Is a 3kW Solar System Enough for Your Home? Usage, Savings & ROI Explained
A 3kW rooftop solar system is one of the most popular choices for Indian homeowners, especially for small to medium households looking to cut rising electricity bills. With increasing awareness about clean energy and the support of the government solar scheme for home, more families in Maharashtra are switching to solar as a long-term investment.
But the big question remains: Is a 3kW solar system enough for your home? Let’s break it down, usage, savings, subsidy, and ROI, so you can make the right decision.
What Can a 3kW Solar System Power in a Typical Indian Home?
A 3kW system generally generates approximately 12–15 units/day depending on sunlight availability and installation quality.
This is suitable for homes with:
- 5–6 ceiling fans
- 6–8 LED lights
- 1 refrigerator
- 1 TV
- 1 washing machine
- Mobile/laptop charging
- Occasional mixer/grinder & small appliances
A 3kW solar system is ideal for households with monthly electricity consumption of 200–350 units.
If your monthly bill is around ₹1,500–₹2,500, a 3kW system is usually sufficient.
How Much Can You Save with a 3kW Solar System?
Savings depend on:
- Your monthly consumption
- Unit rate charged by your DISCOM
- Peak sunshine hours
- Whether you use net metering
Most households switching to 3kW rooftop systems reduce their electricity bills significantly.
Typical outcomes:
- Reduction in grid consumption → big drop in monthly bills
- Net metering benefits → excess units sent back reduce future bills
Homeowners usually save 40–70% depending on usage patterns.
Government Solar Scheme for Home
The Rooftop Solar Phase-II subsidy (PM Surya Ghar: Muft Bijli Yojana) supports household-level solar adoption across India.
Homeowners installing a rooftop system through approved vendors & following proper licensing steps can claim subsidies based on installation capacity.
A 3kW system qualifies for central financial assistance (CFA) as per MNRE guidelines.
Important: Subsidy amounts depend on MNRE updates and DISCOM processes. Always verify the latest values through official government portals before applying.
Licensing, Approvals & Net Metering — Why It Matters
Many homeowners underestimate the importance of proper licensing. A legally compliant installation ensures:
- Eligibility for subsidies
- Safety & quality assurance
- Net meter approval
- Seamless inspection workflow
- Long-term system performance
S’unlimited Solar follows all governmental procedures for licensing, which include:
- Site assessment & documentation
- Application filing on the DISCOM/MNRE portal
- Technical Feasibility Approval (TFA)
- Installation as per prescribed standards
- Inspection by officials
- Net meter installation
- Subsidy disbursement (where applicable)
This ensures your system is compliant and subsidy-ready without hassles.
3kW Solar System ROI — How Soon Will You Recover the Cost?
A 3kW solar system typically offers:
- Low maintenance
- High reliability
- Consistent energy generation for 20–25 years
Even after including licensing, installation, and equipment costs, homeowners often recover their full investment in 4–6 years (varies by state, usage, and subsidy approval).
After that, the energy produced is practically free for the remaining system life, making it a strong long-term financial asset.
Is 3kW Enough for Your Home? Here’s How to Decide
A 3kW system is ideal if:
- Your monthly consumption is 200–350 units
- You want to reduce bills significantly
- You have 300–350 sq. ft. of shade-free rooftop
- You want to benefit from the government solar scheme for home
- You want a fast ROI with low maintenance
