Solar & Battery Savings in Delhi, India Get quotes from local installers

Design solar and battery systems for Delhi using Photonik's professional design platform. Delhi, India's capital territory, offers strong solar potential and some of the country's most generous rooftop solar subsidies through the MNRE programme. With high electricity tariffs and abundant sunshine, Delhi homeowners can achieve excellent returns from solar installations.

How Solar Reduces Your Electricity Bills

The calculations below show how your electricity bills change with solar.

What drives your savings in Delhi

Delhi’s steep slab tariff structure — from ₹3/unit for basic consumption up to ₹8/unit or more for higher usage — means heavy consumers benefit most from solar, as each unit offset avoids the highest-slab rate. The state offers free net meter installation and an additional ₹2/unit generation incentive for five years on top of the PM Surya Ghar central subsidy. Solar irradiance averages around 5 kWh/m²/day, though air pollution and haze can reduce effective generation by 10–15% compared to cleaner-air states. Limited roof space on apartments is the main constraint in densely built areas.

Your usage & system size Delhi

Energy usage & tariffs

The right solar system size for your Delhi property depends on how much electricity you use each day. The average household uses around 12 kWh per day, whilst energy efficient properties may use only half that.

Running dishwashers, EV chargers, and pool pumps during solar hours can make a big difference — shifting usage to match generation is one of the easiest ways to reduce your bills.

Representative flat export rate (feed-in tariff). What you earn per kWh of surplus solar exported to the grid. Your actual rate depends on your provider, plan, and time of day.

Estimated at 75% of the retail grid rate. A battery lets you store daytime solar and export during expensive peak hours, so each exported kWh is typically worth more than a flat feed-in tariff. Real returns depend on your time-of-use tariff and battery efficiency.

Solar system size

You'll need around 3.2kW of solar to match your average consumption. Systems sized between 4.7kW and 6.3kW perform best, accounting for natural fluctuations in solar production.

With 20.7 kWh average daily production from a 4.7 kW system, most Delhi households can offset the majority of their electricity consumption.

A 5 kW system in Delhi can generate approximately 8047.0 kWh annually based on local sun conditions.

Battery storage

Even without a battery, 50% self-sufficiency from a 4.7 kW system in Delhi means a significant reduction in your electricity bills. 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 sweet spot for most households is 5 – 13 kWh — larger batteries add independence but with diminishing payback, especially where feed-in tariffs are low.
