retired from home design/build, which included PV solar. Now in a manufactured home which needs addons and repairs. We live in the Arizona Rockies.at 6800' elevation; cool, winter snows, summer monsoons. Now age 80 and "losing it", so having problems learned new stuff, so help is welcome!
Formerly used QuickCAD which won't run on Windows10, so now it's Librecad on Linux Mint.
