I have been in the attic ONCE, never plan to do it again, especially this time of year. Just the storage area is bad, the attic area and blown in insulation is much worse, and finding a place to safely walk is a real challenge. Having stated that, I do not understand solar lights, these are much more expensive then an additional NEW ceiling light, and the ceiling light works any time. Solar tubes only work when the sun is shining.

But back to your original question, I would not consider this a DIY project, unless you are really good cutting holes in your roof, and getting the seal right afterwards. This is not trivial work. You will also need a source for all of the components. Also, you and your house will get dirty and dusty when you cut the hole in the ceiling. For some reason, several of the installations I have seen are not straight tubes, but have one or more bends, so getting proper alignment might be interesting.

IMHO, if you are dead set on getting these, I would go with the professionals on this type of work, at least then you have someone to go back to if you have leaks or other problems.
