Use Solar Panel & Appliances to Save on electricity bill, Electricity bills will increase every year by atleast 4%(Current Inflation Rate). Only way to cut the bill cost is by consuming less units.
The electricity is generated and Feed back to Electricity board line(where Electricity is not required to owner). While feeding back the Electricity billing meter will rotted in reverse direction (call negative billing).
When there is requirement of electricity to owner at day time , it will be shear by Solar panel
When owner is requiring electricity at night, the load will be sheared by Electricity Board line and Electricity billing meter will rotted in positive direction (call Positive billing).
