77 High efficient standalone solar system design tool P. Nymann, F. S. Hansen DTU Photonics, Technical University of Denmark The purpose of this project is to create a mathematical model for valuation and component sizing of standalone solar systems. Solar energy is one of the most reliable, daily available and environmental friendly renewable energy sources; being unlimited, clean and free. Due to this and the increasing efficiency and decreasing costs of PV-panels, progressively more technologies incorporate/rely on solar energy. Other than being self-sustainable, solar powered standalone systems have the advantage of greatly reducing installation costs, as no cabling is required. Known examples of cabling cost include 700 €/m in Copenhagen and up to 2000€/m in Berlin 1. In order to leverage the technology, e.g. in standalone systems, to its fullest with minimal costs, it is necessary to determine the dimensions of the system components before development. To date no complete model exists for valuation and system sizing. This model developed in this project will be able to predict by simulation whether a standalone system is able to perform as desired, before putting the system into production. Entering component characteristics into the model, it is able to predict system performance at any given location by using solar irradiation data only. The model is developed in MatLab and is designed to simulate “light-2-light” systems e.g. park lights and bollards. However, the model can be readily expanded to incorporate any desired load, for instance a standalone electrical vehicle charging station, and a more user-friendly interface.
