I wonder what the income distribution on buyers looks like for these different companies, and what proportion of their buyers would be unable to use the tax credit regardless? E.g. if proportion p of your buyers can't use the tax credit and relying on foreign battery production reduces the sticker price at least (1-p) * $7500, you would be net saving your purchasers money if you keep the foreign battery sources?
