Parallel Solar String Design Solutions Lecture

Slide Presentation

Parallel Solar String Design

On January 10th, 2013, Gene Krzywinski, co-founder and CTO of eIQ Energy presented a #SolarMOOC lecture on how parallel solar design can simplify array design while reducing install cost and increasing power production.  You might find yourself asking, “is that really possible?”  The answer is, why- yes, it is possible.  Gene has all the data to prove how this type of system design can out-perform standard string inverter design.  If what you’re looking for isn’t in this lecture video, he welcomes you to contact him for more data or details (email Gene Krzywinski at:

Apparently the biggest obstacle, as with many aspects of the solar industry, is the learning curve. How does it work? How does this change the actual array design? How does this change my inverter selection? Can I use it in a DC mirogrid system?  What is the financial benefit of this design?  How is this different from a microinverter?These questions and more were answered in Thursday night’s lecture with Gene.

If you are actively working in the solar industry, especially with large projects- this is one of the technology break throughs that you should definitely farmiliarize yourself with.

As the industry grows, there are more and more solutions out there- being aware of these different options can help you to design the best system possible- meaning higher power production, faster payback, and ultimately – more clean energy and less fossil fuels.
