to maximize power output by constantly adjusting the operating voltage. Solar panels don’t deliver their best power at a single fixed voltage because their current–voltage curve shifts with irradiance and temperature. The point where the product of voltage and current (the power) is highest—the maximum power point—moves as conditions change. MPPT uses a DC–DC converter and a control algorithm to keep the panels operating as close as possible to that moving point, so the load seen by the panels is continuously tuned to harvest the most energy. As sunlight varies or the panels heat up or cool down, MPPT adapts, improving the overall energy yield of the array. The other terms don’t describe this dynamic optimization process.
