Core Pain Points and Corresponding Focus Areas

Core Pain Points		The focal point of the solution
Lack of power grid or high installation costs:	In remote areas, new parks, and other scenarios, laying cables is extremely costly and time-consuming.	Energy independence and rapid deployment:	Achieving 'where there is light, there is electricity', without relying on the power grid, quick installation, ready to use immediately.
High and continuous electricity expenses:	Traditional street lights incur huge electricity bills over long-term operation, becoming a continuous financial burden.	Zero electricity cost operation and investment return:	Utilizing free solar power generation to achieve energy self-sufficiency, reducing 'electricity expenses' to zero.
Blackout equals darkness, high dependency:	When the power grid is unstable or natural disasters cause power outages, public lighting systems fail, posing safety hazards.	Stable and reliable with disaster prevention and emergency response:	As an independent energy system, it can still provide normal lighting during main grid failures, enhancing urban resilience.
Carbon emissions and environmental pressure:	Traditional power sources may rely on fossil fuels, which do not align with the city's development goals of being green and low-carbon.	Zero-carbon environmental protection and green image:	Adopting pure green energy, silent, pollution-free, zero carbon emissions, setting a benchmark for sustainable development.
Extensive operation and maintenance management:	Lack of remote monitoring, delayed fault detection, maintenance entirely reliant on manual inspections, inefficient.	Intelligent management and efficient operation and maintenance:	Integrating smart controllers and Internet of Things technology to achieve remote monitoring, fault diagnosis, and strategy management.

Precise configuration of system core components

Photovoltaic modules (solar panels):

Technology: High-efficiency monocrystalline silicon PERC modules are used, with a conversion efficiency of 20% or more required.
Configuration: Based on local peak sunshine hours, accurately calculate the panel type and power to ensure sufficient power generation to meet nighttime lighting and fully charge the battery.

Energy Storage System (Battery):

Technology: Preferentially choose lithium iron phosphate batteries due to their longer cycle life (typically over 2000 cycles), better high-temperature stability, and safety.
Configuration: Battery capacity must ensure the system can operate normally for 3-5 consecutive rainy days, ensuring all-year-round lighting rate.

Intelligent Controller (System Brain):

Technology: Equipped with MPPT (Maximum Power Point Tracking) controller, which increases power generation efficiency by 15%-30% compared to traditional PWM controllers.
Function: Features light control + time control function, automatically sensing environmental light to turn lights on and off, and can operate at reduced power in the late night to save energy.

LED Light Source:

Technology: Utilizes high-efficiency (>170LM/W), low color temperature (3000K-6500K) LED lamps, ensuring maximum energy conservation while maintaining lighting effects.

Intelligent Control and Smart Management

Remote Monitoring Platform (Optional):

Install IoT modules on each light, using 4G/5G or LoRa communication technology to upload real-time status (voltage, current, battery level) and fault information to the cloud platform.
Function: Achieves map visualization, proactive fault alerts (such as low battery voltage, component damage), and remote strategy adjustments (such as adjusting light-on/off times, brightness).

Intelligent Strategy:

“People come, lights on” mode: In areas like park paths, add radar/infrared sensors to keep the lights dim when no one is around and automatically turn on fully when someone is present, greatly extending the endurance on rainy days.

Differentiated solutions for different scenarios

New Rural Areas and Remote Roads

Focus: Low cost, high reliability, maintenance-free

Solution: all-in-one solar street lights, compact structure, easy installation.

Design: Appropriately increase battery capacity to cope with rainy weather. The lamp pole design needs to be windproof and earthquake-resistant.

Urban Main Roads and Parks

Focus: Smart management, unified image, high brightness

Solution: A modular system can be adopted, with flexible configuration of high-power solar panels and batteries.

Design: The lamp pole design needs to integrate with the modern cityscape and reserve interfaces for future upgrades to 'smart poles'. It must be connected to the management platform to achieve centralized operation and maintenance.

Parks, Scenic Spots, and Trails

Focus: Ecological integration, landscape, flexibility

Solution: Use courtyard lights, lawn lights, low post lights, etc., with designs that harmonize with the natural environment.

Design: Adopt a 'sense+ dimming' strategy to achieve a soft effect of 'light without the lamp', minimizing light interference with plants and animals.

Emergency and Temporary Sites

Focus: Portability, rapid deployment, multifunctionality

Solution: Provide portable solar lighting lamps or mobile solar light towers.

Design: Integrate carrying, towing functions, and can charge mobile phones, provide Wi-Fi, suitable for emergency rescue, temporary construction sites, outdoor activities, etc.
