How much does a 1 kW solar system cost with subsidy?

Verde Solaire's published July 2025 range for 1 kW is ₹70,000 to ₹80,000. The central PM Surya Ghar subsidy on 1 kW is ₹30,000. In Noida, Greater Noida, Ghaziabad and Varanasi the Uttar Pradesh subsidy adds ₹15,000, so the net cost is ₹25,000 to ₹35,000. In Delhi the state adds ₹26,000, so the net cost is ₹14,000 to ₹24,000, plus ₹3 per unit generated for five years.

1 kW solar panel produces how many units?

On the published planning yield with a 10% derate for dust and monsoon, a 1 kW system in Noida generates about 1,350 units a year, or about 113 units a month. In Delhi it is about 1,305 units a year, or about 109 units a month. Summer months give more and the monsoon and winter give less.

How many units does a 1 kW solar panel produce per day?

About 3.6 to 3.7 units a day averaged across the year in Delhi NCR (1,305 to 1,350 units a year). A clear May day gives more than that and a foggy January day gives less; size the system on the yearly average, not on the best day.

What is the 1 kW solar panel price in Delhi?

₹70,000 to ₹80,000 on Verde Solaire's published July 2025 list. After the ₹30,000 central subsidy and the ₹26,000 Delhi state subsidy the net cost is ₹14,000 to ₹24,000. Delhi also pays a generation-based incentive of ₹3 per unit for five years, about ₹3,915 a year on 1,305 units.

What is the 1 kW solar panel price in Noida?

₹70,000 to ₹80,000 published, and ₹25,000 to ₹35,000 after the ₹30,000 central subsidy and the ₹15,000 Uttar Pradesh subsidy. Net metering in Noida city is through PVVNL; Greater Noida and Greater Noida West are on NPCL.

How many solar panels are needed for 1 kW?

Two panels of about 540 Wp, the module size on Verde Solaire's recent installations. They need roughly 100 to 117 square feet of shadow-free roof, a third of the published 300 to 350 square feet for 3 kW.

Is a 1 kW solar system enough for a home?

It suits a home using about 100 to 150 units a month with no air conditioner in regular use. The PM Surya Ghar sizing guide puts 0 to 150 units at 1 to 2 kW and 150 to 300 units at 2 to 3 kW. Because the central subsidy is ₹30,000 per kW for the first 2 kW, most homes in Delhi NCR are quoted 2 or 3 kW rather than 1 kW.

Name: 1 kW solar system price with subsidy
Brand: Verde Solaire
SKU: rooftop-solar-1kw
Availability: InStock

A 1 kW system is for a compact home with fans, lights, a fridge and a television, rather than regular air-conditioner use.

The published price is ₹70,000 to ₹80,000 before subsidy. After the central subsidy and state top-up, the estimated amount is ₹25,000 to ₹35,000 in Noida and ₹14,000 to ₹24,000 in Delhi. It produces about about 113 units a month in Noida or about 109 units a month in Delhi.

Use this as a starting point for your decision. The sections below explain output, subsidy and why a slightly larger system often delivers better value. Your written quote follows a roof survey.

Indicative prices. Your written quote, after a free site survey, is the final price. Delhi systems up to 3 kW also earn ₹3 per unit generated for five years (₹2 per unit for 3–10 kW). The UP state top-up is paid on top of the central subsidy; we confirm the current amount in your quote.

The published range includes panels, inverter, mounting structure, net metering, installation and warranty. Verde Solaire's published residential range starts at this size: home systems from 1 kW to 50 kW.

What a 1 kW system is: panels, size and roof area

A 1 kW system is two panels. Verde Solaire's recent installations used modules of 530 to 545 Wp, so two 540 Wp panels make a shade over 1 kW. On a raised metal structure they take about 100 to 117 square feet of shadow-free roof, a third of the published 300 to 350 square feet for 3 kW. Almost any independent house, and most builder floors with roof rights, has that much space.

The rest of the system, an on-grid inverter, cabling, earthing, distribution boxes and the bidirectional meter, is the same as on a larger installation, which is why the price per kW is higher at 1 kW than at 3 kW.

How many units a 1 kW system generates

The planning figure on Verde Solaire's published savings pages is 1,500 units per kW per year in Noida and 1,450 in Delhi. With a 10% derate for dust, heat and the monsoon, that gives about 113 units a month in Noida and about 109 units a month in Delhi, or between 3.5 and 4 units a day averaged over the year.

The average hides the seasons: a clear day in May produces well above it, a foggy week in January well below it. Net metering carries credit from month to month, so the yearly total is what matters. Shading, and panels facing east or west rather than south, reduce the figure on a real roof; a survey catches both. The monsoon and dust page has the seasonal picture.

The subsidy on 1 kW

The central subsidy under PM Surya Ghar: Muft Bijli Yojana is ₹30,000 per kW for the first 2 kW, then ₹18,000 for the third, capped at ₹78,000 for 3 kW and above. On 1 kW that is ₹30,000, the same anywhere in India.

The state top-up differs. Uttar Pradesh adds ₹15,000 per kW, capped at ₹30,000 per consumer, on top of the central subsidy, so a 1 kW system in Noida, Greater Noida, Ghaziabad or Varanasi receives ₹45,000 in total. Delhi adds ₹26,000 per kW, capped at ₹78,000 (3 kW), so the same system in Delhi receives ₹56,000 in total, plus a generation-based incentive (GBI) of ₹3 per unit for homes up to 3 kW, falling to ₹2 per unit above 3 kW, paid for 5 years from commissioning, paid monthly against the bill; any excess to the bank account. On the Delhi generation figure that is ₹3,915 a year, or ₹19,575 over five years, on top of a net price already below Uttar Pradesh's at this size.

