Best Solar Company in Delhi Providing Reliable Rooftop Solar Systems

Installing solar in Delhi is a practical solution to rising air pollution. A rooftop solar system can offset thousands of kilograms of carbon emissions over its 25-year operational life.

From a financial perspective, the solar panel installation cost in Delhi is recovered within 3-5 years. After this payback period, the system generates free solar electricity for the rest of its lifespan. As a result, homeowners can enjoy zero or near-zero electricity bills for over two decades, leading to substantial solar savings and ROI.

Here’s how much money you can save from an on-grid solar system if you choose SolarSquare as your Delhi solar power installation company:

• 3 kW solar panel price in Delhi with subsidy: ~Rs. 1.17 lakh*
• Savings from a 3 kW solar system over 25 years with SolarSquare as your Delhi solar company: ~Rs. 7.13 lakh*
• Return on investment (ROI): ~5.1x

*Please note: The above-mentioned cost of installing an on-grid solar plate in Delhi is indicative as of 20th April 2026 for the SolarSquare Blue 6ft variant. The final solar plate price in Delhi depends on your DISCOM charges, city, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc. Prices are subject to change. Also, while calculating savings from solar installation in Delhi, we have considered an annual tariff escalation of 3% and an annual plant degradation rate of 1%. The actual final savings from solar in Delhi depend on the types of solar panels you’ve installed and their efficiency, intensity of sunlight your rooftop receives, orientation of the panels and tilt angle, the pollution level and weather conditions in your city, the temperature, shadow on the roof, impact of dirt/dust, and how well you maintain your panels after installation.

Investing the same ~Rs. 1.17 lakh on gold or mutual funds will result in much lower savings and ROI over 25 years when compared to the solar savings from a 3 kW rooftop solar panel system for homes in Delhi. Moreover, electricity tariffs in India rise by 3-6% every year. So, will you save ~Rs. 7.13 lakh over 25 years by going solar today, or spend all that money on paying hefty bills for the rest of your life? Think about it.

Rooftop solar is a long-term asset, and choosing the right solar companies in Delhi NCR ultimately reduces long-term risk. A DISCOM-approved solar company in Delhi, such as SolarSquare, with over a decade of installation and maintenance experience across India, offers the strongest assurance of long-term reliability.

SolarSquare is, in fact, the #1 solar installation company in Delhi, in terms of the number of installations, with 2,881 kWp installed across 617 properties as of 20th April 2026, as listed on the PM Surya Ghar Muft Bijli Yojana National Portal.

It’s critical that the rooftop solar system providers in Delhi NCR you choose today last for as long as the PV system does because solar requires regular maintenance to perform as expected over time. Without proper care, the savings deplete over time because power generation drops.

Why Choose SolarSquare as Your Solar Installation Company in Delhi?

SolarSquare installs rooftop solar systems in Delhi with a focus on output accuracy, structural durability, and long-term system accountability. Every installation follows defined BIS engineering standards and a savings guarantee with a money-back promise.

We’re the #1 solar system company in Delhi, based on the number of solar installations we’ve completed. As of 20th April 2026, we have already installed 2,881 kWp of rooftop solar systems across 617 properties in Delhi as listed on the PM Surya Ghar Muft Bijli Yojana National Portal.

We have more than ten years of rooftop solar installation experience across India. This experience has taught us that material selection, structural design, and maintenance are the three pillars that ensure a rooftop solar system lasts for 25 years, even during cyclones.

Let’s find out why more than 12,000 customers across India have rated SolarSquare 4.8 on Google.

#1. 99.91% Storm-Safety Record

Rooftop solar panels loosening and dismounting during storms are commonly linked to inadequate mounting strength. Panels detach when mounting structures cannot absorb wind loads during high-speed storms and cyclones.

SolarSquare designs its installations in alignment with BIS engineering standards for structural safety. Over the past two years, our solar systems have had a 99.91% storm-safety record during severe cyclonic winds of up to 170 km/hr.

#2. WindPro Mount™ Mounting Structures With Cyclone-Grade Structural Design

All SolarSquare rooftop installations use WindPro Mount™, an IIT Bombay-approved mounting structure engineered to remain stable at wind speeds of up to 170 km/hr.

Here’s what makes our mounting structures so special:

• Approved by IIT Bombay for stability under cyclonic wind conditions up to 170 km/hr.
• Manufactured from premium virgin steel to reduce corrosion and material fatigue.
• Finished with an 80-micron hot-dip galvanized iron (HDGI) coating that preserves structural integrity beyond 25 years.

Furthermore, all the drilling we perform on the roof during installation is sealed using HILTI airtight chemical anchoring. This method prevents water seepage through the roof and adjacent walls caused by minor cracks after installation. In the rare event of a water leakage, we offer a one-year water-leakage warranty worth Rs. 1 lakh.

#3. Savings Guarantee with a Money-back Promise

Before every installation, we offer our customers an estimate of the expected power generation at their home. If the system we install produces fewer units than what we projected, we compensate you for the shortfall at Rs. 8 per unit.

This makes SolarSquare the first and only solar provider in India to offer a savings guarantee backed by a money-back promise.

#4. Five Years of Structured Rooftop Solar Maintenance

Solar panels perform as expected only when maintenance is consistent. To ensure that output does not decline over time, SolarSquare offers a 5-year annual maintenance plan with monthly scheduled service visits.

This maintenance coverage includes:

• Continuous remote monitoring to detect performance issues early.
• On-site technician visits for preventive checks and fault resolution.
• Professional panel cleaning using non-abrasive tools and solutions.
• Complete system inspections covering wiring, safety devices, mounting stability, and mechanical integrity.

