As simple as SolaRay panels are to install, there are still plenty of issues to consider when mounting them! We’ve compiled a few installation guidelines, tricks and tips from installers of our units here to help you figure out the best way to mount them. General Steps: One of our dealers, Heating Green, has a fantastic step by step guide showing all the steps you need to take! SolaRay Installation Manual: Be sure to read the SolaRay installation manual: SolaRay Install Manual as well as the SolaRay Technical Brochure


Tools Needed: For basic surface mounting, you’ll want:

  • Philips Screwdriver
  • Measuring Tape
  • Pencil
  • Drywall Saw
  • Drill with 3/8″ bit

If you’re doing the electrical connections, you’ll also need:

  • Wire cutters/strippers
  • Utility Knife
  • Wire nuts
  • Needle nose pliers

Controlling Your SolaRayWe recommend the use of programmable thermostats to get the most out of your SolaRay infrared heaters. Programmable systems will enable you to heat the rooms you want, when you need to, saving the most energy. There are two primary options to consider – line voltage and low voltage thermostats.

Line Voltage: Line voltage thermostats run off either 120V or 240V and control the heaters directly themselves. Look for a thermostat that is rated to the total wattage of your heating system and is voltage compatible. For 240V panels, we strongly recommend using a DPST line voltage thermostat, versus a SPST.

Low Voltage: Ducoterra SolaRay panels can be controlled by low voltage thermostats as well, but require the additional installation of a low-voltage relay with power source. This can be used in scenarios where you might want to take advantage of the features provided by “smart” thermostats, such as a Nest or EcoBee. When controlling 240V systems, we recommend that the relay switches used are DPST.


Mounting Securely: All SolaRay panels ship with heavy duty toggle bolts – each one is rated to hold 70 pounds! Even so, mounting in drywall has it’s problems and as such we recommend the following installation patterns for our 4′ and 6′ units, especially if you live in an earthquake prone area, for maximum safety.

Other SolaRay Installation Tips

  • Bring a friend to help! Panel installation, particularly for the larger panels, is tricky solo. Using two ladders will make the job easier.
  • Position panels like you would a lighting fixture! Infrared will cover the room like a light, so space the units accordingly.
  • Install a good programmable line-voltage thermostat. One of the best ways to get the most out of your investment!
