Shade measurements in hard-to-reach places

In many situations, shade measurements are needed but you cannot get yourself into the right position. For example, roof access may be difficult or not allowed. Or a proposed solar structure is not yet built. Ladders and lifts can be expensive or dangerous, and calculations can be difficult and error-prone.

The new SunEye Extension Kit enables accurate measurements with a Solmetric SunEye™ 210 up to 5.4m (17.7 feet) above ground level. It consists of a telescoping extension pole with a plate at the top to hold a Solmetric SunEye 210 securely. The full assembly is lightweight, rugged, and non-conductive.


The Solmetric SunEye 210 is a handheld electronic instrument for measuring shade and evaluating a site for a solar energy system. When using the Extension Kit, SunEye measurements are captured by rotation of the pole combined with audio feedback from the SunEye. The SunEye will automatically correct the measurements for azimuth and tilt using inputs from the on-board sensors. For storage and transport the Extension Kit collapses to a length of 1.5 meters (4.9 feet).

Sierra was the first to introduce a combination volumetric vortex and multivariable mass flow meter in 1997. Today, Sierra's completely redesigned InnovaMass® iSeriesâ„¢ 240i/241i builds on two decades of success measuring five process variables for gas, liquid and steam with one connection. Now, with the latest hyper-fast microprocessors, robust software applications, field diagnostic and adjustment capability, and a new state-of-the-art flow calibration facility, Sierra's vortex iSeries delivers precision, performance, and application flexibility never before possible.
