A perspective on 50% solar power evolution to support 100% CO2 free electrical energy production

The 100% CO2 free electrical energy production is a new national and international goal for mitigating climate change. In this race towards achieving this goal till year 2050, solar photovoltaic production is one of the important variable of the equation. But is it feasible in terms of scaling up in this short period the today world production of photovoltaic equipment? How far we are with today achievements and what effort is needed worldwide to accomplish this challenge? The paper presents a possible evolution of solar equipment manufacturing and gives an image of the effort needed to accomplish the goal in different scenarios of having 50% PV production in a mix of energy production targeting 100% CO2 free electrical energy production until 2035, 2040, 2045 or 2050. The scenario results endorse that the Paris Agreement targets are feasible in terms of panel production capacity and that there are options for earlier deployments, specifically applicable until 2040 or 2045, with lower CO2 emissions till 2050, to better address climate concerns.
