Power One Engineering Ltd

Solar System

In the electrical engineering industry, we specialize in the design, installation, and maintenance of high-performance solar solutions.

Solar Panel (LONGi / JA / Jinko / Canadian Solar)

Solar panels are the heart of any solar power system, converting sunlight into usable DC electricity. We supply and install premium-quality solar panels from globally trusted brands like LONGi, JA Solar, Jinko, and Canadian Solar, ensuring strong performance and long-term durability in Bangladesh weather conditions. Our team helps you choose the correct panel type and wattage based on your available rooftop or shed space, daily energy usage, and budget. We ensure proper panel layout planning to avoid shading issues, maximize sunlight exposure, and maintain safe spacing for cleaning and maintenance. We use reliable mounting structure design with proper angle selection, wind load support, and corrosion-resistant fittings for long service life. A high-quality panel setup reduces long-term degradation and ensures stable energy generation throughout the year. Whether your goal is reducing monthly electricity bills or ensuring backup support for critical loads, our panel solutions are designed for maximum output, safety, and reliability. We also guide you on warranty, performance expectations, and future expansion opportunities so your investment remains valuable for years.

Inverter (Hybrid / On-Grid / Off-Grid) (Huawei / Growatt / Sungrow / Sunway)

The inverter is the brain of your solar system, converting DC power from solar panels into usable AC power for your home, office, or factory. We provide solar inverter solutions based on your exact requirement: On-Grid for maximum bill savings, Off-Grid for full backup independence, and Hybrid systems for a balanced combination of savings and battery backup. We install reliable inverter brands like Huawei, Growatt, Sungrow, and Sunway, ensuring stable performance, high efficiency, and safe operation. Our service includes proper inverter sizing, load distribution planning, protection setup, and installation with all electrical safety standards. We also configure monitoring features so you can track generation, consumption, and system health in real-time. A properly installed inverter protects your system from over-voltage, overload, and abnormal grid conditions. We ensure clean wiring, correct earthing, surge protection integration, and commissioning tests before final handover. With the right inverter setup, your solar system becomes smarter, safer, and more efficient for long-term energy management.

Battery, Structure and Fitting Accessories

A complete solar solution is not only about panels and inverters—battery systems, mounting structures, and accessories play a critical role in system reliability and safety. We provide full solar support components including solar batteries (for backup power), mounting structures, DC/AC cables, MC4 connectors, junction boxes, isolator switches, and safety breakers. For battery-based systems, we ensure proper battery sizing based on your backup hour requirement and critical load needs, while maintaining safe charging and discharge performance. We install durable solar mounting structures designed for rooftops and sheds, ensuring strong load capacity, correct tilt angle, anti-rust finishing, and protection against wind or heavy rain. Our accessories setup includes cable management, protective conduits, fuses, SPD, and earthing to minimize electrical risk and improve long-term safety. Proper fitting accessories reduce voltage drops, improve system efficiency, and prevent overheating issues caused by poor-quality materials. We focus on using reliable components so your solar system remains stable, efficient, and low-maintenance. This ensures your investment delivers consistent energy output and long service life.
