Kolkata Solar Data: Annual Sun Hours & Production Potential
Solar Overview
Solar panels in Kolkata receive approximately 1,822 sun hours per year, achieving peak output during April. At 22.57°, solar panels receive consistent irradiation throughout the year, with production variation typically under 10%. The moderate solar resource in Kolkata requires optimization of system design to maximize energy production and economic returns.
Geographic Impact
Located at 22.5726° latitude and 88.3639° longitude, Kolkata's geographical position significantly impacts its solar potential. At 22.57°, solar panels receive remarkably consistent irradiation throughout the year, with monthly variation typically under 10%.
Rating Methodology
Kolkata receives a "Average" rating for solar potential, derived from comprehensive analysis of 1,822 annual sun hours, 27.4°C average temperature, and geographic factors. High temperatures can slightly reduce panel efficiency but are offset by abundant sunshine. Kolkata's solar conditions enable systems to generate 1,000-1,200 kWh per installed kW annually, supporting meaningful energy bill reductions.
Understanding the Data
The chart provides a visual breakdown of solar irradiation by month for Kolkata. The data shows well-distributed solar production across months, with April showing peak irradiation. These monthly variations directly impact solar panel tilt angle selection and overall system design considerations.
💡 Tip: Solar panels in Kolkata may benefit from elevated mounting to improve air circulation and reduce heat-related efficiency losses during peak summer months.
