In 2026, Indian homes are taking the first step toward going solar with a 1 kW solar system. The 1 kW Solar Panel Price ranges from 50,000 and Rs. 70,000 per day in terms of electricity produced prior to the PM Surya Ghar subsidy. With the subsidy of Rs. 30,000 per kW for systems up to 2 kW, the effective cost comes down to Rs. 20,000 Rs. 40,000 for a basic on-grid installation. This guide provides the answers to these three questions that every home buyer asks: What is the 1 kilowatt solar panel price, how many 1 kW solar panels are required to produce a 1 kW solar PV system, and what is the subsidy available for a 1kw solar power system?
A 1 kW Solar system is not capable of supplying the same energy in every location and season. The answer to the question, 1 kw solar generates how many units, dependent on peak sun hours, roof orientation, roof tilt angle, solar panel technology, inverter efficiency and shading from surrounding structures.
Across India, average daily output for a well-installed 1 kW solar system falls in the following ranges:
Period | Average Output (India) | Peak Output (Rajasthan/Gujarat) | Lower Output (Coastal/Monsoon) |
Per day | 4 to 5 units | 5 to 6 units | 3 to 4 units |
Per month | 120 to 150 units | 150 to 180 units | 90 to 120 units |
Per year | 1,400 to 1,600 units | 1,600 to 1,800 units | 1,100 to 1,400 units |
For most Indian locations the honest answer for 1 kW solar panel unit generation per day is 4 to 5 units under average conditions, with meaningful variation by state and season.
For a deeper dive into how panel technology affects 1 kW solar power output per day, our types of solar panels guide covers Mono PERC, TOPCon, HJT, and bifacial options in detail.
The 1 kilowatt solar panel price in India in 2026 varies depending on the system configuration, the panel brand and technology, and the inverter type your installer specifies.
Configuration | Price Range (Before Subsidy) | Notes |
Basic on-grid 1 kW | Rs. 50,000 to Rs. 60,000 | Grid-tied only, no battery, most common for PM Surya Ghar applicants |
1 kW with battery | Rs. 80,000 to Rs. 1,10,000 | Includes backup power for outages |
1 kW hybrid system | Rs. 90,000 to Rs. 1,20,000 | Battery plus grid export capability |

The PM Surya Ghar Muft Bijli Yojana, launched by the Government of India, is the central scheme for residential rooftop solar adoption. The subsidy structure for 2026 is:
From June 1, 2026, all new residential installations must use ALMM-compliant panels manufactured with ALMM List-II certified domestic cells. Using a non-compliant panel brand risks outright subsidy rejection after installation. Verify your panel’s compliance before work begins. (source)
Roof space required: A standard 1 kW system uses 3 to 4 solar panels of 330 Wp to 400 Wp each. Each panel measures roughly 1.7m x 1.0m, so the total footprint is 80 to 100 square feet of usable, unshaded rooftop.
Installation time: For a residential rooftop on an accessible RCC slab, installation is typically completed in 1 to 2 working days.
What is in a 1 kW solar panel kit:
1 kW solar panel installation cost: Installation labour is typically Rs. 8,000 to Rs. 15,000 and is usually included in the total system quotation. Always confirm this with your installer.
Our comprehensive solar panel installation guide covers the end-to-end process, from site assessment to net metering activation.
What a 1 kW system powers comfortably:
What it cannot power adequately:
A 1 kW solar system for home is best suited for 1 BHK to small 2 BHK households with a monthly grid bill of Rs. 800 to Rs. 1,500. If your monthly bill is consistently above Rs. 2,000, a 2 kW or 3 kW system is likely a better fit.
For households with higher consumption, our solar panel calculator guide helps size the right system based on actual load data.
The 1 kW solar panel with battery price is significantly higher than a basic on-grid system, but the use case is valid for buyers in areas with frequent grid outages.
Why add a battery to a 1 kW system:
Battery sizing for a 1 kW system:
A quality lithium battery adds Rs. 25,000 to Rs. 50,000 to the system cost. Note that battery-based systems do not typically qualify for the PM Surya Ghar subsidy in the same way on-grid systems do. Confirm eligibility before choosing a hybrid or off-grid configuration.
A 1 kW solar system in India in 2026 delivers a compelling combination of low entry cost, meaningful electricity generation, and a Rs. 30,000 PM Surya Ghar subsidy that makes the effective investment genuinely accessible for most households. The 1 kW solar panel price in India, post-subsidy, of Rs. 20,000 to Rs. 30,000 is among the most cost-effective energy investments available to a small household today.
Verify ALMM List-I compliance for the panel model your installer proposes, confirm List-II cell sourcing from June 2026, and size your system honestly against your actual consumption. GSE Renewables provides end-to-end rooftop solar installations using fully ALMM-compliant panels.

A 1 kW solar panel system generates 4 to 5 units of electricity per day on average across most Indian locations. In high-irradiance states like Rajasthan and Gujarat, daily output can reach 5 to 6 units. In coastal areas or during monsoon months, expect 3 to 4 units per day. Annual generation typically ranges from 1,400 to 1,600 units under average conditions.
The 1kw solar panel price in india in 2026 ranges from Rs. 50,000 to Rs. 60,000 for a basic on-grid system before any subsidy. Adding a battery backup configuration brings the total to Rs. 80,000 to Rs. 1,10,000. These prices include panels, inverter, mounting structure, wiring, and installation.
Under the PM Surya Ghar Muft Bijli Yojana, a 1 kW residential on-grid rooftop solar system qualifies for a subsidy of Rs. 30,000. The net out-of-pocket cost post-subsidy comes to approximately Rs. 20,000 to Rs. 30,000 for a basic on-grid configuration.
A 1 kW solar system requires 80 to 100 square feet of usable, unshaded rooftop area. This accommodates 3 to 4 panels of 330 Wp to 400 Wp each.
The 1 kW solar panel installation cost — meaning labour and mounting hardware — typically runs Rs. 8,000 to Rs. 15,000 and is usually included in the total system quotation. Installation on a standard RCC slab rooftop takes 1 to 2 working days.
No. A standard 1-ton air conditioner draws 800 W to 1,200 W under load, which would consume the entire output of a 1 kW solar system. If running an AC is a priority, a minimum 3 kW to 5 kW system is recommended.
A 1 kW solar system without a battery (on-grid) exports surplus power to the grid and draws from the grid when solar generation is insufficient. It cannot provide power during grid outages. Adding a battery creates backup capability and allows evening use of stored solar power, but increases cost by Rs. 25,000 to Rs. 50,000 and may affect subsidy eligibility.
