Solar & Battery Costs in West Bengal, India System Prices & Installers
Design solar and battery systems for West Bengal using Photonik's professional design platform. West Bengal, with Kolkata as its capital, has growing solar adoption supported by state-level incentives and the central government's rooftop solar programme. The state's good solar irradiance and rising electricity costs make rooftop solar an increasingly smart investment for homeowners.

Energy Usage
Properties in West Bengal average around 8 kWh daily electricity consumption — and with electricity costs continuing to rise, solar can make a real difference to household budgets. Homes that shift heavy usage to daylight hours — running dishwashers, washing machines, and charging EVs during the day — often get more value from every solar panel.
It's worth reducing your energy usage before going solar, as this can decrease the system size you need and improve payback. Focus on better insulation and energy efficient appliances.
Typical energy usage per person per day in West Bengal:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
Matching your daily energy needs requires approximately 2.1kW of solar capacity. Going larger within the 3.2kW to 4.2kW range typically improves long-term value, since solar panels produce well for 25 years or more.
A 3.2 kW solar array in West Bengal delivers approximately 14.4 kWh daily, with generation varying seasonally from 3.90 kWh/kW/day in December up 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 West Bengal
Solar Battery Sizing
Without battery storage, a 3.2 kW system in West Bengal achieves approximately 50% energy self-sufficiency, with the remaining 50% supplied by the grid. Including a 10 kWh battery typically raises annual self-sufficiency to around 99%, with grid reliance dropping to 1%.
The best way to see whether a battery makes financial sense for your West Bengal home is to model it with your actual usage — try the full Photonik design tool for a personalised estimate.

Solar & Battery System Cost West Bengal
Understanding Solar & Battery System Costs
A 3.2 kW solar system at approximately ₹273,528 in West Bengal can pay for itself through reduced electricity bills — often in under 11.4 years. Keep in mind that 11.4 years is an estimate based on current rates. Many homeowners find their actual payback is faster, especially as electricity prices trend upward.
Pricing includes equipment, labour, and taxes. Use the sliders to adjust system size and battery capacity, observing how changes impact total cost and payback.
