25.0 KVA ON-GRID SOLAR PV MODULE:
1.0
1.1
Introduction :
The grid-connected solar photo-voltaic (PV) systems, solar energy is fed into the
building loads that are connected to the TANGEDCO 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 the energy consumption of the building. This surplus is fed into the grid.
During the night, or when during the day energy demand in the building exceeds solar
energy generation, energy is drawn from the grid. Grid connected solar PV systems
have no battery storage and will not work during grid outage. For buildings with
grid connected 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 connected solar PV system consists of the solar panels, solar panels mounting
structure, one or more grid inverters, protection devices, meters, interconnection
cables and switches.
Components and parts used in solar PV systems should conform to the BIS or IEC or
other international specifications, wherever such specifications are available and
applicable.
Quality and Workmanship :
Solar PV modules are designed to last 25 years or more. It is therefore essential that
all system components and parts, including the mounting structures, cables, junction
boxes, distribution boxes and other parts also have a life cycle of lat least 25 years.
Therefore, all works shall be undertaken with the highest levels of quality and
workmanship. During inspection special attention will be given to neatness of work
execution and conformity with quality and safety norms. Non compliant works will
have to be redone at the cost of the installer.
System sizing :
As per the solar net metering orders of the Tamil Nadu Electricity Regulatory
Commission (TNERC) of 13.11.2013, crediting of energy for the purpose of net
metering is limited to 90% of the consumed energy during a 12 month settlement
period. The maximum recommended solar PV capacity for grid connected solar PV
systems is therefore a capacity that produces not more than 90% of the annual energy
consumption of the building.
