Several parts of the Mediterranean basin are experiencing grid parity nowadays, which is a sign that Photovoltaic (PV) technology has become competitive to conventional energy sources and may continue to develop without support. The net-metering policy takes advantage of the grid parity situation and is considered a step away from fading Feed-in Tariff schemes. Nevertheless, several policy variations...
The power produced from solar systems depends strongly on the prevailing weather conditions and more precisely on solar irradiance. Due to the dependence of such systems on the weather conditions the electricity injected into the grid is intermittent in nature with potentially negative impact on the grid operation. The quality and quantity of the electrical power produced from solar systems is directly...
This paper details the development of the pvpaR (PV Performance Analysis in R) web application built on open-source technologies for the automated and user-friendly evaluation of photovoltaic (PV) system performance and identification and classification of faults. pvpaR's ecosystem is based on the R statistical computing project, both for the back-end as well as for the front-end which uses the Shiny...
Net-Metering is an alternative mechanism to Feedin-Tariffs (FiT) for the promotion of small scale Photovoltaics (PV) generation, especially in the residential sector. Regarding the EU countries net-metering applications are relatively limited, but due to the interest of many parties, net-metering is expected to hold an active role in the coming years. This work focuses on the economic evaluation of...
Aim of this work is to investigate various options for effectively introducing Net-Metering in residential Photovoltaic (PV) installations in Greece. Net-Metering is considered as an ideal policy for keeping the PV market alive, at least until storage systems become competitive without subsidies. However, this policy has been adopted in numerous forms and variations throughout the world, which necessitates...
