Are tariffs the right answer? That raises the cost of solar, and cheap solar is ultimately everyone's goal. Shouldn't we instead be subsidizing solar production, contingent on companies like Convolt meeting delivery and efficiency targets? Which is to say: Convolt complained about a drop in prices of 50%. Are we really willing—as a country—to double the cost of solar because our domestic companies haven't scaled up? This seems like a recipe for killing momentum around renewables. Moreover, can you put tariffs on panels made domestically by a Chinese company? The panels aren't imported or exported. I suppose you could tariff foreign manufactured panels and components to fund subsidies to domestic companies such that the two equalize in cost.
