Premium engineered systems configured for maximum operational efficacy, built to withstand winter snow loads and coastal humidity in Bulgarian municipalities.
Under the European Green Deal and Bulgaria's updated National Energy and Climate Plan (NECP), municipalities from Sofia to Varna are facing strict carbon reduction targets and escalating electricity tariffs. Traditional street grid networks are not only maintenance-intensive but also vulnerable to systemic blackouts and voltage fluctuations.
Integrated (All-in-One) solar street lights represent a major paradigm shift. By housing high-efficiency monocrystalline solar panels, LiFePO4 batteries, MPPT (Maximum Power Point Tracking) smart controllers, and high-lumen Bridgelux or Philips LED chips in a single, structurally sound aluminum alloy casing, these systems completely bypass the grid. There is no trenching, no underground cable laying, and no electrical utility dependency.
This allows Bulgarian industrial parks, logistics bases in Plovdiv, and remote municipalities in the Rhodope Mountains to install dependable public safety lighting at a fraction of the capital expenditure (CAPEX) and near-zero operating expenses (OPEX).
Bulgaria presents a unique meteorological profile: freezing winter temperatures (dropping to -15°C in regions like Pleven and Sofia) combined with heavy snow load accumulation, followed by intense summer heat up to +40°C in the South. Standard solar lights often fail due to lithium battery freezing, leading to rapid degradation or complete operational shutdown during critical winter weeks.
Our solutions for the Bulgarian market utilize advanced low-temperature formulations of Lithium Iron Phosphate (LiFePO4) batteries coupled with smart Battery Management Systems (BMS). The BMS dynamically modulates charging rates and thermal conditions, ensuring the battery charges safely during cold days. Coupled with IP66 and IP67 weather sealing and adjustable panel angles, our systems maximize solar irradiance conversion even on short, overcast winter days.
Luminaires designed to meet European road lighting classes with optimized optical distribution patterns.
Specialized BMS configurations designed to protect cells and support charging at -20°C winter conditions.
Anodized aluminum alloy and marine-grade anti-corrosive coatings for Black Sea coastal installations.
Optional LoRaWAN and NB-IoT protocols integrated for remote municipal control and real-time status monitoring.

The global solar lighting market has transitioned from low-cost, basic luminaires to high-performance, long-lasting capital equipment. Meeting the standard criteria for municipal tenders in the EU requires structural precision and reliable electronics that cannot be built through manual assembly processes.
Yangzhou, China represents the epicenter of global street pole and solar lighting manufacturing, clustering critical raw materials, LED engineering centers, and automated manufacturing parks. Yangzhou OneAll Lights Co., Ltd. capitalizes on this unique geographic concentration by utilizing vertically integrated production. Rather than outsourcing component sourcing, we perform critical steps in-house: from CNC bending and automatic submerged arc welding of structural components to automated SMT board placement, wave soldering, and environmental aging tests.
For Bulgarian developers, this localized cluster translates to a reliable supply chain, shorter lead times, strict cost control, and the engineering agility required to support deep OEM/ODM customizations.
When drafting municipal or private sector tenders for solar street lighting in Bulgaria, engineers must look beyond nominal LED wattage. Focus instead on these system design parameters:
Luminous Efficacy: Focus on lumens per watt (lm/W) rather than battery capacity alone. High efficacy LEDs (160lm/W–180lm/W) deliver equivalent illumination levels while drawing up to 40% less battery energy, lowering overall system weight and pole load.
MPPT Charging Efficiency: Unlike cheaper PWM controllers, Maximum Power Point Tracking (MPPT) controllers track the optimal operating voltage of the solar panel in real-time, increasing charging efficiency by 15% to 30%, which is essential under Bulgaria's variable winter cloud cover.
Autonomy Days: Quality integrated lights must guarantee at least 3 to 5 continuous rainy or overcast days of operations through intelligent dimming algorithms (PIR/microwave sensors combined with customized time-zone dimming profiles).
Engineered configurations built to address local regulatory, environmental, and spatial requirements across Bulgaria.
High-power integrated solar lamps, such as our 600W and 1200W models, provide bright, perimeter-wide illumination for freight yards and warehouse borders without high trenching and cabling costs.
Coastal roads demand marine-grade protection. Our storm-proof IP66 die-cast aluminum models feature salt-mist resistant polyester powder coatings to protect internal electronics against saltwater air.
For village connecting roads and public spaces where grid extensions are too costly, integrated lights with smart PIR motion sensors provide reliable illumination on demand, preserving battery life.
