Off-Grid Power Supply

The island manager SUNNY ISLAND 5048

Good conditions for photovoltaics: with a solar irradiation of 1,520 kWh/kWp, a solar power supply in York is especially suitable. In the village near the Western Australian capital Perth some houses are still without electricity. The best solution: the Sunny Island system from SMA.

In order to ensure highest yields at any time of the day, the operator in York connected the PV modules to a tracking system. The produced solar power is used to supply a residential building, a water pump with water tower as well as a swimming pool with energy.

Sunny Island systems are perfectly suitable: with their excellent quality they provide a stable energy supply in off-grid regions with demanding climatic requirements such as high temperature and air humidity.
