Now, a new study published in the journal Nature has calculated that the globalized supply chain saved countries $67 billion in solar panel production costs. The study also found that if strong nationalistic policies that limit the free flow of goods, talent and capital are implemented going forward, solar panel costs will be much higher by 2030.

The study -- the first to quantify the cost savings of a globalized value chain for the solar industry -- comes at a time when many countries have introduced policies that would nationalize renewable energy supply chains in a bid to benefit local manufacturers. Policies such as imposing import tariffs could complicate efforts to accelerate deployment of renewables like solar by raising the cost of production, the study's researchers said.
