Maintaining your sensor or instrument
What is the recalibration interval of a solar sensor?
The sensitivity of any solar sensor deviates over time when exposed to solar radiation. Most sensors have a recommended 2-year recalibration interval.
However, thanks to superior design, build quality and stability, many of our class and industry-leading sensors, including the Class A MS-80 and MS-80S Pyranometers, and MS-57 Phyrheliometer, have a 5-year recommended recalibration interval.
Your sensor should have come boxed with a calibration certificate showing the date of the original calibration and recommended recalibration interval. But, if your sensor has been stored correctly, you can calculate the actual recalibration date, based on the recommendation, from the date of installation or first use.
The calibration is not altered when the product is not used.
EKO Instruments offers Pyranometer, Pyrheliometer & Viscometer recalibration from our accredited global calibration laboratory in Tokyo, Japan. Pyranometer recalibration is also available at our laboratory in the Netherlands.

Setting up your sensor or instrument
How does the intergrated sun-sensor help with setting up an STR sun tracker?
The sun sensor is a crucial component of our STR sun trackers, helping to ensure accurate tracking.
STR sun trackers follow the sun by calculating its position. The position of origin is determined by the orientation and levelling of the tracker. However, it can be difficult to find the perfect position of origin in practice. Consequently, misalignment of the tracker and all the solar sensors attached can occur despite the precise solar position calculation.
With STR sun trackers, the sun sensor is part of an active feedback system, compensating for any deviation from the ideal position of origin.
All STR sun-trackers are equipped with a standard sun sensor to guarantee high precision sun tracking without manual adjustment.

What is ISO 9060:2018 and what does it mean for my solar sensor?
ISO 9060:2018, introduced in 2018, is an international standard for solar sensors. It determines how sensors are ranked and categorised; re-defining and providing simpler, clearer, and more consistent standards across all kinds of sensor technologies compared to earlier standards.
Today, all EKO solar radiation sensors correspond to ISO 9060:2018.
