Understand the available space
Usable area is more than the total roof footprint. Obstructions, shadows, setbacks, walkways and equipment access all affect the design. A survey establishes what can be installed safely.
Review the roof and supporting structure
The condition and structural suitability of the roof need assessment. The mounting arrangement must consider wind, water drainage, fixings and service access. These are engineering decisions rather than assumptions based on floor area.
Bring your electricity information
A recent bill, consumer number, DISCOM and consumption pattern help the team understand connection details and energy demand. System sizing follows the assessment; it should not be chosen from roof area alone.
Use the official scheme process
If considering PM Surya Ghar, review current rules on the national portal. Scheme eligibility and subsidy approval are separate from the engineering assessment. Keep sensitive documents for the appropriate official process.
This guide explains general system principles. Final technical suitability and scheme eligibility require project-specific review.
