About SCI's testing process

Responding to requests from cooks, agencies, and manufacturers, SCI created an objective, scientific process to evaluate solar cookers: the Performance Evaluation Process (PEP). SCI objectively and scientifically evaluates how a solar cooker performs.  Solar cooks and purchasing agencies around the world need these valuable performance metrics to select the solar cooker that best fits the need.

SCI’s evaluation is:


SCI promotes all solar cooker designs that are:

  • High-performing and durable

  • Proven by testing according to the objective SCI performance evaluation process (PEP)


SCI is a solar cooker testing center registered with the
Global Alliance for Clean Cookstoves.

SCI has testing centers in Lalitpur, Nepal; New York, USA; California, USA; and Nairobi, Kenya.
