The roof is leaking a little,

Leaks to remove by looking for the dots and rplacing or changing broken tiles.
One or two damaged ones are enough to destroy while a few hours to change with scales !!!
This happened to me, with only one broken tile!!!!
Crucial and little work !!
The roof must not leak a little !!!

After dry we can wait 10 years !!

Before the rains of the last few days, did you remove the leaks????

Otherwise your house will not last long!!

Looking at advertisements, I came across these inexpensive wind solar kits to install which can be useful with the mistral and the sun and not too big and therefore free to install in a lost corner!

Even when buying other brands, the interest is to indicate the elements essential to the operation to locate and easy to forget.
They sell all kinds of equipment, such as refrigerators, solar freezers, low consumption, more powerful too, and they have resellers?

Good research Dedeleco!

The fourth link is interesting and Quebecois!

I don't really like 12v installations.

a good converter to make 220 is not that expensive, and can use any cheap normal equipment

in 12v everything is more expensive, the current consumed is enormous, the voltage drops are catastrophic

in 24v it is hardly less worse, and it is very complicated if you have a part of the material in 12 and another in 24

Totally agree: low voltage installations are only of interest in the context of use in a humid environment (boats), moreover the guy I know and who has an autonomous installation (solar + group + 1 ton of batteries) only uses 220...
All low voltage appliances are overpriced...

In 400000V there are still much less losses in the copper wires!!
Apart from a few scents!!
see EDF.

Indeed, we quickly lost by Joule effect in the 12 V wires more than we lose in the converter (typical 92 to 96% efficiency)

Not to mention that in 12 volts, the connections and the switch contacts must be perfect, but in today's household electricity, people want switches that are short throw, soft and quiet.

Unless you work in home automation switching (with good big relays): you already gain 11 to 20 m of wire per switch-lamp assembly in an average house.
