Quick Answer: A home solar system can cost around ₹45,000–₹70,000 for 1 kW, while larger systems cost more depending on their capacity and installation requirements. These prices are indicative. Your total cost depends on the panels, inverter, mounting structure, wiring, installation, and applicable net metering requirements. Eligible households may also reduce their upfront cost through the PM Surya Ghar scheme.
If you're planning to install solar at home, start with two things: how much electricity your household uses and how much roof space you have. These will help you work out what system size you need and what it might cost.
How Much Do Household Solar Panels Cost?
The cost of a home solar system depends on its size, the equipment you choose, your roof condition, and the work required for installation. The price of the panels alone won't tell you what the complete system will cost.
What a full solar quote should include:
- Solar panels (the generation component)
- Inverter (converts DC to usable AC power)
- Mounting structure (rooftop or ground frame)
- Wiring, junction boxes, and earthing
- Net metering application and approval fees
- Installation labor and commissioning
Roof reinforcement, battery storage, and ongoing operations and maintenance (O&M) may cost extra, depending on the project and the quote. Check what's included before comparing prices between installers.
Solar Power System Cost by kW
Solar power system cost scales with kilowatt (kW) capacity, but the relationship is not purely linear since fixed costs like net metering and labor get spread across larger systems.
| System Size | Typical Home Fit | Indicative Cost System |
|---|---|---|
| 1 kW | Basic household electricity needs | ₹45,000–₹70,000 |
| 3 kW | A household with moderate electricity use | ₹1.5–₹2 lakh |
| 5 kW | A home with higher electricity consumption | ₹2.25–₹3.25 lakh |
| 10 kW | A high-consumption home or farmhouse | ₹4.5–₹6.5 lakh |
The right system size depends on your electricity consumption, the appliances you use, available roof space, and whether you want to offset daytime usage or a larger share of your overall consumption. A site assessment can help determine the capacity that fits your home.
What Is Cost of Solar Panels at Each Size
The panel cost at each size depends on wattage per panel, the number of panels needed to hit your target kW, and the panel technology chosen. A 3kW system and a 5kW system use the same component categories, panels, inverter, structure, but differ in quantity and inverter rating. The prices above are indicative estimates for planning. The total cost of a complete installation can vary based on the equipment and site requirements.
Cost for a Solar Power System: What's Included
A complete solar power system cost covers five core components working together, not a single line item. Understanding each one helps you compare quotes accurately instead of chasing the lowest headline number.
- Panels: generate DC electricity from sunlight
- Inverter: converts DC to grid-compatible AC
- Mounting structure: holds panels securely on roof or ground
- Wiring and protection: connects components safely and meets electrical code
- Net metering setup: enables export of surplus power to the grid
Solar System Costing. Line-by-Line
A solar installation quote brings together the cost of equipment, mounting, electrical work, labour, and any applicable approval or connection charges.
Expert Advice: Ask for an itemized quote instead of comparing only the final amount. It helps you understand which components are included and whether important work has been left out.

Cost for a Solar System After Government Subsidy
Government assistance can reduce the upfront cost of an eligible residential rooftop solar system. The main scheme for households is PM Surya Ghar Muft Bijli Yojana. PM-KUSUM, meanwhile, covers specified agricultural solar applications rather than being a general subsidy for household rooftop systems.
Under PM Surya Ghar, the central subsidy for eligible households in Gujarat is:
| System Capacity | Central Subsidy |
|---|---|
| 1 kW | ₹30,000 |
| 2 kW | ₹60,000 |
| 3 kW or more | upto ₹78000 |
When estimating your budget, look at the system's price before subsidy and the assistance you may qualify for separately. This gives you a clearer picture of the upfront amount and the potential cost after subsidy.
Net metering requirements and approval steps depend on the applicable scheme and electricity distribution company. Check the requirements for your connection as part of the installation process.
Red Flag: Be cautious of any installer who promises a subsidy amount without reviewing your specific location, connection type, and application eligibility first. Subsidy figures are scheme-dependent, not fixed per installer.
Solar Energy Panel Cost vs Total System Cost
Solar energy panel cost alone misleads buyers because panels are just one of five major cost components in a working system. A low per-panel price can hide a weak inverter, thin wiring, or a mounting structure that won't hold up through monsoon seasons.
Running-cost savings matter more over the system's lifetime than the initial sticker price. A well-installed system reduces your grid electricity draw for years, and the savings compound as electricity tariffs rise over time. According to the U.S. Department of Energy's solar energy cost and data analysis, system performance and long-term output, not just upfront price, determine real value.
Buying tip: When comparing quotes, look beyond the price per watt. Check the equipment included, the expected generation, warranty terms, and installation scope.
Final Solar System Cost: Factors That Change Your Number
Your final solar system cost shifts based on roof type, location, household load profile, and brand choice for panels and inverters. A sloped tile roof needs different mounting hardware than a flat concrete roof, which changes labor and structure costs.
Key factors that move your number:
- Roof type and condition: flat RCC roofs are generally simpler to mount than tiled or metal roofs
- Location: shading, orientation, and local weather affect system sizing
- Load profile: AC units, water heaters, and motors push you toward a larger kW system
- Brand choice: panel and inverter brand affect both price and expected lifespan
For households and farms in Gujarat, service area coverage affects installation timelines and site survey scheduling. Raycal Power's EPC work spans industrial and ground-mounted projects across Amreli, Bhavnagar, Banaskantha, Surat, and Kalawad, and
Likewise is worth clarifying upfront so you know exactly what service you're requesting.
Is Solar Worth It for Your Home?
Solar is generally worth it for homes with consistent daytime electricity use, adequate roof space, and access to net metering, since the combination of subsidy support and reduced grid bills improves payback over time. The decision depends on your specific load profile, roof condition, and local subsidy eligibility rather than a single national average.
If you run high-consumption appliances like air conditioners through the day, a correctly sized system can offset a meaningful share of your bill. If your usage is light and intermittent, a smaller system may make more financial sense than over-building capacity you won't use.
Raycal Power works across Gujarat on ground-mounted solar EPC, industrial rooftop solar, government scheme navigation including PM Surya Ghar and KUSUM, net metering approvals, O&M contracts, and SCADA monitoring for industrial and institutional clients.
