As the global community intensifies efforts to limit warming to below 2°C, the transition toward a decarbonized energy system is increasingly reliant on solar PV energy source integration. A groundbreaking study conducted by researchers from Leibniz University Hannover and LUT University has analyzed 60 peer-reviewed energy transition studies to determine the future trajectory of solar power. The research underscores that solar PV has entered the global energy system faster than any other electricity source in history, driven by plummeting capital expenditures and near-universal availability.
The systematic review reveals that most models project solar PV and wind power to account for 80% to 99% of electricity generation by 2050. However, the specific contribution of solar PV varies wildly, ranging from 5% to 98% in different models. This variance is largely attributed to outdated cost assumptions; approximately 18% of reviewed studies still utilize capital expenditure (capex) figures exceeding €500/kW, despite current market prices having already fallen well below that threshold. The research notes that capex figures for utility-scale solar PV in 2050 are projected to range between €151 ($174.1) and €720/kW.
For EPC contractors and solar developers in India, the study highlights a critical gap in how energy potential is perceived versus how it is modeled. Models that utilize coarse temporal resolution—such as representative time slices rather than hourly simulations—consistently underestimate the viability of solar. Developers should note that projects incorporating a diverse ‘toolbox’ of technologies, such as bifacial modules, floating solar, and integrated storage, are consistently favored in high-accuracy models. Furthermore, the shift toward using cheap solar electricity for green hydrogen production offers a massive opportunity for developers to tap into hard-to-electrify industrial sectors.
The research suggests that as modeling techniques evolve to include higher temporal resolution and a broader range of PV applications, the projected dominance of solar will likely increase. For the India renewable energy sector, which is currently scaling rapidly to meet ambitious 500 GW non-fossil capacity targets, these findings validate the aggressive push toward solar-led energy planning. As the sector moves beyond simple power generation into green ammonia and industrial heat applications, stakeholders must align their long-term strategies with the reality that solar PV is no longer a niche technology but the foundational pillar of the future energy grid.
