The IEA Photovoltaic Power Systems Programme (PVPS) conducts joint projects in the application of photovoltaic conversion of solar energy into electricity. A number of activities initiated under the programme are considered to be complete (though in some cases further work is being undertaken in another Task). The completed tasks are:

• Task 3. Use of photovoltaic power systems in stand-alone and island applications
• Task 5. Design and grid interconnection of building integrated and other dispersed photovoltaic systems, concluded in 2003
• Task 6. Design and operation of modular photovoltaic plants for large scale power generation, concluded in 1997
• Task 7. Photovoltaic power systems in the built environment, concluded in 2003
