Abstract
Effectiveness of solar tent dryers in agricultural products has been well documented, but this information may not be generalised for use of solar dryers in all agricultural commodities and for all sizes of solar dryers. As such, we evaluated the economic viability of large capital intensive solar dryer that has been designed to dry small fish species on commercial basis on Lake Malawi. A probabilistic net present value (NPV) analysis was applied to a 15-m-long by 8-m-wide solar tent dryer which costs MK1,513,850 (US$2100) to construct and has a maximum carrying capacity 850 kg of fresh fish. The results show that the base NPV of this solar tent dryer is MWK5, 838,482.11 (US$11,762). When risk and uncertainty are considered, the probabilistic NPV becomes MWK12, 268,503 (US$24,716). The probability of obtaining a positive NPV was 58%, and we found that NPV is highly sensitive to total revenue and total cost but not to their components. We conclude that investments in large solar tent dryers are economically viable and that viability would be enhanced through access to formal fish markets where prices are stable and high.

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
