Solar Design Karnataka
Energy Usage
Energy consumption patterns in Karnataka reflect the state's diverse climate, from coastal regions to high-altitude areas, with varying cooling and heating needs. The average Karnataka household uses between 8-12 kWh per day, with Bangalore and urban properties typically consuming more for cooling during hot summers. Energy-efficient properties throughout Karnataka often use significantly less through modern insulation, efficient cooling systems, and smart home technologies.
Before installing solar, consider reducing your energy consumption through improved insulation and energy-efficient appliances. This is particularly valuable in Karnataka, where central subsidies make solar more affordable, and reducing consumption can lower required system size and improve returns.
Typical energy usage per person per day in Karnataka:
Note: Actual usage varies depending on property size, building efficiency, climate, and appliances.
Solar System Sizing
You'll need around 3.9kW of solar to match your average consumption in Karnataka. We recommend sizing between 5.9kW and 7.9kW for optimal results, accounting for daily and seasonal variations. Karnataka enjoys excellent solar potential, with most regions averaging 4.5-5.5 kWh/kW/day annually, with consistent generation throughout most of the year.
A 6.6 kW system in Karnataka generates approximately 30.3 kWh daily on average, with seasonal variation from 4.19 kWh/kW/day in December to 4.92 kWh/kW/day in September. Karnataka's excellent solar irradiance, combined with central subsidies and strong solar capacity (9,925 MW), makes solar particularly attractive for homeowners.
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 Karnataka
Solar Battery Sizing
With solar-only (no battery), a 6.6 kW system provides approximately 50% self-usage in Karnataka, depending on your consumption patterns, drawing 50% from the grid. Adding a 10 kWh battery increases energy independence to approximately 99% annually, reducing grid reliance to 1%. Battery storage is valuable in Karnataka, allowing you to store excess daytime generation for evening use and providing backup power during frequent power cuts.
Net metering policies vary by distribution company in Karnataka, with rates typically ranging from ₹2-6 per kWh. Battery storage is particularly valuable given frequent power cuts, providing backup power during outages. Karnataka's strong solar capacity (9,925 MW) and focus on renewable energy reflect the state's commitment to clean energy.

Solar & Battery System Cost Karnataka
Understanding Solar & Battery System Costs
A 6.6 kW solar system in Karnataka costs approximately ₹493,284, while adding a 10 kWh battery increases the total to around ₹994,849. Karnataka offers central subsidies up to ₹78,000 for rooftop solar under PM Surya Ghar Yojana, with the state having a strong focus on renewable energy initiatives. Solar-only systems typically pay for themselves in around 8.4 years in Karnataka, whilst adding battery storage usually extends payback but significantly improves energy independence. Karnataka's combination of excellent solar potential, central subsidies, and economic strength makes solar particularly attractive, with many systems achieving payback in under 5-7 years.
The cost breakdown shows estimates for equipment costs, installation labour, and applicable taxes. Adjust system size and battery storage to see how it affects total investment and payback periods. Karnataka has excellent installer coverage, with qualified installers operating throughout Bangalore, Mysore, and regional areas, providing competitive pricing and quality installations.
