This study presents the innovation factors that have had an impact in the development of photovoltaic sector. Using a sample of 15 countries and data from 1992 to 2011, it was found that the application of public policy instruments, like: feed-in tariff, direct capital subsidies and investment funds have promoted innovation in the photovoltaic sector. Moreover, the deployment of the photovoltaic module price shows an inverse correlation with the number of international patents and the greatest effect is obtained with a time lag of two years. The quantity of oil reserves and the quantity of electricity exports with a lag of two years have also fostered innovation in the photovoltaic sector.
