– Because energy freedom starts at home.
As electricity prices continue to rise and power cuts still affect parts of Sri Lanka, solar power has emerged as one of the smartest investments for modern homeowners. Whether you’re in Colombo, Galle, Kandy, or even Anuradhapura, solar energy isn’t just for businesses anymore — it’s now affordable, reliable, and scalable for homes.
This article will help you understand the basics of solar power, how systems work, and — most importantly — how much you can save with a rooftop solar installation in Sri Lanka.
🔋 Why Solar Now?
In 2025, there are 3 key reasons solar power is gaining momentum in Sri Lankan households:
- High Electricity Bills: Tariff hikes now cost some households LKR 20,000+ monthly.
- Government Net Plus / Net Accounting Incentives
- Price Drop in Solar Technology: Panels and inverters are more affordable than ever.
🌞 1. What Is a Home Solar Power System?
A home solar system captures sunlight and converts it into electricity using solar photovoltaic (PV) panels installed on your roof.
There are 3 types of systems commonly used in Sri Lanka:
✅ Grid-Tied System
- Connects to CEB/LECO grid
- No batteries — uses solar during the day, grid at night
- Excess power sent to grid (Net Metering / Net Plus)
💡 Most urban homes use this setup
✅ Hybrid System
- Grid + Solar + Batteries
- Stores extra power for night-time or power cuts
- Ideal for areas with frequent outages
✅ Off-Grid System
- 100% solar + battery
- No connection to grid
- Used in remote or off-grid areas (high cost)
🧠 2. Key Components of a Home Solar System
Component | Function |
Solar Panels | Capture sunlight and convert to DC electricity |
Inverter | Converts DC to AC (usable electricity) |
Net Meter | Tracks power fed into & drawn from the grid |
Battery (optional) | Stores excess power for later use |
Mounting System | Fixes panels to roof at optimal angle |
💰 3. How Much Does It Cost in Sri Lanka?
System Size | Daily Output | Monthly Avg Units | Estimated Price (LKR) | Ideal For |
1.5 kW | 6–7 units | ~180 units | 575,000 – 625,000 | Small homes, 2–3 people |
3 kW | 12–14 units | ~360–420 units | 875,000 – 990,000 | Medium homes, A/C & fridge users |
5 kW | 20–24 units | ~600–750 units | 1.35M – 1.65M | Large families & partial business |
10 kW | 40+ units | 1,200+ units | 2.6M+ | Villas, businesses, factories |
⚠️ Prices may vary based on brand (e.g., JA Solar, Trina, Growatt, GoodWe), battery inclusion, and structural installation needs.
📉 4. How Much Can You Save?
Let’s break it down for a 3 kW system, which is the most popular among Sri Lankan homeowners:
Category | Value |
Monthly solar output | ~400 units |
Current CEB cost (avg) | LKR 48/unit (Tiered rate) |
Monthly savings | LKR 19,200 (approx.) |
Annual savings | LKR 230,000+ |
ROI Payback Period | 4 – 5 years |
Panel lifespan | 20 – 25 years |
🎯 Over 20 years, you save LKR 4.6 million or more — with zero fuel, zero noise, and minimal maintenance.
📑 5. Available Tariff Models (CEB/LECO 2025)
Model | How It Works |
Net Metering (Old) | Offset units generated vs consumed |
Net Plus | You buy grid power normally, but sell excess at fixed rate |
Net Accounting | You consume solar first, then buy grid power if needed |
📌 As of 2025, Net Plus at LKR 37.50 per unit (selling rate) is the most common program for new users

🛠️ 6. Maintenance & Support
Task | Frequency | Cost/Details |
Panel cleaning | Every 3–4 months | DIY or LKR 1,000–2,000 locally |
Inverter check | Yearly | Covered under 5-year warranty |
Battery maintenance | Depends on type | Lithium = maintenance-free |
Monitoring app usage | Real-time | Most systems offer mobile apps |
🌍 7. Is Your Home Suitable for Solar?
✅ You need:
- 400–700 sq. ft roof space (depending on system size)
- South-facing or East–West roof slope preferred
- Roof without shade (trees, taller buildings)
- CEB/LECO connection (for grid-tied/hybrid)
🏠 Ideal homes: 2-storey or single-floor houses, clear rooftops, open exposure between 9AM–3PM
🧾 8. Is There Financing or Leasing in Sri Lanka?
Yes! As of 2025, several banks and institutions offer:
- Leasing or Green Loans (up to 7 years)
- Rates from 9.5% to 14% annually
- EMI as low as LKR 17,000/month for a 3kW system
- Providers: HNB, Commercial Bank, Seylan, DFCC, and People’s Bank
🎯 LankaFix can assist with bank documentation and proposals
✅ 9. Why Solar is a Long-Term Investment, Not a Cost
Feature | Impact |
Rising electricity tariffs | Makes solar ROI even faster |
Property value | Increases resale value of home |
Environmental impact | Reduces CO₂ footprint by ~1,000 kg/year/system |
Energy independence | Less reliance on CEB & power cuts |
