Solar & Battery Installation Mumbai Local Installers & Quotes
Rooftop solar is increasingly popular in Mumbai, where homeowners benefit from strong sunshine and rising electricity costs. With typical daily usage around 8 kWh, even a modest system can deliver noticeable savings on monthly bills.

Energy Usage
To choose the right solar system in Mumbai, start by understanding your daily electricity consumption. With electricity prices trending upward, even small reductions in your 8 kWh daily consumption can noticeably lower your bills — and solar takes this further by offsetting much of what you do use.
Future-proofing is worth considering: if you plan to add an EV, heat pump, or pool, your energy needs may grow — and sizing your solar system a little larger now can save money later.
Typical energy usage per person per day in Mumbai:
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 2.1kW of solar capacity. The 3.2kW to 4.2kW range accounts for real-world conditions — cloudy days, seasonal variation, and the fact that panels rarely perform at peak all day.
In Mumbai, a 3.2 kW installation produces around 14.5 kWh per day on average, though output ranges from 4.02 kWh/kW/day during December to 4.90 kWh/kW/day in September.
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 Mumbai
Solar Battery Sizing
With solar-only (no battery), a 3.2 kW system provides approximately 50% self-usage in Mumbai, depending on your consumption patterns, drawing 50% from the grid. The jump from 50% to 99% self-sufficiency with a 10 kWh battery is most noticeable on your evening electricity bills, when rates are often highest.
The gap between December and September production affects how much work your battery does season to season — the full Photonik tool models this for your specific situation.

Solar & Battery System Cost Mumbai
Understanding Solar & Battery System Costs
A 3.2 kW solar system at approximately ₹273,528 in Mumbai can pay for itself through reduced electricity bills — often in under 11.3 years. While batteries extend the payback period beyond 11.3 years, they also protect against future electricity price rises and provide backup power during outages.
The breakdown covers equipment, installation, and taxes. Adjust the system size and battery sliders to see how different configurations affect your investment and payback timeline.
