Big Solar Fan Model
Product Code : SCL-PLE-11814
The StemAids Big Solar Fan Model is a large-scale demonstrational workstation engineered for the empirical study of solar energy harvesting and mechanical work conversion. This high-visibility model utilizes an oversized photovoltaic (PV) panel to power a high-torque DC motor, driving a large fan assembly. Manufactured to ISO 9001:2015 standards, it is optimized for Secondary and Vocational education to quantify the relationship between light intensity (irradiance) and mechanical output (RPM) within renewable energy modules.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Energy Interface: Facilitates student visualization of the "Photon-to-Electron" transition, supporting Renewable Energy Module 101 by demonstrating the direct conversion of solar radiation into electrical current.
- Irradiance Quantification: Enables the physical study of efficiency; learners apply varying light distances or shading to observe the direct impact on the fan's rotational speed.
- Angle of Incidence Analysis: Supports the analysis of solar tracking; students vary the panel angle to evaluate the cosine law of illumination and its effect on peak power output.
- Sustainability Evaluation: Allows students to evaluate the viability of solar-thermal cooling systems, fostering a deeper understanding of carbon-neutral mechanical engineering solutions.
International Logistics & Compliance
StemAids ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade seaworthy crating (ISPM-15 compliant) featuring "Double-Cushion" foam to protect the glass-fronted solar panel and the delicate motor shaft from mechanical vibration during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a datasheet specifying the Open Circuit Voltage (Voc) and Short Circuit Current (Isc).
- Durability: Tropicalized design featuring weather-resistant wiring and UV-stabilized fan blades, ensuring the model does not degrade when used in direct outdoor sunlight.
Direct OEM Sourcing Advantages
Procuring the StemAids Big Solar Fan Model directly ensures vertical manufacturing control:
- Matched Power Profile: Every motor is specifically matched to the solar panel's peak power point (Pmax), ensuring the fan starts spinning even under moderate indoor laboratory lighting.
- Precision Blade Balancing: Direct oversight of the propeller molding process ensures vibration-free operation, which is critical for accurate RPM measurement and mechanical longevity.
- Direct Factory Spares Availability: Guaranteed availability of replacement PV modules, DC motors, and fan blades to maximize the long-term ROI of institutional laboratory assets.
- Manufacturing Control: Direct oversight of the electrical connections ensures ultra-low contact resistance, allowing students to measure the true efficiency of the photovoltaic cells without parasitic losses.
