UK: 0% feed-in limit

The attractive feed-in prices paid in the UK have given rise to a massive growth of PV power plant capacity. Grid operators therefore need to limit feed-in from PV systems.

The WEB’log data loggers of the Industrial Line already have a function to increase yield by considering on-site energy consumption: Intelligent Power Limit. A meter at the grid connection point continuously measures power supplied from or fed into the grid. The WEB'log unit communicates continuously with this meter, and dynamically controls the inverter and hence the amount of energy supplied depending on the recorded grid parameters. If the grid operator demands that no current may be fed-in at any time, then the meteocontrol system ensures 0% feed-in.

Discontinuation

• Irradiance sensor SI-12-TC-LC: Item number 423.014
• Irradiance sensor SI-RS485-TC-T: Item number 423.015

Since 10/31/14 the irradiation sensor SI-12-TC-LC has no longer been listed in our product range. As an alternative we can offer you the irradiation sensor SI-12TC (0-10V): Item number 423.000. As a result of this change, the WEB'log Home Package (WEB'log Comfort + irradiation sensor SI-12-TC-LC) is no longer available. The data logger WEB'log Comfort will remain available.

To replace the irradiation sensor SI-RS485-TC-T we offer a new version with extended temperature ranges, the radiation sensor SI-RS485-TC-T V2: Item number 421.016.

safer'Sun Public now in Dutch

The new version of the meteocontrol safer´Sun Public monitoring portal now supports a further language, adding Dutch to its list of supported languages: German, English, Spanish, Italian, French, Japanese and Chinese.

New menu structure for Modbus sensors and Modbus meters

Until now visualization options for Modbus sensors could be found under the heading “Weather Station” and Modbus counters under “Power Quality Analyzer”.

Now you will find individual menu items on the portal page for Modbus sensors (e.g. light, temperature) and Modbus meters (formerly Power Quality Analyzer). The modified menu structure is activated automatically when new PV systems are set up, or this can be done manually by selecting Administration → Graphic selection.

Yield reports by meteocontrol have for many years served as a reliable basis for assessing PV projects. Access to highly accurate weather data make compiling realistic forecasts of expected yields possible. Our meteorological data is updated regularly according to state-of-the-art scientific findings, which in the recent years has led to a trend to forecast higher specific yields while incorporating these new data sets for the European region.

The continual validation carried out by meteocontrol on a data base of over 35,000 monitored PV installations (total capacity: 9.2 GWp) has an even more significant effect on the precision of our yield calculations. These results incorporate the latest findings from climate research as well as the extensive know-how gleaned from meteocontrol’s manifold and diverse projects all over the world. For example, they take into account effects such as specific contaminants in desert regions, snow conditions in Germany, etc., thus providing realistic assumptions for evaluating performance ratios. Even for on-site energy consumption there are now often extremely accurate loss assessments.
