Solar & Battery Installation Kolkata Local Installers & Quotes
Solar panels perform well in Kolkata, with production peaking during April and remaining useful even in December. For a typical household using 9 kWh per day, solar can substantially lower electricity bills and provide greater energy independence.
Solar Design Kolkata
Energy Usage
Properties in Kolkata average around 9 kWh daily electricity consumption — and with electricity costs continuing to rise, solar can make a real difference to household budgets. Typical homes consume approximately 9 kWh daily on average, though well-insulated properties with efficient appliances often use significantly less.
Reducing your energy consumption before installing solar can lower your system size requirements and improve returns. Consider upgrading insulation and switching to energy efficient appliances first.
Typical energy usage per person per day in Kolkata:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
To offset your average consumption, you'd need roughly 2.4kW of solar capacity. Sizing your system between 3.6kW and 4.7kW accounts for daily and seasonal variations in solar generation.
A 3.6 kW system in Kolkata generates approximately 16.2 kWh daily on average, with seasonal variation from 3.90 kWh/kW/day in December to 4.89 kWh/kW/day in April.
Solar & Energy Savings
Calculate Heat Pump & EV Savings
Electrify your home by replacing gas heating, petrol vehicles, and other fossil fuel appliances with electric alternatives powered by clean solar energy. This delivers significant additional financial savings and substantial carbon emission reductions. Our calculator helps you compare costs and model the financial impact of switching to electric appliances and vehicles.
How Solar Reduces Your Electricity Bills
The calculations below show how your electricity bills change with solar. Your Old Bill of - per month (- annually) is calculated from your total energy consumption multiplied by the grid electricity rate. Your New Bill of - per month (- annually) accounts for solar generation, the percentage you use directly (self-consumption), remaining grid consumption, and feed-in credits for excess energy exported to the grid. This results in monthly savings of - (- annually).
Battery Storage Kolkata
Solar Battery Sizing
The 50% self-use figure reflects how much solar generation aligns with when you actually use power — shifting more usage to daylight hours can improve this without adding panels. With a 10 kWh battery, your 3.6 kW system can power your home well into the evening, bringing grid reliance down to approximately 1%.
Accurate battery savings and ROI require the full Photonik design platform for comprehensive calculations.

Solar & Battery System Cost Kolkata
Understanding Solar & Battery System Costs
A 3.6 kW solar system in Kolkata costs approximately ₹295,690, while adding a 10 kWh battery increases the total to around ₹820,584. The 10.9-year payback estimate is based on current electricity prices — if rates continue rising, as they have historically, your actual payback could be even faster.
These are estimated costs — actual prices vary based on your roof type, equipment choice, and installer. We recommend getting at least three quotes to compare for your Kolkata property.
