Technical Advantages

Dragon Product Family

Based on official technical specifications, Dospel Dragon wind turbines stand out due to their extremely low starting speed, which is critical in inland wind conditions.

The devices are 3-phase (AC), work in both Off-grid and On-grid configurations, and have an 8-year warranty. Easy integration with solar panels (Hybrid ready).

Climate: Inland vs Coastal

Average Wind Speeds

Wind conditions are clearly divided into two zones: the windy coast/islands and the calmer inland. Note: The values shown in the graph are monthly averages. During autumn storms and winter cyclones, actual peak wind speeds regularly reach 20–25 m/s. Therefore, the generator must have local durability and automatic storm braking to withstand extreme gusts.

Synergy

Hybrid Solution (Wind + Solar)

At northern latitudes, solar energy is minimal in winter, while wind speeds reach their maximum (Nov–Mar). This makes Dragon wind turbines an ideal component for Off-grid households.

Payback & Nord Pool

Electricity Cost Savings

In 2025, the average Nord Pool exchange price was 8.38 cents/kWh. However, the beginning of 2026 has shown extreme volatility (winter peak periods averaged over 15.4 cents/kWh). Including grid fees, taxes, and VAT, the consumer's final price when buying from the grid is usually around 18–25 cents/kWh, and often higher in winter.
