Sun Photonics commissioned Punjab General Industries’ 9MW(AC) / 12.6MWp(DC) solar plant in Bhiwani, Haryana, under the Green Energy Open Access scheme, a project that redefines what industrial solar execution should look like.
⚙️ Project Overview
Punjab General Industries didn’t want a solar plant that looks good on paper. They needed one that performs, survives Haryana summers, and actually moves the needle on their electricity bill.
This is a 12.6 MWp (DC) / 9 MW (AC) ground-mounted solar power plant, commissioned under the Green Energy Open Access scheme, which means the client isn’t just saving on power costs, they’re trading surplus energy directly on the grid. That’s a different league from a rooftop CAPEX play.
For any factory owner or industrial promoter evaluating a commercial solar EPC company in Haryana, this project is a live case study of what happens when engineering decisions are made with full accountability.

🌐 Scheme: Green Energy Open Access, Government of India
🌞 What Makes This Project Different
Most 10+ MWp projects in Haryana stay stuck at the DPR stage. This one is running.
The plant uses Greev Solar 580Wp and 585Wp bifacial modules — not the cheapest option, but the right one for a site where underperformance compounds over 25 years into crores of lost revenue.
The SINENG SP350K-INHB is a proven utility-grade string inverter. No central inverter single-point-of-failure risk. If one string goes down, the rest of the plant keeps generating.
The 10MVA 33kV step-up transformer (Ynd11d11 vector group) was specified to match DHBVN grid interconnection requirements under the Green Energy Open Access framework — this isn’t a detail most EPC companies think about until it causes a commissioning delay.
Sun Photonics thought about it before breaking ground.
🛠️ Our Role
Sun Photonics handled the project end-to-end as a full-scale industrial solar EPC company in Haryana:
If you’re looking for a government-compliant solar installer for factory who knows the HERC / HAREDA regulatory stack — this is what that execution looks like.
🌱 What This Means for You
Let’s be direct about the numbers.
1.89 Crore units per year at LT level. At ₹7–9/unit (current Haryana industrial tariff range), that’s ₹13–17 Crore in annual electricity cost offset for the plant owner.
Over 25 years — even without accounting for grid tariff inflation — that’s a number that makes the entire project cost look like a rounding error.
And under Green Energy Open Access, the client isn’t locked into self-consumption only. Surplus generation can be sold or wheeled — that’s a revenue lever most rooftop solar setups can’t offer.
For any industrial unit above 500kW contracted demand in Haryana, Green Energy Open Access is the most financially intelligent solar route available right now. Most factory owners don’t know this because most solar companies aren’t equipped to execute it.
Sun Photonics is.
💡 What Visitors Like You Should Take Away
If you operate a manufacturing plant, warehouse, or processing facility in Haryana and your electricity bill is above ₹30–40 Lakh/month — you are the target audience for this project.
🚫 A cheap EPC vendor will save you ₹20–30 Lakh upfront and cost you 10x that in generation loss, O&M neglect, and mismatched grid compliance over the plant’s lifetime.
The Punjab General Industries project isn’t here to impress you. It’s here to show you a benchmark — so you know what to demand from whoever you hire.
💼 Partner with Sun Photonics
Whether you’re evaluating options for a large-scale solar plant in Haryana, need a solar consultant to navigate Green Energy Open Access paperwork, or want a straight conversation about what your project will actually cost and generate —
Sun Photonics Pvt. Ltd. delivers execution, not decks.
📞 Let’s talk numbers — and build a system that performs, not just one that gets commissioned.
“Sun Photonics executed our 12.6 MWp Green Energy Open Access solar project with professionalism and precision. From engineering to commissioning, the project was delivered on schedule, and the plant continues to demonstrate reliable performance and long-term value.”
Project Stakeholder
It lets industries buy solar power directly — skipping DISCOM rates entirely. Punjab General Industries uses this to offset grid dependency and sell surplus generation back. Net result: electricity bill drops dramatically.
At 9MW AC output, 11kV can't handle the load without heavy losses. The 33kV step-up is a grid requirement by DHBVN — without it, the plant doesn't get commissioned. Sun Photonics got this right from day one.
1.89 Crore units/year × ₹7–9/unit = ₹13–17 Crore saved annually. Payback in 4–6 years. Everything after that is pure profit for 20+ years.
One central inverter fails = entire plant down. String inverters mean only one section is affected. For a factory that runs on tight margins, uptime is everything.
If your electricity bill crosses ₹25–30 Lakh/month, yes — and Green Energy Open Access is the smartest route. Sun Photonics has already navigated the HAREDA and DHBVN approvals on this exact project type. You won't be the test case.
