Install rooftop solar on the fourplex, 4200 block of Central Ave
This fourplex's low-slope roof sits in full South LA sun producing nothing; the LBC Energy Petal is net-positive energy, and rooftop PV is its primary instrument here. Standard: NEC 690 + AHJ permit + utility interconnection; LBC Energy petal net-positive energy Proof: permit + torque/flash log + AHJ inspection pass + production reading photo + GPS Method (Rooftop solar PV installation to NEC Article 690 + local AHJ permit, per SEIA/NABCEP install best practice — licensed/credentialed crew; assess→install→verify in one job, ~480-960 min): 1. ASSESS: verify the approved permit plan set matches the roof (structure, rafter condition, shading, array layout); confirm the main panel rating and the planned interconnection method; photograph existing roof + panel before work. 2. Install flashed roof attachments and racking to the structural plan (torque to spec, flash every penetration watertight); document torque checks. 3. Mount modules, run conduit/wiring, and land the inverter(s) and NEC 690 disconnects and labels exactly per the plan set; a licensed electrician makes and inspects the electrical terminations. 4. Commission: energize per the inverter checklist, measure open-circuit/operating values against design, and record initial production. 5. VERIFY: pass the AHJ final inspection and submit utility permission-to-operate; photograph the completed array, labels, and production reading; leave the owner the as-built + warranty packet. Equipment: fall protection (anchored harness) + hard hat + gloves (site PPE), PV modules, racking/flashing, inverter(s), conduit and NEC 690-rated disconnects per the approved plan set, torque wrench + multimeter/clamp meter + irradiance or production-check tool, approved permit plan set + utility interconnection application Done when: Every roof penetration flashed and photographed; racking torque log complete; AHJ final inspection passed and utility permission-to-operate submitted/granted; Initial production reading recorded and within design tolerance, with photo of the meter/app; As-built plan + labels photographed (NEC 690 rapid-shutdown/disconnect labeling in place)
How this work is done
A documented method, so this packet comes out the same whoever does it. Typically 480–960 minutes. Method of record: Rooftop solar PV installation to NEC Article 690 + local AHJ permit, per SEIA/NABCEP install best practice — licensed/credentialed crew; assess→install→verify in one job
Bring
- fall protection (anchored harness) + hard hat + gloves (site PPE)
- PV modules, racking/flashing, inverter(s), conduit and NEC 690-rated disconnects per the approved plan set
- torque wrench + multimeter/clamp meter + irradiance or production-check tool
- approved permit plan set + utility interconnection application
Steps
- 1. ASSESS: verify the approved permit plan set matches the roof (structure, rafter condition, shading, array layout); confirm the main panel rating and the planned interconnection method; photograph existing roof + panel before work.
- 2. Install flashed roof attachments and racking to the structural plan (torque to spec, flash every penetration watertight); document torque checks.
- 3. Mount modules, run conduit/wiring, and land the inverter(s) and NEC 690 disconnects and labels exactly per the plan set; a licensed electrician makes and inspects the electrical terminations.
- 4. Commission: energize per the inverter checklist, measure open-circuit/operating values against design, and record initial production.
- 5. VERIFY: pass the AHJ final inspection and submit utility permission-to-operate; photograph the completed array, labels, and production reading; leave the owner the as-built + warranty packet.
If it does not match the plan
- Rotted/soft decking, undersized structure, or panel bus rating below plan -> STOP: route back to engineering/AHJ before any mounting.
- Any wiring or termination outside the licensed electrician's sign-off -> not done; no energization until corrected.
- Work at roof height without anchored fall protection -> STOP work immediately.
What counts as done
- Every roof penetration flashed and photographed; racking torque log complete
- AHJ final inspection passed and utility permission-to-operate submitted/granted
- Initial production reading recorded and within design tolerance, with photo of the meter/app
- As-built plan + labels photographed (NEC 690 rapid-shutdown/disconnect labeling in place)
