A 15kW system is built for large homes with heavy electricity consumption. If your monthly bill consistently exceeds PKR 70,000 and you run 4 or more ACs, this is the system size that covers your full load and sends surplus back to the grid.

Who Is a 15kW System For
This system serves 5-8 bedroom homes consuming 1,500-2,200 units per month. Monthly bills in this range hit PKR 70,000-120,000. Typical homes include 1-kanal houses in DHA, Bahria Town, or F-sectors with 4-6 inverter ACs, multiple floors, and high daytime loads. Families running a home office with servers, or households with electric water heaters and high appliance density also fall into this bracket.
What Is Included
A complete 15kW Solar Citizen installation includes:
• Solar panels: 27-28 Tier-1 panels rated at 550W each
• Inverter: 15kW on-grid inverter or hybrid inverter (single or dual-inverter configuration)
• Mounting structure: Heavy-duty galvanized steel or aluminum mounting rails with wind load calculation
• Wiring and protection: DC/AC cabling, string combiner box, surge protection, MCBs, earthing system
• Net metering application: Full documentation, engineering drawings, and DISCO coordination
• Installation: Professional installation and commissioning included
• SOL AI monitoring: Real-time analytics, generation forecasting, and savings dashboard
15kW Solar System Price Range
• On-grid (no battery): PKR 20-26 Lakh
• Hybrid (with lithium battery): PKR 28-36 Lakh
At 15kW, on-grid systems deliver exceptional value. Net metering absorbs surplus production during winter and weekends, building credits that offset high-consumption summer months. Hybrid systems at this scale typically pair with a 15-20kWh lithium battery bank, enough to run 3-4 ACs through 3-4 hours of load-shedding.
Monthly Generation and Savings
A 15kW system generates approximately 1,950 units per month. At Rs. 55-65 per unit, that produces monthly savings of PKR 107,000-126,000. Annually, that is PKR 12.8-15.2 Lakh. Homes in the upper DISCO tariff slabs save even more because solar displaces the most expensive units on their bill first.
Payback Period
On-grid 15kW systems recover the investment in 2-2.5 years. Hybrid systems take 2.5-3.5 years. After payback, you collect free electricity for the remaining panel lifespan of 25-30 years. At current tariff escalation rates, a 15kW system saves well over PKR 1 crore over its lifetime.
What to Consider Before Installing
A 15kW system needs approximately 975 sq ft of shadow-free roof space. That is roughly a 30×33 foot area. Most 1-kanal homes have this available on a single roof section. Planning points:
• Roof structural assessment: 27-28 panels add significant weight. Our engineering team performs a structural review to confirm your roof can handle the load without reinforcement.
• Three-phase requirement: A 15kW system requires three-phase electricity supply. If your meter is single-phase, plan for a DISCO upgrade before installation.
• Sun hours variation: Quetta and Multan yield the highest per-kW output. Lahore and Karachi produce about 5-8% less. Islamabad and Peshawar see 10-15% less in winter due to shorter days and occasional cloud cover.
• Future-proofing: If you are considering an electric vehicle or additional floors, sizing to 20kW now is more economical than retrofitting.
Solar Citizen's Approach
Every 15kW system we install uses Tier-1 panels with bankable 25-30 year performance warranties. Installation is included at no extra cost. SOL AI provides real-time monitoring of generation, self-consumption, and grid export, giving you full visibility into your system’s performance and ROI progression.
We handle net metering from start to finish. Our engineering team designs each system around your roof layout, structural capacity, shading conditions, and consumption profile.
