Case Study: Thermos Solar Street Light Project in Israel

I. Project Background & Needs Analysis

1.1 Project Background

Israel is globally renowned for its high-tech industries and serves as a benchmark for renewable energy adoption. According to data from the Israeli Ministry of Energy, the country aims to generate 30% of its electricity from renewable sources by 2030, with solar energy playing a pivotal role.

Israel’s climate presents unique conditions: annual sunshine exceeds 3,000 hours, while summer temperatures can surpass 40°C (104°F). In contrast, winter seasons occasionally bring extended overcast and rainy periods. These conditions make Israel an ideal market for solar lighting systems, while simultaneously imposing stringent requirements on product durability and weather resistance.

This project is located in a high-end residential community in central Israel, covering approximately 50 hectares. The development includes multi-story apartments, high-rise residences, and expansive landscaped green spaces. The community features modern architectural styles accented by palm trees, manicured hedges, and lawns dotted with yellow flowers, creating a vibrant and livable urban oasis.

During an assessment of the existing lighting infrastructure, property management identified several issues with traditional grid-connected streetlights, including high energy consumption, frequent maintenance needs, and installation methods that disrupted the landscape. In response to the national “Green Israel” initiative, the community decided to upgrade to a solar street lighting system to reduce its carbon footprint while improving residents’ quality of life.

The project involves the installation of approximately 200 solar street lights across internal roads, walkways, and public activity areas, with the goal of building a “zero-carbon” smart community.

1.2 Core Requirements

Project requirements are shaped by Israel’s climate characteristics and the community’s functional and aesthetic expectations, with a strong emphasis on sustainability, intelligence, and long-term reliability. Key requirements include:

• Low-Carbon Sustainability
  The system must operate on 100% solar energy to eliminate fossil fuel dependence, in line with Israel’s renewable energy subsidy policies. High solar conversion efficiency is required to minimize energy loss.

• High-Temperature Tolerance
  Extreme summer heat exceeding 45°C demands stable battery and component performance under high temperatures, preventing thermal runaway and performance degradation.

• All-Weather Stability
  Although Israel enjoys abundant sunshine, winter conditions may include prolonged rainy periods. The lighting system must provide uninterrupted illumination for at least 10 consecutive rainy days, ensuring year-round reliability with zero outages.

• Installation Simplicity & Aesthetics
  Existing landscaped environments restrict large-scale excavation for cabling. Luminaire designs must be minimalist and modern, blending harmoniously with light-colored buildings, palm trees, and green spaces.

• Precision Management
  Remote monitoring and parameter adjustment capabilities are required to support fault diagnosis and reduce maintenance costs. Smart sensing features, such as PIR motion detection, are preferred to enable demand-based lighting and further energy savings.

These requirements prioritize not only technical performance but also long-term ROI (Return on Investment), making the solution replicable for similar residential and municipal projects.

II. Technical Solution Design

In response to the project’s requirements, SRESKY recommended the ATLAS Series integrated solar street lights. With brightness options ranging from 2,000 lm to 10,000 lm, the SRESKY ATLAS Series has been deployed in over 3,500 global tender projects, demonstrating proven reliability in diverse and demanding environments.

The solution design focuses on core technology integration and hardware optimization to ensure stable operation under Israel’s high temperatures and intense solar irradiation.

2.1 Core Technology Adaptation

The ATLAS Series integrates multiple patented technologies developed by SRESKY, specifically optimized for high-temperature and high-irradiance environments:

• TCS Temperature Control System
  Designed to address extreme summer heat, TCS continuously monitors battery temperature, supporting charging within a range of 0°C to 45°C and operation from –20°C to 60°C. Intelligent algorithms automatically regulate charging and discharging rates under high temperatures to prevent overheating and battery damage. Field testing shows that TCS extends battery lifespan by more than 30%, significantly exceeding the typical 1,500-cycle lifespan of standard lithium batteries.

• ALS 2.2 Core Technology
  During overcast or rainy conditions, ALS 2.2 dynamically adjusts output power to maintain consistent illumination. The system supports more than 10 days of continuous lighting during extended cloudy periods without compromising luminous efficacy. Advanced algorithms intelligently allocate stored energy, prioritizing essential lighting needs—an ideal solution for Israel’s occasional winter cloud cover.

• BMS Battery Management System
  The BMS improves charging efficiency by up to 30% and works in conjunction with high-performance lithium batteries to ensure efficient energy storage. It includes overcharge and overdischarge protection, as well as multi-level balanced charging, to maintain long-term battery health.

• Smart Sensing & Operating Modes
  An integrated PIR motion sensor (120° detection angle, maximum 8 m range) supports three preset lighting modes:

  • M1: 30% brightness with automatic boost upon motion detection until dawn, suitable for low-traffic areas.

  • M2: 100% brightness for the first 5 hours, followed by 25% brightness with PIR activation for the next 5 hours, then 70% brightness until dawn—balancing safety and energy efficiency.

  • M3: Constant 70% brightness throughout the night for high-traffic roads.

  In addition, the Super Remote Control allows property managers to customize parameters remotely, enabling seasonal or scenario-based optimization.

These technologies collectively enhance system adaptability, reduce energy consumption, and ensure compliance with EU and Israeli energy efficiency standards.

2.2 Hardware Specifications
