Solar Panel Maximum Power Transfer Increases from 63.6% to 90% by using twoSinewave Inverters with 90o phase shift

[摘要] This letter shows that the theoretical efficiency at which the solar panel operates at the Maximum Power Transfer Point is only 63.6% with a single pure sine wave inverter (PWM based) and the efficiency can be increased to 90% by using two sine wave inverters with 90 degree phase shift. A 3 phase inverter can further increase the efficiency to 95.54%.
