TIS PV1: Your Essential Solar Irradiance Meter

The TIS PV1 Solar Power Meter provides accurate measurements of solar power, making it an indispensable tool for solar professionals and energy auditors. Whether you're determining the optimal angle for solar panels, assessing the performance of solar window film, or simply measuring solar radiation, the TIS PV1 delivers clear, reliable results.

Key Measurement Applications

As outlined on the Test Instrument Solutions website and in the product manual, the TIS PV1 is perfect for a range of solar measurements:

• Solar Panel Optimisation: Determine the optimal incident angle to maximise energy capture from your PV panels.
• Solar Radiation Measurement: Quantify the amount of solar power reaching a specific location.
• Transmission Measurement: Easily assess the effectiveness of solar film on windows by comparing readings taken through the glass versus direct sunlight. This helps understand potential energy savings and the impact on different energy tariffs.
• Car Window Intensity: Measure light intensity through vehicle windows.

User-Friendly Features

Designed for convenience and accuracy:

• Selectable Units: Choose between W/m² (up to 1999) or BTU/(ft²*h) (up to 634).
• Clear Display: A 3 ¾ digit LCD provides easy-to-read measurements.
• Simple Operation: No complex adjustments needed; data is displayed clearly. The manual confirms its straightforward use.
• Data Hold: Freeze the current reading on the display for easy recording.
• Zero Function: Allows for zero adjustment for precise readings.
• Auto Ranging: Simplifies operation across its measurement range.
• Stable Readings: Provides consistent measurements suitable for long-term use, according to its features list.
