What Is the Delhi Solar Portal?

The Delhi Solar Portal is the online platform of the Energy Efficiency and Renewable Energy Management Centre under the Department of Power, Government of NCT of Delhi.

It provides information and online services related to rooftop solar installations in Delhi, including:

• Rooftop solar subsidies
• PM Surya Ghar applications
• Delhi state subsidy
• Generation-based incentives
• Empanelled solar vendors
• Solar installation models
• Capital subsidy status
• Solar rooftop calculator
• Consumer services and grievances
• Community solar
• Group net metering
• Operation and maintenance information

The portal was updated on September 24, 2026, and currently states that the Delhi Solar Muft Bijli Yojana closes on February 28, 2027.

What Is the PM Surya Ghar Rooftop Solar Subsidy?

The PM Surya Ghar: Muft Bijli Yojana provides central financial assistance to eligible residential consumers installing rooftop solar systems.

According to the current Delhi Solar Portal, the central subsidy for residential households is:

Solar Capacity	Central Subsidy
Up to 2 kW	₹30,000 per kW
Additional capacity from 2 kW to 3 kW	₹18,000 per kW
Systems above 3 kW	Maximum ₹78,000

This means that a qualifying residential consumer can receive a maximum central subsidy of ₹78,000 for a rooftop solar installation.

Example

For a 3 kW system:

• First 2 kW × ₹30,000 = ₹60,000
• Additional 1 kW × ₹18,000 = ₹18,000
• Total central subsidy = ₹78,000

A system larger than 3 kW does not receive a higher central subsidy because the residential central subsidy is capped at ₹78,000.

Delhi State Solar Subsidy 2026

In addition to the central financial assistance, the Delhi Solar Energy Policy provides a state capital subsidy for residential consumers.

The current Delhi Solar Portal states that residential consumers are eligible for:

₹2,000 per kW, subject to a maximum of ₹10,000 per consumer.

The state subsidy is passed through the consumer’s first electricity bill after commissioning of the rooftop solar system.

Therefore, eligible residential consumers may potentially receive both:

• Central subsidy under PM Surya Ghar
• Delhi state capital subsidy

The exact amount applicable to an individual installation should be checked through the official portal and applicable scheme rules before installation.

Generation-Based Incentive for Delhi Solar Consumers

Delhi’s solar policy also provides a Generation-Based Incentive (GBI) based on the electricity generated by a rooftop solar system.

For residential consumers, the current Delhi Solar Energy Policy information lists:

Consumer/System Category	Generation-Based Incentive
Residential systems up to 3 kW	₹3 per kWh
Residential systems above 3 kW and up to 10 kW	₹2 per kWh
GHS/RWA systems up to 500 kW	₹2 per kWh
Commercial & industrial consumers for the first 200 MW deployed	₹1 per kWh

The Delhi Solar Portal states that the policy provides these generation-based incentives in addition to the applicable central financial assistance and state capital subsidy.

The GBI should not be confused with the upfront capital subsidy. The capital subsidy reduces the initial installation cost, while the GBI is linked to solar electricity generation.

How Much Rooftop Space Is Required for Solar in Delhi?

The Delhi Solar Portal’s solar calculator estimates that approximately 10 square metres, or about 100 square feet, of rooftop area is required for a 1 kW solar plant.

However, the actual usable area can vary because rooftops may contain:

• Water tanks
• Parapets
• Staircase structures
• Antennas
• Other equipment
• Areas affected by shade

The portal notes that rooftop utilisation may initially be around 20% in some cases and can potentially be increased with elevated structures.

Approximate Space Requirement

Solar System	Approximate Area
1 kW	100 sq ft
2 kW	200 sq ft
3 kW	300 sq ft
5 kW	500 sq ft

These are broad planning estimates rather than guaranteed installation requirements. A solar vendor should conduct a site assessment before finalising the system size.

How Much Does Rooftop Solar Cost in Delhi?

