Robben Island goes solar

SOLAR PV MICROGRID SHOWS THE POWER OF SOLAR PV AND BATTERIES http://www.solafuture.co.za/news/robb... SOLA Future Energy has succeeded in designing and constructing a solar energy microgrid for Robben Island. The system, situated on the World Heritage Site, consists of 1960 solar panels combined with a lithium-ion battery storage facility and smart controllers to ensure a seamless electricity supply, whilst significantly reducing the island’s fossil fuel consumption. An energy usage profile that comprises residential needs, desalination, harbour and offices means that the island uses almost 2M kWh of electricity annually. Commissioned by the Department of Tourism, the solar system is to shift the island’s reliance on diesel towards the sustainable resource of the sun for its energy requirements. The new solar microgrid will produce almost 1M kWh of electricity annually, significantly reducing costs of buying diesel and transporting it to the island. The island is also embarking on a drive to reduce its own electrical consumption. The microgrid consists of three power production elements. The solar PV farm consists of 1960 mono-crystalline modules with a total of 666.4 kW of capacity. The battery bank, consisting of 2420 lithium-ion battery cells, is able to store 837 kWh and output a maximum of 500 kVA. The third power production element is the diesel generators, historically used to produce power on the island. Multiple controllers between these power production elements creates a smart microgrid, ensuring a seamless supply of power. “The microgrid on Robben Island is the largest combined solar and lithium-ion storage microgrid system in South Africa,” said Dom Wills, CEO of SOLA Future Energy, who were responsible for the design and construction of the project. “For Robben Island, the solar microgrid will reduce its fossil fuel consumption by 235 000 litres of diesel per annum or 50% of previous usage. This will result in a reduction the Island’s carbon emissions by 820 tons, as well as a monetary saving. The system will last for 25 years, and will be paid off in 7 years.” The island is a world heritage site and a very sensitive area to carry out construction. Environmental and political considerations meant that the site for the PV farm was carefully chosen. SOLA staff had to also be sent for training to handle penguins, snakes and wildlife as well as archaeological artifacts that might be discovered underground. SOLA Future Energy believes that Africa’s future relies on affordable, clean, reliable and accessible energy. Besides financial savings, Robben Island’s transformation is symbolic: it shows that an affordable and clean energy future is possible for off grid communities. SOLA Future Energy was awarded the contract by the DoT and has carried out the design and construction over the past year. http://www.solafuture.co.za/news/robb...
