July 2026 update

1 kW turnkey ₹65–95k; CFA ₹30k; net ₹35–65k.

In July 2026, cross-check these figures against your bill; ranges assume daytime self-use and a typical residential tariff.

Editor’s take — James Holloway

1 kW is the subsidy graduate tier — the smallest plant that opens the ₹30k DBT door. If you only have a balcony rail, skip it and stay at 500 W. If you have 120 sq ft of roof and 150 units on the bill, this is your entry ticket.

Frequently Asked Questions

How much subsidy do I get for a 1kW solar system under PM Surya Ghar Yojana?

For a 1kW system, you are eligible for a flat subsidy of ₹30,000 directly into your bank account. This scheme applies only to on-grid residential installations that are connected with net metering.

What is the total cost of a 1kW solar system with subsidy in India?

After deducting the ₹30,000 government subsidy, the net cost for a consumer usually ranges between ₹45,000 and ₹55,000. The upfront cost before subsidy is typically ₹75,000 to ₹85,000 depending on the brand and state.

How much roof space is required for a 1kW solar plant?

A 1kW solar system generally requires approximately 80 to 100 square feet of shadow-free rooftop area. This space is needed to mount 2 to 3 high-efficiency solar panels.

How many units of electricity does a 1kW system generate daily?

In Indian weather conditions, a 1kW solar system generates approximately 4 to 5 units (kWh) of electricity per day on average, amounting to roughly 120–150 units per month.

What is the Return on Investment (ROI) period for a 1kW solar system?

With the current subsidy and electricity rates, the payback period is typically 3 to 4 years. After this period, the electricity generated is essentially free for the remaining lifespan of the panels.

Can I install a 1kW solar system if I live in an apartment?

Yes, but you need exclusive roof access or permission (NOC) from your society to install panels on the common terrace. Alternatively, some states allow 'virtual net metering' or group housing connections.

Which are the best solar panel brands in India for residential use?

Top reliable brands in 2026 include Tata Power Solar, Adani Solar, Waaree Energies, Vikram Solar, and Goldi Solar. These companies offer high-efficiency modules and robust warranty support.

Is Net Metering mandatory for claiming the subsidy?

Yes, installing a bi-directional net meter is mandatory to avail of the PM Surya Ghar subsidy. Net metering allows you to export excess power to the grid and get credit on your electricity bill.

How much does an off-grid 1kW solar system with batteries cost?

An off-grid 1kW system is significantly more expensive due to battery costs, ranging from ₹80,000 to ₹1,25,000. Note that off-grid systems are generally not eligible for the PM Surya Ghar central subsidy.

Will I still get an electricity bill after installing solar?

You will receive a bill for fixed charges (meter rent, etc.) and any electricity consumed over and above your solar generation. If you generate more than you consume, your bill for energy usage will be zero.

What maintenance do solar panels require?

Solar panels are low maintenance, requiring only bi-weekly cleaning with water to remove dust and bird droppings. Regular cleaning ensures optimal efficiency and generation.

1kw solar panel price India 2026 India.

In 2026, the average price for a 1kW on-grid solar system in India is ₹72,000 to ₹82,000 before subsidy. With the ₹30,000 PM Surya Ghar subsidy, the final cost to the consumer is approximately ₹42,000 to ₹52,000.

How much will solar panels cost in 2026?

Residential solar costs have stabilized, with 1kW systems averaging ₹75,000 (pre-subsidy) and 3kW systems around ₹1.8 Lakhs. High-efficiency bifacial or TOPCon panels may command a slight premium of 10-15%.

What is the price of solar panels in May 2026?

Prices in May 2026 remain stable following the start of the financial year, with 1kW mono-perc modules costing roughly ₹22-₹26 per watt individually. Complete system prices hover around the ₹50,000 mark post-subsidy.

What is the solar market in India 2026?

The Indian solar market in 2026 is booming with over 122 GW of installed capacity, driven by the massive adoption of the PM Surya Ghar scheme. The market is shifting towards higher efficiency technologies like TOPCon and domestic manufacturing.

How good are solar panels in 2026?

Solar panels in 2026 are highly efficient and durable, with commercial modules offering 22-25% efficiency. They are robust enough to withstand extreme Indian weather and come with performance warranties of up to 30 years.

What is the budget for solar in 2026?

For a standard home, you should budget between ₹50,000 (for 1kW) to ₹1.5 Lakhs (for 3kW) after factoring in subsidies. It is advisable to keep an additional ₹5,000–₹10,000 for structure strengthening or higher cabling requirements.

Can I run a 1.5 ton AC on solar?

You cannot run a 1.5-ton AC on a 1kW system alone, as the AC consumes 1.5kW–2kW of power and requires 8–12 units daily. You would need at least a 3kW solar system to effectively power a 1.5-ton AC along with other household loads.

Will solar panels ever reach 50% efficiency?

Commercial rooftop panels will not reach 50% efficiency in 2026; they currently average 22–25%. While 50% efficiency is theoretically possible with multi-junction cells in labs, it is not yet commercially viable for residential use.

How long do solar panels last in 2026?

Modern solar panels have a useful lifespan of 25 to 30 years. Most Tier-1 manufacturers in 2026 offer performance warranties guaranteeing that panels will still produce 80-85% of their rated power after 25 years.

What is the new solar panel technology for 2026?

The dominant new technologies in 2026 are TOPCon (Tunnel Oxide Passivated Contact) and HJT (Heterojunction) panels, which offer better efficiency than older Mono-PERC models. Bifacial panels, which generate power from both sides, are also becoming standard for rooftops.
