Advanced Solar Irradiance Survey Meter with built-in Temperature & Compass Inclinometer
The Di-LOG SL104 Solar Irradiance Survey Meter is a versatile tool designed to assist professionals in the solar industry including Solar PV and Solar Thermal. Whether you’re conducting a pre-installation survey, installing a new system, or performing routine maintenance, the SL104 provides the essential measurements needed to ensure optimal performance.
This compact and user-friendly device measures solar irradiance, a critical factor in determining a system’s potential output. It also accurately measures the temperature of solar panels, both on the surface and underneath, using either the built-in sensor or an external probe. Additionally, the SL104 incorporates a precise magnetometer to measure the array or roof pitch angle and magnetic direction, aligning with the industry standards defined in IEC 62446-1.
With the SL104 Solar Irradiance Survey Meter, solar professionals can streamline their workflow, make informed decisions, and deliver high-quality installations and maintenance services.
Key Features:
- Solar Irradiance Measurement to 1400 W/m²: Indicating in real-time how much solar power is available to convert into electricity.
- Inbuilt Cell Temperature Sensor: The inbuilt surface probe located on the base of the SL104 offers a quick indication of the surface cell temperature.
- External Cell Temperature Probe: The attachable external probe connects directly to the SL104 and offers a quick indication of the underside cell temperature of the panel.
- Inbuilt Magnetometer Compass: The inbuilt compass will enable you to determine the roof direction to gain an accurate array direction.
- Roof Pitch Inclinometer: The integrated inclinometer will assist in determining an accurate pitch of the roof angle the array is intended to be mounted to help calculate the efficiency of the array.
