Photovoltaic inverter data collection

How is PV system data collected?

The PV system data is collected when the installers apply to the grid operator for a grid connection. Registers developed in order to follow the financial incentives and especially the feed-in tariffs granted to PV systems normally collect DC power information (nominal power of PV modules under standard test conditions STC).

How does a data logger work in a photovoltaic system?

Operating large photovoltaic systems requires continuous monitoring and control at segment level. These tasks are performed by our data logger. It records all the relevant data on ambient conditions and the status of the inverter. This data is then transmitted to our superordinate portal.

What is a photovoltaic monitoring system?

Local and remote photovoltaic monitoring systems are primarily used to collect data about solar panels for the purpose of maintenance and repair. Additionally, monitoring systems are used to measure and analyze energy production performance data. Another objective is to minimize hazards to personal safety associated with periodic manual controls.

What are the characteristics of inverter data?

The inverter data contains characteristics such as active power, alternating current, alternating voltage, today’s generation, direct current voltage, direct current power, and reactive power with 1-min granularity for each day.

What parameters are required for a photovoltaic system?

For photovoltaics, there are also some specific parameters required (fixed, 1-axis or 2-axis; peak power, inverter power, and retribution obtained). Dynamic data (e.g. energy yield data) is not covered by the database.

Can a solar photovoltaic system generate AC power at 50°C?

Herein, we have successfully collected real-time data from both meteorological observations and the AC power generated by a solar photovoltaic (PV) system at a precise ambient temperature of 50°C in this study, which constitutes a landmark accomplishment in the field of solar energy research.
