All-in-One vs Split Solar Street Light: Which One for Your Project?
It's the first question every project buyer asks, and the honest answer is: it depends on your road, your climate and who will maintain the system. Here's the decision framework we use with customers across 55+ countries.
Quick comparison
| Factor | All-in-One | Split |
|---|---|---|
| Installation | 15 minutes, no wiring | 2–4 hours, wiring + battery box mounting |
| Max practical power | Up to ~400W with large panel | Effectively unlimited (separate panel array) |
| Autonomy | 2–5 rainy days (battery in housing) | 5–10+ days possible |
| Maintenance | Swap whole unit or open housing | Replace battery/panel independently |
| Theft risk | Low (all components on pole top) | Higher (ground-level battery box) |
| Unit cost | Lower for ≤120W | Lower per watt above 200W |
Choose all-in-one when…
- Roads are narrow-to-medium (3–10m) and light requirements are ≤120W class
- Labor is expensive or skilled installers are scarce — the 15-minute install matters
- Theft and vandalism at ground level are a concern (battery stays on top of the pole)
- You need fast, large-quantity rollouts — like our 3,000-unit Philippine municipal project
Choose split when…
- It's a major highway or wide boulevard needing 200W+ of real light output
- Your region has long rainy seasons demanding 5+ nights of autonomy
- Local technicians will maintain the system and value field-replaceable batteries
- Existing poles must be reused with an independent panel array
Climate is the tiebreaker
In the Gulf, we deploy hybrid solar-grid split systems because July heat pushes battery chemistry to its limits. In Southeast Asia's monsoon zones, split systems with oversized panels survive where compact all-in-ones struggle. In equatorial Africa with strong, consistent sun, all-in-ones deliver the best cost-per-lumen-year by far.
Bottom line
Under 120W and want speed? All-in-one. Above 200W or brutal seasons? Split. Mixed portfolio? Most of our distributor partners stock both. Send us your road width and location and we'll spec the right architecture — with a free DIALux simulation to prove it before you commit.
