The 10 kW breakdown for a Thiruvananthapuram home
What it powers: effectively an entire villa or small commercial establishment — multiple ACs, heavy kitchen loads and pumps.
Roof you need: about 900–1000 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 6-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 KSEB after you sign; the subsidy runs through the national portal and reaches your account after commissioning — the full process.
