Cheap Chinese solar panels are good

A group of European Union parliamentarians have added their voices to calls from climate action groups and much of Europe's solar industry for an end to punitive tariffs on Chinese solar power equipment.

A letter signed in December by 22 members of the European Parliament, including the vice-chairs of the energy and international trade committees, helps to explain.