Both state subsidies sit on top of the central one. The scheme's official end date is 31 March 2027. The subsidy is credited to your bank account after commissioning, not deducted from the quote; the subsidy guide explains who pays whom and when.

Why most homes outgrow 1 kW

The subsidy formula rewards the second kW as much as the first. Both are subsidised at ₹30,000 per kW, and Uttar Pradesh's top-up reaches its cap at exactly 2 kW. So a 2 kW system in Noida nets to ₹45,000 to ₹60,000 against ₹25,000 to ₹35,000 for 1 kW: the second kilowatt costs less than the first. In Delhi the comparison is ₹23,000 to ₹38,000 against ₹14,000 to ₹24,000. Per kW, 2 kW is the cheapest size after subsidy in both states.

Consumption also grows, and adding panels later means a second application, a second inspection and possibly a larger inverter. Whether a household that took the subsidy on 1 kW can later claim the balance on an expansion is not addressed in the published rules, so size the first application to the consumption you expect in three years. The published sizing guide is 0–150 units a month: 1–2 kW · 150–300 units: 2–3 kW · above 300 units: above 3 kW.

Who 1 kW suits, and who should size up

1 kW is the right size when three things are true.

Your average is about 100 to 150 units a month across the whole year. Add up twelve bills and divide by twelve; summer bills alone overstate it.
You do not run an air conditioner through the summer. One in regular use through May and June usually takes a home out of this band.
The roof or the sanctioned load limits you. A small terrace with a water tank in the middle, or a sanctioned load of 1 kW, can make 1 kW the practical maximum.

Size up when the average is above 150 units, when an air conditioner or an electric vehicle is on the way, or when the roof has room for three panels more. The 3 kW page covers the size most Delhi NCR homes are quoted, and the 3 kW versus 5 kW guide the step after that.

What happens to the bill

In Uttar Pradesh a 1 kW system generating about 113 units a month removes almost the whole energy charge for a home using about that much. The fixed charge on the sanctioned load remains, because solar does not remove it. On the published slab rates the net cost in Noida is recovered in roughly three and a half to five years; the bill calculator shows the arithmetic for your own units and sanctioned load.

Delhi is different. Delhi's free-power subsidy gives 0–200 units a month free; 201–400 units at 50% off, capped at ₹800 a month; you must opt in. A home using about 110 units a month that has opted in already pays no energy charge, so a 1 kW system saves little on the bill itself. Its return is the GBI, ₹3,915 a year for five years, and staying under the 200-unit line as consumption grows, because worked out on net units, that is import minus export.

Delhi's Cabinet has also approved a scheme offering up to 3 kW at zero upfront cost, "subject to technical feasibility" to households below a consumption threshold that every home in the 1 kW band is well inside. If it is notified as reported, a self-funded 1 kW system in Delhi would be hard to justify; the zero-upfront scheme page tracks what is approved against what is notified.

Paying for it

At this size most customers pay cash, because the net figure is small. The alternative is the PM Surya Ghar concessional loan: collateral-free, from nationalised banks, at repo rate plus 0.5 percentage points, which was 5.75% on 28 July 2026, over 10 years. On a 1 kW net figure the EMI is a few hundred rupees a month. Verde Solaire has tie-ups with SIDBI, SBI and other NBFCs for collateral-free solar loans and prepares the paperwork with you; the EMI calculator takes any principal, rate and tenure.

Net metering for a 1 kW system

The paperwork is the same as for 3 kW, and Verde Solaire files it as a registered PM Surya Ghar vendor in both Delhi and Uttar Pradesh. In Delhi the DERC guidelines give the electricity board 10 days to connect a system up to 10 kW, with no application fee for domestic consumers; see the Delhi net-metering page. In Uttar Pradesh, under the UPERC rooftop solar regulations of 2019, residential users may choose net or gross metering, and the DISCOM allows capacity within transformer limits; the Noida net-metering page walks through PVVNL's process.

Verde Solaire has published a 2 kW installation in Varanasi under PM Surya Ghar, with Adani 540 Wp modules and a KSolare inverter. Rakhi Sharma, whose 2 kW system was installed under the subsidy scheme, wrote: "The staff of Verde Solaire was very cooperative and helpful. Their installation was top class and was as per their promise."

Equipment and compliance at 1 kW

The rules do not relax for a small system. Subsidised installations must use panels where both the modules and the cells must be made in India, and from 1 June 2026 the cells must appear on the ALMM List-II as well as the modules. GST on a rooftop solar plant is about 8.9%: 5% on the panels and inverter (70% of the contract value) and 18% on the rest of the material and installation (30%). The panels in Verde Solaire's July 2025 price posts carried 25-year performance warranties on all three panel types. A 1 kW quote should still name the panel make, model and wattage, the inverter make and rating, and who pays the meter charges. What ALMM List-II means for your subsidy, and how to read a datasheet, are on the solar panels page.

1 kW prices by city

The system and the central subsidy are the same in every city. The state subsidy, the electricity board and the tariff differ, which is why each city has its own page: Delhi, Noida, Greater Noida, Ghaziabad and Varanasi.

The neighbouring sizes are the 2 kW page, the 3 kW page and the 5 kW page. The calculator below gives savings, payback and EMI in one place.
