System Design Solution Based on Heterojunction Solar Cell

Abstract

Based on the development status of PV modules, this paper analyzes the differences of various mainstream technology route modules in the market.In combination with the irradiation conditions of the project site, the system design scheme using heterojunction components is emphasized, and the correct selection of photovoltaic inverter and capacitance ratio is also described.The system cost and kilowatt-hour cost of initial input of heterojunction module and conventional high-efficiency single crystal module are compared, and the system using heterojunction module has advantages.