The Delhi Solar Portal’s calculator currently uses approximate installation costs of:

• ₹60,000 per kW for systems up to 5 kW
• ₹55,000 per kW for systems from 6 kW to 10 kW
• ₹50,000 per kW for systems above 10 kW

Actual quotations can differ depending on equipment, roof structure, installation requirements, wiring, inverter specifications, metering and other project-specific factors.

For example, a 3 kW installation using the portal’s indicative ₹60,000-per-kW figure would have an approximate gross installation cost of ₹1.80 lakh before applicable subsidies.

The actual amount payable after subsidies should be calculated using the applicable scheme rules and the vendor’s final quotation.

Who Can Benefit From Rooftop Solar in Delhi?

Rooftop solar can be relevant to several categories of consumers.

1. Individual Homeowners

Homeowners with suitable shadow-free roof space can install a rooftop solar system under the applicable residential scheme.

2. Apartment Residents

People living in apartments may not always have individual roof rights or sufficient rooftop space. Delhi’s solar policy provides alternative models such as community solar and group-based arrangements.

3. Group Housing Societies and RWAs

Group Housing Societies and Resident Welfare Associations can install solar systems for common facilities and may also qualify for applicable central subsidy support.

4. Consumers With Limited Roof Space

The Delhi Solar Portal specifically provides information on community solar for consumers who do not have suitable rooftop space, including tenants and apartment dwellers.

Rooftop Solar Subsidy for RWAs and Group Housing Societies

The PM Surya Ghar subsidy structure also provides support for Group Housing Societies and Resident Welfare Associations.

The Delhi Solar Portal currently lists central financial assistance of:

₹18,000 per kW for common facilities, including EV charging, up to 500 kW capacity at 3 kW per house, subject to the applicable upper limit and scheme conditions.

This can make rooftop solar particularly relevant for common-area electricity consumption in apartment complexes and housing societies.

RWAs should verify the current eligibility criteria and applicable installation model before proceeding.

Delhi Solar Portal: How to Apply for Rooftop Solar Subsidy in 2026

The application process involves several stages.

Step 1: Check Your Electricity Consumption

Start by reviewing your monthly electricity consumption.

The Delhi Solar Portal provides indicative system-size recommendations based on average monthly consumption:

Average Monthly Consumption	Suggested Solar Capacity
0–150 units	1–2 kW
150–300 units	2–3 kW
More than 300 units	Above 3 kW

These are indicative recommendations; the final system size should also consider available roof area and other technical factors.

Step 2: Check Your Rooftop

Determine whether you have sufficient shadow-free rooftop space.

Check for:

• Shade from neighbouring buildings
• Water tanks
• Trees
• Parapets
• Staircases
• Existing rooftop equipment

The solar calculator on the Delhi Solar Portal can be used to estimate feasible system capacity based on electricity consumption and available rooftop area.

Step 3: Apply Through the Solar Portal

Eligible consumers can begin the rooftop solar application process through the Delhi Solar Portal.

For the PM Surya Ghar scheme, applications are submitted through the National Portal at pmsuryaghar.gov.in. The Delhi Solar Portal provides the relevant application route.

Applicants should keep their electricity consumer details and other required information ready before starting the application.

Step 4: Select an Eligible Solar Vendor

Consumers applying under PM Surya Ghar must select a vendor empanelled under the PM Surya Ghar portal to claim the central subsidy.

The Delhi Solar Portal provides separate vendor links for Delhi’s distribution areas, including BRPL, BYPL, TPDDL, NDMC and MES.

Before finalising a vendor, consumers should compare:

• System capacity
• Solar panel specifications
• Inverter specifications
• Warranty
• Installation cost
• Maintenance terms
• Metering arrangements
• Expected generation
• Subsidy-related documentation

Step 5: Site Survey and Installation

After vendor selection, the rooftop is assessed for installation feasibility.

