Are there studies on solar PV power efficiency at the national level?

(1) There are few studies on solar PV power efficiency at the national level. Although solar PV generation is widespread and can provide electricity to meet the energy needs of economic development, few analyses have been conducted to assess solar PV power efficiency.

What is the importance of assessing solar PV power efficiency?

The importance of assessing solar PV power efficiency is of interest to the vast majority of economies. A country should measure solar PV power efficiency and keep related records. Therefore, this study used economic dimensions in its analysis. The remainder of the paper is organized as follows.

Why is solar PV generation important?

Due to its pollution-free, environmentally protective nature, solar PV generation is one of the most developed energy conversion methods . Meanwhile, declining fossil fuel savings and rising greenhouse gas emissions have intensified research activity in the field of solar PV generation.

How does government policy affect solar PV power efficiency?

They also have relatively greater expectations of non-fossil-fuel energy generation, which will also increase the level of attention given to solar PV generation; furthermore, more government policies and researcher input will influence solar PV power efficiency , , . 3. Results and discussion

How did the financial crisis affect solar PV power efficiency?

The average solar PV power efficiency score fluctuated around 0.8 for the five years from 2000 to 2004 and decreased for the four years from 2004 to 2007, indicating that the global financial crisis of 2007–2008 had a significant impact on the economy and on energy.

How does solar power save energy?

By harnessing solar heat and radiation for electricity generation, the project has achieved significant energy savings and emissions reductions. Each year, the project saves an equivalent of 15,394.489 tons of standard coal, effectively reducing reliance on fossil fuels.
