Technical Specification




17. Technical Specifications of Grid SPV Power Plant

17.1 Introduction :

In grid-tied Solar Photo-Voltaic (SPV) systems, solar energy is fed into the building loads that are connected to the public electricity grid through a service connection with surplus energy being fed into the grid and shortfall being drawn from the grid. Production of surplus energy may happen when solar energy produced exceeds building load energy demand. This surplus is fed into the grid. During the night, or when during the day energy demand in the building exceeds solar energy production, energy is drawn from the grid. Grid-tied solar PV systems have no battery storage and will not work during grid failure. For buildings with grid-tied solar PV systems, the service connection meter needs to be of the bidirectional type, whereby import KWh and export KWh are separately recorded.

A grid-tied Solar Photo Voltaic (SPV) power plant consists of SPV array, Module Mounting Structures, Solar Grid Inverter (SGI), control and protection devices, circuit breakers, interconnection cables and switches.

Components and parts used in the SPV power plants shall conform to the BIS or IEC or other international specifications, wherever such specifications are available and applicable.
