Design and installation of a grid-connected PV system

2014

As the worlds electrical demand is being more covered by photovoltaic (PV) systems, Germanyinstalled 3.3 GW of the worlds PV systems in 2013 compared to 0.6 MW being installed inNorway. Irradiation measurements done for southern Norway indicates that the conditions formore PV systems being installed are good when comparing irradiation in Grimstad to Hamburg.This thesis addresses the initial steps of planning and building a PV system to analysing howthe inverter handles the varying irradiance in southern Norway.To investigate the opportunities in Grimstad, a Theia HE-t 3.8 string inverter from Eltek wasinstalled along with 23 de-rated PV modules to constitute a PV system of 2.116 kWp. The PV…
