What does the price of photovoltaic modules depend on

Why are solar PV module prices declining?

The study reveals several other important findings. Market and technological development are key factors explaining the decline in solar PV module prices. Moreover, government policies such as public budget for R&D in PV and feed-in tariff for solar PV are effective in reducing the price of solar PV modules.

What are solar PV module prices?

Solar PV module prices refer to the cost of the PV modules. Population density, the political stability index, renewable energy consumption and per capita carbon dioxide emissions series are all obtained from the World Bank (WB). Real GDP per capita series is taken from Federal Reserve Bank of St. Louis (FRED).

What is the dependent variable of solar PV module price?

The dependent variable is the log of solar PV module price. The log of imports of solar PV panels is used as a proxy of trade flows. Several exogenous variables are added to control for aggregate supply and demand effects.

Does a 1% increase in imports affect solar PV module prices?

However, the coefficient in absolute value is lower than unity, meaning that the model satisfies the stability condition. The empirical analysis reveals that a 1% increase in imports of solar PV cells and modules is associated with a 0.1% decline in solar PV module prices on average, all other things being equal.

How do market-stimulating policies affect the cost of PV modules?

Market-stimulating policies have played a central role in driving down the costs of PV modules, with private R&D, economies of scale, and learning-by-doing together contributing an estimated 60% of the cost decline in PV modules between 1980 and 2012.

What factors affect the development of the solar PV market?

Economic and non-economic factors affecting the development of the solar PV market and the evolution of prices are relatively complex. Over the past two decades, the global market has experienced a substantial decline in solar PV module prices.
