Solar panels kit for self-consumption

[gil210]

Good evening everyone,
New on the forum, I would first like to introduce myself. Young retired from the public service, I now have time to take care of my house (garden, DIY, etc.).
I plan to equip my house with photovoltaic panels;
I live in the East of France therefore, little sunshine.
tomorrow I will receive two different salespeople for a rooftop installation (about 20m2, I think) for a cost of around 12 to 15000 euros, I think too.
My first question is this: is the self-financing system viable? (I sell the electricity to EDF which finances my installation up to the cost).
AND, the other question, (in fact, the main one), I just saw on the net that there are solar panel kits like these:
-http: //www.kitsolaire-autoconsommation.fr/p/kit-l-meilleur-prix/product/74
Could this be a good alternative to a more complex and more expensive installation on a roof?
I have the possibility of installing these panels on the ground, facing south - like the roof for that matter)
thank you in advance for your clarification;
GIL

Others will give you a more technical answer; For my part, I advise you to think about this: it is those who establish the rules of the game who win every time and shoot the chestnuts from the fire to the detriment of those who listen to them ...
I do not know the conditions of the contract, but EDF will probably win on both fronts: it sells you financing and then buys back the KW for a handful of peanuts!

be careful with self financing ... you have to see in whose name is the loan

if the loan is in your name, if the solar production covers the reimbursements so much the better for you, if not you pay ... the supplier of the installation will leave you in your m ..., but if that produces more than the reimbursement you take advantage

Conversely, a company has just visited my house and offers to build an 800 m2 hangar for 8000 euros of various costs, but it is they who will be the owner of the hangar for 30 years, I would only have the usufruct of being able to use the hangar ... if it produces more than expected (99kWp) and they earn money it is for them if it breaks down and they lose it is for them too


conversely I have a neighbor farmer who installed several hundred kWp by borrowing from his name (or on behalf of a company created for the occasion) he carefully monitors production, because if all goes well he earns a little more that the repayment of the loan but if a circuit breaker jumps and it does not turn on quickly enough it loses ... for this kind of big installation he also has insurance that pays in case of a big problem ... but distrust him insurance does not pay in all cases

the purchase price of photovoltaic electricity drops more and more: it is now lower than the sale price: it becomes useless to fire large regulated installations to take advantage of preferential rates ... I hope it will soon be possible to make small installs at no cost, just turn the counter upside down a little

the complexity of the old installation is justified by the purchase price higher than the sale price, which could encourage fraud, buy electricity at the normal price and resell it at the photovoltaic price ... with the photovoltaic price lower than the normal price we returned to the normal situation where the distributor bought at a price lower than the sale!

My previous message was general and was from your point of view.
As EDF has the obligation to buy back, it is not abnormal to charge a low price, especially since your possible production will occur at a period when it will probably be of very little use.
Another point than those raised by Chatelot, is that your sunshine zone, as you know, automatically leads to the operation ...

If it were possible to turn the meters upside down without too many complications and costs, it would be interesting to develop micro-cogeneration, while without this, the electricity not consumed is lost.

[chatelot16]

according to the photovoltaic shed seller I am talking about there will be a new price available in January 2016: variable in real time depending on the market ... it will be possible for photovoltaic producers to choose when to sell or when it must autoconsomer ... I have not yet found info on this new price, but it seems to me to be the right evolution

I hope that since this tariff will no longer have any privileges, the installation will be simpler than for current photovoltaics

Thank you both for your contributions! I think my decision is made: given the purchase price and my sunshine area, the operation is sealed.
What about solar panel kits to install in a garden for a price of around 3000 euros?
(See the URL in the first post)
A small production in self-consumption could undoubtedly lower my electricity bill and would be depreciable in a short time, right?
Thanks again for your help!

With a 1000Wp kit, EDF will rub your hands! you are going to inject lots of current into the network which is completely free for them.
Not ready to be profitable the kit, especially at such a price ...
A self-consumption system should just cover "the background noise", we have already talked about it ... but I think you do not care because I have the vague impression that in fact you are just there to do advertising for your site.

[gil210]

Good evening Forhorse,
No, sorry, you are completely wrong .... I have nothing to do with this site! I discovered this system earlier on the web and, forgive my ignorance, but I am asking!
I know nothing about everything related to energy and therefore to photovoltaics.
I have no idea what 1000Wp can represent…. On the other hand, your remark on "background noise" may interest me.
How much power is sufficient to cover this background consumption? 500 W, 1000 W or, quite simply, this type of system is just a gadget?
Thank you for your contribution!

[chatelot16]

without battery to make self-consumption you must limit yourself to a much lower power, just the power that you are sure to consume

I'm starting to see advertisements for self-consumption systems with lithium batteries, it's even more eccentric! the limited number of cycles of the battery and its price kills the profitability of the system ... with the current batteries the wear and tear of a battery costs about the same price as the electricity that is passed in at the EDF tariff ... so as long as there is no new more profitable battery there is nothing to do ... lithium batteries last a little longer than lead batteries but are more expensive and profitability n is not better

[gil210]

And what do you call "much lower power"? How can I define it?
