Good not very encouraging all that to recover barely 3kwh per month ....

Especially since at the moment in Chinese gear a guy made a discount
16 185W monocrystalline panels plus a 2800W schneider inverter ... € 2500 incl.

Photovoltaics seem simpler .. However, I will have to break my PEE ...

photovoltaic is simpler than wind ... it is enough that there is no shade to get the right result

Trap of the wind turbine on the roof: a wind turbine works better at 12m on an open ground than at 4m on a roof of 8m

the total height seems the same ... but the 8m of the house is more harmful than useful

a stone wall holds only by its weight: you should not fix anything at the top of the wall, or there is no longer enough weight ... you have to fix the mast low enough to take advantage of the weight that is above. .. and that gives you something to think about: it is often more economical to make a mast completely elsewhere than on an existing house

on the other hand when it is necessary to build something like a garage or a workshop it is interesting to make a construction calculated to serve as support for a mast on the roof: instead of spending stupidly concrete to make the foundation of a mat, we makes a small building seriously reinforced with reinforced concrete

No shade or I wish to install the apenti which would support the solar panels ... along this facade of 16metre long oriented south south west .... it is in full dodger from 10h in winter 8h in summer .. .

I think the meters at 45 ° on a lean of 7m20 long and 2m wide that I would create supported on this wall starting at 2 meter from the ground on 2 height at 45 ° (the window sill is at 3m90 from the ground) ... it will make a shelter for tchernomobile ..When I took this photo I was standing on a 3m50 high wall that holds my land, the ground below is a fallow garden not buildable ... and even if there was an orchard of cultivated before it made shade I would eat the dandelions by the root ... the first poplars are at 200metres ... even in winters it hits by the windows ... The threshold of the window above the poop of zx is 4 meters from the ground ... It just bothered me the natural lighting by the basement bouinottes (which are condemned all winters by opaque insulating panels in glass wool rigid seedbed ..)

Yes, provided that this primary energy (or rather primary power) is abundant ...

And precisely, wind energy is not abundant insofar as one does not have a large three-bladed on a huge mast for free ...

So you have to take great care of what is captured: high-performance components, minimum storage / destocking and MPPT type electronic regulation (maximum power point tracking) ...

Pretty much the opposite of the original project.

I talked about lead-acid battery for a first fixed storage before charging the vehicle

this is not the best solution ... the only advantage is that the lead-acid battery being the cheapest it can be oversized to obtain a high efficiency

but the best solution is interchangeable batteries between the fixed station and the vehicle: so as not to multiply the losses

it is difficult to make a large interchangeable battery: too heavy ... but divided into 4 it becomes more practical

the ideal would be a vehicle which does not empty all its batteries at the same time, but gets confused to empty one of the pack first ... so when we do not drive a lot, we only have one or 2 chan manage and not the whole

and even better that we can ride without all the packs at the same time when we only make a short trip: so avoid unnecessary weight!

the ideal is to use the EDF network ...

Put the wind kWh when they are there, take the kWh for the car when it is there ...

What Macro needs is a wind kit and plug into its phase and neutral ...

Good evening, good morning ,

uh remundo when you say that

"What Macro needs is a wind kit and plug in its phase and neutral ..." uh, are you serious ?? :) I think to avoid that someone just faces just plugging in as is, maybe we should give some details :) ... no ?

So sorry if I cut you in your tracks but it is better to prevent than to cure is not it;).

Thank you chatelot for the explanation concerning the batteries (and the others too).

To come back to the subject, nothing prevents you from making yourself fast zef an anemometer with two candies for children, you know you give the chocolate to the compost :) it's not chocolate, and the toy should be seen maybe a child ??? and still too dangerous, plastic with all its phthalates ...

In short you keep take two ping pong balls and you cut them to make half shells that will act as blades, a computer fan and zou a ride in a car etc etc etc ...:) but I don't teach you anything there ... : Mrgreen: : Mrgreen:

Otherwise sometimes the solar panels are indeed very good too, each situation has its own solution.
Between appolon and eole your heart swings ...

Good all but not the pinion : Mrgreen: : Mrgreen: ;)


as chatelot said very well "it is often more economical to make a mast completely elsewhere than on an existing house
"meditated ...

otherwise chatelot without wanting to deviate from the post just an aside on the principle of emptying only a battery to the liver, it is either the trap or the impossibility (it is for my technical culture :) ) ???

I imagine that for a small city girl, the super light kind of thing is this quite possible? Finally when I say citatine it is the size of a vehicle without a license of course :) , a bit twizzy ...
but with wheel motors :) ...


But for that we would have to reverse the trend which is 4 * 4 at the moment ... :| And change the way you see the car and the speed ...

If not last question, no manufacturer does battery in multi packs of small size ???

Problem solved ... It will not be wind but 20m² of photovoltaic with a 2.8kg inverter.
With maybe a reparametrage of the charger of the sax in 10A ... It would take longer to charge but it will not be a problem..Which will be saved on the domestic electricity bill during the full hours of the day even with a deplorable solar production will compensate for the off-peak consumption of the sax ... With 16 monocrystalline panels of 185W max, I still think I can count on an average production of 20kw / h per day ... I'm in the nails or or not???

I made a crobard of the envisaged architecture ..

Christophe if you can switch the subject to the appropriate section ...

It seems optimistic to me as a figure ... (by the way, these are kWh and not kw / h)
It would correspond to an average annual sunshine equivalent to 6h 3/4 maximum sunshine per day :!:

As a first approximation, 1 Wp gives around 1kWh per year (between 850 and 1250Wh depending on the region).
So 16 * 185 Wp gives 2960 kWh per year or an average of 8,1 kWh per day.

Public chat PVGIS, you can calculate the planned production according to the location and the characteristics of the installation (orientation, tilt, tracking, ...)
