20kW Solar System Price in Pakistan 2025 with Net Metering & Backup Options
Introduction
With rising WAPDA electricity tariffs and increasing demand for reliable power, a 20kW solar system is becoming a smart investment for large homes, commercial buildings, schools, clinics, and small factories. It offers high energy output, excellent savings through net metering, and optional battery backup for power continuity.
At Ocentra Engineering Services, we specialize in high-efficiency solar installations using Tier-1 panels, top-rated inverters, and AEDB-approved net metering setups. In this guide, we’ll cover everything you need to know about 20kW solar system prices in Pakistan (2025), system performance, configurations, and backup options.
What is a 20kW Solar System?
A 20kW solar system can generate approximately 2,300 to 2,800 units per month, depending on panel orientation, sunlight, and region. It comes in two main types:
It’s ideal for 2 Kanal+ homes, commercial outlets, schools, clinics, and offices with high power consumption, especially in major cities like Lahore, Islamabad, Karachi, Multan, and Faisalabad.
Is a 20kW Solar System Right for You?
If your monthly electricity bill is between Rs. 80,000 to 110,000, or your property includes multiple air conditioners, fridges, deep freezers, motors, and other appliances — then a 20kW system is a cost-effective and sustainable choice.
Key Benefits:
On-Grid 20kW Solar System
An on-grid system connects to the WAPDA supply and exports excess energy to the grid. With net metering, your bill can be reduced significantly or even eliminated.
Benefits:
Price Range (August 2025): Rs. 1,580,000 – 1,760,000
Hybrid 20kW Solar System
A hybrid system offers the best of both worlds — solar + WAPDA + battery backup. It provides electricity during outages and supports net metering as well. We provide Three-Phase Hybrid setups, ideal for higher load management and commercial-grade reliability.
Hybrid – Three-Phase:
Price Range: Rs. 1,920,000 – 2,160,000 (Without batteries)
Battery Backup Options
| Battery Type | Description | Additional Cost (PKR) |
| 4 Lead-Acid Batteries | ~200Ah total backup | Rs. 192,000 |
| Lithium-Ion Battery | Dyness / Long-Life Compact | Rs. 255,000 |
