Solar Fan Model
Product Code : SCL-PLE-11857
The StemAids Solar Fan Model is a fundamental energy conversion apparatus engineered to demonstrate the direct transformation of solar radiation into mechanical work. This unit utilizes a high-sensitivity photovoltaic (PV) cell to power a low-inertia DC motor, driving a fan blade assembly. Manufactured to ISO 9001:2015 standards, it is an essential instructional tool for primary and secondary science laboratories to visualize the "Sun-to-Wind" energy path and the impact of irradiance on electrical current.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Energy Conversion Interface: Facilitates student understanding of the direct conversion of Radiant (Solar) energy into Kinetic (Mechanical) energy.
- Irradiance Quantification: Enables the physical study of light intensity; learners apply varying light distances and calculate the change in fan RPM (revolutions per minute).
- Efficiency Analysis: Supports the analysis of the "Angle of Incidence"; students evaluate how tilting the solar panel away from the light source significantly reduces motor speed.
- Circuit Continuity Evaluation: Allows students to evaluate the relationship between open-circuit voltage (Voc) and short-circuit current (Isc) by using the on-board test points during motor operation.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade, reinforced packaging. The propeller blades and motor assembly are nested in vibration-dampening foam to prevent shaft misalignment during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a student-friendly "Green Energy" experiment worksheet.
- Durability: Tropicalized design featuring UV-stabilized plastics and anti-corrosive motor contacts, ensuring the model remains functional after repeated exposure to direct sunlight.
Direct OEM Sourcing Advantages
Procuring the StemAids Solar Fan Model directly ensures vertical manufacturing control:
- Matched Power Profile: We utilize custom-wound motors with ultra-low startup currents, ensuring the fan rotates even under diffused or indoor laboratory lighting.
- Integrated Safety: Direct oversight ensures the fan blades are manufactured from soft, lightweight materials to ensure student safety during high-speed rotation demonstrations.
- Direct Factory Spares Availability: Guaranteed availability of replacement solar cells, propeller blades, and DC motors to maximize the long-term ROI of the science kit.
- Precision Labeling: The base features a high-clarity schematic, helping students identify the Anode (+) and Cathode (-) paths from the panel to the load.
