To achieve a 55% GHG emissions reduction by 2030, the PV capacity in the EU and the UK would need to reach 455–605 GW. The annual PV market for the EU and UK could increase from 16.5 GW DC in 2019 to 50 GW DC in 2030. A substantial and growing market can provide the basis for reviving the European solar manufacturing industry.

The corresponding systems can achieve the diversity of land use, resulting in the mitigation of the issue of poor land utilization (caused by traditional PV panels' large footprint), which demonstrates the comprehensive benefits of clean energy supply, food production, and adaptation to climate change.
Solar irradiation directly influences the power generated from a PV system and varies by location and season, time of day, and weather. In the LCA literature on PV technologies, the assumed solar irradiation ranged from 900 to 2,200 kWh/m2/yr.
Photovoltaic power systems, as part of the electricity supply, are directly affected by related carbon policies in terms of their energy efficiency and carbon emissions. Through policy guidance and constraints, it is possible to increase energy efficiency and decrease the carbon footprint associated with photovoltaic power systems.
The annual PV market for the EU and UK could increase from 16.5 GW DC in 2019 to 50 GW DC in 2030. A substantial and growing market can provide the basis for reviving the European solar manufacturing industry. There is a potential to create more than 100 000 new jobs in Europe along the PV value chain.
The scarcity of raw materials is primarily due to finite resource reserves, increasing extraction difficulties, and the substantial energy required for processing. Low efficiency in solar panels implies that they generate less electricity than the amount of sunlight they capture, leading to an ineffective use of solar energy.
Up to 2030 all scenarios assume the same pathway with moderate growth in electricity use by 13–14% compared to 2015 (the reference year for the modelling) and achieve a 46% reduction of the GHG emissions (higher than the current policy for a 40% reduction).
