The PVET® service allows optimizing the long-term production and operating costs of photovoltaic power plants to maximize their economic return. This service is based on a continuous evaluation of the operation of the photovoltaic plants of the client with a detailed supervision of its operation through the PVET calculation engine.

The PVET engine is a Big Data system aimed at analyzing data from photovoltaic plants. Its objective is to analyze the operation of these plants by extracting data related to their operation and providing detailed information on their evolution over time, their status in real time, fault diagnosis and preventive analysis. In addition, analyzes are not limited to individual plants, but they study photovoltaic assets as a whole, achieving higher levels of optimization. This new approach allows our clients to have a greater strategic vision of the assets and to be able to manage their operation in a more precise way. For all these reasons, the PVET engine is a powerful analysis tool for the photovoltaic sector at engineering and O&M level, both in existing plants and for portfolios of growing assets.

The PVET service is delivered through its own management platform adapted to new technologies. This platform adds new functionalities to the PVET service in addition to those focused on the data analysis.
