Instrumentation for solar cooker measurements

Instrumentation for solar cooker measurements

TR-07
Challenges in measuring cooking vessel internal temperatures
A review of devices used in an attempt to measure pot internal temperatures while avoiding excess heat loss due to lid gaps.

TR-09.1
A system for standard power measurements of solar cookers
This report documents instrumentation requirements, selected products and preliminary measurements made in compliance with this standard. Heating tests of several solar cookers were conducted to establish repeatability of temperature measurements. Sources of variation were identified and mitigation strategies were developed. This experience will be useful in continuing work aimed at refining a protocol for the ISO standard and for constructing automated systems for solar cooker testing.

TR-31
Measuring Solar Irradiance with a Sun Tracker
The ISO-19867-1 standard for solar cooker power measurements specifies that available solar energy shall be measured in the plane perpendicular to direct beam radiation.” This requires pointing the pyranometer toward the Sun during the measurements. This Technical Report describes a sun tracker system driven by a Arduino servo controller to provide tracking.