Can you install a Solar System in Delhi on Loan?

Delhi solar power adoption among homeowners has increased in recent years due to easier access to solar financing. Banks and NBFCs offer dedicated solar loans, reducing the need for homeowners to arrange significant upfront capital for installation.

SolarSquare takes this help one step further by offering a zero-investment solar loan. This financing model eliminates the need for an initial out-of-pocket down payment.

Here’s how our zero-investment solar loan works:

• Zero initial out-of-pocket down payment needed: The government subsidy you are eligible for is applied directly to the total system price. This offsets the down payment, letting you start solar installation at your home without any out-of-pocket expense.
• EMIs designed around reduction in electricity bills: Monthly loan instalments are planned to remain close to the bill reduction you’ll observe after you go solar in Delhi. The amount previously paid to the utility provider is now redirected toward owning the solar system. This keeps your monthly budget undisturbed.
• Time-bound loan processing: Loan approvals are completed within 24 hours, preventing delays in project execution and installation.
• Multiple flexible loan repayment tenures: Loan repayment duration can be chosen between 6 months and 5 years. Shorter tenures close the loan sooner, while longer tenures distribute payments over time to reduce monthly installment pressure.

How Does an On-Grid Solar System in Delhi Work?

An on-grid solar system in Delhi works just like it does in any other part of the country. Solar panels capture solar radiation and convert it into electricity.

Here’s a step-by-step explanation of the entire process:

• Solar cells in solar panels absorb photons from sunlight: Photons are energy packets that, when absorbed, transfer their energy to electrons within the solar cells. The now-excited electrons leave their bonds and begin to flow in a single direction. This unidirectional flow of electrons is direct current (DC) power.
• DC power is converted to AC power: In India, homes cannot be supplied with DC, as it can be lethal. Therefore, a solar inverter first converts direct current (DC) into alternating current (AC), which is then sent to power your home.
• Solar net metering takes care of the billing: The DISCOM swaps a regular meter for a bidirectional net meter or a smart meter at your property once the solar system is installed. This meter tracks energy exchange between the grid and your solar system. For billing cycles where the solar system sends more energy to the grid than what it imports, the DISCOM gives you credits because you’re essentially supplying electricity to the grid. For cycles where your home draws more electricity from the grid than what your PV system exports, you pay the DISCOM for the additional grid units used at your home at the standard electricity tariffs in your city.

What are the Benefits of On-Grid Rooftop Solar Installation in Delhi?

Delhi is gripped by severe pollution, with the AQI deteriorating by the day. Installing a rooftop solar system is the most obvious answer to the challenge of rising pollution in Delhi. Moreover, an appropriately-sized solar system can lower bills by 90% or more, resulting in massive savings of tens of lakhs of rupees over 25 years.

Let’s have a closer look at all the benefits of solar panel installation in Delhi:

• It can reverse air pollution: Installing even a 1 kW solar plate in Delhi can offset ~26,000 kg of carbon emissions over 25 years. 39 full-grown trees achieve this same impact over the same time duration. Imagine how clean the AQI in Delhi could get if every home, housing society, and industry started using solar energy instead of grid power that comes from fossil fuels.
• It can lower electricity bills by 90% or more: When sized to meet your home’s energy needs, a rooftop solar system in Delhi can make your bills zero or near zero by covering all your energy needs without relying on the grid.
• It saves tens of lakhs of rupees over 25 years: With a rooftop solar system, you will no longer have to pay hefty bills throughout its operational life. This will lead to massive savings and ROI. For example, a 5 kW solar system that costs ~Rs. 2.22 lakh* in Delhi with subsidy can save ~Rs. 12.94 lakh* over 25 years, offering an ROI of ~4.8x.

*Please note prices are subject to change.  The above-mentioned solar panel price in Delhi with subsidy for on-grid solar systems is indicative as of 20th April 2026 for the SolarSquare Blue 6ft variant. The final cost of solar panel installation in Delhi depends on your DISCOM charges, city, product variant opted for, panel type, inverter type, mounting structure height, type of after-sales service, savings guarantee, roof height, etc. Also, while calculating savings from Delhi solar rooftop systems, we have considered an annual tariff escalation of 3% and an annual plant degradation rate of 1%. The actual final savings from rooftop solar in Delhi depend on the types of solar panels you’ve installed and their efficiency, intensity of sunlight your rooftop receives, orientation of the panels and tilt angle, the pollution level and weather conditions in your city, the temperature, shadow on the roof, impact of dirt/dust, and how well you maintain your panels after installation.

On-Grid vs Off-Grid Solar Panel for Homes in Delhi: Which is Better?

The choice between an on-grid and an off-grid solar system in Delhi depends on the consistency and availability of grid electricity supply in your area.

• When should you install an on-grid solar system? An on-grid PV system is connected to the local electricity grid. It does not use lead-acid or lithium batteries to store solar energy for later use. The absence of batteries keeps the overall system cost lower. This system is suitable for parts of Delhi where grid availability is stable and power outages are infrequent, making battery backup non-essential.
• When should you install an off-grid solar system? An off-grid PV system operates independently of the electricity grid. It includes a battery bank that stores excess solar energy generated during the day. This stored energy supplies power at night and during low-generation periods. Batteries increase the system cost but are necessary in locations where the grid is unreliable or unavailable. In these cases, stored solar energy provides continuous electricity without dependence on the grid.

The table below compares the two system types to highlight their differences clearly.
