Morocco set to become Africa’s solar superpower


19 February 2016

Solar panel technology, perfectly suited to the African climate and topography, is one of the fastest growing renewable energy solutions for the future. And Morocco is leading the way in perfecting solar’s science and industry.

Located near the town of Ouarzazate in the Sahara Desert, the Noor solar thermal project, comprises three exponential phases that will be completed by 2020. According to Nasa, it will be the largest solar energy installation in the world, making it visible from space.

The first Noor 1 phase of the venture was switched on at the beginning of February 2016. It is expected to begin supplying over a million households in Morocco and its neighbours using sun energy gathered from 500 000 solar mirror panels.

The panels gather and concentrate the sun’s energy to heat water that produces steam that powers energy-generating turbines. The advantage of solar thermal power, apart from its limitless source, is its heat storage capabilities. It stores the heat to make energy at night. Unlike conventional photovoltaic (semi-conductor cell) systems, thermal systems don’t suddenly produce less when a cloud passes over.

The solar panel concept is popular in parts of the world where sunlight is constant throughout the year, particularly in deserts. The largest functioning solar panel project is currently in operation in the Mojave Desert in the USA, according to The Guardian.

In 1986, the German particle physicist, Gerhard Knies, calculated that the world’s deserts received enough energy in a few hours to provide for humanity’s power needs for a whole year. The challenge though, has also been successfully capturing the energy generated and transporting it from the desert plants to urban areas.

With growing, adaptable infrastructure, as well in research into the technology, Africa is perfectly suited to lead the way in finding affordable, practical solutions.

Solar thermal energy in South Africa

Weather conditions and topography in South Africa offers perfect conditions for the solar panel concept, with various projects already using the technology in South Africa.

Operational plants in Pofadder, Upington and Groblershoop generate 200MW of power, while new plant constructions in Northern Cape, including the Redstone and Xina CSP operations, will add another 300MW to the national grid over the next three to five years.

The Helio100 project at Stellenbosch University is researching prototype small- scale concentrated solar power for use in the consumer market.

Meanwhile, in Morocco, the first phase of the Noor installation covers hundreds of hectares, but once completed in 2020, Noor will span more than 24km2, an area larger than the country’s capital city of Rabat.

Noor 1 is creating 160 megawatts of power, making it, even in this first phase, one of the world’s largest solar thermal power plants. As Noor 2 and 3 are completed, the energy generation is expected to be 580 megawatts.

Almost half of Morocco’s energy is expected to come from renewable energy, with a third of that from solar. According to the World Bank, Morocco currently imports 97% of its energy. It believes its investment in the solar plant will help to make the country less reliant on those imports and reduce its long-term carbon emissions by millions of tons.

Together with the African Development Bank and the Moroccan government, the World Bank has invested almost $700-million to begin the first phase of the Noor project that will, over the next 10 to 20 years, bring much-needed renewable energy solutions to Africa and the world.
