The ten checks
Run every shortlisted company through this list. Any 'no' deserves an explanation in writing.
- Do they perform a physical site survey before quoting?
- Is the quotation itemised down to cable size and protection devices?
- Do they provide a single-line diagram and array layout?
- Are they AEDB-licensed for net metering work?
- Is the mounting structure specified with grade and coating for coastal Karachi air?
- Are panel, inverter and battery warranties from the manufacturer, not just the dealer?
- Can they show completed Karachi projects you can verify?
- Do they document earthing and surge protection?
- Is after-sales service defined, with a response commitment?
- Do they hand over as-built drawings and commissioning readings?
Why local Karachi experience matters
Roof types, plot densities, K-Electric procedures and salt corrosion behave differently here than in upcountry cities. A contractor who has delivered a hundred systems in Karachi already knows how a Gulshan rooftop shades at 4 pm in December and how a DHA building committee handles structure approval.
After-sales is the real product
Panels get dusty, breakers trip, inverters need firmware updates, and monitoring needs someone to look at it. Ask what happens in year three. At Eco Fusion Solution, cleaning and after-sales visits are available on a per-visit basis — the charges depend on system size and location and are confirmed when you contact us.
