THE SHORT ANSWER
LCEC asks applicants to attach a single-line diagram, major-equipment specification sheets, an aerial plan or picture showing the disconnect and meter, and the final passed inspection. [1]
Collect the approved design
Request the final one-line and equipment schedule, not the early proposal sketch. Check that module, inverter and battery models match the installed labels. Mark superseded drawings so a future service provider does not diagnose from the wrong configuration.
Preserve manufacturer sheets
Store the exact data sheets and available installation or operating instructions for each major component. A generic family brochure may omit ratings or communication details needed for service. Use searchable filenames containing the manufacturer and model.
Keep location evidence
Save the aerial or site plan and the original meter-disconnect photo. These help explain conduit paths and utility access after landscaping or construction changes. Never open equipment merely to improve the documentation.
Confirm inspection identity
The final inspection record should match the address, permit and installed scope. If the jurisdiction closed a permit after a correction, keep the final result and the correction notice. A passed inspection is important evidence but does not replace LCEC’s interconnection approval.
Duplicate the homeowner copy
Do not leave the only closeout file in an installer portal. Save a homeowner-controlled copy and a secure backup. Add monitoring credentials, LCEC correspondence and support contacts so the next owner or service company can use the technical package.
Before your next conversation
- Obtain the as-built one-line.
- Save exact equipment specification sheets.
- Keep aerial and meter-disconnect evidence.
- Archive the final inspection and LCEC approval.
