That's true today, but I bet it won't be in 5 years time. Around this year or last year batteries have hit a price point where they make financial sense for ordinary people, and in a couple of years you'd be mad not to have them if you have rooftop (and somewhere to put the batteries of course).
> Any subsidies for solar power should go to utility grade solar.
At this point, it should probably go towards storage, grid capacity, or things like EV charging infrastructure. Solar generation doesn't need it.
> The consumer rooftop solar cost is usually one of the most expensive ways you can generate electricity
This may well be true, but there are positive externalities:
- It has reduced land use compared to other energy generation methods
- Power is produced near the point of use, reducing transmission requirements
- Most of the cost is labour for installation which creates jobs
Given that rooftop solar usually pays for itself despite being less cost-efficient that other forms of solar, I see no reason to discourage it.
