I don’t dispute Chinese manufactures on net dropped the price by about 20% vs the rest of the market and additional competition further reduced prices, the issue is solar prices dropped by ~80% from 2009 to now so that 20% isn’t the root cause.
Put another way if they had been 80% cheaper than the rest of the market a 30% US tariff would have been meaningless.
When you don't have to make a profit and your capital investments are staked by state (both local and national), it's easier to invest large amounts in capacity.
