Liten is a major European research institute and a driving force behind the development of the sustainable energy technologies of the future. The institute is spearheading the EU’s efforts to limit dependency on fossil fuels and reduce greenhouse gas emissions in three key areas: renewable energy, energy efficiency/storage and development of materials.
Our platforms, sophisticated tools for industry & the scientific/technical infrastructure/expertise to overcome technological hurdles
Liten's research teams work across a vast portfolio of renewable energy technologies. Cutting-edge photovoltaic technologies are developed at INES, the French National centre for solar research and R&D with Hydrogen and Biomass activities being managed from the LITEN's main site in Grenoble, Rhone-Alpes.
“Radically improving energy efficiency will reduce the need for investment in energy infrastructure, cut fuel costs, increase competitiveness, lessen exposure to fuel price volatility, increase energy affordability for low-income households and cut local and global pollutants improving consumer welfare” Source OECD Energy report, 2014

Electricity feed-in tariffs are decreasing, cutting into solar PV plant operators' margins. In this context, the ability to detect and identify loss-generating faults on the plants' equipment has become critical. To address this issue, and at the request of certain operators, Liten, a CEA Tech institute, is developing an algorithm capable of identifying and measuring sources of losses, from the collection of sunlight to the injection of electricity into the grid.
The researchers started by taking measurements on around 20 instrumented power plants. They are using the measurements to develop models and learning methods to assess as accurately as possible any losses likely to be generated by the PV modules, cabling, converters, and other components. The software will be tested on PV plants with different configurations to ensure that it is robust before it is made available to plant operators. Once it is installed, the software will display "loss diagrams" that can be used to provide an accurate assessment of plant operation.
Changes in the loss diagrams over time will also give an indication of degradation to plant equipment beyond the expected natural aging. Ultimately, the software will help improve plant LCOE (levelized cost of energy), the technical and financial indicator used to determine the economic viability of a plant.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
