Photovoltaic power plants are considered to be environmentally friendly solutions to the production of electricity. Solar energy conversion does not release toxic compounds into the environment. However, the construction of solar power plant components (photovoltaic modules, sup-porting structure, inverter station, electrical installation) is extremely consumptive of energy and materials. Massive volumes of minerals, fossil fuels, and electricity are consumed during the manufacturing process. Efficient management of energy and environmental resources seems to be critical for national policy. It is crucial to admit that the post-consumer management of the components of a photovoltaic power plant is connected with a certain quantity of energy and matter and a negative impact on the natural environment. A life cycle assessment was carried out on a real 2 MW photovoltaic power plant located in the northern part of Poland. The analysis was carried out applying the ReCiPe 2016 model and the Life Cycle Assessment (LCA) approach. The impact of the examined renewable energy system was evaluated using 22 impact categories and 3 emission areas (air, water, soil). Life Cycle Assessment analysis was carried out for 2 post-consumer development scenarios (landfill and recycling). The examination of the collected results reveals that photovoltaic modules are the element causing the most negative environmental repercussions connected to the release of dangerous compounds into the atmosphere. Post-consumer development in the form of recycling would provide major environmental benefits and reduce detrimental environmental consequences across the whole life cycle of the photovoltaic power plant. The obtained research results enabled the formulation of pro-environmental recommendations aimed at the long-term development of the life cycle of solar power plants.

This article’s focuses of photovoltaic installations, which are becoming more and more popular in Poland and around the world. A short theoretical introduction to photovoltaic cells is presented, and the aim of the research is distinguished. Then, the formulas for the parameters characterizing solar cells are derived. The parameters that determine the highest efficiency of solar cells are specified in the next section. In the experimental part, tests of a selected photovoltaic installation were carried out. Based on the research, we conclude that temperature and sunlight have a significant impact on the efficiency of solar cells.

This study’s objectives were to evaluate the life cycle of a 2 MW solar power plant in northern Poland and provide suggestions for enhancing this kind of installation’s environmental performance. Eight years of operating data were examined under the assumption that 2000 MWh of energy was produced annually on average. The evaluation took into account two waste management scenarios—landfill and recycling—and was carried out in accordance with the ReCiPe 2016 methodology. Human health and water resource usage had the most environmental effects (7.08 × 10⁵ Pt—landfill), but recycling greatly reduced these effects (−3.08 × 10⁵ Pt). Terrestrial ecosystems were negatively impacted by the turbines’ water consumption (8.94 × 10⁵ Pt—landfill), which was lessened in the recycling scenario. The water and soil environment was greatly impacted by released pollutants, such as zinc and chlorinated hydrocarbons, whose emissions were greatly decreased by material recovery. Particularly detrimental was sulfur dioxide (SO₂), which is the cause of PM 2.5 particle matter, which is dangerous to the public’s health. Recycling has helped to lower these pollutants and enhance the quality of the air. Reducing methane and other greenhouse gas emissions can help reduce CO₂ emissions, which were the most significant factor in the context of climate change (1.91 × 10⁴ Pt—landfilling). Recycling lessened these impacts and decreased the need to acquire virgin raw materials, but landfilling was linked to soil acidification and the depletion of mineral resources. According to the findings, even “green” technology, like photovoltaics, can have detrimental effects on the environment if they are not properly handled at the end of their useful lives. Recycling is turning out to be a crucial instrument for lowering negative effects on the environment, increasing resource efficiency, and safeguarding public health.
