Solar Street Light Maintenance Plan — Inspection, Cleaning & Evidence Logs (Tender-Ready)
A maintenance plan is not “nice to have” — it is how you protect autonomy, prevent ingress/corrosion issues from becoming outages, and keep warranty claims enforceable. This page gives a risk-based schedule (by environment and vandal risk), a practical inspection checklist, and the documentation pack you should require at handover.

TL;DR (What maintenance actually prevents)
- Early shutoff: PV soiling, shading growth, wrong dimming settings, charging deficit.
- Intermittent faults: moisture ingress, connector oxidation, loose fasteners/cables.
- Warranty disputes: missing serial mapping, missing commissioning record, no evidence logs.
- Theft/vandal loss: hardware loosening, missing anti-tamper measures, no inspection routine.

How to use this plan
This plan is designed for procurement and operations:
- Owners: define the minimum inspection frequency and evidence logs required.
- Contractors: follow the checklist and submit the evidence pack.
- Suppliers: provide spare parts policy and warranty workflow aligned with this plan.
Procurement tip: don’t accept “maintenance-free” claims. Instead, require a clear schedule and a log template.
Risk-based maintenance frequency (choose the correct tier)
Pick a tier based on environment and vandal risk. You can tighten or relax frequency after 3–6 months of real data.
| Tier | Where it applies | Routine inspection | Cleaning focus | Notes |
|---|---|---|---|---|
| Tier 1 (Low) | clean sites, low public access | Quarterly | As needed | Still require evidence logs for warranty |
| Tier 2 (Medium) | urban streets, mixed access | Monthly–Quarterly (site decision) | Scheduled + after storms | Increase checks for cables/connectors and fasteners |
| Tier 3 (High) | dusty/desert, monsoon, coastal, high theft zones | Monthly (minimum) | Scheduled (critical) | High focus on PV soiling, sealing points, corrosion, anti-theft hardware |
Use these pages to define risk assumptions:
Routine maintenance checklist (what to inspect every visit)
1) PV module: output killers (soiling + shading)
- Check visible soiling layer (dust, salt film, bird droppings) and clean if it reduces charging.
- Check shading risks (tree growth, new signs/buildings). Document changes with a photo.
- Check PV bracket integrity and fasteners.

2) Fasteners, mounts, and anti-theft hardware
- Check pole bracket, arm bracket, and luminaire mounts for loosening.
- Verify anti-tamper fasteners and locks are present and intact (high-risk zones).
- Look for pry marks or tool access points.
Related:
3) Cables, connectors, and ingress indicators
- Inspect cable routing for abrasion, cuts, UV cracking, and loose strain relief.
- Inspect connectors for oxidation/corrosion (especially coastal/humid).
- Check cable glands and sealing points for gaps or mis-seating.
- Look for condensation or water marks inside lens areas (if visible).

4) Lighting performance (quick functional verification)
- Confirm light turns on at dusk and follows the expected dimming profile.
- If PIR is used: verify base brightness and boost response behavior.
- Note flicker, random resets, or abnormal dimming behavior.
Related:
Trigger-based maintenance (do this when specific events happen)
- After storms/monsoon weeks: inspect glands, sealing points, connectors, and condensation indicators.
- After extended cloudy periods: check for “SOC walk-down” symptoms (early shutoff pattern). Compare to energy budget assumptions.
- After theft/vandal incident nearby: check anti-theft hardware and add inspection frequency temporarily.
- After construction work near the road: re-check shading, dust levels, and cable safety.
Reference:
Evidence logs (this is what makes warranty enforceable)
Require these logs as part of operations (and store them in one project folder):
1) Serial-to-location mapping (mandatory)
- Every unit serial number mapped to pole ID/location.
- Updated when units are replaced/moved.
2) Commissioning settings record (mandatory)
- Dimming mode and profile used (time / PIR / hybrid).
- Any configuration changes recorded with date and reason.
3) Maintenance log (mandatory)
- Date, technician, site/pole ID
- Actions taken (cleaning, tightening, replaced parts)
- Photos (before/after) when relevant
- Observed symptoms and next follow-up date
Reference pages:
Spare parts policy (must be defined in procurement)
Maintenance fails when spare parts are not planned. Require the supplier to define:
- Spare fasteners/locks (anti-tamper parts) for high-risk sites
- Common consumables: cable glands, seals (if serviceable), connectors
- Replacement policy for batteries/controllers (time, method, evidence required)

Copy/Paste RFQ Clauses (Maintenance & O&M)
Clause 1 — Maintenance schedule (mandatory)
Supplier/contractor shall provide a maintenance schedule aligned to site risk (environment + vandal risk) including routine inspections, PV cleaning triggers, and post-storm inspection requirements.
Clause 2 — Evidence logs (mandatory)
Supplier/contractor shall provide and maintain: serial-to-location mapping, commissioning settings record, and maintenance logs including photos where applicable. These records are required for warranty claims.
Clause 3 — Spare parts policy (mandatory)
Supplier shall provide a spare parts policy covering anti-tamper hardware, connectors/cable glands, and defined replacement workflow for batteries/controllers including expected lead time and evidence requirements.
Clause 4 — Bid comparability rule
Bids missing a maintenance schedule and evidence-log templates shall be labeled “Not Comparable / High Risk” before price comparison.

FAQ
How often should solar street lights be cleaned?
It depends on soiling rate and rainfall. Use a risk tier: dusty/coastal sites often need scheduled cleaning, while low-soiling sites can use “as needed” cleaning triggered by visible film and runtime decline symptoms.
What is the minimum documentation required for warranty protection?
Serial-to-location mapping, commissioning settings record, and maintenance logs with clear dates/actions and photos when relevant.
What’s the fastest way to reduce early shutoff complaints?
Align dimming settings with the energy budget and verify PV cleanliness/shading at critical charging hours—then document changes in the commissioning record.
