Answer:
are more anonymous.
Explanation:
When any government provides any subsidies in the purchase of anything or provides a tax subsidy, the cost to the subsidy is not actually beared from the purse of the government. It is the public's money in some tax form that the government will pay for the cost of these tax subsidies.
Thus in the context, when the United States have provided a $5 billion dollar tax subsidy on the manufacturing of domestic solar panel, the bearers to the cost of this tax subsidy will be the citizens of US and will be anonymous.
Hence the answer is ---
are more anonymous.
