The results show that, first, the overall solar PV power efficiency of the 26 countries is 0.762, which leaves significant room for improvement, and that most of the countries with high average solar PV power efficiency are high-income.
As shown in Fig. 4, solar PV power efficiency also grew slowly in the initial stage. However, the center of solar PV generation in China is different from the center of massive consumption of solar PV generation, meaning there is no transmission line to connect the western region with the eastern region effectively .
The average solar PV power efficiency in these countries fell to a minimum value of 0.686 in 2007 and reached a maximum value of 0.906 in 2020.
The SFA model removed the effects of the external environmental variables and statistical noise on solar PV power efficiency. The results are summarized below. The first-stage results indicate that the solar PV power efficiency of the 26 countries considered fluctuated upward and then downward between 2000 and 2020.
Due to the importance of the impact of solar PV generation in addressing climate change and achieving sustainable development, the vast majority of economies recognize the significance of assessing solar PV power efficiency.
At the national level, the adjusted solar PV power efficiency scores of all countries except China and India exceeded 0.9, which is close to the production frontier side. In particular, the United States and Austria were on the production frontier side for 13 years and 11 years, respectively.

Solar Panel Energy Efficiency and Degradation Over Time
Solar Efficiency in Percentage(%) = ((Maximum Power /Area)/(1000)) * 100%. Maximum Power is the highest amount of energy output of the panel, written in watts (W). Area means the surface area of the solar panel, which is written in square meters (sq.m.). For example, the maximum power of a panel is 200W and has an area of 1 sq. m. So, using the solar panel …
