Right, but we still have these giant solar energy plants, as well as the rest of the generation, transmission, and distribution infrastructure, under the control of the capitalist class. While it’s absolutely fantastic that solar-photovoltaic power generation is technically available for the masses, it is still a democratic exception to the capitalist reality.

Like I’m not saying that solar power is not democratic, and I agree with you that it is, but that individual acts of democracy are not sufficient (but are still necessary) to change the reality of capitalist power production.
