A heavily insulated cooking box (tile/cork/mortar heat store) heated by a self-made electric resistance element run directly off PV. Unlike the reflective solar cooker, it converts solar electricity to heat and retains it, so cooking does not need direct sun on the food and continues on stored heat. Battery-free; pairs with direct-solar supply. DIY build manual documented step by step.
Note: Cost, carbon and footprint are rated against the other options for this same need, not in absolute terms.
None (pairs with a PV array).
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.
