How to effectively reduce the cost of photovoltaic systems has become a new research topic in the photovoltaic industry. At present, the frames of photovoltaic industry modules are mainly made of aluminum alloy profiles. Aluminum profiles are expensive and come in many types and specifications. The photovoltaic industry is gradually entering a subsidy-free era. How to effectively reduce system costs and achieve grid parity has become a new topic in the photovoltaic industry. Considering the cost of photovoltaic module packaging materials, traditional aluminum alloy frames are subject to raw material cost factors, and there is little room for frame cost reduction.
