State-of-the-Art Solar Water Heating Systems

Unmatched Performance and Durability

An unbeatable combination in solar water heating! Pacific West Solar has been producing and installing quality solar hot water heating systems since 1986. We run one of the valley’s best-equipped test facilities with products more rigorously tested than any standard requires. Our patented solar collectors use all copper absorber plates that are designed to withstand the extreme Arizona environment.

Our all copper absorbers have optically selective coatings and will provide years of consistent performance. Our patented Expansion Control fin/tube assembly reduces thermal stress that adversely effects the performance of other solar collector absorbers. Our collectors carry a 10 year repair or replacement warranty. All systems installed by Pacific West Solar are OG300 certified by the SRCC and have a Solar Fraction of .8.


The PWS Patented Solar Water Heating System

The Freeze Safe Solar Hot Water Heater is the result of 30 years of product development involving thousands of installations in the Phoenix area.

  3. Copper absorbers have optically selective coatings and will provide years of consistent performance
  4. Patented Expansion Control fin/tube assembly reduces thermal stress that adversely effects the performance of other solar collector absorbers
  5. Shut off switch on tanks allows for homeowner to conveniently shut off the electric back up for 7 months of the year
