Its headline output is **690 W** with a listed module efficiency of **25.54%**. 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 ManufacturerLONGi SolarModel / item codeLR7-72HJD-690MPanel technologyN-type HIBC back contactPower output690 WModule efficiency25.54%Cell count144FinishAnodised aluminium alloy frameDimensions (W × H × D)1134 mm × 2382 mm × 30 mmWeight32.5 kgManufacturing originChinaListed degradation / durability1% first year, 0.35% per year from year 2 to 30 ### 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/longi-solar-lr7-72hjd-665m.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? Hi-MO S10 LR7-72HJD-690M may suit a industrial 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 NameHi-MO S10 LR7-72HJD-690MManufacturerLONGi SolarWattage690 WEfficiency25.54%Cells144Cell typeN-type HIBC back contactColourAnodised aluminium alloy frameMade inChinaWidth1134Height2382Weight32.5 Shop ## Shop [![LONGi Solar Hi-MO S10 LR7-72HJD-665M](/images/panels_resolved/longi-himo-6-explorer-585w/320.webp) £108.40LONGi Solar Hi-MO S10 LR7-72HJD-665M View product](/shop/kilowatts-uk/panel-longi-solar-lr7-72hjd-665m-206/)[![Astronergy ASTRO N7 Pro 670W](/images/panels/astronergy-chsm66rn-dg-f-bq-645.jpg) £109.21Astronergy ASTRO N7 Pro 670W View product](/shop/kilowatts-uk/panel-astronergy-chsm66rn-dg-f-bq-670/)[![Bauer Solar Glass-Glass Black Back Contact 480 W](/images/panels/bauer-solar-bs-480-108m10bcbb-gg.jpg) £78.24Bauer Solar Glass-Glass Black Back Contact 480 W View product](/shop/kilowatts-uk/panel-bauer-solar-bs-480-108m10bcbb-gg/)
