Delta Solar PV System installed in Bora Bora Resort
Four Seasons Resort Bora Bora has integrated a 600kWp rooftop solar PV system. A new photo-voltaic system has been installed in the luxurious 5-star French Polynesian resort, allowing it to produce green electricity.
For several years, the luxury hotel complex, located on the South Pacific island of Bora Bora, has implemented an ecological business approach. Renowned for its white sandy beaches, its turquoise water and overwater bungalows, the Four Seasons Resort Bora Bora wanted to go a step further in protecting this stunning environment by investing in a solar PV system.
The beachfront resort decided to pursue a 600kWp commercial photovoltaic system installation to help reduce its carbon footprint and to protect the beauty of its environment. However, the advantages of a photovoltaic system at this particular site extend far beyond the environmental aspects. Bora Bora is a remote island of French Polynesia that produces the majority of its electricity from power plants that run on diesel. Electricity provided by the local utility company, EDT, is very expensive because of the high operating expenses on the island and the high fuel transportation costs to this faraway location. The electricity on Bora Bora can cost up to 41 euro cents per kWh (49.5 francs CFP per kWh). A rooftop PV system would help the resort to better control the costs of its electricity supply.
The PV array was installed on the roofs of two large service buildings inside the resort complex. To accommodate all the solar panels needed, an additional building with an area of 1600m² had to be built.
29 Delta RPI M20A inverters (each with a rated power output of 20kVA) were chosen for this PV project. The RPI-series inverters are ideal for tropical climates due to their IP65 protection rating, which guarantees the units are impervious to water spray and humidity. The Delta M20A inverter offers other benefits in tropical environments, such as full power operation at high ambient temperatures and a rugged aluminium chassis that is highly resistant to sea salt corrosion. Additionally, a maximum efficiency of 98.4% helps to ensure that all the available solar energy from the PV system is harvested.
