What Is a 20kW Solar System?
A 20kW solar system is a full commercial-scale installation. It generates 80–90 units of electricity per day in summer and 55–70 units in winter, producing 2,400–2,800 units per month. The system uses thirty-six solar panels at 550W each (or thirty-four 585W panels), connected to a 20kW three-phase hybrid inverter.
At this capacity, the 20kW system is no longer a household upgrade — it is a business investment. It powers entire factories, shopping plazas, restaurants, warehouse operations, and large residential estates. For businesses paying the commercial tariff of Rs 65–80 per unit, the return on investment is extraordinary — often under 18 months.
Thirty-six panels need approximately 1,200–1,400 square feet of shadow-free rooftop. For businesses without sufficient roof space, Enon Traders also designs ground-mounted systems with adjustable tilt structures. We use Longi, Jinko, and Canadian Solar Tier-1 panels with commercial-grade Huawei, Fronus, and GoodWe three-phase inverters.

Who Needs a 20kW System?
Small Factories & Workshops
Manufacturing units running welding machines, compressors, CNC equipment, and heavy motors. A 20kW on-grid system slashes the commercial electricity bill by 70–90%. Payback on commercial tariffs (Rs 65–80/unit) can be under 18 months — making this the single best capital investment for small manufacturers.
Shopping Plazas & Malls
Multi-floor commercial buildings with centralised AC, elevators, escalators, lighting, and retail loads. The system offsets the building's common-area electricity costs, reducing maintenance fees for all tenants.
Schools & Hospitals
Large schools with 30+ classrooms, labs, and computer facilities. Hospitals and clinics requiring uninterrupted power for life-saving equipment — hybrid with battery backup is essential here.
Large Residential (2+ Kanal Homes)
Estates with 6+ ACs, multiple refrigerators, deep freezers, water pumps, pool equipment, and full electronics. Monthly bills of Rs 80,000–150,000 become zero or near-zero with a 20kW on-grid system.

| Scenario | Monthly Units | Monthly Savings | Annual Savings | Payback |
|---|---|---|---|---|
| Commercial On-Grid (Rs 70/unit) | 2,600 | Rs 182,000 | Rs 2,184,000 | 11–14 months |
| Residential On-Grid (Rs 55/unit) | 2,400 | Rs 132,000 | Rs 1,584,000 | 15–18 months |
| Hybrid Residential (Rs 55/unit) | 2,200 | Rs 121,000 | Rs 1,452,000 | 24–30 months |
| Off-Grid (diesel replacement) | 2,000 | Rs 160,000+ | Rs 1,920,000 | 18–24 months |
The commercial case is extraordinary. At Rs 70/unit, a 20kW on-grid system saves Rs 182,000 per month — the entire system pays for itself in just over a year. After payback, you generate free electricity for 20+ years. For a factory owner, that is the equivalent of adding Rs 22 lakh in annual profit without hiring a single new employee.

From order to working system: 12–16 days. The 20kW installation requires structural engineering, string design, and commercial-grade wiring that smaller systems do not. Enon Traders manages every step. We install across Pakistan — Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, and all major cities.
Frequently Asked Questions
Both. A 20kW system serves 2+ Kanal homes with heavy loads, as well as factories, plazas, schools, and offices. The configuration differs — commercial uses three-phase inverters and may include SCADA monitoring, while residential uses simpler single-line setups. Enon Traders customises the design for each use case.
Usually no. On-grid with net metering gives the fastest payback for most businesses. Add battery only if load shedding causes revenue loss — cold storage, hospitals, restaurants, or IT operations. For offices that simply close during outages, skip the battery and save Rs 800,000+.
At commercial tariffs of Rs 65–80/unit, a 20kW on-grid system pays back in 11–14 months. Residential payback at Rs 55/unit is 15–18 months on-grid. These are among the fastest ROI periods for any business investment in Pakistan.
Yes. Some configurations use two 10kW inverters instead of one 20kW — this adds redundancy (if one inverter fails, the other still generates). Enon Traders recommends this for critical commercial installations where uptime matters.
Thirty-six 550W panels need approximately 1,200–1,400 square feet of shadow-free rooftop. For buildings with limited roof space, we design ground-mounted systems with adjustable tilt structures. Our site survey determines the best approach for your property.
Yes. A 20kW system requires a three-phase connection. If your property currently has single-phase, your DISCO can upgrade it. Enon Traders guides you through the three-phase upgrade process and handles the net metering application afterward.
