What is the Typical Solar System Cost in India?

The average cost of a solar system in India varies based on factors like panel type, system size, inverters, and installation challenges. Small residential solar setups usually start at around XXX, while larger commercial or industrial systems can go up to XXX. Other considerations, like energy storage integration, site conditions, and maintenance requirements, can also influence the overall cost.

At Energy Spoc, we guide you in selecting a solar panel system that offers the right balance of efficiency, reliability, and affordability. Our goal is to help you make a smart investment in clean, sustainable energy.

Solar Panel Cost With and Without a Subsidy

The cost of a solar panel system can vary depending on its size and whether government subsidies are applied. Here’s a general price range per kW (₹X – ₹Y per kW):

  • 1 kW system – ₹X – ₹Y
  • 3 kW system – ₹X – ₹Y
  • 5 kW system – ₹X – ₹Y

Subsidies lower initial expenses, making solar power more accessible for households and small businesses. The total price can vary based on the type of panels, inverter quality, and how complicated the installation is. At Energy Spoc, we help you choose a system that offers good performance, efficiency, and long-term savings.

Why Choose Rooftop Solar?

Top Reasons to Choose Solar Energy

The cost of a solar system in India ranges between ₹45,000 to ₹55,000 per kW (on-grid) and ₹75,000 to ₹95,000 per kW (off-grid with batteries). The price depends on system capacity, components, and site complexity.
In Mumbai, typical prices are:
  • 3 kW -- ₹1.6 -- ₹1.8 lakh
  • 5 kW -- ₹2.4 -- ₹2.6 lakh
  • 10 kW -- ₹4.5 -- ₹4.9 lakh
This includes installation, inverter, structure, and standard wiring.
Prices differ due to local installation costs, subsidy eligibility, roof type, and cable lengths. Urban locations like Mumbai may have higher logistics costs but better service accessibility.
Key cost factors include system size, type (on-grid, hybrid, off-grid), panel efficiency, inverter brand, structure material, and whether battery backup is included.
Yes. Solar systems have a payback period of 3–4 years, after which your electricity is nearly free for the remaining 20+ years of system life.
A 1 kW on-grid system costs around ₹45,000 – ₹55,000. It generates about 4 units/day, enough for small households.
A 3 kW system costs approximately ₹1.6 – ₹1.8 lakh and suits medium homes with monthly bills between ₹2,000–₹3,500.
A 5 kW setup costs ₹2.4 – ₹2.6 lakh and can offset up to ₹5,000–₹7,000 of your monthly electricity bill.
A 10 kW rooftop solar system costs ₹4.5 – ₹4.9 lakh. It's ideal for larger houses or small commercial establishments.
Yes. Under the PM Surya Ghar Muft Bijli Yojana, residential users can get up to ₹78,000 subsidy on rooftop systems up to 10 kW.
For commercial installations, cost per kW is lower — around ₹38,000 – ₹48,000 per kW, as bulk installations reduce unit pricing.
Industrial systems typically achieve ROI in 2.5–3 years due to higher daytime power consumption and electricity savings.
Yes. We provide end-to-end EPC (Engineering, Procurement, Construction) for industrial and corporate clients across Maharashtra and India.
Yes. Businesses can claim accelerated depreciation (40%), GST input credits, and CSR-linked sustainability credits.
  • CAPEX: You own the system and save fully on bills.
  • OPEX (RESCO): You pay per unit consumed while the EPC partner owns and maintains the system.
The government offers up to ₹78,000 subsidy through the National Rooftop Solar Portal for on-grid residential systems.
Currently, subsidies are available only for residential users. However, businesses benefit from depreciation and energy savings.
Yes. We manage complete subsidy documentation, portal registration, and DISCOM coordination at no extra cost.
Yes. We offer easy EMI plans and partner with banks/NBFCs to finance up to 80–90% of total project value.
Depending on system size and usage, savings range between ₹2,000 – ₹10,000 per month on electricity bills.
Follow this simple formula:
System Size (kW) × Cost per kW = Total Price
Example: 5 kW × ₹50,000 = ₹2.5 lakh approx.
You need 100 sq. ft per kW of shadow-free rooftop space for optimal installation.
Battery-based hybrid/off-grid systems cost ₹30,000–₹40,000 more per kW due to battery and inverter upgrades.
Mounting structures, cabling, inverter installation, and government inspection fees (if applicable).
Yes. Visit energyspoc.com/solar-cost-and-pricing or call +91 7710090940 for a free on-site cost assessment and ROI analysis.
Solar panels have a life span of 25–30 years, maintaining over 80% efficiency even after decades of use.
Basic cleaning and inspection cost around ₹2,000–₹3,000 per year for residential systems.
Every 10–15 days for optimal performance, especially in dusty or coastal regions like Mumbai.
  • Panels -- 25 years performance
  • Inverters -- 5–10 years
  • Structure -- 5 years
  • Installation -- 1 year
Yes. Inverters typically last 8–10 years and can be replaced easily without changing panels.
A 5 kW solar system offsets around 6 tonnes of CO₂ per year, equal to planting 300 trees.
