Keep in mind, with the new law you are talking about, more money will be dumped into the market with no increase in supply.

That is what is called inflation. If people have an extra 7500 to buy solar, then solar becomes up to 7500 more expensive.

This assumes supply is perfectly inelastic. Even assuming, it also ignores the fact that the money is only dumped in one nation.
