Advanced Power Inc. (API) was built from humble beginnings and thrives in small Oklahoma towns. We got our start in Canton in 1988, and have since grown into a state-of-the-art facility in Weatherford. That growth makes API one of the largest and most trusted companies in the solar pumping industry today. It’s a success story we’ve worked hard to earn, and continue to write every day.
Thousands of customers worldwide know they can rely on the exceptional customer service and highest quality products that we provide. Our friendly and experienced sales staff works closely with you to choose the right system that suits your project’s unique needs.
To reach more customers globally and expand the availability of our solar products in other markets, we changed the name from Robison Solar Systems to Advanced Power Inc. in 2005. Butch Robison still owns this great family business and stays true to its humble roots.
