Explore our core integrated and split-type lighting configurations engineered for high efficiency, durability, and smart monitoring.
In modern industrial and municipal engineering, solar illumination has evolved from primitive separate components to highly integrated formats. While the standard All-in-One (AIO) solar street light revolutionized quick installations by packing the PV panel, battery, controller, and light engine into a singular profile, it introduced distinct constraints. Specifically, fixed solar orientation, limited heat dissipation between battery cells and high-temperature LED engines, and strict limitations on solar panel sizing for high-wattage outputs.
The All-in-Two (Split-Type) system emerges as the optimal engineered balance. It segregates the solar panel from the integrated LED light fixture, housing the LiFePO4 battery pack, MPPT controller, and LED light engine within one structural cast aluminum assembly. By doing so, the photovoltaic module can be oriented dynamically toward maximum sunlight exposure, independent of the street lamp pole angle, while supporting significantly larger panel wattages (exceeding 100W up to 400W) without compromising the wind rating or thermal integrity of the luminaire.
Adjust solar panel tilting and azimuth values freely according to geographical latitude, optimizing annual yield and self-cleaning performance compared to flat AIO panels.
Separating the high-absorption solar panel surface from the battery/LED housing prevents cumulative solar heat from shortening the operational lifespan of the LiFePO4 battery pack.
How procurement managers, municipal directors, and industrial distributors analyze cost, quality, and carbon compliance parameters.
Large-scale public bidding and corporate infrastructure procurements for solar street lighting projects demand highly strict compliance, cost transparency, and technical certifications. Key challenges include:

Providing uniform, low-glare warm illumination using natural white 4000K CRI70 LEDs that secure walkways while preserving ecological balance.
To ensure 20+ years of street pole service and over 50,000 hours of LED operation, our design team works strictly with high-grade components. The chart below lists the architectural parameters of our All-in-Two systems:
Deploying a municipal-grade solar lighting grid requires structural and electrical steps to ensure reliability.
Determine solar insolation ratings, local wind drag values, and historical rain trends to size the solar panel and battery buffer correctly.
Develop foundation designs, select hot-dip galvanized conical steel pole thicknesses, and configure structural tilt brackets.
Integrate the MPPT charge controller, route connections, configure smart dimming profiles, and link IoT nodes if required.
Execute waterproofing cycles, perform continuous burn-in testing, verify battery capacities, and finalize regional compliance paperwork.
Ensuring safe shipping, fast customs clearance, and adherence to international electrical, mechanical, and safety standards.
Navigating global compliance protocols is critical when exporting high-capacity lithium battery systems and structural steel components. Operating as an ISO9001 and ISO14001 certified company, Danyang Penelope Light Co., Ltd. ensures all wholesale configurations are packed, documented, and shipped to meet import standards in South America, Southeast Asia, the Middle East, and Africa.
Our shipping teams handle MSDS certifications and UN38.3 transport safety documentation required for lithium battery transport. This prevents transit delays, providing a secure supply chain from our production lines to your project destination.
Expert technical answers regarding structural design, battery chemistry, charge controller configuration, and installation guidelines.
All-in-Two designs separate the solar panel from the LED lighting fixture (which contains the battery and controller). This allows the solar panel to be tilted toward the sun for maximum PV harvest while keeping the LED light head oriented flat to the road. It also prevents battery overheating by keeping it separate from the solar panel's sun-exposed surface.
LiFePO4 (Lithium Iron Phosphate) offers better thermal stability, a longer life cycle (often over 2,000–3,000 charge cycles compared to 500–800 cycles for NMC), and remains safe under high temperatures (up to 65°C) without the risk of thermal runaway.
Hot-dip galvanization dips the steel into molten zinc, forming a metallurgical alloy layer. This coating blocks moisture and salt air, protecting the underlying steel pole for up to 30 years in coastal environments.
Our smart solar systems support Zigbee, LoRa, 4G, and NB-IoT protocols. These allow users to monitor battery status, PV charge levels, and light performance remotely, as well as configure smart dimming profiles from a central management system.
MPPT (Maximum Power Point Tracking) controllers track the optimal voltage of the solar panel in real time, converting excess voltage into charging current. This improves energy conversion efficiency by 15% to 30% compared to traditional PWM controllers, especially on cloudy days.
