From the article: None of this should be seen as a condemnation of solar power, says Balasubramanya. “The fundamental problem is not the solar technology itself.” Whatever the technology, “if the cost of pumping is zero, then people will pump unless some restriction is put on them.” — The article also discusses that the panels are much cheaper to run than diesel and are subsidized by agencies and governments while the diesel pumps are not. So, yes, it’s not specifically about solar but about the economics of solar.
