How many watts do solar parking lot lights need?

A typical commercial parking lot needs 40W–80W solar LED lights on 6–8m poles, spaced 18–25m apart with IESNA Type V (round) or Type IV (forward-throw) distribution. Plan for 30–50 lux at the driving lane and 10–20 lux in parking bays. Our Parking Lot Application series covers 30W–100W and ships with photometric files for site designers.

Can solar lights cover a parking lot overnight?

Yes. A properly sized solar parking lot light (e.g. a 60W unit with a 60–80Ah LiFePO4 battery) runs dimmed to 30–40% from dusk to midnight, then full brightness on motion until dawn — typically 3–5 nights of autonomy without sun. Our Parking Lot Application fixtures use this profile by default and can be re-programmed for 24/7 full-output sites.

Do solar parking lot lights work in winter or cloudy weather?

Yes, when sized for your worst solar month. Add 30–50% extra battery capacity and panel wattage if your site sees frequent cloud cover or short winter days. Our fixtures are tested at -30 °C to 60 °C with an optional battery heater for sub-zero climates.
