Comparative analysis of the conversion performance of a grid-connectedphotovoltaic system
Bibliographic record
Abstract
A performance study of a photovoltaic system installed in an eco-house on the campus of the University of Calgary in Canada is presented. The panels of the photovoltaic array installed on the roof have different azimuth and tilt angles, therefore, the solar energy incident on them is different. The effects of orientation on the efficiency of electrical energy production in individual photovoltaic modules are analyzed. The conversion efficiency is determined by means of measurements of the energy produced by the modules, supported by the RETScreen software, but also independently, it is calculated using the radiation data from the university weather station (WRS). These results are compared with those of a previous study, carried out with PVSyst, where the orientation angles of the system are simplified. Average results of energy produced, and efficiency are shown. It is observed that the efficiencies from the simulations are very similar, although of lower value. The results obtained with WRS are considered more realistic and of greater magnitude.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
