Title:
METHOD FOR INSTALLING MAXIMUM POWER POINT TRACKING (MPPT) CONTROLLER, AND PHOTOVOLTAIC SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/077825
Kind Code:
A1
Abstract:
A method for installing a maximum power point tracking (MPPT) controller, and a photovoltaic system. The installment method comprises: acquiring a shielding area ratio of a photovoltaic string in the photovoltaic system (101); optimizing the shielding area ratio to generate a target shielding area ratio (102); determining a target position from the photovoltaic string according to the target shielding area ratio (103); and installing an MPPT controller at the target position (104). Therefore, the overall power generation efficiency of the photovoltaic system can be improved, the cost of the photovoltaic system is saved, and the earning yield is increased.
