Abstract
In this paper, we undertake a study to investigate the performance of hybrid photovoltaic thermal air collector systems through energy and exergy efficiencies and improvement potential factors and compare them for practical purposes. This will help identify the irreversibilities (exergy destructions) for performance improvement purposes. A case study is presented to highlight the importance of the efficiency modelings and compare them using some actual data. It is also aimed to find if there is room for improvement. It is found that the energy efficiency varies between 33 and 45% where as the variation in the exergy efficiency is from 11 to 16%, respectively. There is obviously a large scope for improvement in the existing system as about 11–16% of the exergy from the solar radiation is used.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
