the unique mounting of PVNB, such systems provide better land utilization ratios for energy production than conventional solar PV farms. Because of reduced racking costs PVNB is one of the cheapest ways to implement large scale grid-connected PV installations. There is now ample evidence that a wide range of PVNB systems work.
