Frequently Asked Questions (FAQ)

Top Questions About Hardoll Solar Lights

What is a LiFePO4 battery and why does Hardoll use it?

LiFePO4 (Lithium Iron Phosphate) is a safer, longer-lasting battery chemistry compared to standard Li-ion. Hardoll uses LiFePO4 batteries in its solar lights because they offer 2,000+ charge cycles (vs 500 for Li-ion), better thermal stability in Indian climates up to 60°C ambient, and zero risk of thermal runaway. This means your solar light keeps working reliably for 5–7 years.

What does the Hardoll warranty cover and how long is it?

Hardoll offers a warranty of up to 5 years on solar lights — one of the longest in the Indian solar lighting market. The warranty covers manufacturing defects in the LED module, solar panel, battery, and housing. Normal wear, physical damage, and incorrect installation are excluded. Warranty duration varies by product model. Register your warranty at hardollenterprises.com/pages/warranty within 30 days of purchase.

What does IP65 and IP67 waterproof rating mean?

IP65 means the light is protected against low-pressure water jets from any direction — safe for rain, sprinklers, and general outdoor use. IP67 means it can withstand temporary submersion in water up to 1 metre for 30 minutes. Most Hardoll outdoor solar lights are rated IP65 or higher, making them suitable for Indian monsoon conditions.

How long do Hardoll solar lights last on a full charge?

Most Hardoll solar lights provide 10–12 hours of illumination on a full charge, depending on the model and lighting mode. Lights with motion sensors last longer as they operate at reduced brightness until motion is detected. A full charge typically requires 6–8 hours of direct sunlight.

Can I use Hardoll solar lights during monsoon season?

Yes. All Hardoll outdoor solar lights are IP65 or IP67 rated, designed to withstand heavy rain and monsoon conditions. During extended cloudy days, battery backup may reduce to 4–6 hours. We recommend placing lights where they receive maximum sunlight during breaks in the monsoon for optimal performance.

Do Hardoll solar lights work without direct sunlight?

Hardoll solar lights charge in indirect or diffused sunlight, but charging efficiency is reduced. On fully overcast days, expect 50–70% charge compared to direct sunlight. For best performance, install the solar panel facing south (in India) with no obstructions from trees or buildings blocking sunlight.

Does Hardoll offer bulk pricing for housing societies and hotels?

Yes. Hardoll supplies solar lights in bulk to housing societies, hotels, resorts, industrial campuses, and government projects across India. Visit b2b.hardollenterprises.com for project pricing, or contact our B2B team for custom quotes. We have supplied solar lighting to leading hospitality and infrastructure brands nationwide.

How do I install Hardoll solar garden lights?

Most Hardoll solar garden lights are designed for DIY installation — no electrician needed. Simply push the stake into soft ground, or use the included mounting hardware for hard surfaces. Ensure the solar panel faces upward with no shade cover. Detailed installation guides are included with every product, and video tutorials are available on our YouTube channel.

What is the difference between solar street lights and solar flood lights?

Solar street lights are pole-mounted, provide directional downward illumination for roads, pathways, and driveways, and typically range from 60W to 300W. Solar flood lights provide wide-angle illumination for open areas like gardens, parking lots, and building facades, and are wall-mounted or bracket-mounted. Hardoll offers both types with LiFePO4 batteries and motion sensor options.
