, is a manufacturer of solar test and measurement equipment and developer of solar design software. It was founded in 2005 and is best known for its shade measurement tool, the SunEye, and its I-V curve tracer, the PV Analyzer. The award-winning SunEye shade tool is used primarily by residential solar installers. It tells the user when and where shadows will fall so that solar modules can be placed to maximize energy harvest. The PV Analyzer is an I-V curve tracer. It is used for commissioning and troubleshooting commercial and utility scale

. It captures an image of the sky including the horizon, superimposes the sunpaths on top of the image, and calculates the solar access for that location. The PV Designer layout and simulation software product was first introduced in 2009 at Solar Power International. The software enables the user to layout PV modules on a roof virtually and simulate the energy production. The PV Analyzer I-V curve tracer (“PVA-600”) was introduced in 2010 and could measure strings up to 600 volts and 20 amps. The PVA-1000, introduced in 2013, added 1000 volt, 30 amp capability as well as the SolSensor wireless PV reference which measures the
