Solar-2 plots sunlight penetrating through a window with any combination of rectangular fins and overhangs.

SOLAR-2 also plots hour-by-hour 3-D suns-eye view movie of the building wall. Prints annual tables of percent of window in full sun, radiation on glass, etc. NOTE: Many of its functions have also been added to HEED, SBEED, and Climate Consultant.

Please treat this version of SOLAR2 as a DEMO only because the New Installer created December 2016 seems to be unable to accept new design data input. We are working to correct it and will post a revision as soon as possible (generation 4 released July, 1999, original release Sept., 1987) [over 10,000 downloads since Feb., 1999]
