Riyadh is located in a desert region with:
– High temperatures (often above 45 °C)
– Dry air
– Partly strong, but also strongly fluctuating wind conditions
– Sandstorms
The advantages of the Antaris wind turbines “Made in Germany”, and their use in Riyadh:
1. Robustness in extreme conditions
The turbines must withstand heat, sand and dust. The features of the Antaris wind turbines are as follows:
– Very important, encapsulated generators to prevent the penetration of sand
– Durable materials with robust steel construction including HT galvanized components and stainless steel fittings
– Maximum reduced maintenance susceptibility, as no gearbox is installed
– Special edge protection on the repeller blades to protect against sand abrasion
2. Low to medium wind speeds
In desert regions, the wind is not constantly strong. Therefore, the Antaris systems are suitable because they:
– Start up even at low wind speeds
– Be able to work even in turbulent conditions due to the built-in safety parameters
3. Decentralized energy supply
Such systems are particularly useful in regions outside dense grid infrastructure (e.g. industrial plants, farms, remote buildings):
– Supplement to solar energy (very common in Saudi Arabia)
– Hybrid solutions (wind + PV + storage + sunny island system)
– Problem with PV; due to dust and sand in the air, the modules have to be cleaned with fresh water every 3 weeks or so.
In the current project, the Antaris 7.5 kW on the 21m high mast supplies the telecommunications station with clean energy in a hybrid system.
Joy of the wind with Antaris wind turbines!
