💡 Frequently Asked Questions (FAQ)

1. Why integrate IoT into solar street lights?

IoT enables remote control, predictive maintenance, real-time monitoring, and intelligent dimming, enhancing system performance and reducing costs.

2. Is IoT-based solar lighting more expensive?

Yes, by about 10%–20% initially, but it offers a fast ROI within 2–3 years via reduced maintenance and energy usage.

3. Does the system require constant internet?

Most use cellular connections (4G/NB-IoT) to sync data periodically. Offline fallback ensures basic lighting still functions.

4. Is the data secure?

Yes. Systems use end-to-end encryption and certified security standards like ISO 27001 to protect transmitted data.

5. Can existing lights be upgraded?

Yes. Retrofit controllers can be added to convert legacy lights into smart, IoT-connected systems.
