About PVCalc

PVCalc is provided by Mayer Analytics.


  • 2008 The first version of PVCalc was written in 2008 as an in-house tool. 
  • 2009 PVCalc was made freely available and the positive feedback encouraged us to add more features and improve the graphical representation over time.
  • 2012 On Aug. 5th 2012 PVCalc and all the other tools and resources about PV solar energy moved from the personal blog website to the domain 
  • 2015 The website was redesigned to make it mobile-friendly in March 2015. The new look is live since April 5th 2015.

We hope you will find PVCalc useful. Feedback is very welcome.
