REVERSE POWER RELAY for solar PV systems
- 1. Reverse Power Relayfor Solar PV systems Guided by, Dr.T.Bogaraj, Assistant Professor, PSG College of Technology Done by, C.Balaji 15E105 J.Karthickraja 15E117 S.Praveenkumar 15E137 S.Boopalan 16E402.
- 2. Problem statement Toavoid transmitting the excess power from solar, back to the grid when the load is less (especially during weekends) so as to reduce excess tariff.
- 3. Reverse power Thepower developed by the solar panel is supplied to the load via power house where the EB meter is running When the excess amount of power is generated , it is returned to the electric grid and the power is transferred.
- 4. Why Net meteringis not used? Advantage of Net metering is that when the reverse power is generated , the meter reading gets reversed for the return power supplied to the grid But in TamilNadu , it is not yet implemented Hence, the better way is to turn off the inverters.
- 6. What is theproblem? When the excess power gets reversed in the solar panel to the grid. EB meter reading gets accounted during this time. Since there is no net metering practice. So the power supplied to the grid,from the solar is considered as it is drawn from the grid itself. So tariff is increased.
- 7. Solution To avoidthis and make it as a cost efficient, inverter can be turned off when the excess power is generated and also net metering can be used.
