LONGi LR4-60HPB-355M 355W Half-Cut Monocrystalline Solar Panel

LONGi LR4-60HPB-355M 355W Half-Cut Mono Solar Panel

The LONGi LR4-60HPB-355M 355W Half-Cut Mono Solar Panel is designed for reliable solar energy generation in residential, commercial and industrial applications. Featuring monocrystalline half-cut cell technology, this module delivers a rated maximum power output of 355W and a stated module efficiency of up to 20.6%.

For homeowners, businesses and solar installers in Bangladesh, the LONGi 355W solar panel can be considered for rooftop solar systems, commercial buildings and other photovoltaic installations. Its electrical ratings and physical construction make it important to select compatible inverters, charge controllers, mounting structures and protection devices.

Half-Cut Monocrystalline Solar Technology

The LR4-60HPB-355M uses half-cut monocrystalline solar cell technology to support efficient electricity generation. With a rated output of 355W, it can contribute to different solar system capacities depending on the number of modules installed and the project's energy requirements.

When planning a solar installation, consider available roof space, daily electricity consumption, sunlight conditions, shading and the required system capacity. Actual energy production varies with installation orientation, temperature and local weather conditions.

Electrical Performance and Compatibility

The LONGi LR4-60HPB-355M has a voltage at maximum power (Vmp) of 34.6V and a current at maximum power (Imp) of 10.27A. Its open circuit voltage (Voc) is 40.6V, while its short circuit current (Isc) is 11.25A.

The panel supports a maximum system voltage of 1000V DC and has a maximum series fuse rating of 20A. These ratings are important when calculating solar string configurations and selecting compatible electrical equipment.

The module may be integrated into appropriately designed on-grid, off-grid or hybrid solar systems. Before installation, verify the inverter or charge controller's PV input voltage range, maximum current, total allowable solar capacity and other manufacturer requirements.

Durable Construction for Outdoor Installation

This solar panel measures 1755 × 1038 × 35mm and weighs 19.5kg. Its anodized aluminium alloy frame provides structural support, while the IP68-rated junction box offers protection against dust and water ingress under the applicable rating conditions.

The supplied specifications list a front-side mechanical load rating of 5400Pa and a rear-side rating of 2400Pa. These ratings can help installers assess the module for a project, but the mounting structure must be engineered for the actual site conditions and applicable building requirements.

The specified operating temperature range is -40°C to +85°C, supporting consideration for outdoor installations across a variety of environmental conditions.

Warranty and Long-Term Performance

The supplied product information states a 12-year product warranty and a 25-year linear power performance warranty. It also specifies first-year power degradation of less than 2%. Buyers should check the official warranty documents to confirm the precise degradation schedule, exclusions and applicable claim conditions.

The stated power tolerance is 0 to +3%, indicating a positive power tolerance above the rated output according to the supplied specifications.

Applications in Bangladesh

The LONGi LR4-60HPB-355M may be suitable for residential rooftops, shops, offices, small commercial buildings and other solar projects where its output and electrical characteristics match the system design.

For battery-based systems, use a compatible charge controller and battery configuration. For on-grid and hybrid installations, confirm inverter compatibility and ensure that string voltage and current remain within the manufacturer's limits.

When purchasing the LONGi 355W solar panel from Muthobd.com, confirm availability, warranty documentation and installation requirements before finalizing your order. Proper system design and professional installation help support safe operation and dependable solar power generation.
