Just finished the first seventh pass of my system schematic using Dia. My friend Devan suggested using this solar template. The only object I had to make myself is the symbol for the pressure relief valve. My schematic is based on the OG-300 certified SunEarth system schematic that's listed on the SRCC (Solar Rating and Certification Corporation) website. I wanted something easier to read than the SRCC diagram. I need to get this schematic `proofread' and do some final cleanup and then submit it to the SF Department of Building Inspection which I hope to happen this week.
