Solar Tracker Plants Revived

Case Study

Date:   October 2014

Description:  This solar PV portfolio is made up of seven plants, approximately 1 MWp each for a total of 7MWp, composed of biaxial trackers. It is located in Puglia, Italy and was constructed between 2009 and 2010.

The portfolio was experiencing severe underperformance and safety issues. The underperformance was attributed to:

  • Bad system design
  • Lack of proper maintenance
  • Complete absence of proper monitoring
  • Issues’ Root cause never properly investigated

The plants were producing well below the Base Case Scenarios leading to cash flow issues with overall financial performance of the investment below the budgeted values, up to 25% below base case scenario, leading to an average yearly loss of revenues of 150.000 euro per MW. In addition, huge costs were incurred in order to preserve even the suboptimal operational status of the plants.

The case study outlines how Alectris was able to resurrect these solar plants leading to a dramatic increase of the solar portfolio’s profitability.
