Electricity bills going up every year. Power cuts during summers. Sound familiar? A 1kW solar system is the most affordable step a homeowner can take to fight back and with the government's PM Surya Ghar Muft Bijli Yojana offering a flat ₹30,000 subsidy, there's no better time to go solar.
This guide covers everything you need to know: the latest 1kW solar panel price in India, system types, specifications, installation costs, subsidy process, and real savings all updated for 2026.
What Is a Home Solar System? A Quick Overview
A home solar system converts sunlight into electricity using solar panels. That electricity is used to power your appliances: fans, lights, TV, refrigerator — and any excess can either be stored in batteries or fed back to the grid.
Key components of a home solar system:
Solar Panels: Absorb sunlight and generate DC (direct current) electricity
Solar Inverter: Converts DC to AC (alternating current) electricity for home use
Mounting Structure: Holds the panels at the right angle on your roof
Solar Battery (optional): Stores excess energy for use during the night or cloudy days
Balance of System (BoS): Cables, fuses, MCBs, distribution boxes, and monitoring units
A 1kW solar system is the entry-level option: small, efficient, and perfect for homes with a monthly electricity consumption of under 100–150 units.
How a 1kW Solar System Works — and Why It's Right for You
Here's the simple version of how it works:
Sunlight hits the panels → DC electricity is generated
DC passes through the inverter → converted to AC electricity
AC electricity powers your home → solar energy is the first priority
Excess electricity → stored in battery (off-grid/hybrid) or exported to grid (on-grid)
At night or low sunlight → battery backup or grid power takes over
Benefits of a 1kW Solar System
Saves ₹600–₹1,200/month on electricity bills
Generates 4–5 units of electricity per day (about 120–150 units/month)
Requires only ~80–100 sq. ft. of roof space — ideal for small homes
Low maintenance — just occasional cleaning
25-year panel lifespan with manufacturer warranty
Reduces carbon footprint by ~1.2–1.5 tonnes of CO₂ per year
Eligible for ₹30,000 government subsidy under PM Surya Ghar Yojana
Payback period: 3.5–5 years depending on system type and usage

Types of 1kW Home Solar Systems
There are three main types of 1kW solar systems available in India. Each suits a different kind of household and electricity situation. Let's break them down:
1kW Off-Grid Solar System
An off-grid system runs independently from the electricity grid. Solar panels charge a battery bank during the day, and that stored energy powers your home at night or during outages.
1kW Off-Grid Solar System Specifications
Component | Specification |
Solar Panel Capacity | 1000 Wp (e.g., 4 × 250W or 2 × 500W Mono PERC panels) |
Solar Inverter | 1 kVA / 12V or 24V PWM or MPPT inverter |
Battery Bank | 12V × 2 batteries (150Ah) or 24V × 1 battery (150Ah) |
Backup Time | 6–8 hours (basic load) |
Charge Controller | PWM or MPPT (30A–50A) |
Approximate Price | ₹55,000 – ₹80,000 |
Subsidy Applicable | No (off-grid systems do not qualify) |
Best For | Rural areas, frequent power cuts, no grid availability |
Appliances you can run: 4–5 LED lights, 2 ceiling fans, 1 TV, 1 refrigerator (small), mobile chargers.
1kW Hybrid Solar System
A hybrid system connects to both the electricity grid and a battery bank. During the day, solar power runs your home. Excess power charges the battery. If the battery is full, surplus electricity is exported to the grid. At night or during a power cut, the battery kicks in.
1kW Hybrid Solar System Specifications
Component | Specification |
Solar Panel Capacity | 1000 Wp (Mono PERC or Bifacial panels) |
Solar Inverter | 1 kVA Hybrid Inverter (with MPPT charge controller built-in) |
Battery Bank | 1 × 150Ah Lithium or Lead-Acid Battery |
Grid Connection | Yes — Net Metering applicable |
Backup Time | 4–6 hours (basic load) |
Approximate Price | ₹85,000 – ₹1,20,000 |
Subsidy Applicable | Yes — ₹30,000 under PM Surya Ghar Yojana |
Best For | Homes that need backup AND want to save on bills |
1kW On-Grid Solar System
An on-grid (or grid-tied) system is connected directly to the electricity grid. When solar generates more power than you use, it's exported to the grid, and you earn credits under the Net Metering policy. There's no battery — so no backup during a power cut.
1kW On-Grid Solar System Specifications
Component | Specification |
Solar Panel Capacity | 1000 Wp (Mono PERC or Bifacial panels) |
Solar Inverter | 1 kW Grid-Tied String Inverter |
Battery Bank | None |
Grid Connection | Yes — with Net Metering |
Approximate Price | ₹55,000 – ₹75,000 |
Subsidy Applicable | Yes — ₹30,000 under PM Surya Ghar Yojana |
Net Price After Subsidy | ₹25,000 – ₹45,000 |
Best For | Urban homes with stable electricity supply |
Pro tip: If your area has a stable grid and power cuts are rare, an on-grid system gives you the fastest payback period and the biggest bill savings

