Inroduction
Are you planning to install a 3kW solar system in Delhi? If reducing your electricity bills and switching to clean energy is on your mind, a 3kW on-grid solar system is one of the smartest choices for residential homes in the capital. This guide walks you through the cost, government subsidy, expected savings, and everything else you need to know before installing a 3kW solar system in Delhi in 2026.
What is a 3kW Solar System?
A 3kW solar system is designed for homes with moderate electricity consumption. It converts sunlight into usable electricity, allowing your household to run on solar power during the day while cutting down dependence on grid electricity and reducing your monthly electricity bill.
This capacity is generally the right fit for:
- 2–3 BHK homes
- Small offices
- Independent villas
- Retail shops and small commercial spaces
- Families consuming roughly 300–450 units of electricity every month
If your monthly bill regularly falls in this consumption range, a 3kW system is usually the sweet spot between investment and output.
3kW Solar System Cost in Delhi (2026)
The price of a 3kW solar system isn't a single fixed number—it depends on several factors that affect both performance and durability.
- Solar panel brand and technology (Mono PERC, Bifacial, etc.)
- Quality and make of the on-grid inverter
- Type of mounting structure required
- Roof type (RCC, tin shed, or tiled)
- Overall installation complexity
- Warranty coverage and after-sales support
Typical Price Range in Delhi: ₹1.80 lakh to ₹2.20 lakh (before applicable subsidy).
The final quoted price can vary depending on the specific solar panels, inverter, and site conditions such as roof strength and shadow-free area. A professional site survey is the best way to receive an accurate quotation.
Government Subsidy for 3kW Solar Systems in Delhi
Under the PM Surya Ghar: Muft Bijli Yojana, eligible residential homeowners may receive financial assistance for rooftop solar installations, subject to government guidelines applicable at the time of application.
Subsidy eligibility generally depends on:
- Residential property eligibility
