About Us

Alternative Energy Products

Depend on Hardtke Enterprises, Inc. of Billings, Montana, for a large selection of alternative energy products. We have more than 50 years of experience in the industry and we’re dealers for every North American manufacturer.


Hardtke Enterprises, Inc. was formed in 2002, after our founders, Allan and Joanne Hardke, decided there was a need to share some of the technical information concerning the alternate energy systems they represented. Starting from their home office in Billings, Hardtke Enterprises, Inc. started with a dealership for wind turbine generators, later other products were added from top manufacturers.


To complete the alternative energy product line Photovoltaic (PV) solar products were added to our inventory. When the Stirling engine and fuel cell technology develop cost-effectiveness, products will be offered using those technologies.


We understand the ins and outs of alternative energy and have dedicated 35 years to wind power alone. Rely on our informed specialists to provide you with the best alternative energy services.
