8 Solar Installation Mistakes to Avoid
Top errors Karachi companies make. Learn what quality installation looks like. Avoid expensive fixes later.
❌ Mistake #1: Using Non-Certified Brands
Buying unknown panels "to save money" = spending PKR 500,000 on broken panels in 3 years
❌ Mistake #2: Poor Roof Installation (No Waterproofing)
Drilling without proper sealing = roof leaks during monsoon. Fix cost: PKR 50,000-80,000
❌ Mistake #3: Incorrect Angle/Orientation
Panels facing wrong direction or wrong angle = 20-30% less generation. Lost income over 25 years: PKR 500,000+
❌ Mistake #4: Skipping Inverter Testing
Inverter not tested after installation = fails in 6 months. Replacement: PKR 150,000+
❌ Mistake #5: Bad Wiring Without Earthing
Poor electrical work = fire hazard. Safety issue + won't pass K-Electric inspection
❌ Mistake #6: Missing Warranty Coverage
No written warranty = no recourse when panels fail. Always get 25-year panel + 1-year workmanship warranty
❌ Mistake #7: No K-Electric NOC Obtained
Installation without government approval = illegal. K-Electric can disconnect you anytime
❌ Mistake #8: Cheap Inverter Brand
Non-reputable inverter fails in 3-5 years = PKR 150,000-200,000 replacement. Quality inverter costs 30% more but lasts 15+ years
