Sure, you can do what ever you want on private land - mostly. However, if you want to develop a big commercial solar plant that plugs into the power grid (yes, I know some local utilities buy home excess power, not talking about that) , big commercial plants need permits. Permits are issued by Governmental Agencies. Government Agencies are run by appointees. Trump Appointees. Look what happened to Net Neutrality, killed by Trump (1) appointee Ajit Pai. . Trump is using executive order and cronies till stopped by judges, and then sometimes he doesn't care. SCOTUS recently ruled that some judges are overreaching their authority when stopping Trumps executive orders so this is no where near settled. Given the degree to which the rest of the GOP is nothing more that a Trump Cult, where's a generation of damage that can be done in the next 3-1/4 years. .
