Measured at 10m
— m/s
For most Indian homes, the honest answer is no — and this tool shows you why, using real satellite-derived wind data for your exact location instead of a sales pitch.
Type your city or town. This uses the same NASA dataset used for professional wind assessments.
Enter a location above to see its wind resource honestly assessed.
Estimate only — wind is far more sensitive to local buildings and terrain than solar is. See the honesty note below.
India's own small-wind programme guidance sets a practical viability benchmark of roughly 4.17 m/s (15 km/h) average wind speed at 20m height — and explicitly advises that rooftop-mounted turbines should generally be avoided due to turbulence from surrounding buildings. Independent research backs this up: typical urban wind speeds at 10m are only 3–6 m/s, and building-mounted turbines have repeatedly underperformed in field trials.
That doesn't mean wind is never viable in India — open, elevated, obstruction-free sites in genuinely windy regions can work. It means the odds are stacked against a typical rooftop in a typical city, and this tool checks your specific location against real data instead of assuming.
Wind speed at two measured heights (10m and 50m) for your exact coordinates, from NASA's 22-year satellite/reanalysis climate record — the same class of data used in early-stage professional wind assessments.
We calculate the actual wind shear at your location from those two real measurements (rather than guessing), then estimate the speed at a realistic 20m install height.
Compared against India's own viability guidance — with a clear "not recommended," "marginal," or "worth a professional site survey," never a sales pitch.
Solar irradiance is fairly consistent across a few kilometres, so satellite-based solar estimates (like the ones this site uses for the solar calculator) are genuinely reliable for planning. Wind is different. Wind speed can change dramatically over just tens of metres depending on nearby buildings, trees, and terrain — something a satellite grid spanning tens of kilometres simply cannot see.
For the large majority of Indian homes, rooftop solar remains the far more reliable and cost-effective renewable option — including at most locations this wind tool will check. That's not a house view; it's what the physics and the data consistently show.
