What is the Di-LOG SL104 Solar Irradiance Survey Meter?
The SL104 is a professional solar survey meter designed for UK electricians and solar installers. It measures solar irradiance, panel temperature, roof pitch and compass direction, helping you optimise PV and thermal installations for maximum efficiency and compliance with IEC 62446-1 standards.
How Does the SL104 Stand Out in Everyday Use?
With built-in sensors and an external temperature probe, the SL104 provides accurate real-time data for pre-installation surveys, system alignment and maintenance checks. Its integrated inclinometer and magnetometer make roof pitch and array direction measurements quick and precise.
