In the LCA literature on PV technologies, the assumed solar irradiation ranged from 900 to 2,200 kWh/m2/yr. When these values were adjusted to 1,700 kWh/m2/yr (typical for southern Europe), the variability in the interquartile range of life cycle GHG emissions for c-Si PV technologies was reduced by 48%.

Environmental factors critically affect solar PV performance across diverse climates. High temperatures reduce solar PV efficiency by 0.4–0.5 % per degree Celsius. Dust can reduce PV output by up to 60 %, especially in desert regions. Terrain factors like albedo and snow present mixed effects on PV energy generation.

Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and shunt resistances.The light intensity on a solar cell is called the number of suns, where 1 sun corresponds to standard illumination at AM1.5, or 1 kW/m 2.
To assess the meaningfulness of installing solar photovoltaics (PVs) in buildings and infrastructures, we consider a carbon intensity (CI) balance perspective and assess whether installing PV at different orientations acts as a net CO2 sink or source when compared with the same amount of carbon that would be emitted using the local electricity mix.

A location that receives 5 kWh/m² of solar insolation per day, for example, can be said to receive 5 hours per day of solar power at an intensity of 1 kW/m². This makes PSH values particularly useful considering that solar PV modules are also rated under standard test conditions of 1 kW/m². Figure 8. Average daily solar insolation for several locations in
In this study, we investigated the intensity of greenhouse gas (GHG) emissions of a 30 MW PV plant using a life cycle assessment (LCA). Based on the LCA, we propose a roadmap to reduce emissions from PV manufacturing and deployment.
In the case of S-opta and N-90° PV installations in Bratislava, the carbon emissions would correspond to only 10%, and 62% of that would be emitted over the same lifespan using the present CI of the national electricity mix. In Athens, the corresponding ratios would be only 3% and 24%, respectively, and in Oslo, 146% and 830%.
Estimates for the CI of PV per kWh require assumptions about the electricity generated by a PV plant over its guaranteed lifetime (including assumptions about service lifetimes and degradation rates) and largely depend on the installation site, particularly on the local availability of solar resources.
Some of the key findings are: Solar irradiance is the most significant factor affecting PV performance, with the strongest impact near the equator. Higher temperatures reduce PV efficiency, with a typical loss of 0.4–0.5 % loss per 1 °C increase.
Apart from GHG emissions and mitigation, the environmental impacts of the entire solar PV industry chain vary both spatially and temporally.
Technical factors like cell efficiency, orientation, tracking systems, shading, and durability also affect system performance, and are the subject of other reviews [, , ]. The paper is structured to review six key environmental factors affecting solar PV performance in turn.
• Total life cycle GHG emissions from solar PV systems are similar to other renewables and nuclear energy, and much lower than coal. Harmonization increases the precision of life cycle GHG emission estimates for c-Si and TF PV, reducing variability in the interquartile range (75th minus 25th percentile value) by 65%.
