Solar market in India is becoming extremely competitive with rapidly falling solar power tariffs. Ultimately it is putting immense pressure on module manufacturers and Solar PV balance of system (BoS) suppliers. BoS has been used as a very simplistic term to define the component requirements of a solar PV plant other than solar modules that roughly constitutes around 50 per cent of the project cost.

BoS refers to the components and equipment that move DC energy produced by solar panels through the conversion system which in turn produces AC electricity. Most often, BoS refers to all components of a PV system other than the modules. In addition to inverters and racking, this includes the cables or wires, switches, enclosures, fuses, ground fault detectors, and more. BoS applies to all types of solar applications like commercial, residential, agricultural, public facilities, and solar parks.
