City-Wise Example: How Cost Changes for Different Homes
Multiple city-specific factors make up the cost of solar systems in India. All states provide some level of subsidy under PM Surya Ghar, but many states also offer additional benefits that decrease the price of solar systems for homeowners. For instance, states such as Gujarat and Uttar Pradesh offer state-level support, making solar systems significantly cheaper in cities such as Ahmedabad and Lucknow.
In addition, local market conditions have a significant impact on the price of solar systems. Cities with many solar EPC (engineering, procurement, and construction) companies and manufacturers usually have lower prices because there is more competition. Likewise, cities that are more metropolitan cities generally have higher installation and labour costs due to the higher cost of living in those locations. The transportation of solar panels and equipment, the ease of net metering, and local regulations are additional factors that impact the overall price of a solar system installation.
Indicative Cost for a 3 kW On-Grid Solar System (Before Subsidy)
| Ahmedabad around ₹2,05,000 |
|---|
| Lucknow around ₹2,10,000 |
| Jaipur around ₹2,25,000 |
| Bengaluru around ₹2,35,000 |
These prices are approximate and may vary depending on system quality, roof conditions, and installer charges.
Hidden Costs That Homeowners Should Know
Switching to solar is a smart long-term investment that reduces electricity bills and protects you from rising tariffs. But many installers offer low upfront prices that hide extra charges later. At Solar Sunyield, we believe in full transparency. Here are the common hidden costs and how we help you avoid them.
- For a lot of homes, upgrading the switchboard (switchboard replacement) and wiring can be a major expense. Most contractors will add this expense to your bill after the fact. Our company does an upfront assessment of your entire system to take away the shock of this expense later.
- Another common problem after the installation is often leaking roofs from either old roofs or weak roofs. We inspect the roof very thoroughly to ensure it is 100% secure prior to signing off on the installation.
- While renewable energy panels are rated to last 25 to 30 years, renewable energy inverters have a life expectancy of approximately 8 to 12 years. We will help you plan for the future replacement costs associated with an inverter.
- Many renewable energy companies charge monthly app or cloud fees for monitoring their systems. With our service, monitoring is free, and you will never receive recurring monitoring fees.
- Additional hidden charges are often added when it comes to approvals, engineering drawings, and submissions. Every one of our systems includes all the NEM paperwork and TNB permitting.
- Most inexpensive installation services offer very poor customer service. We also offer a 5-year workmanship warranty and provide ongoing support at no additional charge.
- Some installers cut their costs by using weak rails, smaller cables, and unsafe connectors. We do not substitute generic products for any materials that are specified in a contract.
- If the installation process damages any materials, most installers will not cover it. We provide complete site insurance and workmanship coverage for our customers’ peace of mind.
Solar Panels for Home Cost vs Savings: Simple Payback Guide
Solar panels help reduce electricity bills by converting sunlight into electricity for your home. When you use solar power during the day, your dependence on grid electricity drops, which directly lowers your monthly power bills.
One of the biggest advantages is net metering. Any extra electricity generated by your solar panels is sent back to the grid, and you receive credits that reduce future bills. Solar power also helps you save during peak hours, as most generation happens when grid electricity is costliest.
ROI and Payback Period
Most homeowners recover their solar investment within three to four years. For example, a three-kilowatt solar system costing around ₹1,30,000 can save nearly ₹3,000 per month, allowing you to recover the cost in about three and a half years. After this, the system continues to generate savings for more than two decades.
Factors That Affect Solar ROI
• Initial system cost and available subsidy
• Electricity tariff increases over time
• System performance and regular maintenance
• Daily usage patterns and roof sunlight exposure
Long-Term Financial Benefits
Once the payback period is complete, every unit of electricity generated becomes pure savings. Solar protects you from future tariff hikes, requires very low maintenance, and improves your property’s resale value.
How to Maximise Your Solar Savings
• Select the correct system size based on actual usage
• Use energy-efficient appliances to reduce overall load
• Keep panels clean and schedule periodic servicing
Subsidy on Home Solar Systems in India
Under the PM Surya Ghar: Muft Bijli Yojana, homeowners installing rooftop solar systems can receive substantial financial support. The Central Financial Assistance (CFA) is credited directly to the consumer’s bank account through Direct Benefit Transfer (DBT), making solar more affordable than ever.
Central Subsidy Structure
| Ahmedabad around ₹2,05,000 | Ahmedabad around ₹2,05,000 |
|---|---|
| Up to 2 kW | ₹30,000 per kW |
| 3 kW | ₹78,000 total |
| Above 3 kW | ₹78,000 (fixed subsidy) |
The subsidy is calculated on the lower of the panel capacity or the inverter capacity. This central subsidy significantly reduces the upfront cost of installing solar panels at home.
But that’s not all, many Indian states also offer additional top-up subsidies, and new rules for MSMEs, schools, housing societies, and agricultural consumers are being introduced gradually.
State-Wise Solar Subsidy in India
Several states offer extra financial support on top of the central CFA, making solar energy even more cost-effective:
| State | Top-Up Benefits |
|---|---|
| Delhi | ₹10,000 per kW up to 3 kW (maximum ₹30,000) |
| Uttar Pradesh | ₹15,000 per kW (max ₹30,000) in addition to central subsidy |
| Maharashtra | Over 2.5 lakh installations; ₹1,870 crore subsidy disbursed. Strong support for housing societies |
| Gujarat | One of the highest adopters; ~3 lakh beneficiaries and ₹2,362 crore subsidy given |
| Haryana | Offers CFA plus added support for Antyodaya families and Model Solar Village projects |
These state subsidies may be time-bound, meaning they depend on availability and active government programs.
Roof Check Before You Install Solar Panels
Investing in Solar Energy is a great Investment Choice for both the Ecosystem and your Wallet! Before your New Solar Panels are installed, it is critical to verify that you have a Good Roof to support the Solar System Efficiently for many Years to come.
Finally, evaluate how much roof area there is and how strong the roof structure is. There should be ample amounts of flat stable surfaces to mount your solar panel or solar water heaters, as well as ample amounts of support for the weight of the solar panels and mounting equipment. Superior Solar Systems employs qualified solar technicians to inspect your roof space and assist with your installations.
How to Choose the Right Solar System for Your Home
Choosing the right solar panel system for your home is essential to maximise energy savings, ensure long-term performance, and get the best return on investment. Here’s a clear, short guide based on key industry recommendations:
How to Choose the Right Solar System for Your Home
The solar installation process begins with a site survey where installers check your roof’s direction, angle, shading, and strength.
