Abstract
Many public electric utilities in Africa are capital constrained. In this paper, an economic analysis is carried out to investigate the efficiency of investing in solar photovoltaic power plants, as an option for on-grid power generation. A comparison is made in terms of the economic net present value as well as greenhouse gases savings if the same amount were invested in a combined cycle thermal power generation. The results show that economic net present value is negative for solar photovoltaic plant, whereas it is a large positive value for the combined cycle plant. In addition, the combined cycle plant would be two times as effective in reducing greenhouse gases as the same value of investment in solar photovoltaic plant. Even with solar investment costs falling, it will take 9–18 years of continuous decline before solar generation technology will become cost-effective for most of Africa.

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
