  • There is up to 40% subsidy on solar for hybrid & on-grid solar systems. No subsidy is available for off-grid solar systems.

You will get the delivery within 10 days from the date of order & installation within 10 days from the date of delivery.

#6. Subsidy on Solar System

Increasing the production of solar electricity, the dependency and depletion of other limited natural resources used to generate electricity, can be reduced. And hence, the government of India helps people financially to install solar systems using the MNRE solar subsidy scheme. The subsidy rates are:

 Please note: 

  • There is no subsidy scheme applicable on a solar system having capacity greater than 10kW.

  • These subsidy rates may vary according to your state solar policy and your location.

Expert Advice

“If you plan to install a 40kW solar system, we recommend installing an on-grid solar system (subject to power outages).” A 40kW on-grid system is less expensive than other types of 40kW systems; additionally, solar net-metering is available for this system.”

However, if the grid electricity in your area is unreliable and frequently goes out for more than two hours, then you must consider an off grid solar system or a hybrid solar system.
