LONDON, Feb. 8, 2013 /PRNewswire/ -- Policy changes in the renewable energy sector and the ongoing debt crisis are set to have a profound impact on the market for frequency inverters in the solar and wind energy industries across Europe. While the reduction in subsidies is expected to dampen the European market in the near future, low maintenance costs and the promise of high returns on investment (ROI) will buoy frequency inverter market revenues during this turbulent phase. Unlike Europe, the market is expected to see strong growth in other regions such as Asia and North America. New analysis from Frost & Sullivan ( http://www.motors.frost.com), Strategic Analysis of the Frequency Inverters Market in Solar and Wind Energy Industry, finds that frequency inverters in the global solar and wind energy markets earned $6.00 billion and $2.84 billion, respectively, in 2011. Frequency inverters are estimated to rack up $ 14.58 billion in the solar industry and $7.09 billion in the wind industry by 2018. Policy changes in Europe are predicted to hike taxes and reduce subsidies and investment in the renewable energy sector in the next 2 years. The increase in feed-in tariffs could discourage investment in the renewable energy sector. "The impact of such changes on the frequency inverters market will be high during the short-term and moderate during the medium- and long-terms," cautioned Frost & Sullivan Industrial Automation and Process Control Practice Industry Analyst Sivakumar Narayanaswamy. "Market participants are planning to adapt to this new policy landscape by streamlining operational costs and developing sustainable strategies." Both solar and wind frequency inverter manufacturers are also grappling with falling investments due to the debt crisis. In this scenario, the lower maintenance costs and higher ROI of frequency inverters will prove beneficial in encouraging continued uptake.
