Bangalore is one of India’s most active rooftop solar markets. BESCOM has made meaningful progress on net metering processing, the city has a large and competitive installer market, and growing electricity consumption from tech-sector households and home offices makes the financial case stronger than ever in 2026.

Solar irradiance in Bangalore

Bangalore receives average solar irradiance of 5.0 to 5.5 kWh per square metre per day. Despite its elevation, the city has long sunshine hours outside the monsoon, which runs from June to September.

A 3 kW system in Bangalore typically generates 330 to 400 units per month in peak months. Annual generation of approximately 4,000 to 4,700 units is realistic for a quality, well-oriented installation.

What solar costs in Bangalore

System size	Price range in Bangalore (fully installed, before subsidy)
1 kW	Rs 62,000 to Rs 85,000
2 kW	Rs 1.12 lakh to Rs 1.52 lakh
3 kW	Rs 1.5 lakh to Rs 2 lakh
5 kW	Rs 2.3 lakh to Rs 3.15 lakh

Bangalore has a competitive installer market, especially for high-volume residential segments. After the Rs 78,000 PM Surya Ghar central subsidy, a 3 kW system costs Rs 72,000 to Rs 1.22 lakh out of pocket.

BESCOM net metering in Bangalore

BESCOM covers Bangalore Urban and Rural districts. Its solar cell has dedicated processing for net metering applications. Bangalore urban installations typically see net meter installation within 4 to 7 weeks.

BESCOM requires that the rooftop solar system meets specific technical standards including an AC disconnect switch and compliance with BESCOM’s grid interconnection requirements. A registered installer familiar with BESCOM’s process handles this.

After net meter installation, BESCOM issues the commissioning certificate needed to claim the PM Surya Ghar subsidy.

Monthly savings in Bangalore

BESCOM’s domestic tariff for higher consumption households is significant. For a household consuming 400 to 500 units per month, monthly savings with a 3 kW system are typically Rs 2,000 to Rs 3,200.

Payback period in Bangalore is generally 4 to 6 years. The stronger the consumption and the higher the tariff slab, the faster the payback.

What to look for in a Bangalore installer

Bangalore’s installer market ranges from well-established companies with 500 or more commissioned systems in the city to smaller operators. Look for:

Demonstrated BESCOM net metering experience, evidenced by the number of commissioned systems rather than just installed systems.

Panel brands with service presence in Bangalore. Warranty claims for panels are easier when the manufacturer has regional support.

Inverter brands with a Bangalore service centre. Sungrow, Growatt, Delta, and ABB all have service presence in Bangalore.

References from installations in Bangalore apartments or similar properties to yours. Apartment rooftop installations have specific challenges around common area approvals and cable routing that experience navigates faster.

Common questions from Bangalore homeowners

Can apartment owners in Bangalore apply for solar?
Yes. BESCOM allows individual flat owners to apply for their share of a rooftop system with RWA no-objection. Collective society applications have become more common in Bangalore’s large apartment complexes and often get better pricing and more simplified BESCOM processing.

Does Bangalore’s cooler climate affect panel performance?
Bangalore’s moderate temperatures, particularly in winter, are actually beneficial for panel performance. Solar panels perform better at lower temperatures. This partially compensates for lower irradiance compared to hotter northern cities.

Summing up

Bangalore offers good conditions for rooftop solar: competitive installer market, reasonably organised BESCOM net metering, and meaningful electricity tariffs for upper-consumption households. For households consuming 300 units or more per month, a 3 kW system after subsidy at Rs 72,000 to Rs 1.22 lakh gives a payback of 4 to 6 years.
