Advice for micro wind for electric car

[Macro]

I do not have a swimming pool..the goal was just to recover heat under these panels Which in any case is lost..But I suppose that if this air gap is ventllée there must not be much to scratch ...

For the cooling of the panels in the event of strong sunshine ... to gain what ??? 300Wh per year ???

Remundo announcement 5 to 20% increase in annual production.
So in your case, a hundred kWh.
Compare with the cost of installing / maintaining the cooling part.

For Remundo. No, I do not reinject it into the EDF network, which is too complicated and too expensive ... Already, with just € 420 in electricity savings per year, it will take 8 years to amortize the purchase of the kit ...

Well, it's not a good financial idea not to inject on the network, especially photovoltaics.

Do not complain after you amortize in 8 years while at the PV rate for example at 20 ct € / kWh instead of 10, you amortize in 4 years.

And on top of that, you'll get bored with your inverter "rockers" ...

And at the same time, you may not have all the power you want (15A for 6 to 8 hours) to recharge your Tchernomobile ...

Anyway, I kind of feel like you're looking for the wrong choices and trouble. Now do what you want.

On the other hand, one should not underestimate the fact that the regulatory constraints linked to network injection prohibit practically any realization carried out by an individual ... and that the passage by a professional increases the bill (in addition to deprive of the pleasure of the realization and precise knowledge of the installation).

Regarding the roof, an individual can do it by taking a little care, possibly with a "carpenter friend".

The sensitive point is the electrical installation. You pass a certified PV electrician; there are some cables to pass, some surge arresters to put; it's not a fortune (X00 €),

or you call someone who knows how to do and who helps you against "a beer and a hen" and then you have to call Monsieur le CONSUEL who takes 150 € per visit.

"The investment" is worth it in PV. Selling the entire production for 2 to 3 times more for 20 years is another thing to row in network parity with poor performance installations and other "rockers" on such and such an inverter.

PV sold at network par is currently very very long to amortize for a small roof installation.

Then there is the other "solution", not legal but technically operational, it is to inject the inverter directly on the phase and the neutral of the house without asking permission.

Except that at my place ... I have the three-phase and an electronic meter ... So to reinject the sauce it will not be easy easy ...

does the inverter synchronize with the phase to which it is connected?

Will be a schneider sun sunesy 2800 it is intended to be connected to the network according to the technical sheet ...

yes, you can put a single-phase inverter on one of the 3 phases of your house, with a common neutral of course. Any “standard” injection inverter is synchronized with the phase it is given to “eat” and automatically turns off if this phase disappears.

As long as during this phase, you consume more than you inject, the consumption meter will only record the difference = consumption - production.

I don't know how "modern" electronic meters react when there is a net injection of power into the network. My intuition is that they are content to not count it, so a gift for our national electrician. But I don't have confirmation of this

Whereas before, and if you had a disk counter, it would just turn backwards, slowly. Financially, the sale of kWh is at the same price as the "traditional" purchase in this situation, but it is prohibited!

According to EDF contracts, any "wild" injection is prohibited. If I were you, I would ask for a 15A / 220 V single-phase injection meter and a connection contract for the total production sale of your PV hangar.

There is another option which is the "sale of surplus production", but in your case, not sure that it is financially worthwhile.

The sensitive point is the electrical installation. You pass a certified PV electrician; there are some cables to pass, some surge arresters to put; it's not a fortune (X00 €),

The certified electrician who agrees to do only this (small) part of the site, it must be found ...

or you call someone who knows how to do and who helps you against "a beer and a hen" and then you have to call Monsieur le CONSUEL who takes 150 € per visit.

The passage of the consuel on an installation carried out by a non-professional, it can quickly resemble the obstacle course ...
If there are 4 comments to make, some make it a point to make only one per visit

Unless you have knowledge (certified electrician or consuel ), I find that there are only two really viable solutions: having everything done by a professional or not selling your production.

What is crazy..It is that the more I cause it ... The less I want to ...
I have the vague impression that when you don't have a big means or don't want to go into debt over 20 years the best way to do something good with a little money and good will ... is to give everything to charity ...
