Recovered detail

Additional technical notes

Concise system facts recovered from the historical project record. Treat these as historical unless a newer primary source confirms them.

  • Storage

    Storage: 212 kWh Rolls Surrette FLA [1]

  • Generation

    Hydro: 3 x Hydro generators, 110 kW (Major renewable energy source) providing sufficient power most of the year, except in summer months [1]

  • Generation

    Wind: 4 x Proven wind turbines connected to Windy Boy 6000A, 24 kW (Second largest renewable resource), providing power throug entire year, lowest yield in summer [1]

  • Generation

    PV: 165 Watt modules with 3 Sunny Boy 3000, a 10 kWp (Smallest renewable resource), provides additional power in summer months- upgraded to 32kW in 2010 [1]

  • Generation

     Diesel Generator: 2 x 64kW, primarily backup [1]
