How much does solar cost for a home in India? What you actually pay for in 2026

If you have started looking at rooftop solar, you have probably seen prices that are all over the place. One company quotes a figure on the phone, another sends a WhatsApp image with "starting from", and a third says it cannot tell you anything until somebody visits your house. All three can be honest. Solar cost depends on things that are different for every roof, and most of the confusion comes from people comparing numbers that do not include the same things.

This guide explains what a home solar system really costs in India in 2026, what the price is made of, and how to work out whether it makes sense for your family. Where we use real numbers, they come from our own installations in Telangana and Andhra Pradesh, and we say so.

The short answer

A grid-connected rooftop system for a home usually costs between about ₹1.1 lakh for a small 1 kW system and about ₹6.4 lakh for a 10 kW system, before any government subsidy. Most homes we work with need somewhere between 3 kW and 5 kW.

To make that concrete, these are Origian Power's own gross price ranges (the full price, before any subsidy is taken off):

• 1 kW: ₹1,10,000 to ₹1,30,000
• 2 kW: ₹1,70,000 to ₹1,90,000
• 3 kW: ₹2,30,000 to ₹2,60,000
• 5 kW: ₹3,50,000 to ₹3,90,000
• 10 kW: ₹6,10,000 to ₹6,40,000

You will notice the price per kW falls as the system gets bigger. A 1 kW system works out to more than ₹1 lakh per kW, while a 10 kW system comes to roughly ₹61,000 to ₹64,000 per kW. That is not a discount trick. A lot of the work and material in an installation is the same whether the system is small or large, so it is spread over more kilowatts in a bigger system.

The rest of this article explains why the range exists, what you are paying for, and how to tell whether a quote is fair. For our full, current price list, see solar system prices.

Why one number never tells the whole story

When someone asks "how much does solar cost?", the honest answer is "for which roof, which equipment, and what is included?" Two quotes for "3 kW" can be very different systems.

Here is what usually changes from one quote to the next:

• The panel brand and model. Panels from established manufacturers cost more than unknown imports, and newer cell technologies cost more than older ones.
• The inverter. A grid-tied string inverter, a hybrid inverter with battery support, and a micro-inverter setup are priced very differently.
• The mounting structure. A low frame bolted flat onto a roof costs less than an elevated, galvanised structure that lets you use the terrace underneath and stands up to strong wind.
• Cabling and protection. Thin cables, cheap connectors and missing surge protection lower the price today and cost you later.
• Earthing and lightning protection. Some quotes include a proper separate earth pit and lightning arrestor. Some do not.
• The DISCOM paperwork. Feasibility, inspection and the net meter can be included or left for you to arrange.
• After-sales service. A maintenance visit every few months is a real cost to the installer. If it is "free", ask what it actually covers.

So before you compare prices, make sure you are comparing the same things. A cheaper quote that leaves out earthing, net metering and maintenance is not cheaper. It is incomplete.

What is inside the price of a rooftop system

It helps to know what you are actually buying. A typical grid-connected home system has these parts.

Solar panels

The panels are the most visible part and usually the largest single item. Their price depends on the brand, the cell technology (for example mono PERC, TOPCon or bifacial) and the wattage per panel. We explain the technologies in our guide to types of solar panels.

The panels we install come from Renewsys, Adani, Waaree and Tata, with a 10-year product warranty and a 25-year performance warranty.

The inverter

The inverter turns the direct current (DC) the panels produce into the alternating current (AC) your home uses. For a normal grid-connected home, this is a string inverter. If you want battery backup, it is a hybrid inverter, which costs more. We use Growatt, Solis and Goodwe inverters, which typically carry 5 to 10 years of warranty depending on the brand.

The mounting structure

This is what holds the panels on your roof, and it matters more than most people realise. A structure has to survive 25 years of sun, rain and wind. Ours are hot-dip galvanised steel, rated to 150 km/h wind, fixed with stainless steel bolts, and raised on flat roofs at a 10 to 15 degree tilt. Cheaper structures save money at the start and can rust or loosen within a few years.

Cables, connectors and switchgear

DC cables run from the panels to the inverter, and AC cables run from the inverter to your distribution board. Connectors join the panels together. Distribution boxes (a DC box and an AC box) hold the protection devices. This is where many low quotes cut corners, because most buyers never look at a cable.

Earthing and surge protection

A rooftop system is a large metal structure on the highest point of your house. It needs proper earthing and lightning protection. We use a dedicated lightning-arrestor earth in its own separate pit, copper earth cable bonding every frame, and surge protection on both the DC and AC sides. Our guide to solar earthing and lightning protection explains why each part matters.

