Solar Irradiance Meter
Product Code : SCL-PLE-11858
The JLab India Solar Irradiance Meter (Pyranometer) is a precision handheld instrument engineered for the empirical measurement of solar power density. This device allows students and engineers to quantify the amount of solar radiation reaching a specific surface area, typically measured in Watts per square meter (W/m2). It is an indispensable tool for University Renewable Energy labs to determine the efficiency of solar panels, perform site surveys, and study the atmospheric attenuation of sunlight.

Key Pedagogical Outcomes (Bloom’s Taxonomy Alignment)
- Environmental Interface: Facilitates student understanding of "Insolation" and how solar energy varies by geography, time of day, and weather conditions.
- Efficiency Quantification: Enables the physical calculation of Solar Panel Efficiency; learners apply the meter to find the available solar power (Pin) and compare it with the panel's electrical output (Pout).
- Atmospheric Analysis: Supports the analysis of "Optical Depth"; students evaluate how cloud cover, humidity, and air pollution attenuate the solar energy reaching the Earth's surface.
- Site Evaluation: Allows students to evaluate and identify the "Global Horizontal Irradiance" (GHI) and "Direct Normal Irradiance" (DNI) to determine the optimal placement for solar arrays.
International Logistics & Compliance
JLab India ensures comprehensive OEM readiness for global institutional procurement:
- Packaging: Export-grade protective carrying case. The sensitive silicon sensor is protected by a dedicated cap and nested in high-density anti-shock foam to maintain calibration integrity during transit.
- Documentation: Includes Manufacturer’s Authorization Form (MAF), Certificate of Conformance (CoC), and a factory calibration certificate traceable to international standards.
- Durability: Ruggedized handheld design featuring UV-resistant housing and a long-life battery system, ensuring reliable field use for environmental data logging.
Direct OEM Sourcing Advantages
Procuring the JLab India Solar Irradiance Meter directly ensures vertical manufacturing control:
- Cosine-Corrected Sensing: Our meters are engineered with a diffuser that ensures accurate readings even when the sun is at a low angle (non-perpendicular), which is critical for all-day data collection.
- Temperature Stability: Direct oversight of the sensor circuitry ensures minimal thermal drift, meaning the meter stays accurate even when the device itself heats up under direct sunlight.
- Direct Factory Spares Availability: Guaranteed availability of replacement sensors, battery doors, and protective cases to maximize the long-term ROI of the field equipment.
- Quality Assurance: Every unit is calibrated against a laboratory-standard pyranometer to ensure that students are working with data that reflects professional-grade meteorological accuracy.
