7/ We find an empirical cross-study relationship that links available solar resource to the future PV share in the energy system. Applying this relationship & performing a population-weighted average yields a 61% global PV share by 2050. The Solar Age is projected across studies.

6/ Location matters: the more solar resource (full load hours), the higher the PV share in future energy systems. There are significant outliers in both directions, mainly due excellent other renewables, e.g. hydropower, wind, geothermal – or lack of relevant other renewables.

5/ Why do solar PV projections vary so much? Key reason is cost assumptions. Outdated or pessimistic costs lead to systematically underestimated roles of PV. Still, low-cost PV may not lead to very high PV shares, as diverse factors drive overall low-cost energy system solutions.

4/ Most of the investigated highly renewable energy transition studies agree: solar PV & wind will provide 80–99% of electricity by 2050. Two groups for the PV share are detected: about 25-50% and 70-95%, with the latter overcoming the issues of post (2) plus sunbelt conditions.

3/ Solar PV share greatly varies between studies ranging from 5-98% with many studies underestimating the future role of PV due to pessimistic cost assumptions & low-complexity modelling. Typical issues: outdated cost, low spatial & temporal resolution, lack of power-to-X options.
