The expanded list of installation photo deliverables associated with the DOE Solar Access Program will be maintained, however, it should be noted that there are additional requirements based on specific manufacturers.

For the complete list of photo deliverables, see the standard Install (M1) Photo Documentation article.

Mounting System/Roof photos:

  • Attachments - Flashing & Sealant

  • Rail with Opto/Micro mounted + EGC + Wire management

  • Complete array with rail trimmed

  • Micro inverter model

  • Under array wire management

  • Tilt (one per unique roof pitch)

  • Junction boxes (cover off)

  • Photo of one PV Module serial number per site

  • PV Module label

Any project with a tree removed should have comprehensive photos showing the stump and surrounding area in relation to the structure with solar attachment.

Electrical photos:

  • Consumption CTs & Cell kits/cell modems required

  • Inverter(s) / Combiner box

  • Switches / Disconnects (fused only)

  • Main breaker & Busbar rating

  • Point of interconnection - close up & pull back

  • Pull back of BOS

  • Solar equipment serial labels

  • Completed wiring, including grounding/bonding in relevant enclosures

Commissioning

  • Fully commissioned, communicating, and producing system

  • Ensure all relevant screenshots from the commissioning app are uploaded

  • Screenshots should show a fully operational systems with all devices paired, active communication, reporting production and consumption including cellular connection signal.

  • Provide PCS settings, if applicable

Storage Photos

  • Transfer switch enclosure

  • Battery CT location and direction

  • Battery component legible serial labels

  • Pullback photos showing completed battery(s) location

  • Ensure you follow Battery communication wire instructions as they differ per manufacture

  • Installation of bollards in compliance with PR fire code, where applicable, would be prudent here

Production & Consumption Meter Requirements

All LightReach projects require production & consumption monitoring

  • SolarEdge inverters need an integrated revenue grade meter (RGM) with consumption CT ports, and additional CTs

  • Enphase systems require additional CTs for consumption monitoring

Rooftop Junction Boxes

  • Conductors landed in terminal block on DIN rail, grounding landed in ground bar and exposed conductors exiting box are protected from exposure by panel

  • If DIN rail not used, push-in or crimp connectors connectors preferred over wire nuts

  • Connector/lock ring used to transition into box from attic.

  • Watertight strain relief fittings used to transition from box to PV array.

  • Box is cut into shingles providing a clean look, and preventing water intrusion

  • If the junction box is more than two inches outside of the array, hard pipe to it.

  • Weep holes to prevent condensation and water retention in boxes

Best Practices - BOS

  • Conduit bodies reduce amount of conduit required and provides a much cleaner look

  • Duct seal and weep holes to prevent condensation and water retention in boxes

  • Prioritize Bottom Entry when possible

    • Top entry voids some warranties
