Is Net Metering 2026 Worth It? Complete Guide for Photovoltaics
20/04/2026
What is Net Metering?
Net Metering is a system that allows you to "sell" excess energy produced by your photovoltaics to the grid and "buy" it back when you need it. Essentially, the grid acts as a "virtual battery."
How Does Net Metering 2026 Work?
- You install a photovoltaic system on your roof
- Excess energy goes to the grid and is recorded
- When you are not producing (night, cloudy), you draw energy from the grid
- At the end of the year, a settlement is made — you only pay the difference
Net Metering Installation Cost 2026
| System Power | Cost | Annual Savings |
|---|---|---|
| 5kW | €4,000 – €6,000 | €800 – €1,200 |
| 10kW | €8,000 – €12,000 | €1,500 – €2,200 |
| 20kW | €15,000 – €22,000 | €2,800 – €4,000 |
Advantages of Net Metering
- Lower installation cost — no batteries needed
- Quick payback — 5-7 years on average
- Simple process — HEDNO (DEDDIE) handles the connection
- Subsidies — up to 40% through Exikonomo (Save-Recycle) program
Disadvantages of Net Metering
- Grid dependence — no power during outages
- Tariff changes — electricity prices may change
- Bureaucracy — requires permit from HEDNO (DEDDIE)
Net Metering vs. Off-Grid System
| Net Metering | Off-Grid | |
|---|---|---|
| Cost | Lower | Higher |
| Independence | Partial | Full |
| Payback | 5-7 years | 8-12 years |
| Power outages | Affected | Unaffected |
Is Net Metering Worth It in 2026?
Yes, it is worth it — especially if you don't have large storage needs or if you want a low starting cost. For complete energy independence, an off-grid system with LiFePO4 batteries is the best option.
