1. Solar System Cost for Factories (Industrial Solar)

Industrial/large commercial solar systems (e.g., rooftop or ground‑mounted) are priced per kW (kilowatt):

📌 Typical CAPEX (Capital Cost) in India (2025):

₹35,000 – ₹50,000 per kW installed for industrial systems. Synergy Solar
Larger systems (100 kW to 1 MW+) often lean to the lower end of this range because of scale. Shyvon Power

Example:

100 kW system ~ ₹35–50 lakh
250 kW ~ ₹95–105 lakh
500 kW ~ ₹1.8–2.0 crore
1 MW ~ ₹3.5–4.0 crore (CAPEX estimates vary by installer) Shyvon Power

💡 Roof type, panel quality, inverter type, and complexity will influence exact quotes — so always get multiple vendor bids and check references. Synergy Solar

2. Return on Investment (ROI)

Solar for industries typically delivers strong financial returns:

Annual ROI: ~15%–30%+ per year in many cases. Synergy Solar+1This is higher than many traditional business investments — partly because electricity costs for industrial users are high (often ₹8–₹14/unit). Shyvon Power

ROI comes from reduced grid electricity bills rather than selling power (unless you enter private PPA/third‑party models).

3. Payback Period (Break‑Even)

The payback period is typically:

Industrial Solar Payback (India, 2025):

Rooftop solar (grid‑tied): ~3 – 4.5 years
Ground‑mounted systems: ~4 – 5 years
With battery backup: ~5 – 7 years (batteries increase upfront cost) Shyvon Power

⚡ Why it’s short:

Higher electricity tariffs for factories → bigger savings per unit. Shyvon Power
Competitive equipment pricing. Soleos Energy
Low operating costs (~1–1.5% of CAPEX annually). Shyvon Power

Once payback is reached, generated power is effectively “free” electricity for the remaining ~20+ years of panel life. Synergy Solar

4. Example ROI & Payback Calculation (Industrial)

📍 Example — 100 kW Rooftop Solar (Indicative)

Metric	Value
Installed cost (100 kW)	₹40–43 lakh
Annual generation (est.)	~1.4 lakh units
Industrial tariff	₹10/unit (approx)
Annual savings	~₹14 lakh
Payback	₹40 lakh / ₹14 lakh ≈ ~3 years

🔁 Payback accelerates if your tariff is higher or if you install during high sunlight months. Shyvon Power

5. Taxes, Incentives & Other Benefits

While large industrial rooftops usually don’t get direct MNRE subsidies like homes do, there are financial/tax incentives:

✔ Accelerated Depreciation: Up to 40% in the first year → reduces taxable profits and improves ROI. Synergy Solar

✔ Reduced GST/input tax credits: Can lower net project cost. solarfacts.in

✔ Net or group net‑metering: Allows export of surplus and accounting to reduce grid consumption cost in some states/locations. solarfacts.in

6. Sizing & Practical Tips for Factories in Faridabad

📌 Sizing

Match system output to daytime load — factories use most energy during the day, so sizing to production schedule maximizes savings. Heaven Designs
Typical industrial roofs have space for larger systems (hundreds of kW).

📌 Maintenance

Keep panels clean (especially in dusty industrial areas).
Consider AMC (annual maintenance contract). Synergy Sola

📌 Vendor Selection

Get at least 3 competitive quotes from reputable solar EPC companies. Justdial
Check local installers (e.g., in Faridabad‑Delhi NCR region), their financing support, and warranty terms.

Summary: Industrial Solar Economics (Faridabad)

Aspect	Typical Range/Estimate
Cost per kW (CAPEX)	₹35,000 – ₹50,000
ROI	~15%–30% annually
Payback Period	~3 – 5 years
Panel lifetime	25+ years
Operating costs	Low

✅ Solar for factories is often one of the best investments today — cutting electricity costs, improving sustainability, and stabilizing energy budgeting for decades.
