38th European Photovoltaic Solar Energy Conference and Exhibition; 1278-1283, The photovoltaic sector is still relatively young in the world and in the Region of Brussels, where most installations are barely ten years old or less. The goal of this study is to provide an overall picture of the state of the art of the photovoltaic park in the Brussels Region. It includes an assessment of the installed equipment, the price of the installations and their performance. More than 8000 PV installations distributed across the Brussels Region were considered in this study with data available up to the end of the year 2019, and including residential and commercial PV systems. The analysis of installation prices highlights the downward trend in prices which continues in 2019 with a reduction ranging from 5% for large systems to 16% for small residential systems compared to 2018. Since 2013, the average decrease in the different installed power categories is almost 40%. The solar resource in Brussels has gradually increased over the last four decades, with an average annual horizontal global solar irradiation over the last forty years of about 1000 kWh/m2. In the last ten years, the average value is estimated at 1078 kWh/m2, about 8% above the average of the last four decades. A historical maximum was recorded in 2018, with 1172 kWh/m2, which is about 18% higher than the average of the last four decades. The median energy yield of PV installations in the Brussels Region over the last decade was around 850 kWh/kWp. The median Performance Ratio of the PV installations in Brussels Region during the last decade was about 65%, which can be considered as a typical and representative value of the PV park. In comparison, typical Performance Ratios in Europe are in the range of 70-80%. This study has also found a correlation between the performance of the installations and certain key parameters such as the installed peak power, the year of commissioning, the brand of photovoltaic panels, the power category or the type of owner of the installation. Comparisons between module brands have also shown that there is no clear correlation between the geographic origin of a module brand and its performance.

32nd European Photovoltaic Solar Energy Conference and Exhibition; 2874-2878, This snapshot report gives information on the development of PV power applications in the PVPS member and non-member countries and is largely based on the information provided by the24IEA PVPS countries plus the European Union through its European Commission. The report includes information on national market developments and comments about the most important changes and trends in PV support policies at the end of the former year, in this case 2015.The International Energy Agency –Photovoltaic Power System Programme (IEA PVPS)’s Task 1 is responsible for strategy and outreach within the IEA PVPS program. This includes market and industry analysis. A key deliverable of Task 1 is the annual Snapshot of Global PV Markets publication, together with the TRENDS IN PV APPLICATIONS.

37th European Photovoltaic Solar Energy Conference and Exhibition; 2005-2009, Electricity markets in Europe are changing in response to the implications of the ongoing energy transition from centralized to decentralized and renewable energy supply. The European Commission has put focus on enlarging the role of prosumers, i.e. consumers that also generate electricity using photovoltaic systems. In response to that, we have investigated innovative self-consumption and aggregation concepts and business models for prosumers that will help integrating sustainable and competitive electricity from PV in the electricity system. We here report on the effect of prosumerism on electricity costs and greenhouse gas emission reduction in eight different countries: Austria, Belgium, France, Germany, Italy, the Netherlands, Portugal and Spain. Next, the implications for changes in the electricity grid have been discussed with relevant stakeholders, including distribution grid operators. Recommendations and policy advise to EU and member states are derived and presented here.