The DISCOM process and net meter

To export surplus power and get credit for it, your system needs DISCOM approval and a bidirectional (net) meter. This involves a feasibility application, an inspection and the meter change. Some installers charge separately for this. In our installations, the net metering application and DISCOM coordination are part of the quoted price.

Installation labour and transport

Getting materials to your roof, mounting the structure, wiring, testing and commissioning all take skilled people and time. A careful installation of a home system usually takes a few days of actual work, inside a longer timeline set by approvals.

After-sales service

Panels need cleaning, connections need checking, and faults need someone to come out. We schedule maintenance visits every three months and commit to responding within 48 hours when a customer reports an issue. Ask any installer to put their after-sales commitment in writing.

What makes your price higher or lower

Once you know the parts, the reasons for different prices become clearer.

System size

This is the biggest factor. Size should come from your electricity use, not from a package. A family using about 300 units a month needs a very different system from one using 800.

A useful rule of thumb from our own installations in the Anantapur region: each kW of solar produces roughly 1,550 to 1,600 units (kWh) a year. A 3 kW system averages about 400 units a month, and a 5 kW system about 650 units a month. Your actual output depends on shading, orientation and how clean the panels are. Our article on how many units a solar system generates in Telangana and Andhra Pradesh goes through this in detail.

Your roof

A flat, open terrace with no shade is the easiest and cheapest roof to work on. Sloped roofs, sheet roofs, high buildings, long cable runs and shading from water tanks or neighbouring buildings all add work or material.

Equipment choices

Premium panels, a hybrid inverter or batteries all raise the price. Batteries in particular can add a large amount, because they are the part of the system that needs replacing during its life. Our guide to solar battery prices and lithium vs lead-acid explains when they are worth it.

Structure height

If you want to use your terrace for drying clothes, sitting or storage, an elevated structure costs more than a low one, but it gives you the space back.

What is included

Earthing, surge protection, net metering, maintenance visits and a workmanship warranty are not optional extras in a good installation. But some quotes leave them out to look cheaper.

How the PM Surya Ghar subsidy fits in

You will see many solar prices quoted "after subsidy". The PM Surya Ghar: Muft Bijli Yojana scheme provides central financial assistance for residential rooftop systems: ₹30,000 for a 1 kW system, ₹60,000 for 2 kW, and ₹78,000 for 3 kW and above (it is capped at the 3 kW level).

Two things matter here.

First, the subsidy is a reimbursement. You pay the full price, the system is installed, inspected and connected with a net meter, and then the subsidy is credited to your bank account. So you need the full amount up front, or a loan.

Second, the subsidy is paid only when a vendor registered with your DISCOM on the National Portal installs the system. Not every installer is registered. Origian Power is not a registered PM Surya Ghar vendor, so a system we install does not qualify for this subsidy. That is why we always quote the full price and never take a subsidy off our figures. If the subsidy is important to your decision, ask any installer whether they are registered with your DISCOM, and check the vendor list on the official portal yourself. Our PM Surya Ghar guide explains how the scheme works.

Payback: how to tell if it is worth it

Price on its own does not tell you whether solar is a good idea. What matters is how much you save each year compared with what you spend.

Here is a simple way to estimate it, using the same assumptions our calculators use: about 1,550 to 1,600 units per kW per year, and a flat ₹8 per unit for domestic electricity.

Take a 3 kW system:

• It produces roughly 4,650 to 4,800 units a year.
• At ₹8 a unit, that is worth roughly ₹37,000 to ₹38,000 a year in electricity you no longer buy.
• If the system costs ₹2.3 to ₹2.6 lakh, the simple payback is around six to seven years.

After payback, the system keeps producing for the rest of its life. Panels carry a 25-year performance warranty, and a well-installed system typically lasts 25 years or more.

This is a rough estimate, not a promise. Your real savings depend on how much of the solar power you use yourself, your actual tariff slab, shading, and how well the system is maintained. Our rooftop solar savings calculator lets you put in your own bill.

A few things can improve the numbers:

• Using power during the day. Running the washing machine, water pump or AC while the sun is out means you use your solar directly.
• Keeping the panels clean. Dust can noticeably reduce output, especially in dry months. See our solar panel cleaning guide.
• Sizing correctly. An oversized system exports more than you need, and an undersized one leaves savings on the table.

Commercial and larger systems

For businesses, the maths is often better, because commercial tariffs are higher. Our calculators assume ₹10 per unit for commercial connections. Businesses may also be able to claim depreciation on the system. We cover this in commercial rooftop solar in Telangana and Andhra Pradesh and in our solar depreciation calculator.

