Cleaning solar panels: an evolution
The craze for solar panels begins in the 1980s. Following the oil shocks, electricity produced by ‘alternative’ sources appears to be an effective long-term solution. The first MW of production at the world level is reached in 1999. The United States, a pioneer in the field to the point of owning 21% of the total… Read more »
One portal, many components
PES met up with Brigitte Beck, CEO at Solare Datensysteme GmbH. Their new portal, developed over 2 years, with input from customers, provides plant operators with an even faster and deeper fault analysis, saving considerable time and expenditure. They are at the cutting edge of digitalisation and that is where they aim to stay. ‘The… Read more »
The have-it-all synergy between monitoring & aerial data for solar PV
Every company that owns solar plants wants to generate the highest return. In order to achieve this, the system’s maintenance teams need to constantly ensure the optimal functioning of all system components, especially the panels and inverters. A solar monitoring system enables you to be informed of your PV system’s performance. The industry standard: solar… Read more »
It’s all in the vacuum
Jonas Dobner, Application and Project manager at Pfeiffer Vacuum dropped in on PES Solar. Needless to say, we were very interested to hear about their latest vacuum technology and solutions. These are already making an impact in the renewable energies segment and used in leak detection and various types of lithium batteries in the company… Read more »
Is knowledge really power?
Yes it is, if we take what we have learned from asset management in other industries and apply it to operational safety in battery energy storage systems. Utility-scale battery energy storage systems (BESS) are becoming a more common feature of the UK electricity network for the purpose of frequency regulation and balancing. There is also… Read more »

Here the workers are proud of their products and provide only the highest quality and efficiency to the… Read more »
Grid feed-in at high-voltage level: a case study
Grid integration is a key issue in the expansion of renewable energies throughout Europe. The requirements for power generation plants at all voltage levels have changed significantly with the pan-European harmonisation of grid connection requirements and the resulting adaptations to the national foundations. The aim of the EU regulation is to create a stable electricity… Read more »
Explaining PV plant monitoring to IEC 61724-1
Reliable measurement of solar irradiance, and other environmental parameters, is crucial to accurately calculating the performance ratio (PR) of a solar energy plant. IEC 61724, published in March 2017, is the latest and most comprehensive international standard to address these issues. But what does it mean? IEC 61274-1 Photovoltaic system performance – Part 1: Monitoring… Read more »
Combining highest throughput and precision in IV measurements of high-efficiency bifacial silicon solar cells
Abstract: we analyze available measurement time in a sun simulator in highest-throughput production of silicon solar cells. We explain how this time is distributed on the different measurements, which need to be performed to characterize a solar cell. For high-efficiency solar cells, we elaborate how it is possible to reduce the required measurement time to… Read more »
