The desalination project has been constructed for the Municipality of Kimolos by Zillion EPC. Sungrow’s 100kWp photovoltaic system, consisting of 238 units of 420W PV modules, has been installed near the new desalination unit with a capacity of 220 m3/day, (the average consumption of water per person is 0.1440 m3/day), connecting to the low voltage network of the grid, ensuring the uninterrupted operation of the station.
Zillion opted for Sungrow’s SG50CX-P2 string inverters, which are known for their efficiency and reliability, given that the environmental conditions in Kimolos can be fairly harsh, including gusting winds, high temperatures and high levels of humidity, alongside the salty environment.
These inverters are compatible with high power modules (+500Wp) and have smart O&M functions, while they have a robust design certified by IP66 protection and C5 anti-corrosion level. For the communication of the system, the COM100E smart communication box by Sungrow was chosen, providing flexible, reliable and easy operation, along with a high level of protection due to the IP66 design. The products have been delivered via Krannich Solar Greece, Sungrow’s official distributor.
Kimolos lies on the southwest of the island group of Cyclades with a distance of approximately 85 nautical miles to the southeast of Piraeus, the biggest port of Greece. With an area of 34.4 square kilometres, according to the latest census (2021) just over 810 inhabitants live there, a number that increases to many thousands during the summer period, as this beautiful destination attracts tourist from all over the world.
The population growth on the island, in combination with climate change, presents a significant challenge for the water supply on the island, especially during the summer months. One solution is the desalination of sea water, a well-known, but also energy intensive practice that is deployed to address water scarcity globally.
Almost one-fifth of the world’s population lives in areas of water scarcity. It is predicted that many regions in the EU – especially, southern European Member States - will face severe water scarcity by 2050, when water demand is expected to increase by up to 30 percent. Desalination can significantly alleviate this problem, while the use of clean energy for this process can provide a sustainable solution.
“Implementing this project was a true challenge for us, primarily due to its geographical location and the difficulties in connecting with mainland during the winter when the construction took place” said Vasileios Ziogos, Founder and Head Engineer of Zillion. “Additionally, the specific positioning required for the panels demanded careful planning. Nevertheless, the uniqueness of the project and its purpose inspired us to proceed with dedication and determination. By selecting equipment of exceptional quality and reliability, we are confident in its excellent and seamless operation.”
