The states don't care if you install rooftop solar
... just don't expect to sell your power generation to the grid without paying for upkeep to distribute your generation
... which is why states have added grid fees or other 'disincentives' as many articles on social media claim  ...

IF all homes and all generation was rooftop solar, then many folks would be without electricity, and the price structure would be reversed, so that nighttime would have scarce, high-priced power delivered by expensive and consumable batteries, while daytime on sunny days, power would be more abundant
... without sufficient power at night or on cloudy days, the people would depend on burning down all the trees and vegetation for firewood at to keep warm or return to burning coal
... which rather defeats the 'ideal' of saving the planet with solar
... I suggest people pay their share, do the numbers, understand how electric generation and distribution occurs and imagine what you would do without power at night
... in the mean time, a typical rooftop solar install at a home does not produce enough amperage to start an air conditioner
... and the hotter it gets, the less efficient the solar panels become (same as the grid because heat is the enemy of all things electric),
.... which means on the hottest days, there is going to be a shortage of rooptop-generated power to starting your AC while running your computer and charging your electric car, and you will need a reliable grid to provide power, to everyone, and not just you.

So buy your boutique-priced solar rooftop and enjoy the robust 14-20 amp generation
.... but don't expect other folks to pay for grid upgrades that support your purchase.

Many folks know that electric wires have an amp rating that limits how many amps (current) can flow down the wire
... including a typical 37-strand 15/16" diameter bare aluminum-alloy conductor (wire) that is used for distributing power from the local substation to each home and business
... if more amps (electrons) are getting pushed through the matrix or atomic structure of the conductor, then the conductor begins to get hot,  causing loss that drives up grid costs.
.... to accomodate more amperage, the power company has to either install larger wire or increase the voltage, so the distribution line can carry more electrons without power loss.

If the voltage is increased from 7900 volt to whatever non-standard voltage you think is available, then the substation transformer must be changed to match the turns ratio needed to deliver that voltage, the substation circuit breakers and switchgear changed to match power rating, and each transformer at each home and each business must also be changed.
Plus the wires raised higher off the ground since air is the insulator that helps keep high voltage lines from arcing to earth
... the insulators at each pole would also need to be changed and wires moved farther apart
... which is costly.

If instead the power company installs larger diameter wire to carry more electrons with the same 7900 volt, then substation transformers would need to be changed into higher rating with larger wires for each winding, the substation circuit breakers changed to match the amps, and the insulators on each pole likewise changed to meet the higher power
... and wires raised higher off the ground to prevent arcing to earth
 ... and wires moved farther apart from each other.
... again it's costly
... and this is true whether the grid is supplying power through the transformer to home, or the home is supplying power through the transformer to the grid
... the conductors have a limit to the number of electrons (amps or current) that can pass through a conductor
... exactly like a 12 gauge wire inside your home will heat up and trip the 20 amp breaker if too many amps flow on the wire
... it's fundamental math that controls how electricity generation, transmission and distribution works on the AC side
.... seems logical that when a business model that exists within that fundamental math experiences need for change, then that change will cost money, and if rooftop solar wants to add their generation, good for them, and it's appreciated if they understand how the grid works, and do their part to help
... which starts while facebooks posts that promote rooftop solar as the solution to all energy problems. Notice those posts never talk about the numbers unless there is a rebate or some support mechanism involved. Noting that there are no similar posts about windmill generation, or large commercial arrays. It's always rooftop solar. Why? Because it's a business that pays folk to post their promotions. It is your job as a consumer and voter to differentiat between promotion sponsored by the rooftop solar industry, and more subtle facts of real world physics ... volts x amps = watts
... which some might wish to alter but can't.... not as long as we are bound to the physics of our world.

... and I say the above using Hawaii as example where it was determined that if more than 50% of the homes on a distribution line are generating solar power during a good solar day, it overclocks the distribution wire.
And I might add that Hawaii temperatures are not as high as say Arizon and Texas, nor are the distances or miles needed to distribute power as great
...plus Hawaii tends to have more wind which cools the conductor
... hotter temps lower the ampacity (the amount of electrons that can flow on the wire without overheating the wire) of a wire, while cooler temps, wind and cloud cover increase ampacity so the wire can carry more electrons.
... the longer distances of western states requires higher level of generation of offset power loss caused by length of wire, costing more per mile in western states that in Hawaii, to reach remote sparcely-populated areas

FYI, volts are the force that push electrons through the conductor matrix, and amps are the number of electrons getting pushed, with more electrons flowing when electricity is being consumed. Volts remain relatively unchanged throughout. The more electrons getting pushed through the matrix of a conductor, the hotter the conductor becomes
... this is the result of natural resistance of all materials to the movement of electrons.

Lloyd says, but wait ... amps, are coulombs per second, the RATE of flow of electrical charge, not electrons.

Yes Lloyd, but the flow of electric charge in made up of electrons. Why? Running a magnet over top of a coil of wire dislodges negatively-charged electrons from their orbit around the positively-charged nucleus
... in a process called electromagnetic induction
... the electrons start jumping from atom to atom traveling one direction down the coil of wire
... if the magnet is spinning end to end, and the north and south pole alternately rotate past the coil of wire, it creates alternating current
... where the electrons move one direction when the N pole passes the coil, then slow, momentarily stop, and reverse direction when the south pole passes the coil
... the power company generator has 3 coils of wire located 120° apart
... the magnet passes each coil at a slightly different time
... producing 3 lines of out-of-phase electric power, with 1 wire taken from the end of each coil
... the other 3 ends of each coil are combined into one line called the Neutral that is bonded to the ground rod array
... coulombs is a measure of the magnitude of the current (amps) of negatively-charged electrons oscillating on the wire
... the charge on energized AC electric wire from the grid is always different than charge of the earth, thus electricity will seek to equalize with the charge of earth
... or to any object with unequal charge...
