2 kW solar panel price in Guwahati with subsidy
The short answer
A 2 kW rooftop solar system in Guwahati costs about ₹1,16,000 installed and ₹50,000 after the ₹66,000 PM Surya Ghar subsidy. It generates roughly 202 units a month — about ₹1,374 worth at Guwahati’s average tariff of ₹6.8/unit — and breaks even in around 3 years.
Guwahati ranks 91 of 95 Indian cities covered here on annual irradiance (4.24 kWh/m²/day) — peak sun in April, May and July, weakest stretch in January and October, which is the profile the 202 units/month figure above is averaged from.

The 2 kW breakdown for a Guwahati 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 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.

How long does installation take in Guwahati?

When does solar perform best and worst in Guwahati?
Guwahati is the exception to the usual Indian pattern — its weakest sun is January and October, during the northeast monsoon, not during the July rains most of the country plans around. Peak generation is April, May and July. A 2 kW system is sized on an annual average of 202 units a month, so expect more than that through April, May and July and less during the dip.
