Photovoltaic cooking designs offer another approach to harvesting the sun to cook food. Instead of solely relying on the sun's direct radiation to cook, these systems use photovoltaic cells to provide power to an electric induction cooktop. Although the induction heating elements use relatively little electricity, their efficiency is greatly increased when combined with a solar thermal cooker.

Evacuated tube solar cooker designs provide a platform well suited to this hybrid approach. With the availability of an chargeable battery, this type of cooker makes cooking after sunset or in the early morning possible.

  • NEW: August 2019: Cooking with PV and phase change materials - Pete Schwartz explains how his research group at Cal Poly, USA is using a relatively low power photovoltaic panel to produce electricity to run an induction heating element, which runs through a phase changing heat storage medium. The medium melts at 120 °C (248 °F) during exposure throughout the day. In the evening the medium is hot enough to cook a meal fairly quickly without the sun, stored battery power, or further inout from the induction heating element.

SolaCooka

SolaCooka

The SolaCooka stores energy in the ground in a phase change material. The concept has been tested with success, and now there is an effort to get it to mass production in India and similar countries where self-install kits are to be distributed, some for a price and some for free. Quotes have been obtained for 80W PV solar panels, which can be built for USD 10, making this practical and affordable. There is a plan to employ people living in the slums to put together the kits for people to install.

Electric cooking is convenient and widely adopted globally, while photovoltaic cells are ideal for small-scale electricity generation in many areas. Assuming the continuing decrease in photovoltaic prices, when might we expect PV solar cooking systems to be cost competitive?
