Solar tube skylights, also known as light pipes and tubular skylights channel the light from a small skylight, down through a high reflectance duct, to a ceiling mounted diffusing lens.
Solar tube skylights are advantageous in deep roof construction or when the area to be lighted is too small for a standard sized skylight.
Typical installations include bathrooms and closets, but multiple tubes can be installed in larger rooms for a dramatic effect.
The diffusing lens resembles a typical ceiling mounted glass fixture. Most diffusers are round, but a transition box can used to convert the round tubing to a square diffuser for suspended ceilings.
Solar Skylight Cost
Factors that determine the cost of a solar tube installation are the length and diameter of the tube, whether you install it yourself or hire a professional, and the composition of your roof. If your roof is tile or metal expect to pay 15 - 20% more for installation.
You can purchase a complete 14" diameter solar tube DIY kit for around 0. Professional installation will run you half again as much, or 0. If you're purchasing multiple units don't forget to ask for a discount.
Are Solar Tube Skylights a DIY Project?
The installation seems to be relatively straight forward; cut a hole in the roof for the skylight, another in the ceiling of the room below for the diffuser, and connect the two with the reflective duct. But this is not a project for novices; especially if your home has a metal or tiled roof.
Will A Solar Skylight Reduce My Electric Bill?
Yes, but the savings will be minimal. However, installing a solar tube in a highly trafficked room like the bathroom will save you more money than one installed in a closet.
Will The Federal Government Help Me Pay For My Solar Tube Skylight?
You have until December 31, 2010 to collect a 30% tax credit, excluding labor, up to ,500 for eligible skylights. Also, check with your State Department of Energy for additional rebates or sales tax credits.
