As a domestic p.v. owner, I do consider p.v. ONLY for self-consumption, simply because on scale current grid can't sustain it. Harmonic perturbation and quick output variations are too big issues for today, while for self-consumption p.v. is a very good match:
- I use my energy when I can, pushing me to shifting loads as much as I can, I spend less, witch at today grid rates, at least here in France, it's already sufficient to pay back the investment (with an important note, below);
- the grid get less loads in peak moments, at least in the current state of things, where most loads happen during the day most of the time.
Now the important note: I self-made my p.v. because here it's legal to do so and I spent 11.500€ for a 5kWp/8kWh (and I regret not to have choose 10kWp) while the cheapest offer from a local p.v. company was ~30.000 and the highest ~50.000€. This is simply RIDICULOUS. If we price p.v. at reasonable rates and impose self-consumption current state of things makes p.v. viable and contemporary solve the "issue" of p.v. plant in agriculture and in nature in general, if you can't self-consume you do not install them.
The energy "model" is done just for speculation and does not work for a green transition. We need to push cheap p.v. for self-consumption and focus on load shifting (for instance with serious design of most home appliances) and storage. This or there will be no green new deal in general.
