LONGi LR4-60HPB-350M 350W Half-Cut Mono PERC Solar Panel

The LONGi LR4-60HPB-350M 350W Half-Cut Mono PERC Solar Panel is designed for dependable solar energy generation in residential, commercial and industrial applications. Featuring monocrystalline PERC cell technology and a half-cut cell design, this solar module offers a rated power output of 350W and module efficiency of up to 19.2%.

For homeowners, businesses and solar project installers in Bangladesh, the LONGi 350W solar panel can be considered for rooftop solar installations, backup power systems and other photovoltaic applications. Its electrical specifications make it important to select compatible solar charge controllers, inverters and protection devices according to the system design.

Half-Cut Mono PERC Technology

The LR4-60HPB-350M combines monocrystalline solar cells with PERC technology and a half-cut cell configuration. This design is intended to support efficient energy conversion and reliable module performance.

With a rated maximum power output of 350W under standard rating conditions, the panel can contribute to different solar system capacities. The total number of panels required depends on the target system size, available installation space, daily energy demand and solar conditions at the installation site.

Electrical Performance and Compatibility

The LONGi LR4-60HPB-350M has an open circuit voltage (Voc) of 37.7V and a short circuit current (Isc) of 11.16A. At maximum power, it operates at a voltage of 34.4V and a current of 10.18A.

Its maximum system voltage is rated at 1000V DC, with a maximum series fuse rating of 20A. These specifications should be considered when designing solar panel strings and selecting compatible equipment.

Before installation, confirm the charge controller's maximum PV input voltage, operating voltage range, current capacity and supported solar power. For inverter-based systems, verify the manufacturer's requirements for string voltage, current and maximum PV input power.

Durable Construction for Solar Installations

This LONGi solar panel measures 1755 × 1038 × 35mm and weighs 19.5kg. Its construction includes 3.2mm coated tempered glass and an anodized aluminium frame.

The module also features an IP68-rated junction box. Its stated mechanical load ratings are 5400Pa on the front side and 2400Pa on the rear side. These specifications can help installers assess the panel's suitability for a project, but the mounting structure and installation method must still meet site-specific requirements.

The stated operating temperature range is -40°C to +85°C. Actual power generation will vary with sunlight intensity, panel orientation, shading, temperature and other environmental factors.

Warranty and Long-Term Performance

The supplied product information specifies a 12-year product warranty and a 25-year linear power performance warranty. Buyers should review the applicable warranty documentation to confirm coverage, exclusions, degradation terms and the conditions for making a claim.

The stated power tolerance is 0 to +5W, indicating a positive tolerance above the rated 350W output according to the supplied specifications.

Applications in Bangladesh

The LONGi LR4-60HPB-350M can be considered for residential rooftop systems, small commercial installations, office buildings, shops and other solar projects where its electrical characteristics and physical dimensions are suitable.

For off-grid systems, the panel may be used with a compatible solar charge controller and battery bank. For on-grid or hybrid applications, compatibility with the selected inverter must be confirmed before installation.

When purchasing a LONGi 350W solar panel from Muthobd.com, check the product's availability, warranty documentation and installation requirements before finalizing your system design. Proper equipment selection and professional installation help support safe operation and dependable solar energy generation.
