Free Solar for
20 Years
Power tariffs were recently raised in Tamil Nadu
They will be raised every two years in future
The common area lighting and water pump is now charged commercial rates
With such high tariffs, rooftop solar is an increasingly viable solar option
The panel costs Rs 60,000 per kilowatt; can
produce
4 units of power every day
Subsidy is available for residential houses but not for apartments or their common areas
On-grid solar has no battery backup
If there’s no power supply from EB, solar system will also not supply. When sun sets, EB power will be automatically taken
You can send solar power back to EB line and get paid for it through a net-in meter
But charges for using government’s network to supply power will be deducted
Off grid has battery backup. If EB power is not there, the batteries can keep supplying
In three-five years, the initial investment will pay back
After that users can get free solar power for another 20 years from same panel
The solar panel vendor will get approvals and clearances from electricity board
Selecting the right vendor is key to having a good solar power system
Please check out vendors with their previous customers before deciding
