What Is 3kW Solar System?
A 3kW solar system is our most commonly installed residential capacity across Lucknow, Ayodhya and Kanpur, typically generating enough power to substantially offset the electricity consumption of a 3-4 BHK home with standard usage including a few air conditioners or coolers.
Benefits of 3kW Solar System
Fits Most Independent Homes
3kW is the capacity most independent houses and larger apartments in UP are sized for.
Moderate Roof Space Needed
Requires roughly 250-300 sq ft of shadow-free rooftop area — achievable on most standard plots.
Strong Subsidy Eligibility
3kW systems commonly qualify for meaningful government subsidy support, subject to current scheme rules.
Balanced Cost & Output
Sits at a practical middle ground between minimal 1-2kW systems and larger 5kW+ installations.
Fast Installation
Typically installed within 3-7 days from material delivery to commissioning.
Straightforward Net Metering
3kW is a standard, well-understood capacity for DISCOM net metering approval.
