Project (Task) Conclusions
Solar crop drying can be feasible in many large scale applications.
Solarwall panels are capable of supplying heat to drying process as predicted in the feasibility studies
BUT…..
Weather and cost data are often difficult to obtain for accurate feasibility studies. - Recommend on site data collection for year prior to design
Many existing crop drying facilities are designed, built and operated inefficiently - Before installing a solar drying system, experts should take the time to fully understand all aspects of the candidate facility. This time should include at least one drying season
Facility should be upgraded and measures taken to reduce energy waste before solar -
Commissioning may take a full drying season
Engage a local expert
Design manual should be prepared in conjunction with on site staff
On site staff must be made comfortable with automatic operation
Monitoring should be used to help refine operation Commit the necessary resources Consider clustering projects
