Abstract
Increasing restrictions on the emission of greenhouse gases by the standards and the European Union’s policy aims at increasing the share of renewable energy sources in the energy mix of the Member States. Subsequently, we observe a rapid increase in the installed capacity of the renewable energy sources. Renewable energy sources are currently the fastest growing sectors of energy generation, specifically the photovoltaic sector. In 2005, the total installed capacity in photovoltaic installations in the European Union was about 2.17 GW, while in 2019 it was already over 130 GW. Currently, due to many forms of incentive governmental measures the construction of photovoltaic installations is rapidly increasing with installations mounted on private houses and buildings. The article presents selected issues concerning the failure modes of photovoltaic installations and a comparative assessment of the estimated and the real measured electrical production of an operational photovoltaic installation. The Solar-PV power plant design approach proposed in the paper considers the failure modes to enhance the plant’s reliability.
Highlights
The continuous development of modern society creates an ever increasing demand of electricity, since the WW-II
The largest installed capacity is in Germany with 49 GW, which accounts for almost 38% of the total energy in photovoltaic installations in the European Union [19,20,21]
Based on the results obtained from the measurements of the amount of energy produced from a photovoltaic installation, it can be concluded that the results obtained from simulation programs and calculations using NASA-SSE databases may differ significantly from the real values
Summary
The continuous development of modern society creates an ever increasing demand of electricity, since the WW-II. The EU 2020 Climate & Energy package targeted an increase in the share of renewable energy sources up to 20% in EU countries [5]. Solar energy is a major renewable source to generate electricity through photovoltaic cells [15,16,17]. The largest installed capacity is in Germany with 49 GW, which accounts for almost 38% of the total energy in photovoltaic installations in the European Union [19,20,21].
