Irregular photovoltaic roofing system with a flashing piece

A photovoltaic array comprising: three or more overlapping rows of photovoltaic modules wherein at alternating ends, adjacent rows of photovoltaic modules are interconnected by a row-to-row flashing piece wherein a first row of photovoltaic modules extend a distance beyond a second row of photovoltaic modules and a third row of photovoltaic modules and the second row of photovoltaic modules is incommunication with one or more flashing components that extend the second row of photovoltaic modules at least the distance that the first row of photovoltaic modules extend. 种光伏阵列，包括：三行或更多行重叠的光伏模块；其中，在交错的端部，相邻行的光伏模块通过行间防水片相互连接，其中，第行光伏模块延伸超过第二行光伏模块和第三行光伏模块距离，并且第二行光伏模块与个或多个防水部件相连通，该个或多个防水部件将第二行光伏模块至少延伸第行光伏模块所延伸的距离。
