Ultimate 2021 PV Solar Energy with PVSol Premium/Excel/PVsys

Course instructor: NewWay Academy

NewWay Academy are a collective of professional and competitive electrical engineers, who now specialise in delivering video-tutorial online courses across electrical engineering, robotics, electronics, programming, and embedded systems. The real draw of this particular course is the attention paid to the calculation and designing of renewable energy off-grid and grid-tie PV systems, utilising not just one, but four different methods.

Whilst most course instructors focus on the use of the PVsyst program to calculate for the design of your system, NewWay Academy teach you how to use PVSol Premium, Excel, and manual calculation as well, meaning that at the end of this course you’ll be ready to calculate your every need, when beginning to construct your own photovoltaic system. The course can get quite complex though, so is perhaps best engaged once you’ve achieved at least a basic understanding of the fundamentals of renewable energy/have a base foundation in solar training.


  1. Four different methods for PV calculation
  2. NewWay pulls their knowledge and expertise from a wide pool of experts


  1. Course is not necessarily ideal for absolute beginners
  2. Spelling and grammar of course materials not up to native-English standards
