Energy Usage
Your daily energy consumption determines the optimal solar system size for your home in West Bengal. Typical homes consume approximately 15 kWh daily on average, though well-insulated properties with efficient appliances often use significantly less.
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
A solar system sized at approximately 3.9kW would cover your typical daily energy needs. For best results, size your system between 5.9kW and 7.9kW to account for fluctuations in solar output throughout the day and year.
A 6.6 kW solar installation in West Bengal typically produces 29.7 kWh per day on average, with seasonal output ranging between 3.90 kWh/kW/day (December) and 4.89 kWh/kW/day (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
A 6.6 kW solar-only setup in West Bengal delivers around 50% self-sufficiency, leaving 50% dependent on grid electricity. A 10 kWh battery storage system can raise your energy independence to approximately 99% annually, lowering grid reliance to 1%.
