What Our Customers Are Saying:

  • Our pool heater is 17 years old and broken. Instead of replacing it with a regular gas heater, we went solar. For only a few dollars more, my original pool builder came out and installed Thermocraft Solar Panels by CMI, and now we are making our money back by not having to pay heating bills anymore! We were paying over $300/ month with the gas heater! I also feel great about "going green" and helping the environment.
