After decades of global competition and collaboration, many solar markets around the world have reached grid parity—the point at which generating solar electricity, without subsidies, costs less than the electricity purchased from the grid. In other words, solar technology is ready to be a major contributor to solving our planet's energy and environmental crisis.
However, trade protectionism threatens to inhibit the solar industry at the very time when it is breaking through to a new level of global interdependence, collaboration, and maturity.
On October 18, the U.S. government was asked to impose tariffs on imports of Chinese solar cells and modules, based on the argument that China-based producers have been heavily subsidized and are selling solar products at unfairly low prices. Perhaps not surprisingly, some Chinese companies have now asked the Chinese government to impose tariffs on imports of American solar products, arguing that U.S.-based producers have been heavily subsidized, too. And just like that, the production of affordable and competitive solar products has become a political liability in the world's two largest producers and consumers of energy.
