Q1: “What is the ideal luminous flux (lumens) for commercial solar street lights?”

▲ Answer: For high-traffic areas (such as highways and city main roads etc.), we recommend ＞10,000 lumens to ensure bright, uniform lighting. For low-traffic areas (such as city subsidiary roads, real estate, pathway, parks, residential, small parking lots, sidewalks etc.), 4,000–8,000 lumens are sufficient.

Professional tip: Always match the output lumen/lux value to the project’s scale and safety requirements.

Q2: “What materials ensure long-term durability?”

▲ Answer: Prioritize brand-new aluminium (rust-resistant) and tempered glass solar panels. Avoid cheap recycled aluminium alloy with very thin housing or even plastics!

SOLWAY Solar Street Lights are designed to withstand extreme temperatures ranging from -30°C to 60°C and offer over 10 years of weather resistance. 

Q3: “What is the core component in solar street lighting system?”

▲ Answer: Battery it plays a very important role. Solway used the latest prismatic LiFePO4 technology which offered us Brand new & Grade-A quality and excellent after-sales service. Solway refused the recycled ones from energy vehicles to ensure more safety & explosion-proof. There are many factories use this recycled battery due to the cheap cost but the quality can not be guaranteed. Solway battery the cycle life up to 5000 times, and in the market mostly used the traditional cylindrical LiFePO4 with 2000 times cycle life. 

Q4: “How important is the waterproof rating (IP)?”

▲ Answer: IP65 or above is essential! This rating ensures full dust protection and resistance to heavy rainfall—perfect for coastal or rainy environments. 

Q5: “Can solar street lights be used in areas with limited sunlight?”

▲ Answer: Yes—but it’s critical to choose high-efficiency Monocrystalline silicon solar panels and ensure the battery supports 3-5 days backup of autonomy.

Smart models from SOLWAY Solar Lights can automatically adjust brightness to conserve energy.

Q6: “What certifications should I look for?”

▲ Answer: Make sure factory ISO9001&ISO14001 certified and the product has CE, RoHS, and IEC testing, which verify compliance with EU safety and environmental standards, along with high-quality manufacturing.

Q7: “How can I reduce maintenance costs?”

▲ Answer: Choose solar street lights with a modular design for easy part replacement, and options for Dimming control or PIR motion-sensing technology to extend battery life by up to 30%.
