An equipment shortlist should explain why each option suits the roof and the customer’s requirements. Instead of publishing an unsupported universal top-five ranking, use five consistent criteria to assess panels offered for a Lahore installation.
Criteria one and two: fit and electrical suitability
First check dimensions against a workable roof layout, including maintenance access. Second confirm the electrical ratings against the inverter design. A module with more advertised watts may also be larger or have different current characteristics, so model identity matters more than a broad brand label.
Criteria three and four: performance documentation
Third review temperature characteristics and the assumptions used in the generation estimate. Fourth examine the applicable product documentation and warranty terms. Manufacturer comparisons should use the same test basis rather than mix a best-case promotional figure with another model’s standard rating.
Criterion five: traceable local support
Establish who supplies the product, what records accompany it and how a claim is handled locally. Compare current offers rather than an old online league table. Sunlight can discuss suitable available equipment and explain its recommendation after reviewing the site and the intended system configuration.
Your practical checklist
- Use one comparison sheet
- Record exact model codes
- Confirm supply and warranty support
What should I confirm before proceeding?
Check all five criteria against the actual products in the quotation.
