Why does the US need to have an internationally competitive solar export industry? We can't beat China and a lot of other countries on labor costs so unless we go crazy with automation or have some research breakthroughs for significant solar efficiency vs cost, it would never be a huge win regardless of policy. What we do need is a domestic production base for domestic usage so that solar can't become a negotiating tactic used against us, or a hindrance if international relations collapse. Arguments about current exponential growth not being fast enough don't land with me.
