The issue with solar is, that the owner can be a simple home owner putting the panels on their roof. When you add batteries to that, it is entirly possible that they never need to buy electricity from the grid ever again. However we are still talking about some middle class person here, who is not going to be able to afford a lobbyist.

There are other ways well below lobbyist level as well, such a solar and wind cooperatives or some farmer setting up a few installations on his property. They do have more money, but still probably are well below lobbyist levels of money.
