Mr. Kriendler is now fully certified with the North American Board of Certified Energy Practitioners (NABCEP) as a Photovoltaics (solar electricity) Installer.
Only 51 per cent of applicants across the U.S. made the grade in the gruelling four-hour mathematical solar exam.
But Mr. Kriendler was honoured to achieve 82 per cent.
He hopes others will follow him and "gain more credibility" with the internationally recognised qualification.
He said: "The environment isn't just about the future, it's about our present.
"Other countries are so far ahead of us in terms of renewables but Bermuda could quickly become a sustainable model if we wholeheartedly supported it.
"Sustainable solutions make sense, economically and environmentally, for Bermudians, for tourism and social stability."
Mr. Kriendler studied at the Solar Living Institute in California and worked with a PV installation crew, Real Goods Solar, before returning home and working as the photovoltaics specialist with Travis Burland at Bermuda Engineering Co Ltd.
He recently installed a PV system at his own home and wants to celebrate his exam success by "installing a sizable photovoltaic array in the near future".
He added: "I'm 95 per cent sure I'm the first and only Bermudian to obtain this certification to date — it's a pretty incredible feeling."
Mr. Kriendler said the NABCEP qualification is one of the more "rigorous and respected" certifications in the renewable energy industry.
He added: "In order to be eligible to even take the exam, a strict criteria of practical and theoretical prerequisites need to be met and the application process can take months.
"I knew I wanted to obtain this certification but I wasn't sure I'd be able to complete it in such a short timeline, even with my installation experience in California."
Mr. Kriendler was notified his application was accepted and he started studying for the NABCEP exam in July of this year.
He sat the exam in the San Francisco Bay area of California on September 11. There are only two chances a year to sit the exam in the U.S., with only 306 out of more than 598 installers passing the September exam.
Mr. Kriendler said the challenging multiple-choice exam was "a maze of calculations and questions relating to PV and the National Electric Code".
The passing grade was a high 70 per cent.
He anxiously kept checking the website to see if he had passed and almost lost hope as about six weeks passed. He found out he made the grade last week.
Mr. Kriendler said: "I was so anxious just to know one way or the other.
"When I saw I had passed, it was disbelief, then the excitement kicked in."
But it does not stop there for Mr. Kriendler —his "quest for further knowledge will continue indefinitely".
He now hopes to gain a NABCEP Solar Thermal (hot water) certification and eventually obtain a degree in electrical engineering.
