LONGi Solar Panels

LONGi Solar Panels for UK Installers

LONGi is a global Tier 1 solar manufacturer and one of the world’s leading producers of monocrystalline silicon wafers, solar cells and photovoltaic modules. Its products are supplied across more than 160 countries and are used in residential, commercial, industrial and utility-scale solar installations.

The LONGi range combines high module efficiency, durable construction and reliable long-term performance, making it suitable for a wide variety of UK solar PV projects.

Advanced Back-Contact Solar Technology

Selected LONGi solar panels use advanced N-type back-contact cell technology. By positioning the electrical contacts on the rear of the solar cell, the design reduces obstruction across the front surface and allows more of the cell area to receive sunlight.

This architecture supports high conversion efficiency, strong low-light performance and a clean appearance without conventional front-facing busbars. Full-black back-contact panels are particularly suited to visible residential rooftops, while higher-output and bifacial glass-glass modules provide options for commercial, industrial and larger-scale installations.

Full-Black and Bifacial LONGi Panels

Alternergy’s LONGi range may include full-black monofacial panels for residential rooftops and bifacial glass-glass modules for residential, commercial and industrial solar projects.

Bifacial modules can generate electricity from light reaching both the front and rear surfaces of the panel. The additional rear-side yield depends on the mounting configuration, installation height, surface reflectivity and overall system design.

High-Efficiency Solar Panels

High-efficiency LONGi modules allow installers to achieve greater generating capacity from a limited installation area. This can be particularly valuable on projects where usable roof space is restricted or where a higher array output is required from a fixed footprint.

Available specifications vary by model. Installers should check the relevant product page and technical datasheet for module efficiency, dimensions, weight, connector type, MCS certification and electrical characteristics.

LONGi Solar Panel Warranties

Selected LONGi solar panels are supported by product and linear performance warranties of up to 30 years. The exact warranty period and conditions vary by model, so the applicable product datasheet and manufacturer warranty document should be reviewed before specification or purchase.

LONGi Solar Innovation

LONGi continues to invest in next-generation photovoltaic research, including crystalline silicon–perovskite tandem cells and advanced back-contact solar technology. These developments reinforce the company’s position as a leading international solar manufacturer.

Research-cell efficiency records should not be confused with the efficiency of commercially available solar modules. Customers should refer to each product page for the rated module efficiency of the panel being purchased.
