These small scale photovoltaic cooking systems offer another approach to harvesting the sun to cook food. Instead of solely relying on the sun's direct radiation to cook, they use photovoltaic cells to create electricity to typically provide power to electric induction cooktops or electric pressure cookers. The energy can be stored in batteries for use when needed.
Research has also been undertaken to test the cooking potential of a simplified system incorporating an array of diodes connected directly to photovoltaic panels.
Although the induction heating elements efficiently use electricity to directly heat ferrous cooking pots, their efficiency can be increased when combined with a well-insulated solar thermal cooker, or with using insulated cook pots.
Evacuated tube solar cooker designs provide a platform well suited to this hybrid approach. With the availability of an chargeable battery or phase-change thermal storage, this type of cooker makes cooking possible after sunset or in the early morning.

August 2024: Hybrid PV solar box oven: - Stan Wells continues to explore various ways of making solar cookers more powerful and efficient. He is testing adding PV powered direct resistance heating elements to his solar box cooker design. At the time of the photo, in somewhat cloudy conditions, he reports that the cooker was at 166 °C (331 °F) compared to its twin at just over 94 °C (201 °F) with solar thermal only. The solar electric heat can be controlled by the digital thermostat on the tracker or the mechanical thermostat on the cooker. When the cooker reaches the desired temperature the electric heaters switch off. They might stay off all day until the temperature drops below the setting. If we open the door to look at the food and lose some heat, the electric pads will come on for a short time to help restore the desired temperature.
September 2023: ECOCA pilot stove program: - Mercy Corps in partnership with the Danish company Pesitho, has initiated a pilot program at the Bidibidi Refugee Camp in Uganda to make PV-powered ECOCA induction stoves available to residents of the camp. The program will provide a pay-as-you-cook method of payment for residents. As in other refugee camps, the women are usually the most vulnerable, having to go the edges of the camp and beyond to gather what little firewood is available for cooking. This leaves them open to possibly becoming victims of violence. The new stoves will help relieve that stress. When fully charged, the ECOCA has enough energy to cook three meals a day. The need for time-intensive firewood gathering disappears, as does the carcinogenic smoke and pollution produced by wood fires. Women have more time to attend community meetings, socialize with friends, care for their families, or invest in income-generating opportunities. Read more...

April 2021: Using nichrome wire as an assist to solar cooking, and as stand-alone cooker with (PV charged) batteries - Craig Bergland, a solar inventor living in Nevada, USA, has been experimenting heating nichrome wire to assist in raising the cooking temperature within solar box ovens, seeing raises of 27–38 °C (81–100 °F). He has managed to do this with relatively low cost components. Read about his results here on his personal page.
February 2021: Cooking directly from PV panel to heating element: - Bernhard Müller has shared his recent experiences. He initially used a 50w heating pad connected directly to a 50W PV panel, but discovered using a 40w pad was more efficient. He was able to have the heating pad reach 120 °C (248 °F). He recommends this approach can be used for most cooking, except for baking and frying. It is important to use a well-insulated cooking chamber and limit the length of the connecting cables, as cable resistance will limit output.

February 2021: Jane and Seggy Segaran have been experimenting cooking with a 60 watt heating element powered by photovoltaic panels. They first charge a battery with the panels. This makes it possible to provide a more concentrated amount of power to the heating element than can be achieved directly from the PV panels. The food is cooked within a highly insulated assembly. They have found "A 100 W solar panel can provide a peak power of 70 to 80 Watts. If it is in a fixed orientation (and does not track the sun) then my estimate was 50 watts average power over a 6 hour period. 50 watts means a current of around 4 Amps going into a 12 V battery. So to fully charge a 75 Ah battery is going to take around 20 hours – or just over 3 days. So 3 days of charging will provide 10 hours of cooking." Read more...
Comparative simplicity of a diode vs an induction cooking system, ScienceDirect.com. Vol 4, 2019
March 2020: Research begins using thermal diode arrays for cooking - Cooking powered by photovoltaic panels appears to be developing rapidly. Early research involved cooking directly with induction heating elements. However the direct thermal output was low temperature, and researchers concluded induction systems worked more efficiently when included with battery storage, or a phase-change medium. The phase-change medium would be heated throughout the day, and be able to give back the heat at a higher rate to the induction element for cooking later in the day (See August 2019 news item). Recent development with incorporating thermal diodes arrays shows the possibility of using a simpler and less expensive system to generate heat for cooking. They do not require 12v charge controllers, voltage converter, batteries, and inverters of traditional PV systems, but they do not intrinsically have energy storage capabilities. They require a thermostatic switch to interrupt the circuit above a predetermined temperature. This research is in its infancy, and more detailed information can be found in: Hot diodes!: Dirt cheap cooking and electricity for the global poor? - Volume 4, 2019, 100044 ScienceDirect (See also the May 2020 video below produced by Pete Schwartz and his team cooking with this method in Ghana.)
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 in place of a battery - 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 input from the induction heating element.

Insulated Solar Electric Cooking with Thermal Storage, EWB Sweden, Pete Schwartz, Cal Poly Physics-2
Pete Schwartz presents his team's latest findings, as they develop different approaches to insulated solar electric cooking. He predicts an eventual decline in the use of phase change materials (PCMs) to retain the heat for cooking, as batteries become a more efficient and less expensive way to store energy. This may happen in the next ten years. In the meantime, a solid block of aluminum is showing promise as a simpler way to store heat compared with PCMs.
