A list of company names is only a starting point. Karachi property owners can make a stronger decision by applying the same checks to each installer and retaining the evidence behind the final quotation.
Checks one to four: identity and experience
First match the legal name across the quotation and company documents. Second review the engineering licence and any installer certification required for the work. Third request relevant project examples. Fourth establish who is responsible for the assessment and design. Sunlight publishes its company records and installation photographs for this purpose.
Checks five to seven: equipment and scope
Fifth record complete equipment models. Sixth compare the included mounting, protection, cabling and commissioning work. Seventh identify the backup arrangement and energy assumptions. A system-size label alone cannot answer those questions, and an attractive package description should not obscure important exclusions.
Checks eight to ten: service and terms
Eighth read equipment warranty and workmanship terms separately. Ninth agree payment milestones and the process for changes. Tenth confirm the support contact and handover documents. Apply this checklist to Sunlight and other suppliers alike; it is a selection method, not a claim that a government has ranked installers.
Your practical checklist
- Keep a written comparison
- Check documents and expiry dates
- Ask for an agreed support process
What should I confirm before proceeding?
