What solar plant to supply pond pumps

[meerkat]

Hi,

Thank you for your answers. I must say that it cooled me down on this idea ^^

So I will stay at the good old extension

Too bad the idea of ​​autonomy I liked.

Kind regards.

[chatelot16]

for complete autonomy it is the price and the limited life of the batteries which kills the profitability

but since you already have the electrical network complete autonomy is not essential, you can just save the electricity of EDF when there is sunshine

saw the price of the EDF it is necessary that the photovoltaic panel lasts very long to be amortized: but it falls well a solid panel can last very long

the price of electricity is likely to increase, so whoever installs photovoltaic today unprofitable, will be even more profitable to have them in some year

I think even that in a number of years storage batteries will become profitable, as much because of the increase in the price of energy than because of the placing on the market of better battery better adapted to this use

but do not buy cheap batteries today, they will be dead before they become

conclusion if you have money to put in the photovoltaic, puts a small power, just enough to balance your consomation when there is sunshine

if it was to install in an isolated site with high fees to bring edf, the calculation is differnent and the standalone solution can be interresting

Ah yes so run in the day on solar and rock the night or bad days on sector.

So, how many panels should 200 or 400w be? Is there a device that switches the solar power to the sector?

Maybe I should wait until the investment becomes more interesting then.

Thanks for your advices ;)

there is a small inverter that sends all the power of the solar panel in the area, if the rest of your device consumes more the meter counts only the diference ... if you consume less the old counter turn upside down

the new electronic counter does not turn upside down: the energy in excess is a gift for edf

old counters turn upside down

endangered species.

endangered species.

It is regrettable indeed

But the evolution is that we have more and more gadget that consumes a minimum
I have 2 solar panels of 90w each one a grid tie invent solar of 500w (inverter injection network)
Everything is achieved in the house except:
Combined fridge and freezer sideboard
Timer for water heater
Led on / off of the power strips
Wireless bell receiver (chime)
Box sfr + conbine wireless telephone
Infrared sensor of the court..j'en forgetting surely

At the digital meter edf in full sun I consume 1w by the minute.
Not yet managed to block it but it's close.
The investment is 220 € the 2 panels and 150 € the inverter
Add 30 € for the 2 * 10m and 10 € stainless steel solar cabling for the MC4 parallel connection.

This kind of system helps to overcome all small consumptions, after to produce more you have to fall back on a classic installation.
With this kind of system we can do a small installation 600Wc for about 1000 €, I do not know if it's so profitable in France but in Belgium given the current price of electricity and with a slight annual increase is profitable in 6 years, no premium, tax deduction and green certificate.

small edit: when doing this kind of editing, preferably use a dedicated power line and do not forget to place a differential.

It's the small rivers that make the big rivers
The same goes for electric conso
The torrent in question is the electric water heater (on annual consumption)
when not electric heating
Hence my future investment of solar ECS (domestic hot water) electric booster

Obviously there is an 30mA circuit breaker at the fuse box head
Fed up with 300mA chestnuts from edf
Even 3 enclosures with differential 3
1 at the main level
1 in the cellar
1 at first
Convenient to find out where the current is jumping
Style extends into the garden on a stormy day or kids who put 200l on the floor in there bathroom.
My father who cuts the water line to the grinder without cutting the water does not know where the meter is when I'm not there

To return to the subject
I also have the kit 3kw for redemption edf
Problem I produce 4kwh / an for the 3kwh contract
So redemption at 5cts the excess (night rate)
The contract stipulates that all the production goes for edf
For me 3kw it is 3kw sold the rest to me to me
I have 8 panels, I unplug 2 for me
I still sell my contract 3kw and keep me 2 * 180w ridge
And I inject it at 11cts (day rate)

[dedeleco]

Problem I produce 4kwh / an for the 3kwh contract

weird because it does not do much at 0,1 € the KWh, less than 1 € per year! ??????

And I inject it to 11cts

intravenous ???

[plasmanu]

Hum
I am poorly expressed
Edf gives me 2000 € to 68cts the kwh
And pay me the surplus at 5cts out of contract
If I deduct the excess of my daily conso to 11cts that I do not pay
My benefit is double NO
It should be noted that I have the day / night rate
