Control the Future, Invent it
Energy Efficiency
• As India develops, the per capita electricity
consumption would go up drastically
• Motors accounts for 60 ~ 65% of the total electricity
consumption
• Energy efficiency/renewable energy programs must
address electric motors.
• In countries like India with huge infrastructure
constraints, it makes more sense to focus on using the
existing resources more efficiently
Existing Rooftop Solar Systems
PV

Controller
Inverter
Lights &
Fans
• Uses existing appliances, which are inefficient
• Motorised loads like AC, Fridge, etc., are not included
• Battery charge controller & Inverters are needed
• Loss of efficiency could be significant (as much as 30%)
• Battery maintenance & Replacement cost are important issues
• Overall cost is quite high
• Rooftop area required is also high
Present Solution - Issues
Inverter
Micro Wind
Micro Hydel
Bio Gas Generator
Grid
Air Conditioner
Refrigerator
Ceiling Fan
Submersible Pump
LED Lights
Battery Bank
Solar Panel
The New Solution
• Use of Super Efficient Appliances
• All appliances operate directly from DC
or AC
• Soft starting - no starting current
• No Inverter
• No battery, unless critical backup is
needed
New Solution - Key Features
• Central Grid Controller (CGC), iGrid, monitors the power
available in the panels and also the load requirements so that:
• All the appliances run from DC when sunshine is available
• In case of cloudy conditions, maximum power available in
the panels is used
• When sunshine is not there, the appliances run from the
utility mains
• When excess power is available in the panels, the same can
be fed back to the grid thru a Grid Tie Inverter
iGrid - Features
• No costs when sunshine is available
• When running from AC Mains, the following advantages
accrue:
• The power bill comes down by at least 50%
• The power factor is near unity for all the appliances -
tariff incentives can be availed of
• Wide voltage fluctuations in the input supply voltage are
permissible - 100/150 V ~ 270 V (No stabilisers are
needed)
• Credits from the EB for excess power fed back to the grid
