The 2 kW breakdown for a Tiruchirappalli home
What it powers: a full small household: fridge, TV, washing machine, fans and lights together, with an AC run occasionally in peak summer.
Roof you need: about 180–200 sq ft of shadow-free space. Panels are mounted on a raised GI structure, so you keep usable terrace below.
Money over 25 years: beyond the 4-year break-even, the system keeps producing against tariffs that rise every year. Panels carry 25-year performance warranties; the inverter is the one mid-life replacement (around year 10–12).
Paperwork: your installer files for net metering with TANGEDCO after you sign; the subsidy runs through the national portal and reaches your account after commissioning — the full process.
