Delhi Solar Policy

The rooftop space available for solar panels in Delhi is projected to be 31 square kilometres, giving the city a solar energy potential of 2500 MWp (annual Generation approx. 3,500 million kWh). This potential exists in the government/public sector at 26%, the commercial/industrial sector at 25%, and the residential sector at 49%.

Delhi is well-positioned to lead India's rooftop solar revolution and has set solar generating goals of 1000 MW by 2020 (4.2% of energy consumed) and 2000 MW by 2025 (6.6% of consumed energy).



Before commissioning solar plants with a capacity greater than 200 kWp, they must be inspected by an Electrical Inspector appointed by the Government of Delhi to assure quality, safety, and compliance. Prior to commissioning, the consumer is responsible for inspection and verification of solar plants with capacities up to 200 kWp.

You will receive an incentive of Rs. 2.00 per unit for the gross energy generated by your rooftop system. The minimum eligibility requirement for GBI will be 1,100 solar energy units (kWh) per kWp per year. The GBI facility will not apply to solar facilities that generate less than 1,100 units (kWh) per kWp per year. The annual solar energy production qualifying for GBI is set at 1,500 kWh per kWp, regardless of the solar generation metre readings. GBI Applicability is for three years from the date "Delhi Solar Energy Policy, 2016" went into effect, which was August 3, 2016; and it is applicable on a first-come, first-served basis.

As 40% Accelerated Depreciation is permitted in the first year of a solar system's life, commercial and industrial customers can benefit from the Depreciation tax shield.

Regarding Net Metering:


Before installing Net Meters, DISCOMS will do an inspection and verification of safety-related procedures. The consumers will assist the DISCOMS with this verification.

Capacity Limits under Net-Metering Arrangement: Minimum 1kWp, Maximum 1000 kWp.

Under the net-metering setup, the solar system capacity allowed as a percentage of sanctioned load is one hundred percent.


The total capacity of all solar systems installed in a particular area of Delhi cannot exceed 15 percent of the capacity of the Local Distribution transformer in that region.

At the end of the fiscal year, any extra generation (over 90 percent) would be considered free energy and not offset against the consumer's usage. There shall be no carryover to the following fiscal year.


Steps to go solar in Delhi: Solarization in Delhi is a straightforward three-step process: 1. Schedule a site survey on our site survey page (https://www.bigwitenergy.com/callback-request) for your residential, business, or industrial property. You may choose any date for the survey, excluding public holidays.

2. Following the survey, we will provide you with a Bigwit Energy proposal that focuses on maximising your solar investment returns and maximising the use of your rooftop as you go solar. Our Bigwit Energy solar consultant will walk you through this proposal in great detail, and after you're satisfied and have signed the EPC contract, we'll begin construction.

3. With all agreements in place, it will take us approximately four to six weeks to finish the installation at your location. You will now have a solar system installed on the rooftop of your home and save up to 80 percent on your electricity costs.
