What does a tube skylight cost; and what is it worth?


The average cost of a 14” VELUX SUN TUNNEL Skylight installed in Santa Rosa is $695.

(Three feet of tubing, one story home, composition roof, including tax) (Tubes come in 10”, 14”, and 22”)

What is it worth?

  • Santa Rosa has an average of 256 sunny days per year*.
  • On a sunny day the light from a 14” VELUX SUN TUNNEL is equivalent to 400 watts.
  • There’s an average of 9 hours of full sun per day. 
  • 400 watts X 9 hours = 3.6 kilowatt hours per day
  • 3.6 kilowatt hours X 256 sunny days = 922 kWh per year
  • Take an average electricity rate of $.12 per hour and multiply that by 922 kWh and you get a savings of $111 per year. (Of course the rate of electricity is going to go way up over 20 years, so this value will increase)
  • The VELUX SUN TUNNEL is warranteed for 20 years, so $111 X 20 years = $2220 saved from not turning on an electric light during the day.


So a 14” VELUX SUN TUNNEL Skylight is worth at least $2220 just based on the value of electricity.

Add to that the other benefits of installing a VELUX SUN TUNNEL Skylight:

  • It adds value to your home
  • You get light without heat loss or gain
  • You live and work in a more enjoyable environment
  • You are happier and are more productive
  • You are healthier- Getting enough sun exposure is proving to have many health benefits
  • You have used less electricity which means less CO2 in the environment, and more $ in your pocket
