Measure on top of the count

After the count, Sweinstein traces conduit and feeder runs to panels, inverters and chargers. Lengths are worked out exactly from each sheet's confirmed scale. The AI traces; the math is done in code.

Ask about your local code

Ask about CEC or NEC rules for solar and EV charging in your province or state. Answers quote the code books your company uploads and follow the project's province or state. They are a reference, not legal advice.
