An article describing this inexpensive and very efficient solar heater for a shop, studio, or playroom. This project provides an great combination of solar heating and daylighting -- it makes for a space that is a delight to be in. My all-time favorite solar project.
The article explains why this $4 per sqft collector can do as well as well or better than commercial collectors costing $30 per sqft, and provides full construction details. It also describes a new version that can be built with only basic tools.

Workshop or Studio Sunspace
This is an inexpensive and simple project to convert a garage that has a south facing overhead garage door into a solar heated and lighted workshop, studio, playroom or sunspace/greenhouse.
It’s hard to overstate how much more pleasant this makes the shop to work in -- on sunny days its toasty warm and very well lighted. I think it would also work well as a studio, kid’s playroom, a place to grow a few plants, or maybe just a place to sit and read the newspaper.
I really like the way the existing garage door is used as movable insulation to reduce night heat loss. The combination of the new outer glazed doors, the existing overhead garage door, and the simple shade cloth sliding screen make a simple but very effective way to control the shop environment, harvest some free solar heat, and reduce green house gas emissions.
These simple collector doors at $4 per square foot do as good a job of solar heating as commercial solar collectors costing $30 per square foot – and, they give you the added bonus of good lighting and a view!
Of all the solar projects I've completed, this one has been the most satisfying in its simplicity and usefulness.

An Alternative to Building Your Own Doors
Instead of making the glazed doors yourself, this suggestion makes use of a commercial door system for the outside glazed doors. These door systems are used in Florida and like climates to allow a room or sunspace to have a glazed wall, or to stow the glazing panels off to the side to fully open the area to the outside. The idea is to use one of these door systems instead building your own outside doors. This looks like it would work fine to me, and looks like it would result in a very attractive and functional system. Several types of sliding and folding door arrangements are made (more....

This suggestion came from Ed via Home Power -- thanks!
Here are some excerpts from Ed's email, and some pictures he provided:
