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.

• November 2019: Electric cooking starts to simmer in rural India - Following the success of the Saubhagya initiative and its announcement of 100 per cent rural household electrification, efficiency gains and cost reductions in solar panels and batteries are opening up a new market that has the potential to avoid using any solid or fossil fuel, with solar-powered electric cooking or e-cooking using pressure and rice cookers and induction stoves gaining traction. The winner of the 2017 challenge, IIT Bombay, has since conducted a project to convert the entire village of Bancha in Madhya Pradesh, India to solar panels and induction cookstoves instead of wood-burning or LPG stoves. With Rs 8.5 million provided by ONGC, all the 75 houses in Bancha now rely on solar-powered electric stoves to meet their cooking needs. Besides reducing air pollution, villagers no longer have to collect firewood from nearby forests, saving time and effort. More information...

• 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.

• June 2018: PV supplements solar cooking - Seggy T Segaran has experimented with adding more cooking power to a solar box cooker, provided by a heating pad located inside the cooker. It is powered by the nearby 100w photovoltaic panel. He reports the heating pad on its own put around 35 watts of power into the solar cooker. When placed in the sun, the cooker ran at around 70 watts of combined solar and electric power.

• March 2016: Antonia Lecouna Neumann reports: "We use erythritol as heat storage material, cheap, durable, edible and has a melting heat similar to ice. We found it superior to other alternatives although long term durability is still an issue." Read more...
