Uzbekistan's urbanization process has accelerated significantly in recent years. New city development projects have been launched around major cities such as Tashkent, Samarkand, and Namangan, requiring extensive lighting infrastructure for newly constructed roads, landscape axes, and public spaces. Meanwhile, the Uzbek government has prioritized green energy and renewable energy as key national development directions, making solar streetlights a promising candidate for application in new city construction.
However, many projects have found in practice that lighting systems are treated as an add-on to road construction after completion, rather than being considered during the urban planning phase. This "post-construction" approach often leads to a series of problems, including shading limitations on photovoltaic panel installation locations, substandard uniformity of street lighting, and a mismatch between system capacity and actual needs.
I. Solar Energy Resources in Uzbekistan
Uzbekistan is one of the countries in Central Asia with the richest solar energy resources. Most parts of the country have an average annual peak sun hours of 5 to 6 hours, with the Tashkent region averaging about 5.2 hours, the Fergana Valley about 5.5 hours, and the southern regions even exceeding 6 hours.
This level is comparable to high-quality solar energy resource areas in the Middle East and North Africa, providing excellent natural conditions for the stable year-round operation of solar streetlights. Compared to Kazakhstan's winter challenges, Uzbekistan enjoys much more favorable conditions for solar energy utilization. The main constraints on system design stem from urban planning rather than natural resources.
II. The Necessity of Unified Consideration of Photovoltaics and Lighting in the Urban Planning Phase
The traditional logic of urban road lighting planning is: first, determine the road cross-section and landscape scheme, then have lighting designers select and arrange luminaires within the given conditions. This sequential process works well with municipal streetlights, but it has significant drawbacks for solar streetlights.
The power generation efficiency of solar streetlights is highly sensitive to the installation conditions of the photovoltaic panels. Shading is the biggest efficiency killer—street trees, buildings, and billboards in the urban environment can all block the photovoltaic panels at certain times of the day, leading to a significant drop in power generation. If this is not considered in advance during the planning phase, addressing shading issues after road construction is extremely costly.
Landscape boulevard projects have even higher requirements for the aesthetics of lighting; pole design, luminaire appearance, and color uniformity are all important indicators. Incorporating the form, size, and installation method of solar streetlights' photovoltaic panels into the landscape design during the planning stage can achieve a balance between function and aesthetics; however, retrofitting after the fact often forces compromises with existing conditions, significantly diminishing the effectiveness.
III. Key Technical Inputs in the Planning Stage
Solar Resource Assessment: During the urban planning stage, a solar resource assessment should be conducted for the project site. Monthly sunshine data should be obtained to identify the peak sunshine hours for the month with the lowest sunshine duration, serving as the design benchmark for battery capacity and photovoltaic panel power. Preliminary data can be obtained from public databases such as NASA POWER and PVGIS; for important projects, it is recommended to supplement with at least one year of measured meteorological data.
Shading Analysis: Using a 3D urban model and sunshine simulation software, a year-round shading analysis should be conducted on candidate photovoltaic panel installation locations along various road sections within the planning area. High-risk shading areas should be identified, allowing for adjustments to roadside tree planting locations, building setback distances, or lighting fixture arrangements at the planning level to fundamentally eliminate shading hazards. Road Lighting Grading Planning
Based on Uzbekistan's road lighting standards (referencing the CNP system or EN 13201 standard), the lighting requirements for roads of different grades within the planning area are classified and defined. The requirements for average illuminance, uniformity ratio, and glare control vary for different scenarios such as urban arterial roads, secondary roads, scenic walkways, and squares. Lighting indicators for each road segment should be clearly defined during the planning stage as input conditions for the design of solar streetlight systems.
IV. Design Considerations for Solar Lighting along the New City's Landscape Axis
The landscape axis is a core space showcasing the city's image in the new city plan. Lighting design needs to achieve a balance between functionality and artistry.
Integration of Lamp Form with Photovoltaic Panels
The design of landscape streetlights should consider photovoltaic panels as an aesthetic element, not a functional accessory. Several products on the market already integrate photovoltaic panels with the lamp heads, achieving solar power supply while maintaining a simple appearance. For landscape light pillars with special design requirements, customized flexible PV modules or BIPV (building-integrated photovoltaics) technology can be used for integrated design.
Color Temperature and Color Rendering Index (CRI) Landscape axis lighting typically requires high-quality lighting environments. A color temperature of 3000K to 4000K is recommended, as a warmer light helps create a comfortable and pleasant pedestrian environment. A CRI of no less than 80 ensures accurate color reproduction of plants, paving, and building facades. This differs from road lighting, which emphasizes high brightness, and needs to be distinguished during selection.
Smart Lighting Interface Provision New city construction is often accompanied by the simultaneous development of smart city infrastructure. Solar streetlights should reserve wireless communication interfaces such as NB-IoT, LoRaWAN, or Zigbee to support remote monitoring, brightness adjustment, fault alarms, and energy consumption data collection. Determining communication protocols and data interface standards during the planning stage can avoid compatibility issues during later system integration.
V. Recommendations for a Multi-Departmental Collaborative Planning Process
In Uzbekistan's new city projects, achieving unified planning for photovoltaics and lighting requires the collaborative involvement of multiple professional teams, including urban planning, municipal engineering, landscape design, and electrical design.
It is recommended to introduce a specialized solar lighting consultant during the planning scheme design phase (rather than the construction drawing design phase) to participate in the coordination of road cross-section design, vegetation configuration, and building setbacks. The selection parameters and installation requirements for solar streetlights should be incorporated into the planning technical conditions as mandatory constraints for subsequent detailed design.
For new city projects developed in phases, it is recommended to reserve upgrade and expansion interfaces for the solar lighting system during the first phase of construction, including pre-embedded pipelines within the light poles, expansion space for the control system, and coverage of the communication network. This avoids infrastructure incompatibility issues discovered during the second phase of expansion after the first phase is completed.
The window of opportunity for new city construction in Uzbekistan is the best time to promote solar streetlights. Intervening from the planning stage is much more efficient, cost-effective, and efficient than retrofitting after construction.
