Over 125 years of combined solar and energy storage engineering experience

Based in Campbell, California, Paired Power was founded in 2015 by Tom and Aaron McCalmont. The company was born out of the family’s solar engineering firm, McCalmont Engineering, which designs ~8% of the total solar project capacity in the U.S. each year.

Together, Aaron and Tom patented their direct-DC approach to EV charging via solar energy in 2018, and Paired Power has been a leading innovator in the space ever since.
