Building a solar dryer starts with site selection, which determines the entire project’s success. Choose level ground with full sun exposure throughout the day and protection from strong winds. Avoid areas that flood during rainy seasons or where large trees might create shade. Access to water for cleaning and borehole drilling services might be important for larger operations.

Foundation work doesn’t need to be complex but must be solid. A simple concrete foundation or even well-leveled stone foundation works for most designs. The foundation should extend slightly beyond the frame to provide stability and prevent water from pooling around the structure. Proper drainage around the foundation prevents moisture problems.

Frame construction requires basic carpentry or metalworking skills. Many farmers hire local artisans who can work with provided plans and specifications. The frame needs to be strong enough to support the cover material in windy conditions while providing anchor points for drying racks. Corner bracing prevents the structure from shifting during storms.

Cover installation requires careful attention to sealing and ventilation. The cover material must be stretched tight to prevent flapping in wind while allowing for thermal expansion. Proper sealing at joints prevents rain entry while maintaining designed ventilation openings. Some farmers add storm panels that can be installed during severe weather.

Interior setup involves installing drying racks, ventilation controls, and monitoring equipment if desired. Racks need to be removable for cleaning and adjustable for different crop types. Simple thermometers help monitor internal conditions, though expensive monitoring equipment isn’t necessary for basic operations.
