Solar: basic questions!

[sicetaitsimple]

a- Neighborhood projects: several citizens from the same neighborhood or from the same co-ownership bring together a large budget for a relatively large installation (eg 500 m² of PV on a roof of a building or a piece of common ground).
Then there is the question of whether we can make group self-consumption, or whether it is simpler and more profitable to resell everything to reduce common expenses,

Self-consumption group is possible under conditions for a short time (see search engine preferred), personally I do not know anything.
But at the risk of being as pampered as Didier (!!!), I think that a project between individuals must present a report boredom / profits particularly monstrous. Anyone who has ever been a co-owner will understand ...
I have the impression that it targets rather groupings between some companies located in the same zone of activity.

Collective self-consumption on existing buildings is unlikely to develop. Even if it's profitable, few co-owners are willing to invest in a PV project that will only pay in 7 years.
Most people manage their money in the short term.

By cons on the new frame it seems more likely. Between buying a property that costs an arm in electricity and heating, and one that costs virtually nothing, the choice is quickly made if the initial additional cost is reasonable.

@sicetaitsimple. Indeed the law of collective self-consumption is especially for the tertiary. For example a shopping center that equips its parking shades and distributes the current in the hyper but also in the clothes shops.

I do not think installing PV on new rack changes much to the heating bill ...

Hello,

In fact, and to summarize the many comments, the issue of solar is still complex!

In my opinion, this is partly due to:

A- as underlined Did67, of human nature which means that the more there are participants on a project, the more there are probabilities of disagreements, (it is the well-known principle of "PFH" - "Fucking human factor"), without forgetting that there is already at the base a first major financial obstacle (solar costs, investments), followed by the question of return on investment which remains unclear. That said, more and more citizens have understood that the collective also had virtues and that fundamentally individualistic approaches were one of the evils of our decadent society.

B- It must also be recognized that the legislator does not facilitate things: the texts are complex, abstract or even esoteric with full of subtleties that only a few specialists understand.

C- Not to mention the slow inertia of the official supplier to agree to let loose on the issue and its monopoly.

D- And finally there are technical questions: as several remarks underline, the fact that a multitude of individual installations re-inject electricity into the network at times not necessarily interesting for all consumers implies more complex management of the network ...

Hope that things are simplified and allow a simpler and more harmonious development of solar ...

I allow myself just a few remarks or complements:

B- it must also be recognized that the legislator does not facilitate things: the texts are complex, abstract or even esoteric. If the texts are complex, it's because the subject is complex! Otherwise it would be settled for a long time!

C- Not to mention the slow inertia of the official supplier .....: which official supplier? If you mean EDF I think they do not care, at least for small projects.Their role is clear, they buy all or surplus, sell it all on the markets, and are compensated for the difference. If you want to say Enedis, that actually impacts them technically and financially, but it's not a supplier.

And I come back to my "courgettes": it is all the same a system (once again for small private individuals systems) which can only live under current cost price conditions by undressing Paul in order to dress Peter, whom Peter does not is a priori not the most to be pitied ..... That the legislator is concerned to regulate a little all that seems to me to be its role.

A small additional note just for fun:

That said, more and more citizens understood that the collective also had virtues and that fundamentally individualistic approaches were one of the evils of our decadent society.

You will hardly be able to do more "virtuous collective" than Enedis, which offers its approximately 35 million customers a single tariff throughout France (with identical power and consumption profile of course), that you are isolated at the end of a line of one km in the middle of the mountains or living in a building in a built-up area.

putting signs in your garden (or on your roof) is like doing a vegetable garden and not going to the market for what is produced on site

If you land on this thread, see the first post on page 6, I developed the analogy with the garden. As long as you produce and consume your own production, nothing to say.

I find this video (13mn41) of a solar installation that I thought was very interesting because concrete, simple and rather well explained step by step.

It shows a small solar installation in an individual that allows to prioritize solar photovoltaic, and switches to the sector as soon as solar does not provide enough. It seems particularly simple and effective.

Other info, here is a Citizen Solar Project : "Creation of a photovoltaic electricity production cooperative"

I'm not a specialist, but even if it seems to work, the concept all or nothing (as I understand it) of solar or EDF seems a little bestial ... It's still a break , even of very limited duration, at each switchover, I am not sure that all devices appreciate on the medium / long term.
And unless hardly eat anything during the day (not a low energy-type stove such device), there will be a lot of solar cycles / EDF, I fear that the batteries do not hold very long.
