2019 is a good year for the solar energy market.
Global solar installations will return to double-digit growth, with European demand returning to 2012 levels.
About 90 countries are expected to increase their portfolios of solar photovoltaic (pv) panels. The increase in the global market is attributed to government policies on carbon emissions reduction, growing energy demand and continued decreases in solar pv and inverter prices. Solar PV module prices fell 32% and average PV inverter prices by 18% in the past two years.