The vendor determines the appropriate system design and proceeds with installation after the required approvals.

Consumers should carefully review the quotation and agreement before installation.

Step 6: Inspection and Commissioning

Once the rooftop solar system has been installed, the required inspection, metering and commissioning procedures are completed through the applicable DISCOM and scheme process.

Consumers should retain all documents, invoices, approvals and warranties.

Step 7: Track Your Subsidy

Delhi residents can use the Capital Subsidy Status section of the Delhi Solar Portal to check whether their capital subsidy has been released.

The portal allows consumers to search using their Consumer Account (CA) Number.

What About Solar for Apartments and Tenants?

One of the important developments in Delhi’s solar policy is that consumers without suitable individual rooftops are not necessarily excluded from solar adoption.

The Delhi Solar Portal describes a Community Solar Model for consumers who do not have suitable roof space, including:

• Tenants
• Apartment residents
• Consumers with small rooftops
• Consumers with shaded rooftops

Under this model, consumers can purchase a share of a third-party-owned solar photovoltaic system, subject to the applicable framework.

The portal also provides information on other models, including:

• Community Solar
• Group Net Metering
• RESCO
• Hybrid RESCO
• CAPEX

These options allow consumers with different financial and rooftop constraints to explore different ways of adopting solar power.

CAPEX vs RESCO: Which Solar Model Applies?

Delhi provides multiple pathways for rooftop solar adoption.

CAPEX Model

Under the CAPEX model, the consumer purchases the solar system and becomes its owner.

This model is generally relevant for consumers who:

• Have suitable roof space
• Can afford the upfront investment
• Want to own the solar system

The Delhi Solar Portal states that consumers can purchase the system from a solar vendor and sell excess electricity to the grid according to the applicable framework.

RESCO Model

Under a RESCO arrangement, a third-party solar developer owns and operates the system under the applicable agreement.

This can provide an alternative for consumers who may not want to make the entire upfront investment.

Community Solar

Community solar is designed for consumers who may not have suitable individual rooftop space.

Delhi’s solar portal specifically identifies tenants and apartment dwellers among potential users of this model.

How Much Can You Save With Rooftop Solar?

The actual savings from rooftop solar depend on several factors, including:

• System capacity
• Electricity consumption
• Solar generation
• Rooftop orientation
• Shading
• Electricity tariff
• Net-metering arrangements
• Applicable subsidy
• Generation-based incentive
• Maintenance costs

Therefore, there is no single savings figure that applies to every Delhi household.

The Delhi Solar Portal provides a Solar Rooftop Calculator that estimates:

• Feasible rooftop solar capacity
• Installation cost
• Central subsidy
• State subsidy
• Effective cost
• Monthly generation-based incentive
• Monthly electricity-bill savings
• Estimated monthly benefits
• Payback period

Consumers should use the calculator as an estimate rather than treating its output as a guaranteed financial return.

Rooftop Solar and Electricity Bills

One of the major reasons households consider rooftop solar is the potential reduction in electricity purchased from the grid.

The Delhi Solar Portal highlights rooftop solar as a way to reduce electricity consumption and electricity bills. It also identifies generation-based incentives and energy independence among the benefits of rooftop solar adoption.

However, the actual electricity bill after installation depends on consumption patterns, solar generation, applicable tariff structure and the treatment of exported electricity.

Is Operation and Maintenance Included?

Consumers should pay close attention to maintenance terms when selecting a vendor.

For PM Surya Ghar installations, the Delhi Solar Portal states that the vendor responsible for installation will provide cleaning and all-inclusive operation and maintenance for five years, including rectification of faults or issues at the vendor’s cost, subject to the applicable scheme conditions.

Consumers should also retain documentation relating to:

• Solar panel warranties
• Inverter warranty
• Installation warranty
• O&M agreement
• Equipment specifications
• Bills and invoices

The portal notes that solar panels typically have long-term warranties, while inverter warranties are generally shorter.
