BIPV for Norway

Welcome to the BIPVNO project webpage.

Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or facades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power, although existing buildings may be retrofitted with similar technology.

The advantage of integrated photovoltaics over more common non-integrated systems is that the initial cost can be offset by reducing the amount spent on building materials and labor that would normally be used to construct the part of the building that the BIPV modules replace.

The term building-applied or building-attached photovoltaics (BAPV) is sometimes used to refer to photovoltaics that are a retrofit, i.e., applied to the building after construction is complete. Most building installations today are BAPV.

The BIPVNO project objective is to identify and develop robust BIPV-solutions that are suitable for Norway and to provide a scientifically founded knowledge-base for future developments of new materials, components and solutions that can be tailor-made for the Norwegian climate and solar irradiation conditions.

About the project

Several research organizations and industrial partners have started up the project "Building Integrated Photovoltaics for Norway (BIPV Norway)" with support from the Research Council of Norway (RCN). The project is organized in four work packages addressing the following issues:

(WP1) Performance of BIPV/BAPV-installations in Norway. More about WP1.

(WP2) Technical integration of photovoltaics in buildings. More about WP2.

(WP3) Challenges with snow and ice formation. More about WP3.

(WP4) Solar irradiation issues related to Nordic conditions. More about WP4.

Two PhD candidates will work with a focus on experimental laboratory investigations of building integrated photovoltaics with respect to durability and robustness, and advanced materials surface development for preventing snow and ice formation on building integrated photovoltaics.

The main activities for BIPV Norway are: (WP1) Data collection and documentation, system performance evaluation, technical and architectural integration. (WP2) Developing robust components and solutions, accelerated aging and durability testing in Nordic climate exposure. Testing and investigating the link between aesthetic quality and PV efficiency, environmental assessment and carbon footprint evaluations. (WP3) Snow and ice influence on solar energy yields and impact on surface robustness and durability. Advanced materials surface development for avoiding snow and ice formation. (WP4) Effect of diffuse and variable spectrum radiation on energy production, and advanced materials and solutions for better utilization of insolation.

Although the BIPV Norway project focuses on Norwegian climate conditions and building traditions, the results will be of relevance and applicable also to other countries and geographical locations. International collaboration and participation at various stages in the project is anticipated.

BIPV resources

Norway is one of the countries taking part in the International Energy Agency Photovoltaic Power Systems Programme IEA PVPS, where several member countries partake in joint projects - also called Tasks - for the application of photovoltaic conversion of solar energy into electricity. The BIPVNO project is part of the ongoing Task 15 "Enabling framework for the acceleration of BIPV", where we have the opportunity to learn from other more developed European BIPV markets and at the same time provide input from our own building traditions and experiences.

Relevant information from the IEA PVPS Task15, as well as links to other websites and reports of particular interest to the BIPVNO project, will be posted in the Resources section. Conferences where project results have been presented are listed in the Conferences section. Publications and popular-scientific articles resulting from the BIPVNO project are listed in the Publications section.

Project meetings

The project had a successful kick-off meeting at Gardemoen the 26th February 2015.
The day consisted of presentations of the initial project plans and activities by the different work package leaders, as well as group work with all the project partners to dicuss and adjust the contents and contributions in the project.

The project partners meet at least twice a year for project updates and workshops. During the recent project meeting in Porsgrunn 21-22 November 2016, site visits were arranged to Isola (factory Porsgrunn), Statsbygg (University College Porsgrunn), and Elkem Solar (factory Heroya), to learn more about BIPV/BAPV products and systems.
