Its headline output is **505 W** with a listed module efficiency of **22.7%**. Use this page as a practical starting point for comparing generation, roof space, installation constraints and whole-system value; the panel alone does not determine the annual yield of an array. ### Specification at a glance ManufacturerTCL SolarModel / item codeHSM-ND54-DR505Panel technologymodule technologyPower output505 WModule efficiency22.7%Cell countNot statedFinishstandard frame finishDimensions (W × H × D)1134 mm × 1961 mm × 30 mmWeightNot statedManufacturing originNot stated in the catalogueListed degradation / durabilityNot stated in the catalogue ### What the figures mean The wattage is the panel’s rated output under standard test conditions, while efficiency describes how much of the available sunlight is converted within the module area. Higher efficiency can be useful where roof space is limited, but the best choice also depends on price, inverter sizing, cable runs, roof loading, access and the expected generation profile. Actual UK production varies with orientation, pitch, shading, temperature, soiling and clipping. ### Roof planning and installation Before specifying this module, measure the usable roof area rather than the overall roof. Allow room for edge clearances, access, mounting rails, cable routing and any roof windows or vents. The listed dimensions and weight should be checked against the installer’s structural assessment and lifting plan. Confirm that the proposed inverter, optimisers, isolators and protection equipment accept the panel’s electrical range; do not select a panel from wattage alone. For a residential roof, compare the module footprint with the number of panels needed. For commercial or industrial work, also consider wind exposure, loading zones, maintenance walkways and future access. ### Performance and value A panel with a strong nameplate rating can reduce the number of modules required for a target system size, but yield is a system-level result. Ask for an annual generation estimate based on the site postcode, roof orientation and shading survey. Compare like-for-like quotations that identify the exact module, inverter, mounting system, monitoring, commissioning and warranty terms. A slightly lower-wattage module may offer better value if it fits the roof more efficiently or avoids an expensive structural alteration. ### What to confirm before ordering - Exact model and item code match the quotation and datasheet. - Panel dimensions, weight and finish suit the roof and planning requirements. - Electrical compatibility is confirmed with the chosen inverter and string design. - Warranty, degradation wording and installation workmanship cover are supplied in writing. - Delivery, storage, lifting and replacement-panel arrangements are included in the project plan. [View the available manufacturer or datasheet information](/images/panels/sheets/tcl-solar-hsm-nd54-dr485.pdf). Specifications can change between production batches, so the installer should verify the current document before final design. ### Is this panel right for your project? TCL Solar T-Class 505 W may suit a commercial installation where its output, efficiency and physical format align with the roof and system design. Request a site-specific quote to check yield, string voltage, mounting, grid requirements and the installed price before committing. ## Specifications NameTCL Solar T-Class 505 WManufacturerTCL SolarWattage505 WEfficiency22.7%Cells0Width1134Height1961Weight0 Shop ## Shop [![Ulica Solar Black Jade Flow 505 W](/images/panels/ulica-solar-ul-470m-108ddgn.jpg) £82.32Ulica Solar Black Jade Flow 505 W View product](/shop/kilowatts-uk/panel-ulica-solar-ul-505m-108ddgn/)[![GCL System Integration NT12R/54GDF 505 W](/images/panels/gcl-system-integration-nt12r-54gdf-505.jpg) £82.32GCL System Integration NT12R/54GDF 505 W View product](/shop/kilowatts-uk/panel-gcl-system-integration-nt12r-54gdf-505/)[![DAS Solar DAS-DH108NE 505W](/images/panels/das-solar-das-dh108ne-500.jpg) £82.32DAS Solar DAS-DH108NE 505W View product](/shop/kilowatts-uk/panel-das-solar-das-dh108ne-505-111/)
