Stan Wells

Stan Wells has been responsible for creating some of the most inventive tracking devices for individual solar cookers the community has seen. Built with ingenuity and a modest amount of equipment, he continues to raise the bar on what is possible.
He settled on forested property in northern , USA in the 90’s, with a tent, a battery, and a solar panel. He started exploring solar cooking with a Sun Flash parabolic solar cooker, purchased via mail-order catalog. It served he and his wife quite well for several years. Next to arrive was an All American Sun Oven. Generally happy with the cooker, he was not satisfied with the lack of adjustment in the tilting mechanism, and designed a new mechanism incorporating a lazy susan. Soon he was working on his first solar tracker.
He has constructed a number of prototypes, and found when you solve one problem, you often create another. For example, a wireless remote control was a fun feature that allowed to remotely drive the cooker back into the sun. But that required two motorized wheels up front and tracking motors are best if they are low geared. When your prospective meal becomes shaded, slow motors take way too long to relocate the cooker. So they wound up having to pick the whole thing up defeating the purpose of the remote control.

Since 2020, his solar trackers have had the ability to simultaneously follow the sun along both the vertical and horizontal axis, instead of simply rotating the cooker, which maximizes the amount of available solar gain. He credits his participation with the Solar Cookers World Network Facebook group, with helping to provide information and encouragement for his projects.

*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 compared to its twin at just over 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.
*May 2024: Stan Wells is employing a trio of solar cookers, all fitted with dual-axis trackers, to help prepare a solar feast. The cookers shown are a SUNplicity parabolic, All American Sun Oven box cooker, and a homemade box cooker. 
*November 2023: Stan relates: 'This is my most advanced cooker/tracker. Dual axis tracking with digital thermostat. The bung is super insulated so the tube cooks evenly throughout. The solar panel cube on the far end is the tracking sensor. The panels on the other end keep the 3s 18650 batteries charged. It rotates and tilts just slightly every few minutes controlled by the nearest star' He mentions the food shown below was cooked in 15 minutes. Impressive.
