This ensures the maximum power is pulled from the solar cell or module. Factors Affecting Maximum Power Point. The MPP on a solar cell''s I-V curve changes with factors like sunlight, cell heat, and the load. A shift in the sun''s power moves the MPP up or down the curve. Rising cell temperatures lower the MPP by decreasing the open-circuit
