Australia’s Largest Rooftop System on the Crowne Plaza Hotel in Alice Springs

Our intent is to minimise the hotel’s environmental impact and carbon footprint by making the property more energy efficient and reducing its reliance on fossil fuels.”

– Lloyd Berger, Owner of Crowne Plaza Alice Springs

In late 2007, the Crowne Plaza Hotel in Alice Springs invested in a full audit of energy-saving possibilities. The audit showed the enormous solar potential of the hotel's location in central Australia. That prompted a vision for a rooftop photovoltaic installation, and soon led to a joint development between the owner of the Crowne Plaza, and the Alice Solar City Project (part of the Australian Government's Solar Cities initiative). SunPower's proposal won the bid for the project because of SunPower's industry-leading technology, the comprehensive warranty offered and the very high return on investment.

1326 photovoltaic panels now generate between 40 and 80% of the hotel's power requirements, depending on the time of year. It is the largest commercial rooftop photovoltaic system in the Southern Hemisphere.
