Our Facility

The Qnergy manufacturing facility is equipped for high volume manufacturing of engines and systems in over 60,000 square feet.

This dedicated production line is a fully operational, semi-automated assembly line utilizing the latest production equipment. Following rigorous and stringent quality and safety standards, our team is able to produce, test and deliver our various products on time.


Qnergy’s legacy is based on decades of experience providing high-reliability, no-maintenance, long-life missions including both terrestrial and deep space remote power generation platforms.  Reliability is deeply ingrained within Qnergy’s culture.  Qnergy chooses to provide high-performing products to our customers by designing our products with test. Design “with test” means designing our products to stringent reliability targets and then “proving” this reliability by testing and intentionally failing parts within extreme, harsh operating parameters.  Tests to failure show us exactly where the margins are, establishes the validity of our products within their specified operating envelope, and helps speed up product improvement cycles. Here at the Qnergy Manufacturing site, as well as at our field test sites, Qnergy uses long-life product “success” testing to show that we know and expect reliability.

With millions of total hardware operating hours Qnergy continues to demonstrate its capacity to design and manufacture product to the most stringent of reliability requirements.
