The residential solar industry has been through a lot of ups and downs in the past few years. SolarCity was the top solar company in 2014 before running into rising costs, falling installations, and now a rapidly deteriorating business after it was acquired by Tesla.
In a quest to cut the cost of clean electricity, power utilities around the world are supersizing their solar farms.
Nowhere is that more apparent than in southern Egypt, where what will be the world’s largest solar farm — a vast collection of more than 5 million photovoltaic panels — is now taking shape. When it’s completed next year, the $4 billion Benban solar park near Aswan will cover an area 10 times bigger than New York’s Central Park and generate up to 1.8 gigawatts of electricity.
