The 1 kW breakdown for a Guwahati home
What it powers: lights, fans, TV, fridge and small kitchen appliances — the essentials of a small home, without AC load.
Roof you need: about 90–100 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 3-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 APDCL after you sign; the subsidy runs through the national portal and reaches your account after commissioning — the full process.
