In breakthrough research conducted by Danish researchers at the Department of Engineering, Aarhus University, the team has developed a model of solar cells.
Research in sustainable energy resources have picked up pace in the past few years, owing to the planet’s need to retain renewable energy. The team has hence created photovoltaic (PV) installations. According to reports, solar energy will be equivalent to wind energy within the realm of sustainable energy systems of the future. However, this will require a precise model for energy production through PV systems.
As a result, the latest project by Danish researchers is considered as a major breakthrough. According to reports of the scientists, the team collected global solar radiation, temperature and weather data worth 38 years. It used a spatial resolution of 40km x 40 km for the entire globe and also compared historical data for photovoltaic installations in Europe as part of the study. Based on these findings the scientists created an accurate model which can monitor performances of PV installations within a specific geographical region, at regional and local levels. In other words, the scientists can evaluate not only a single installation, but can also look at energy production in countries and continents via such PV installations. This discovery is especially important because it can enable energy systems to function optimally in the future.
Moreover, according to scientists producing green energy is not a challenge. The price of PV installations has fallen over the past 10-20 years. Hence, investments in PV installments is conducive. However, the new challenge faced by scientists is to link energy production from several small installations to country’s total energy demand and production from other sources.
Furthermore, the green energy system of the future depends greatly on renewable energy sources, which also depend on weather. There is therefore a demand for accurate knowledge of energy production. “PV installations will have a huge impact on the energy systems of the future, and planning systems based on models that do not take into account the outages in relation to the norm simply won’t work. Therefore, this project has gathered very detailed data over time for the last 38 years for the entire globe, so that the model can be used anywhere,” according to Assistant professor, Martha Victoria.
The research study was published in the journal Progress in Photovoltaics and is part of the RE-Invest project, funded by Innovation Fund Denmark.
