Solar EPC Service in Haryana

Let’s face it — Haryana isn’t just a solar-friendly state. It’s one of the most profitable regions in India for commercial and industrial solar energy adoption. Businesses in Gurugram, Faridabad, Panipat, Hisar, Sonipat, Yamuna Nagar, Karnal, Ambala, Rewari and Rohtak face rising daytime tariffs, increasing fixed charges and heavy dependence on grid power.

Solar is the only long-term energy. A properly engineered solar plant cuts electricity costs from day one and locks your power price for the next 25+ years — with an average payback period of 4 to 5 years across most industrial zones in Haryana.

We deliver commercial and industrial rooftop, carport and ground-mounted solar EPC projects designed for Haryana’s load patterns, DISCOM procedures and climate conditions. We also execute government tenders, KUSUM projects and private PPA installations.

High Solar Irradiation Across the State

Haryana receives strong solar exposure, with average daily irradiation of about 5.0–5.5 kWh/m²/day, making it a high-potential state for solar generation.

Under normal operating conditions, a 1 kWp solar system typically produces 4–5 units per day. However, for accurate ROI planning and financial modelling, a conservative generation range of 4.0–4.5 kWh/kWp/day should be used.

Using a fixed assumption of 4.8 kWh/kWp/day across all districts is optimistic and can overstate output in areas affected by shading, dust load, or seasonal variation.

Tariff Pressure Makes Solar a Financial Decision

If you’re running a commercial or industrial unit in Haryana, you already know this — electricity isn’t cheap anymore.

Across DHBVN, UHBVN, and HVPNL zones, power tariffs typically fall between ₹7.5 and ₹11 per unit, depending on your contract demand and consumer category. And while usage changes, fixed charges keep rising almost every year.

That’s exactly why solar shifts from being an option to a business decision.

A professionally designed solar plant helps you:

  • Replace expensive grid power
  • Reduce dependence on DISCOM supply
  • Lock your cost per unit for the next 25+ years
  • Stay protected from future tariff increases

The result? Most projects recover their investment in 4–5 years across Haryana, and in some industrial belts, even faster — around 3.5 years.

Haryana-Wide Solar Policies You Must Know

Haryana has one of the most regulated — yet clearly structured — solar approval systems in India. Depending on where your project is located, your application will fall under either DHBVN or UHBVN, and each follows its own processes and documentation rules.

That means approvals, timelines, and compliance requirements can vary by district — even within the same state.

1. Net Metering & Gross Metering Rules (HERC)

All solar projects in Haryana operate under:

  • HERC Rooftop Solar Grid-Interactive Regulations
  • Latest DISCOM circulars issued by DHBVN and UHBVN
  • Haryana Solar Policy 2023 

What this means for you:

  • System capacity is linked to your sanctioned load
  • Net metering is available for most commercial and industrial consumers
  • Gross metering applies to higher-capacity projects
  • Safety, earthing, and inverter standards are strictly enforced

Important:
Most policy information available online is outdated.
DISCOM circulars change frequently.

Always verify the latest rules before signing an EPC contract.

DHBVN-vs-UHBVN-Application-Process

2. DHBVN vs UHBVN Application Process (District-Specific)

If your plant falls under DHBVN (Gurugram, Faridabad, Hisar, Rewari, Bhiwani, Mahendergarh, Palwal), the approval process typically includes:

  • Online application
  • Single-line diagram submission
  • Structural certification
  • Fee payment and bi-directional meter charges
  • Pre- and post-installation inspection

If you fall under UHBVN (Sonipat, Panipat, Karnal, Kurukshetra, Ambala, Yamunanagar, Kaithal, Rohtak, Jhajjar), the process is similar — but approval timelines and inspection stages vary.

Tariff-Structure-Impact-on-ROI

3. Tariff Structure Impact on ROI

As fixed charges and energy tariffs rise every year, your avoided grid cost rises with them — improving solar returns automatically.

Every ROI model we prepare accounts for:

  • Fixed-charge escalation
  • Grid tariff inflation
  • Seasonal generation variation
  • Demand penalty reduction

This is why accurate modelling matters as much as panel selection.

4. Solar Generation Potential Across Haryana

Average district-level generation (kWh/kWp/day):

  • Gurugram: 4.7–5.5
  • Faridabad: 4.8–5.4
  • Hisar: 5.0–6.2 (highest in the state)
  • Sonipat: 4.6–5.2
  • Panipat: 4.8–5.5
  • Yamunanagar: 4.5–5.0 (higher humidity, lower yield)

For financial modelling, we always use conservative generation values to ensure realistic payback calculations.

Practical Engineering & Design Recommendations
(Haryana C&I Solar)

Prioritise self-consumption

Exporting power should not be your primary strategy. With rising tariffs, maximum internal usage delivers the highest savings.

Use conservative generation values

Plan your project at 4.5–5.0 kWh/kWp/day unless validated by an actual shading assessment.

Choose quality equipment — not just on-paper specs

Substandard modules and unreliable inverters may look profitable in calculations but reduce generation and ROI in the long run.

Conduct a structural audit early

Most delays in Haryana occur due to weak roofing sheets, unclear load capacity or ageing RCC roofs that cannot support mounting loads.

Factor fixed-charge escalation into ROI

This is the most common modelling gap EPCs ignore. As charges rise annually, solar economics become stronger — if calculated correctly.

Why Businesses Across Haryana Choose Sun Photonics
And Stay With Us

Most EPC companies talk about solar as if it’s the same everywhere.
It isn’t — especially in Haryana’s industrial belt, where load patterns, dust levels, regulatory rules, and roof structures aren’t “standard.”
As a solar installation company for large-scale businesses, we know this because we’ve worked across factories, manufacturing plants, mills, cold storage units, institutions, and commercial facilities — and the results speak louder than proposals.

1. You Get Engineering That Affects Your Bottom Line — Not Just a PowerPoint

We don’t copy-paste designs.
Every project starts with shade analysis, structural feasibility, load mapping and real ROI modelling based on current DHBVN/UHBVN regulations.
No inflated ROI numbers. No fantasy generation claims. Just conservative and realistic numbers that you’ll actually hit.

2. The System Fits Your Site, Your Budget and Your Operational Reality

Some businesses run 24/7, some only operate 8–10 hours, some have limited roof load capacity, some need hybrid or ready future-battery alignment. So, we design the system for your reality — not to drag you toward a fixed package.

Whether it’s CAPEX or OPEX, we plan around:

  • Operational hours
  • Load dependency
  • Space constraints
  • Future expansion
  • Budget flexibility
  • Payback expectations
