Solar installation goes beyond just mounting panels - it's a complex electrical engineering task.
Fires can be caused by poor design, wrong components, inadequate sizing, and unqualified installation but not the solar panels themselves.
A well-designed solar PV system should have:
✔️ Correct cable sizing and voltage drop calculations
✔️ Proper DC & AC protection (fuses, breakers, surge protection devices)
✔️ Quality inverters and original connectors
✔️ Proper earthing and bonding
✔️ Load assessment before system sizing
Cutting corners can lead to overheating, DC arcing, equipment damage, and even in the worst case, fires.
When hiring a solar installer, ask:
Are they certified and experienced in electrical design?
