Performance Ratio and Degradation Rate Analysis of 10-Year Field Exposed Residential Photovoltaic Installations in the UK and Ireland

Abstract: As photovoltaic (PV) penetration of the power grid increases, accurate predictions of return on investment require accurate analysis of decreased operational power output over time. The degradation rate in PV module performance must be known in order to predict power delivery. This article presents the degradation rates over 10 years for seven different PV systems located in England, Scotland, and Ireland. The lowest PV degradation rates of −0.4% to −0.6%/year were obtained at the Irish PV sites. Higher PV deg… Show more

“…The UK's base inflation rate was 2.1 at the point of this analysis and was adjusted conservatively. The degradation rate of crystalline panels in England was found to be in the range of 0.7% to 0.9% per year [85]. The PPA prices have been estimated based on the document [86] produced by Department for Business, Energy and Industrial Strategy (BEIS), UK.…”

“…The capacity to foresee the production yield of power over a long period is of fundamental significance to developing the photovoltaic (PV) industry. Two main drivers are the productivity with which daylight is transformed into electrical energy and the behavior of this interrelation with time [11].…”
