About This Product
In renewable energy practicals students use the meter to measure how much sunlight reaches a solar panel, then compare it with the panel’s electrical output to work out efficiency. Tilting the sensor shows how the angle to the sun changes the irradiance received. Enquiries from Estonia, Indonesia, New Zealand, Kyrgyzstan, Burkina Faso and Equatorial Guinea for the Solar Irradiance Meter receive an export quotation.
