- Monocrystalline panels are the most efficient and long-lasting but also the most expensive.
- Polycrystalline panels are slightly less efficient but offer a good balance between price and performance.
- Thin-Film panels are cheaper but have lower efficiency and lifespan.
3. Cost Based on Inverter Type
A solar inverter converts solar energy into usable electricity for your home. There are three main types:
| Inverter Type | Best For | Estimated Price (LKR) |
| On-Grid Inverter | Homes connected to CEB/LECO (Net Metering) | LKR 150,000 – 400,000 |
| Off-Grid Inverter | Homes without grid access (Battery Storage) | LKR 200,000 – 600,000 |
| Hybrid Inverter | Homes with both grid and battery storage | LKR 300,000 – 900,000 |
4. Cost of Battery Storage for Home Solar Systems
If you want backup power for night-time use or power outages, you’ll need solar batteries.
| Battery Type | Capacity | Estimated Price Range (LKR) | Lifespan |
| Lead-Acid Battery | 5kWh | LKR 200,000 – 400,000 | 5-7 years |
| Lithium-Ion Battery | 10kWh | LKR 800,000 – 1,500,000 | 10-15 years |
- Lead-Acid Batteries are cheaper but need frequent maintenance.
- Lithium-Ion Batteries are more expensive but last longer and require less maintenance.
