Solar Light Q & A
Q: How long do solar lights last?
A: Quality units operate 5-8 years with battery replacements every 2-3 years.
Q: Can solar lights work in winter?
A: Yes, but runtime decreases 20-30% in cold climates. Choose models with -20°C tolerance.
Q: What maintenance is required?
A: Clean panels monthly, check connections annually. No wiring needed.
Q: Are solar lights bright enough?
A> Modern LED models match 40W-150W traditional bulbs (e.g., 6000lm = 150W halogen).
Q: How to prevent theft?
A: Use tamper-proof bolts, ground-embedded poles, or remote monitoring.
