About

History

• 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 http://mayer.pro to the domain pvcalc.org.
• 2015 The website was redesigned to make it mobile-friendly in March 2015. The new look is live since April 5th 2015.
• 2023 The website is being completely redesigned.

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