What Solar Light Covers
PLB builds LiFePO₄ solar lighting batteries on self-developed cells — 30Ah to 100Ah for 30W to 80W luminaires, 3,000 to 5,000 cycles with 80% or more retention, one wide-temperature model covering −30 °C to 65 °C, IP65 sealing with 1,000-hour UV testing, 35% smaller enclosures in cylindrical, prismatic or pouch formats, and 4G cloud monitoring for campus-scale fleets. Zero maintenance, zero electricity cost and five-year TCO down from ¥8,200 to ¥500 per lamp.
Six Solar Light Sub-Scenarios
Each sub-scenario page covers the pain points that scenario faces, how PLB helps you solve them, a comparison table and the recommended models — so you can compare and choose faster.
Municipal Street & Road Solar Light
Township and trunk-road lighting with zero replacement over five years: 3,000+ cycles, one nationwide SKU and 94% lower TCO than lead-acid.
Garden & Landscape Solar Light
35% smaller packs that hide inside the luminaire, in cylindrical, prismatic or pouch formats, IP65 sealed and 1,000-hour UV tested against yellowing.
Commercial Campus Solar Light
30Ah to 100Ah packs for 30W to 80W luminaires with 12–15 hours of runtime, 4G cloud management for 200-light fleets and a 2–3 year payback.
Remote & Off-Grid Solar Light
Fully self-sufficient lighting for villages and remote roads: no grid connection at all, saving ¥100,000+ per kilometer of cabling, with IP67 and IK08 impact protection.
Car Park & Plaza Solar Light
100W of constant brightness for 12 hours with under 3% variation, and no more high-pole maintenance: ¥750,000 saved across 100 lights.
Advertising & Signage Solar Light
98% lower five-year cost with the battery hidden inside the sign: 30–40% smaller, three enclosure formats and a ten-year design life.

Frequently Asked Questions
The questions lighting contractors and municipal buyers ask most about LiFePO₄ solar-lighting batteries in the Solar Light scenario — −30~65 °C (one model nationwide) and 3,000+ (deep cycles), and what it takes to qualify.
What has to change on the luminaire before a LiFePO₄ pack goes into the Solar Light scenario?
The same capacity fits in 30–40% less volume, with cylindrical, prismatic and pouch formats and five-day custom sampling, so the pack goes inside the luminaire. Typical models for Solar Light builds are LL-SL-MUNI30 and LL-SL-MUNI50.
Does output stay flat through a whole Solar Light night?
The pack is rated 3,000–5,000 cycles with 80%+ capacity retention, which covers a five to eight year design life without replacement.
How is the pack sealed and thermally managed in Solar Light duty?
Specification: −30~65 °C (one model nationwide). The sealed housing resists UV and moisture, and the BMS protects the pack at low temperature. Endurance: 3,000+ (deep cycles).
Is a special charger needed in the Solar Light scenario?
The solar controller charge profile is supported; the BMS limits charge current and protects the pack at low temperature.
What warranty and after-sales support apply in the Solar Light scenario?
Standard products carry a full warranty backed by lifetime technical support, with terms confirmed on the quotation; export packing is UN 38.3-certified with MSDS. Tell us the luminaire wattage, daily lighting hours and installation latitude — our engineers size the pack and recommend the matching model within 24 hours.
Need a Selection Recommendation?
Tell us the load, backup time and installation space — our engineers will recommend the matching battery within 24 hours.
