Frequently asked questions
How much does a residential solar system cost in Pakistan in 2026?
Installed prices in April 2026: a 3 kW on-grid system runs around PKR 300,000; a 5 kW system PKR 650,000–900,000; a 10 kW system PKR 1.4M–1.9M; a 15 kW 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 5 kWh or 10 kWh 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.
