Solar panel will charge a 12V battery. The 12V dc from the battery will be converted to high frequency ac. This ac will be fed to a coil on a magnetic core. The rsulting alternating flux will create Eddy current and Hysteresis losses which will heat the nagnetic core. Cooking pot placed on the magnetic core will do the cooking.
Build the battery charger from the solar panel; use the Arduino to program the gate signals of MOSFETS to generate high frequency ac which will be fed to the magnetic coil. Number of turns of the magnetic coil to be calculated and shape of the magnetic core has to be designed.
The heating by Eddy current and Hysteresis losses is dependent on frequency of ac and the magnitude of the flux. The heat generated should be such as to bring one litre of water to boiling from ambient temperature in ten minutes
