Solar potential of Raipur explained
Raipur receives an average of 5.17 kilowatt-hours of solar energy per square metre per day, measured over four decades of satellite observation. In practical terms, every kilowatt-peak of installed PV capacity yields about 1510 kWh of electricity per year here, assuming a well-oriented system with a typical 80% performance ratio. This places Raipur among the stronger solar locations globally — comparable to southern Spain or California.
Frequently asked questions
Is solar worth it in Raipur?
With 5.17 kWh/m²/day of average irradiation, a 1 kWp system in Raipur produces roughly 1510 kWh per year. That is an excellent solar resource — payback periods are typically among the shortest worldwide.
How much electricity would a 5 kW system produce in Raipur?
Approximately 8,000 kWh per year — enough to cover a large share of a typical household's consumption.
What data is this based on?
Long-term satellite observations from NASA POWER (1981–present) and the PVGIS SARAH3 database, assuming a performance ratio of 80%.
