Key improvements to the methodology include: A collector is tracking the sun during daytime, focusing the direct sun irradiance via Fresnel lenses into optical fibers, which guide the solar light into the building. A case study in the rural municipality of Herrljunga was conducted and scaled to national level. However, there is a lack of high resolution data needed for solar variability studies, which demand dense solar irradiance monitoring networks. Results of our initial studies allow exploration of the variation patterns in solar yield depending on local and time-varying factors, which cannot be seen in coarse level solar planning tools.
Decentralized energy storage of in total 86 MWh capacity achieves the same result.
Secondly, variations in de-ratings throughout the day, mainly due to shading, are explored in a process referred to as Tuning. Lastly, high k pv related variance in the early morning and evening is detected and filtered. The transmission properties and coupling of solar light have been studied for glass core multimode fibers in order to verify their benefits for a solar fiber optic lighting system. And 3 a method which eliminates high variances in k pv based upscaling. For case 4 improvements on both models were introduced.
