Start with evidence, not “best solar company” claims

When comparing solar installers in Vellore, Pernambut, Gudiyattam, Ambur or Vaniyambadi, ask for a proposal that fits your roof, usage and budget. A high search position or a “best” claim is not proof of installation quality.

Look for relevant project evidence, clearly identified equipment, written exclusions and a person who will remain reachable after commissioning. Independent customer reviews can help, but ask what work the reviewer actually had completed.

Five questions to ask each installer

  1. Why this system size? Ask how the proposal uses your electricity units, daytime usage and available roof. You should be able to discuss a smaller system if the suggested size exceeds your budget.
  2. What exactly is included? Compare panel and inverter models, mounting, protection, earthing, cabling, taxes and approval responsibilities.
  3. Who handles the work and the service? Ask who conducts the assessment, carries out installation and answers after-sales questions.
  4. What happens during a power cut? A normal grid-connected system does not automatically provide outage backup. Backup requires compatible equipment and a suitable configuration.
  5. What has to happen before subsidy payment? Check current vendor registration, equipment criteria, portal requirements and full upfront funding needs.

What a roof assessment should clarify

A site assessment should consider usable roof space, shade, safe access, structural suitability, panel placement, cable routing and the electricity connection. A calculator cannot confirm these remotely.

For a shared or rented roof, establish who can authorise the work. For a business, confirm the actual tariff category and daytime load pattern instead of applying household savings or subsidy assumptions.

Compare warranties and ongoing support

Ask for manufacturer warranty documents and clarify installation-workmanship coverage separately. Confirm what happens if an inverter or panel has a fault, who raises the claim, and which service or travel charges may apply.

Cleaning and inspection requirements depend on the site. Ask how maintenance will be arranged safely rather than assuming rooftop work is a routine homeowner task.
