Industrial system configurations

On-grid or hybrid — which industrial system?

The right configuration depends on your production schedule, grid stability, and demand-charge exposure. We recommend the best fit after a free energy audit.

Best ROI

Industrial On-Grid Rooftop

Panels on the factory roof, connected directly to your 3-phase industrial supply. No battery — maximum kW per rupee. Net metering / net billing with your DISCO.

Range500 kW – 5 MWp
Inverter typeString or central
Payback1.5–3 years

Uninterrupted ops

Industrial Hybrid + BESS

Solar plus lithium/VRLA battery storage. Backs up critical production lines during grid outages, cuts demand charges, and shifts load away from peak tariff.

Industrial-grade engineering

What makes industrial solar different from residential.

MW-scale solar is a different discipline — three-phase power quality, HT interconnection, structural engineering, and SCADA integration are not skills learned on rooftops.

3-phase grid connection & power quality

Industrial systems need three-phase inverter configurations, power-factor correction, harmonic management and NEPRA Grid Code compliance. Our engineers hold PEC EE-11 and HV licences.

MW-scale string vs central inverter design

Above 500 kW we evaluate string-inverter arrays against central topology based on shading, layout, SCADA needs and long-term O&M cost — PVsyst models both.

Industrial structure — hot-dip galvanised

Factory roofs (tin sheet / PEB) need custom structures rated for wind load per ASCE 7. We run roof-load calculations and provide PEC-stamped structural drawings.

SCADA & remote monitoring integration

Systems integrate with factory SCADA via Modbus/RS485 or Ethernet — live generation, consumption, power quality and fault alerts in the control room.

HT grid connection & transformer sizing

Above 1 MW often requires HT connection at 11kV or 33kV. We design the full HT interconnection — transformer sizing, switchgear and protection-relay settings.

Frequently asked questions

What is the IRR on a 500 kW industrial solar system?

For a Pakistani factory on the industrial tariff, a properly engineered 500 kW system typically delivers 14–18% IRR over 20 years, with payback in 4 to 6 years. Exact figures depend on consumption profile, tariff slab, and how much is self-consumed vs exported under net billing.

Are you AEDB / PPIB / PEC certified?

Yes — we operate as a PPIB AEDB Category C-3 listed installer for grid-connected solar EPC. Our lead engineers carry PEC EE-11 (Energy Engineering) registration required for systems above 100 kW. Certification details and registration numbers are shared at the proposal stage.

Can my factory roof handle the load?

Most industrial sheds can take an additional 18–25 kg/m² of solar dead load with proper purlin reinforcement. We perform a structural assessment as part of the engineering scope and reinforce trusses where needed. Where the roof isn't viable, we offer ground-mount on adjacent vacant land.

How long does an industrial EPC project take?

From signed contract to energisation: 200 kW around 30–45 days, 500 kW around 60–90 days, 1 MW around 90–120 days. Engineering and procurement happen in parallel with civil works to compress the timeline.

Do you provide post-installation O&M?

Yes. We offer annual O&M contracts including quarterly panel cleaning, thermal imaging inspections, inverter firmware updates, SCADA monitoring with 24/7 alarm response, and warranty management. Pricing typically PKR 1,500–2,500 per kW per year.

What financing options exist for industrial solar in Pakistan?

Several Pakistani banks (HBL, Meezan Bank, Bank Alfalah, Bank of Punjab) offer SBP-backed solar financing for SMEs and industrial customers up to 5–7 year tenor. We can introduce you to bank partners; final approval terms come from the lender.

Can I export to the grid under net billing if my solar exceeds my factory load?

Yes — exports are credited at roughly PKR 11/unit (the National Average Energy Purchase Price) under the 2026 Prosumer Regulations. This is lower than the old 1:1 net-metering rate, so we right-size systems to maximise self-consumption rather than overbuilding for export.
