Dual-system: Includes a solar power generation system
 (photovoltaic panels, controller, batteries) and a grid connection
 system, with automatic switching via an intelligent controller.

Advantage:

1. Minimal installation: Simply mount the pole and connect the wiring like a standard streetlight—no additional wiring required.
2. Uniform and aesthetically pleasing appearance.
3. Enhanced theft resistance

1. Flexible configuration: Expandable photovoltaic panel and battery capacity for enhanced power output and extended runtime.
2. Superior heat dissipation: Separation of battery and light source extends battery lifespan.
3. Easy maintenance: Ground-level or access panel battery placement facilitates simple replacement.
4. Relatively low cost.

1. 100% Lighting Guarantee: Completely solves power shortages during prolonged rainy periods.
2. Solar Priority: Zero electricity costs on sunny days, maximizing energy savings.
3. Configurable Optimization: Battery capacity can be appropriately reduced to lower initial costs.
4. Highly Intelligent: Enables remote monitoring and energy consumption management.

Disadvantage:

1. Power limitations: Constrained by the size of the lamp housing and heat dissipation capabilities.
3. Significant heat dissipation pressure: Impacts the lifespan of both the light source and battery.
4. Difficult maintenance: Battery replacement requires working at height.
5. Relatively high cost: The large housing contributes to elevated expenses.

1. Complex installation: Requires separate mounting of solar panels and battery boxes, with significant wiring effort.
2. Bulky appearance.
3. Risk of battery theft or water damage (requires protective measures).

1. Highest cost: Incorporates two systems, making it the most complex in structure.
2. Most complex installation: Requires both solar system installation and grid power cable connection.
3. Grid dependency: Loses the independence of a fully off-grid system.

Application：

Courtyards, residential walkways, park
landscape strips, and rural roads not classified
as main thoroughfares. Prioritizing aesthetic
appeal and ease of installation.

Medium-to-high power, high-demand scenarios:
such as main rural roads, county roads, plazas,
and areas requiring long-term high-brightness
illumination. Suitable for most outdoor functional
lighting applications.

Critical scenarios demanding extremely high reliability: such as
urban main thoroughfares, key transportation hubs, commercial
districts, or any area where weather-related outages are
unacceptable. An optimal choice for “smart cities.”
