Where comes the sun we reach: Pure Competence and mobility

The technical management of photovoltaic plants cannot be carried out effectively without a deep understanding of the technology and the ability to translate this expertise into operational tools to use in the field.

VWith extremely pragmatic approach, we have developed methodologies and technologies that allow us to perform specialized tests directly on site - with accuracy and quality comparable to laboratory equipment - in order to reduce costs, minimize downtime and stimulate a very effective interactive diagnostic system.

We have the know-how and a technical structure able to perform activities also on massive number of components such as verification of serial defects of the photovoltaic modules, verification of anomalies or malfunctions of the system resulting from improper installation and / or improper maintenance of components, extraordinary events impact assessment (hail, excessive snow loads, landslides, floods, etc ...) or resulting from accidental mechanical stress such as inappropriate hadling of components during attempted theft.

 
ON-SITE: FLASH TEST & ELETTRO-LUMINESCENZA
ON-SITE: FLASH TEST & ELECTRO-LUMINESCENCE
We can perform flash tests directly on site with the Mobile Laboratory or record high-quality images in electro-luminescence with the Portable EL units that allows to work in daylight without the need to dismount and disconnect the photovoltaic modules.
ON-SITE: INDAGINE TERMOGRAFICA
ON-SITE: TEMOGRAFICAL SURVEY
Thermal imaging is performed with high resolution FLIR thermal cameras. Our analysis program allows in first step to identify strings or individual modules with abnormal overheating and in a second step to inspect the single modules in detail to identify the specific defect, map the defect distribution on site and identify actions to be taken
ON-SITE: MISURE DI POTENZA
ON-SITE: POWER MEASUREMENTS
The measurement of the characteristic IV curve, instantly correlating the power measurements and environmental data at standard test conditions, allows you to check deviations from the theoretical power and verify the impact of any defects of the photovoltaic modules or malfunction at string level.
