About This Product
The sensor is placed in the same plane and orientation as the surface being assessed, kept clear of shadows from the body, tools or cables, and the value recorded with time, location, weather and angle once it settles. In the Properties of Matter listing it is the field instrument for solar radiation and renewable-energy lessons.
Frequently Asked Questions
Q1. Can it measure the electrical output of a solar panel? No. It measures incoming sunlight at a surface, not panel voltage, current or power.
Q2. How is a reading taken? Place the sensor in the same plane as the surface being assessed, keep it unshaded, let the reading stabilise and record it with the time, location, weather and angle.