Solar Inverter (1 kVA) | ₹8,000 – ₹15,000 |
Mounting / Racking Structure | ₹4,000 – ₹7,000 |
DC/AC Wiring & Cables | ₹2,500 – ₹4,000 |
Junction Box, MCB, Earthing | ₹1,500 – ₹3,000 |
Net Metering Application (on-grid) | ₹2,000 – ₹5,000 |
Labour & Installation Charges | ₹5,000 – ₹10,000 |
Battery (off-grid/hybrid only) | ₹12,000 – ₹25,000 |

Total (Off-Grid, With Battery) | ₹55,000 – ₹80,000 |
Total (Hybrid, With Battery) | ₹85,000 – ₹1,20,000 |
State-wise price variation: Prices in metros like Delhi, Mumbai, and Kolkata may be 5–10% higher due to logistical costs. States like Gujarat, Rajasthan, and Maharashtra often have lower prices due to high solar installer density.
1kW Solar Panel Price in Kolkata: For an on-grid 1kW system in Kolkata, expect to pay ₹60,000–₹80,000 before subsidy, with installation charges slightly higher due to humidity and structural requirements.
1kW Solar System Subsidy in India (PM Surya Ghar Yojana 2026)

Frequently Asked Questions (FAQs)
How many units does a 1kW solar panel produce per day?
1kW solar system generates 4–5 units (kWh) of electricity per day on average, assuming 4–5 peak sun hours. This comes to about 120–150 units per month and roughly 1,440 units per year.
What is the area required for a 1kW solar panel installation?
You need approximately 80–100 sq. ft. of shadow-free, open rooftop space for a 1kW solar system. The panels must receive direct sunlight without shade from trees, overhead water tanks, or adjacent buildings.
What appliances can a 1kW solar system run?
1kW system can comfortably power the following simultaneously (up to ~800W load):
4–5 LED lights (5–9W each)
2 ceiling fans (70–80W each)
1 LED TV (50–100W)
1 small refrigerator (100–150W)
Mobile chargers and other small electronics
Note: Air conditioners (1.5 ton = ~1500W) are too heavy for a 1kW system to run continuously.
Is a 1kW solar system eligible for government subsidy?
Yes — a 1kW on-grid or hybrid solar system qualifies for a ₹30,000 subsidy under the PM Surya Ghar Muft Bijli Yojana. Off-grid systems are not eligible for central government subsidy. Some states offer additional top-up subsidies.
What is the payback period for a 1kW solar system?
For a 1kW on-grid system after subsidy (net cost ~₹25,000–₹45,000) with monthly savings of ₹700–₹1,000, the typical payback period is 3–4.5 years. After that, you enjoy free electricity for the remaining 20+ years of the system's life.
Which is better — on-grid, off-grid, or hybrid for a 1kW system?
It depends on your situation:
On-Grid: Best if your area has a stable power supply and you want the lowest cost with subsidy
Off-Grid: Best if you face frequent long power cuts or live in an area without a reliable grid
Hybrid: Best if you want both bill savings AND backup power — at a higher upfront cost
How do I check if my 1kW solar installer is MNRE-approved?
Visit the National Portal for Rooftop Solar at pmsuryaghar.gov.in or your state DISCOM's website. They maintain an updated list of empanelled vendors. Buying from an MNRE-approved installer is mandatory to be eligible for the PM Surya Ghar subsidy.
🌞 Ready to Go Solar? A 1kW solar system is one of the smartest financial decisions a homeowner can make in India today. With the PM Surya Ghar subsidy reducing your cost by ₹30,000, and electricity savings starting from day one, the numbers simply make sense. Always buy from an MNRE-empanelled installer, compare at least 3 quotes, and opt for Mono PERC or Bifacial panels for the best long-term performance. |
