❓ PART 8: FREQUENTLY ASKED QUESTIONS (Real Pakistani Scenarios) 🙋

Q1: How much time does solar installation take? ⏱️

A: Installation takes 3-7 days for residential. Net metering approval takes additional 15-30 days (for systems below 25 kW). 📅

Roman Urdu: Panels lagne mein 3-7 din lagte hain. Net metering ka approval 1 month mein ho jata hai chote systems ke liye. ✅

Q2: Can solar system run AC? ❄️

A: Yes! 1.5 ton AC needs approximately 1.5-2 kW power. A 5 kW system can easily run 2-3 ACs during daytime. ❄️❄️❄️

Roman Urdu: Bilkul chalta hai. 5 kW ka system 2-3 ACs chala sakta hai. Bas system size according to load rakhna chahiye. 👍

Q3: Is battery necessary? 🔋

A: Not necessary. If your area has no or little load-shedding, on-grid (without battery) is best. If load-shedding exists, go for hybrid or off-grid with battery.

Roman Urdu: Battery zaroori nahi. Load-shedding nahi to on-grid lo, sasta hai. Load-shedding hai to hybrid lo.

Q4: Is solar profitable under 2026 new policy? 💰

A: Absolutely profitable. Export rate has decreased but payback period is still 3-4 years. And the system runs for 25+ years.

Roman Urdu: Haan, profitable hai. Export rate kam hai lekin savings ab bhi bohat hain. 3-4 saal mein system ka paisa wapas aa jata hai.

Q5: How many kW can I install on single-phase? ⚡

A: On single-phase connection, you can install up to 5-7 kW maximum. For larger systems, you’ll need to upgrade to three-phase.

Roman Urdu: Single-phase par 5-7 kW tak laga sakte hain. Bada system lage ga to three-phase karwana pare ga.

Q6: What is the life of solar panels? 🌱

A: Good quality panels last 25-30 years. Performance guarantee is 25 years (80% output).

Roman Urdu: Ache panels 25-30 saal chalte hain. 25 saal baad bhi 80% output dete hain.

Q7: Can solar system make my bill zero? 📉

A: With net metering, your bill depends on the balance between generation and consumption. If you generate as much as you consume, bill can be zero or very low.

Roman Urdu: Bill zero ho sakta hai agar aap daytime mein maximum generation use kar lein. Export kam rate par milta hai is liye daytime consumption maximize karna chahiye.

Q8: What warranty comes with solar system? 📃

Panels: 10-12 years product warranty, 25 years performance warranty
Inverter: 5-10 years (extendable)
Battery: 2-3 years (lead acid), 5-10 years (lithium)
Installation: 1-2 years

Roman Urdu:

Panels: 10-12 saal product warranty, 25 saal performance warranty
Inverter: 5-10 saal (extendable)
Battery: 2-3 saal (lead acid), 5-10 saal (lithium)
Installation: 1-2 saal

Q9: How often should panels be cleaned? 🧼

A: In summer (dusty season), every 10-15 days. In winter, every 20-30 days. After storms, immediately.

Roman Urdu: Summer (dusty season) mein har 10-15 din mein. Winter mein har 20-30 din mein. Storms ke baad foran.

Q10: Can I add more panels later? 🔲

A: Yes, but check your inverter capacity first. Inverters have maximum input limits. You may need a larger inverter or a second inverter.

Roman Urdu: Haan, lekin pehle inverter capacity check karein. Inverters ki maximum input limit hoti hai. Aap ko bada inverter ya doosra inverter lagna par sakta hai.
