What you get with a residential solar system
A modern Pakistani residential solar system is no longer just a rooftop array. With NEPRA's SRO 251(I)/2026 Prosumer Regulations shifting the country from 1:1 net metering to net billing, the smartest residential builds now combine on-grid solar with at least a small lithium battery to maximise self-consumption.
Every RaySmartSolar residential install includes:
- Bloomberg Tier-1 N-type TOPCon panels — typically Longi Hi-MO 7, Jinko Tiger Neo, JA Solar, or Canadian Solar (560–625W modules).
- Hybrid-ready inverter — Sungrow, Goodwe, Solis, Deye, or Inverex Aerox depending on your load profile and budget.
- MC4 connectors, DC isolators, AC distribution with surge and earth protection.
- Galvanised mounting structure engineered for your roof type — RCC slab, tin shed, or elevated frame.
- Free site survey + 12-month bill analysis to size the system to your actual load, not a generic kW guess.
- Net-metering / net-billing filing with LESCO, IESCO, MEPCO, GEPCO, FESCO, or your local DISCO.
- Wi-Fi monitoring via the inverter app so you can see daily generation from your phone.
How to size your home system
The two numbers that drive sizing are your average monthly consumption (kWh) and your peak load (kW). A useful starting point from a recent bill:
| Monthly bill (PKR) | Typical units / month | Recommended system |
|---|---|---|
| Under 25,000 | ~300 units | 3–5kW on-grid or hybrid |
| 25,000 – 60,000 | ~600 units | 5–7kW hybrid + 5kWh battery |
| 60,000 – 120,000 | ~900 units | 10kW hybrid + 10kWh battery |
| 120,000+ | 1,200+ units | 15–20kW hybrid + 10–15kWh battery |
These are starting points. We always confirm with a 12-month bill review and a roof shading study before quoting.
What a residential system costs in 2026
Indicative installed prices in Pakistan, April 2026:
| System | On-grid (PKR) | Hybrid + battery (PKR) |
|---|---|---|
| 3 kW | ~300,000 | ~420,000 |
| 5 kW | 650,000 – 900,000 | 850,000 – 1,100,000 |
| 10 kW | 1,400,000 – 1,900,000 | 2,000,000 – 2,500,000 |
| 15 kW | 1,950,000 – 2,600,000 | 2,700,000 – 3,400,000 |
| 20 kW | 2,500,000 – 3,300,000 | 3,500,000 – 4,400,000 |
Final price depends on panel brand, inverter brand, mounting complexity, cabling distance, and battery chemistry. We give you a written, itemised quote — never a verbal range.
On-grid vs hybrid — which is right for you?
Before February 2026 the answer was almost always on-grid: you exported every spare unit at the same retail tariff you paid. Net-billing changed that calculus.
- On-grid only still makes sense if you have a daytime-heavy load (a home office or shop), a small budget, or you signed a net-metering agreement before 9 February 2026 and were grandfathered into the old export rate.
- Hybrid + battery is now the default for most new buyers. The battery captures excess generation that would otherwise be exported at the lower net-billing rate, and also keeps essential loads running through loadshedding.
For a deeper breakdown see our hybrid solar page or the net-metering & net-billing service.
Our installation process
- Day 1 — site survey. We measure usable roof area, check shading, and review your last 12 months of bills.
- Day 2–3 — engineered quotation. Design, equipment list, savings projection, locked pricing in a clear PDF.
- Day 4–10 — installation. Certified crew on site. Most residential systems are installed and energised in 2–5 working days.
- Day 10–14 — commissioning + DISCO filing. System goes live and we submit your net-metering or net-billing application in parallel.
Frequently asked questions
How much does a residential solar system cost in Pakistan in 2026?
Installed prices in April 2026: a 3kW on-grid system runs around PKR 300,000; a 5kW system PKR 650,000–900,000; a 10kW system PKR 1.4M–1.9M; a 15kW system PKR 1.95M–2.6M. Hybrid systems with lithium battery add roughly 30–40% on top. We give a written, itemised quote after the free site survey.
What is the payback period for residential solar in Pakistan?
For a typical Punjab or Sindh home paying PKR 35,000+ per month in summer, payback runs 3 to 5 years on a hybrid system. The change to net billing in February 2026 means homes with daytime-heavy loads or a small battery still see fast payback; export-only systems pay back slower than they did under the old 1:1 rule.
Do you handle the LESCO / IESCO / MEPCO net-metering application?
Yes — end to end. We prepare the technical drawings, complete the application, pay the concurrence fee on your behalf, coordinate the AMI smart meter installation, and follow up until the bidirectional meter is live. You only sign the documents.
Will my home solar system survive Lahore's 48°C summers?
Yes. Tier-1 N-type panels carry temperature coefficients around -0.30%/°C — they lose roughly 12% of nameplate output at panel temperatures of 65°C, which is normal and accounted for in sizing. Inverters derate at high ambient temperatures, which is why we install them in shaded, ventilated spots — never sealed metal cabinets in direct sun.
Can I add a battery later to an on-grid system?
Only if your inverter is hybrid-capable. Adding a battery to a string-only on-grid inverter usually means replacing the inverter, which is expensive. We default to hybrid-ready inverters on every install precisely so you can add a 5kWh or 10kWh battery later without rework.
What warranty comes with the panels and inverter?
Tier-1 panels: 12-year product warranty plus a 20-year linear performance warranty. Inverters: 5 to 10 years depending on brand. RaySmartSolar workmanship warranty: 2 years. We honour every claim in-house — no waiting on a distributor.
Do you install on tin sheds and elevated structures?
Yes. Roughly 30% of our residential installs are on tin sheds or elevated steel frames over a slab. We use galvanised structures rated for 150 km/h wind loads and never penetrate roofs without proper waterproofing.
