Solar cooking:

• No pollution

• No deforestation

But:

• Outdoor cooking is not ideal

• Electrification is coming!

Why PV?

Design Main issues

PHOTOVOLTAIC SOLAR COOKER WITH NO BATTERIES USING ADVANCED ELECTRONICS

PV panels offer:

• Possibility of transferring electricity to an indoor kitchen.

• Lower efficiency than “thermal” cookers ~15% → high efficiency electric cooker.

PV panels need:

• A controller for power maximization.

• Batteries for the functioning of the commercial controllers (expensive and polluting)

Design:

• A controller circuit of high efficiency, low cost, and simple.

• A modified commercial electronic cooking utensil

CONCLUSIONS

• Electronic utensil modified for high efficiency PV cooking.

• Low temperature cooking is possible (tender boiling).

• Low cost ~ 300 € off-the shelf in Madrid.

• Robust design.

• Inner heat dissipation allows high efficiency.

• Insulation optimizes heat retention.

• Theoretical calculations and experimental validation.

Further work

• Pre-commercial prototype development

• Laboratory testing under realistic conditions (day and year-round)

• Testing at field conditions, user experience

• Low temperature cooking experience by users

• Electrification user experience

• Possible “commercialization”
