Grid connection

Conventional AC supply; highest reliability under normal conditions, but the one most exposed to the 2050s disruption assumption (Charter §2).

Regulation (FR example)
Fixed electrical installations must meet NF C 15-100, and a Consuel certificate is required before a new connection is energised. Grid-connected generation requires an Enedis connection agreement.

Note: Cost, carbon and footprint are rated against the other options for this same need, not in absolute terms.

What this page does not tell you

No sizing or quantities: how much a technique yields, and how much a household needs, both depend on the build and the people, so the catalogue compares options rather than dimensioning them. It carries no bill of materials and no build sequence, and it is written for an oceanic, clay-soil climate (Normandy, France). Regulatory notes are indicative and need confirming locally.
