The IEA-PVPS Task 14, led by Austria as Operating Agent, promotes the use of grid connected PV as an important source in electric power systems on a high penetration level where additional efforts may be necessary to integrate the dispersed generators in an optimum manner. In a number of case studies from the participating countries, the challenges and approaches in the field of distribution networks, system management and power electronics components were shown in an international context. The result being elaborate reports with targeted recommendations and required measures to significantly increase the share of photovoltaics in electricity grids.
IEA PVPS Task 14: Solar PV in the 100% Renewable Energy Source based Power System (working period 2018 - 2022)
IEA PVPS Task 14 aims to enhance the international collaborative efforts defining the technical base for photovoltaic solar energy as a cornerstone in the future 100% renewable energy source based electric power system.
Building integrated Photovoltaics (BIPV) is one of the future markets for Photovoltaics which enables the combination of architecture and energy technology. The project focussed on further national research in the area of BIPV, which is to be raised to an international level.
The focal points of this Task are: Digitization of the BIPV planning processes (BIM), creation of a multifunctional evaluation matrix (ecological, economic, energetic, architectural); harmonization (construction, electrical engineering) of the pre-normative tests of BIPV elements as well as the creation of a practice-oriented guideline for the construction industry.
The IEA PVPS Task 17 focuses on the potential contributions of PV technologies to the transport sector as well as on the expected market potential of PV application in the transport sector.
This task, which is mandatory for all countries participating in the IEA-PVPS program, has been producing global reports on photovoltaic development since 1993. In addition, content-related priorities are set, or new topics and tasks are developed, which are then sent to the ExCo for decision-making. This gives Task 1 strategic importance for the overall IEA PVPS program.
Enhance the international collaborative efforts which facilitate the role of photovoltaic solar energy as a cornerstone in the transition to sustainable energy systems. The IEA PVPS programme aims to realise its mission through objectives related to reliable PV power system applications, contributing to sustainability in the energy system and a growing contribution to CO2 mitigation.
IEA SHC PVT Task 60: Applications of Photovoltaic/thermal (PVT) Systems and New Fields of Application and Examples of PVT
The international research collaboration IEA SHC Task 60 (Application of PVT Collectors) identified existing applications for PVT technologies and evaluated and highlighted potential system solutions where PVT technology has clear advantages over separate installation of PV modules and solar thermal collectors. In analogy, their advantages and current barriers for a broad market acceptance were highlighted.

The key accomplishments of the task are summarized in the following points: New material characterizing methods were investigated, a new standard for an improved DSC measurement method has been developed, a data base for PCM, TCM and sorption materials was developed and established, advances in the numerical modelling of materials, compact thermal storage systems were developed for different material applications, a tool for the economic evaluation of thermal energy storages has been developed. Also numerous joint R&D Projects and more than twenty publications arose from the IEA-SHC Task 42 networking activity.
The completed IEA SHC Task 48 focused on an enhanced quality improvement and market-support measures for the technology option ‘solar thermal cooling or air-conditioning'. In cooperation with a total of 22 organizations (12 research institutes, 5 universities and 5 companies) from eight countries numerous useful reports and tools have been created to improve the quality of solar cooling systems with significant contribution of the Austrian partners.
IEA SHC Task 49/IV focussed ist work on important research questions on solar process heat within the three subtasks: Process heat collectors, their application, comparison and possible standarization; Process Integration and process intensification as required interlinkage between solar heat and production processes; Design Guidelines, case studies and promotion as key for market penetration.
The focus of IEA SHC Task 51 ‚Solar Energy in Urban Planning’ has been placed on the topic of solar energy integration in urban environment. Hereby, different international examples, options and processes for planning and implementation of solar energy measures in cities throughout the world have been screened, outlined and equipped with recommendations for further development. The core outcomes of the project address different options and possibilities for optimization of planning processes, framework conditions, tools, methods and education aiming to attain more effective and timely understanding as well as integration of solar energy in urban context.
IEA SHC Task 52 focused on the analysis of the future role of solar thermal heat in integrated urban energy systems. The potential of solar thermal applications to cover the low-temperature heat demand in future low-carbon energy systems was investigated against the background of the rapidly changing framework conditions in the energy sector. Best practice examples for the integration of solar thermal systems into urban energy systems were evaluated and documented.
Within the framework of the IEA SHC Task 53 'New Generation (NG) Solar Cooling & Heating Systems', solar-electric and solar-thermal air-conditioning systems were investigated. The main objective was the development and documentation of reliable and economical NG system solutions. A comprehensive comparison of different NG systems as well as the elaboration of support measures for the market launch are core results of the international cooperation.
IEA SHC Task 54 was an interdisciplinary, collaborative project with the main focus on significant price reductions of solar thermal systems. Measures to achieve a reduction of the customer price up to 40% included simplified system designs, standardized components and cost-efficient materials and production and installation processes.
Despite the large potential for integrating large solar thermal plants into district heating and cooling networks, the share of solar heat worldwide is below 1%. The aim of this project was to analyse the technical, economic, and regulatory barriers that hinder a faster market development of such systems, and to propose solutions to support the growing heat market. The results (roadmaps, data, information) are available in the form of fact sheets.
