Why Go Solar
The Smartest Investment a Business or Home Can Make
Electricity is one of the largest recurring costs for Indian industries, institutions and households, and grid tariffs only climb year after year. A well-engineered solar power plant turns that liability into a 25-year asset: it slashes your monthly bills from day one, protects you from tariff hikes, and typically pays for itself in just 3 to 5 years. Everything after that is effectively free, clean power.
With falling module prices, accelerated depreciation for businesses, and the government's PM Surya Ghar subsidy for residential rooftops, there has never been a better time to switch. As an ISO-certified, veteran-led solar EPC company, Ingenieria (Arrays Ingenieria Pvt. Ltd.) makes the transition effortless, handling everything from feasibility and engineering to procurement, civil works, installation, net-metering and long-term maintenance.
Built for Indian conditions
From the deserts of Rajasthan to the tea gardens of Assam, we engineer ground-mount and rooftop systems that withstand extreme heat, monsoon and dust, maximising generation across every season and terrain.
- Cut electricity bills by up to 90%
- 3–5 year payback, 25+ year asset life
- Government subsidy & accelerated depreciation
A single, accountable partner
No juggling multiple vendors. Ingenieria delivers complete turnkey EPC under one roof, with the discipline, safety standards and on-time delivery our ex-servicemen leadership is known for, trusted by Tata Power Solar, Tata Steel, Tata Motors and more.
- Tier-1 modules & ISO-grade workmanship
- End-to-end approvals & net-metering
- Lifetime O&M & performance monitoring
FAQ
Frequently Asked Questions
Everything you need to know about going solar with Ingenieria.
What does Ingenieria (Arrays Ingenieria Pvt. Ltd.) do?
We are a veteran-led, ISO 9001/14001/45001-certified solar EPC company operating Pan-India. We design and build ground-mount and rooftop solar power plants and handle pile foundations, civil works, chain-link fencing, grid commissioning and long-term operations & maintenance, from a single rooftop to 300 MW utility-scale parks.
How much does a solar power system cost in India?
As a guide, installed cost ranges from about ₹42,000–₹60,000 per kWp depending on whether it is utility ground-mount, industrial, commercial or residential rooftop. Use our free Solar Savings Calculator for a personalised estimate including subsidy and payback.
Is there a government subsidy for solar?
Yes. Under the PM Surya Ghar: Muft Bijli Yojana, residential rooftop systems are eligible for a central subsidy of up to ₹78,000 (₹30,000/kW for the first 2 kW + ₹18,000 for the 3rd kW). Businesses can also claim accelerated depreciation. Our calculator factors the residential subsidy in automatically.
What is the payback period and how much can I save?
Most of our clients see a payback of 3–5 years, after which the system keeps generating largely free power for its 25+ year life, often delivering several times the investment in lifetime savings, plus a major cut in carbon emissions.
Should I choose ground-mount or rooftop solar?
Rooftop solar is ideal when you have unused roof space and want to offset on-site consumption. Ground-mount solar suits larger capacities and open land, delivering maximum generation. We assess your load, space and goals during a free site survey and recommend the optimal mix.
Do you handle approvals, net-metering and subsidy paperwork?
Yes, we manage the complete process: structural & shadow analysis, DISCOM liaison, net-metering applications, subsidy documentation, grid synchronisation and safety-compliant commissioning. It's true single-window, turnkey delivery.
Which areas of India do you serve?
We work Pan-India, with completed and ongoing projects across Haryana, Delhi NCR, Rajasthan, Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, West Bengal, Odisha, Assam and Karnataka, operated from our Greater Noida (UP) corporate office and Madhubani (Bihar) branch.
Why choose a veteran-led solar company?
Ingenieria is founded and run entirely by former military professionals. That means discipline, meticulous planning, strict safety, and uncompromising on-time delivery on every site, the same values that have earned us repeat trust from Tata Power Solar, Tata Steel, Tata Motors, Super Smelters and Jay Shree Tea.
