PV module internal protection circuit structure with single power generation unit

Abstract

The present invention discloses a PV module internal protection circuit structure with a single power generation unit, comprising a plurality of solar cells, a plurality of solar cells combined to form a power generation unit A and a power generation unit B; The positive polarity, the negative polarity, the positive polarity, the negative polarity, the positive polarity and the negative polarity;the polarity of the battery strings in columns B to B is negative, negative, positive, negative, positive and negative in sequence, and the bus bar has three split wires box. The invention can effectively improve the output power and the power generation efficiency of the half-chip component and reduce the procurement cost of the component packaging material, so as to greatly enhance the actual power generation of the component system end and effectively reduce the electricity cost. In addition, because the number of the divided power generation cells increases, The probability of failure willbe greatly reduced during the test, especially the temperature-related testing is less likely to fail than the conventional half-chip design and is worth promoting.

Description

Technical field [0001] The invention relates to the technical field of solar crystalline silicon sliced ​​battery module packaging application technology, in particular to a photovoltaic module internal protection circuit structure with a separate power generation unit. Background technique [0002] As the global consumption of conventional fossil energy such as coal, oil, and natural gas accelerates, the ecological environment continues to deteriorate. In particular, greenhouse gas emissions lead to increasingly severe global climate changes, and the sustainable development of human society has been seriously threatened. Countries around the world have formulated their own energy development strategies to cope with the limitations of conventional fossil energy resources and environmental problems caused by development and utilization. Solar energy has become one of the most important renewable energy due to its reliability, safety, versatility, longevity, environmental protectio...
