Use bill, roof and city details to prepare a realistic rooftop solar discussion before the site survey.
Quick answer: A Rajasthan home should estimate rooftop solar from monthly units, sanctioned load, roof area, shade, tariff and subsidy eligibility. A 2 kW to 3 kW system often fits moderate residential use, while 5 kW and above is common for larger homes, offices and societies.
Step 1: note average monthly units from the last 6 to 12 electricity bills. Step 2: check roof area that stays shadow-free between 9 AM and 4 PM. Step 3: match the consumer category and DISCOM because residential subsidy, commercial payback and net-metering paperwork follow different routes.
Step 4: compare the complete installed system, not only panel watt price. Include panels, inverter, mounting structure, cables, earthing, lightning protection, installation, monitoring, warranty and DISCOM coordination.
Step 5: estimate savings after self-consumption and export credit. Payback depends on tariff, daytime usage, system size, subsidy availability, product selection and maintenance quality.
