The PV performance ratio depends entirely on pyranometer accuracy. Learn how the IEC 61724-1 formula works, why sensor class matters, and how to configure your monitoring for reliable PR....
Thermopile vs silicon pyranometer: two technologies with different accuracy, spectral range, and cost. Learn which sensor fits utility-scale PV, research stations, or rooftop projects....
The ISO 9060 classification defines how pyranometers are graded for accuracy and stability. Learn what changed in the 2018 update and how to match the standard to your project....
The pyranometer class you choose determines data accuracy, IEC 61724-1 compliance, and total project cost. Learn when Class A, B, or C fits your solar or research site....

The “Copy-Paste” Standard If you look at the technical specifications for any utility-scale solar project built in the last five years, you will find the same phrase pasted into almost...

The Sensor is Only the Messenger In our previous discussions, we established why hardware matters—why a fast-response pyranometer like the MS-80SH is critical for capturing the reality of solar irradiance....

EKO Instruments at SNEC 2026 – Shanghai June 3–5, 2026 National Exhibition and Convention Center (Shanghai) No. 333 Songze Avenue, Shanghai Booth: Hall 5.1 – A103 EKO Instruments will participate...

Introduction: The Era of High-Frequency Solar The solar industry has evolved. Fifteen years ago, hourly averages of irradiance were sufficient for simple grid-tied systems. Today, we are operating multi-megawatt utility-scale...
