Rwanda, home to Africa's largest solar power plant, is eager to harness renewable energy to ensure economic development. But its grand ambitions face many challenges. The US$1.3 million plant, known as Jali, is covered in 4,000 solar panels covering 2,880 square metres. It produces 325,000 kilowatt hours of electricity a year - but this is still just 0.1 per cent of Rwanda's total electricity production.
