A practical checklist before planning rooftop solar

A rooftop solar project works best when the early decisions are based on the building, the electricity bill and the owner’s long-term expectations—not only on the advertised system size.

Start with the roof and the load

Check the usable shadow-free area, structural condition, orientation and access for installation and maintenance. Review at least twelve months of electricity bills so the proposed capacity reflects actual daytime consumption and permitted export rules.

Confirm approvals and responsibilities

Ask who will manage the DISCOM application, net-metering documents, safety approvals and commissioning. If a subsidy or financing option is relevant, verify current eligibility and timelines on the official portal before committing.

Compare systems, not just module wattage

Review the module, inverter, mounting structure, protection equipment, monitoring platform, warranties and service response together. A dependable proposal should explain expected generation, exclusions, handover documents and the maintenance plan in plain language.