Our own installations include commercial hospital systems of 17 kW to 38 kW and a 55 kW commercial installation, so we see the commercial side regularly.

How to pay: cash, loan or EMI

Many families finance rooftop solar rather than paying cash. Banks and non-bank lenders offer solar loans, and when the monthly EMI is close to what you save on your bill, the system can effectively pay for itself from the first month. Our guide to solar loans in India explains the options, and our solar EMI calculator helps you compare.

Origian's team includes staff who handle bank and finance documentation, so we can help you through the loan paperwork if you choose that route.

Red flags in a solar quote

Watch out for these:

• A firm price without a site visit. Nobody can price your roof properly without seeing it.
• "After subsidy" prices with no conditions. The subsidy is never guaranteed and depends on the installer being registered.
• Brands without model numbers. Ask for the exact panel and inverter models.
• No mention of earthing or surge protection. These are safety items, not extras.
• No written warranty. You should get product, performance, inverter and workmanship terms in writing.
• Pressure to pay in full before installation. Stage payments are normal; full advance payment is a risk.

Questions to ask before you sign

1. What exact panel and inverter models will you install, and how many panels?
2. Is the structure galvanised, and what wind speed is it rated for?
3. Are earthing, a lightning arrestor and surge protection included?
4. Is the net metering application and DISCOM coordination included in the price?
5. What does maintenance include, how often, and how quickly do you respond to faults?
6. What are the warranties for panels, inverter and your workmanship, in writing?
7. If I want the PM Surya Ghar subsidy, are you a vendor registered with my DISCOM?

How Origian prices a system

When you contact us, the process is simple. We meet you and explain how the system works. We visit the site to check the roof, shading and your connection. Then we send a written quotation with the full price, the exact equipment and our warranty terms. Once you decide to go ahead, we collect the documents, handle the advance or loan processing, install the system, take care of the DISCOM documentation and approval, and switch it on. From confirmation to switch-on usually takes about 10 to 15 days.

We have been installing since 2020, with more than 300 installations and over 2,000 kW commissioned across Telangana and Andhra Pradesh. If you would like a price for your own roof, book a free site survey or look at our solar system prices first.

Frequently asked questions

How much does a 3 kW rooftop solar system cost in India? At Origian, a 3 kW on-grid rooftop solar system costs ₹2,30,000 to ₹2,60,000 before any subsidy. The range depends on the panel and inverter brands, roof type, structure height and cable runs. A site visit fixes the final price, and the quotation should list every component by make and model.

What is the price of a 1 kW solar panel system for home? Origian's gross price for a 1 kW rooftop solar system is ₹1,10,000 to ₹1,30,000. Per kW it costs more than larger systems, because the inverter, structure, protection, wiring and paperwork cost almost the same whatever the size. A 1 kW system suits homes using around 130 units a month.

How much does a 5 kW solar system cost in India? A 5 kW rooftop solar system from Origian costs ₹3,50,000 to ₹3,90,000 before any subsidy. In our region it produces about 650 units a month on average, which suits homes with several air conditioners or consumption of around 650 units a month. The exact price follows a site survey.

How much does a 10 kW rooftop solar system cost? Origian's gross price for a 10 kW rooftop solar system is ₹6,10,000 to ₹6,40,000. It produces about 15,500 to 16,000 units a year in our region, which suits large homes, villas and small businesses. Per kW it is cheaper than smaller systems, because fixed costs are spread over more panels.

Is the PM Surya Ghar subsidy deducted from the solar system price? No. PM Surya Ghar is a reimbursement: you pay the full price first, and the subsidy of up to ₹78,000 is credited to your bank account after installation, inspection and net metering. It is paid only for systems installed by a vendor registered with your DISCOM. Origian Power is not a registered PM Surya Ghar vendor.

How long does rooftop solar take to pay for itself in India? In our region a 3 kW rooftop solar system produces about 4,650 to 4,800 units a year, worth roughly ₹37,000 to ₹38,000 at ₹8 per unit. At a full price of ₹2,30,000 to ₹2,60,000, simple payback is around six to seven years, and the panels carry a 25-year performance warranty.

Do batteries increase the cost of a home solar system? Yes, significantly. A standard on-grid rooftop solar system needs no battery, because net metering banks your surplus with the grid. Adding batteries for backup means a hybrid inverter, the battery bank itself and its replacement every few years. Origian currently installs Luminous lead-acid batteries for hybrid systems.
