2KW , 3KW and above will increase proportionally

No. This is On Grid system which does not require any battery storage system. If you produce solar energy more than you consume it will automatically go to APDCL grid. If you produce less than demand then APDCL grid will directly provide extra electricity. There is no need and use of storage. 

No. Solar System will shut down during APDCL power outage. This is done keeping safety of lineman and other people and systems. If a lineman is working on the line and for his safety APDCL cut the power but Solar System provides power to the grid then lineman safety is compromised.

Units supplied by consumer to APDCL will be deducted from units supplied by APDCL to consumer. This will be carry forwarded to subsequent month if unit supplied by consumer to GRID is more than unit supplied from GRID to consumer.
