Abstract
Solar photovoltaic technology grows rapid nowadays due to many advantages including the generation of low-cost electricity compared to other technologies. The Greek National Plan for Energy and Climate foresees that solar photovoltaic energy will have a pivotal role in the clean energy transition of the country. The energy generation from solar-PV systems in 2050 is foreseen to correspond at 32.47% of the electricity demand in Greece while the required land area for the installation of solar-PVs corresponds at 0.92% of the total area of the country. The installed power of solar photovoltaics in 2050 will correspond at 53.38% of the total installed power of renewable energy systems in Greece while the installed power of the power storage systems will correspond at 61.54% of the total installed power of solar-PVs. The majority of solar photovoltaic systems are nowadays installed either on the soil or on rooftops of buildings. However, more configurations for the installation of solar-PV systems are available including their installation in buildings’ facades, on the surface of water reservoirs, vertically on the ground and on the soil allowing the co-production of electricity and food. New types of solar-PV modules have emerged and some of them are already used commercially. These include, semi-transparent photovoltaics, double-phase photovoltaics, agrivoltaics and organic photovoltaics. The role of several external factors affecting positively or negatively the growth of solar photovoltaic systems in Greece have been analyzed according to PESTEL methodology.
