Author Yangzhou Shanhong New Energy Development Co., Ltd. Source basis First-party model documents and editorial selection guidance Direct answer Compare output and physical format as one design decision. Rated power identifies the output class, efficiency describes the proportion of incident solar power converted to electrical output under the stated test conditions, dimensions determine the footprint, and weight affects structure and handling. None of the four confirms project fit alone. The relationship The numbers answer four different questions. A high headline wattage can come with a larger physical format. A compact module can fit a constrained roof differently. The comparison only becomes meaningful after the project constraint is named. Power: how much rated output is listed? Use the published range to identify output classes within the exact model. It does not predict annual energy yield or confirm current availability. Efficiency: how much incident solar power becomes electrical output? Module efficiency is the ratio of electrical output power to incident solar power (irradiance × total module area) under the stated test conditions. It is not annual energy yield. Dimensions: how much physical space does one module occupy? Length and width affect row count, roof coverage, setbacks, access paths, mounting geometry and transport planning. Weight: what does each unit add to structure and handling? Module weight belongs in structural and installation review. Compare both weight per module and the number of modules required by the system concept. Published Sunhorn snapshot The same four fields reveal different module formats. The table is a factual starting point from the currently published English datasheets, not a ranking. Data table · How should power, efficiency, size and weight be compared together? Model Power range Maximum efficiency Dimensions Weight SH18-54H-D 425–445W 22.8% 1722 × 1134 × 30 mm 21.5 kg SH21R-48H-D 435–455W 22.8% 1762 × 1134 × 30 mm 21 kg SH21R-192H-D 460–485W 24.27% 1762 × 1134 × 30 mm 24.4 kg SH18-72H-D 570–590W 22.8% 2278 × 1134 × 30 mm 30.5 kg SH21R-66H-D 605–625W 23.2% 2382 × 1134 × 30 mm 32.5 kg SH21R-264H-D 650–670W 24.80% 2382 × 1134 × 30 mm 32.5 kg SH21-66H-D 690–710W 22.8% 2384 × 1303 × 35 mm 38.5 kg Three project lenses Start from the constraint, then return to the datasheet. The same module can be evaluated differently when the primary constraint changes. Space-constrained roof Review usable area, obstructions, setbacks and access first. Efficiency and module dimensions become especially relevant, but electrical design and mounting still require the complete specification. Handling-constrained installation Review access, lifting method, crew plan and module weight. Fewer high-power modules may change handling and layout without automatically simplifying installation. Large project or repeated layout Consider how module format, string design, mounting repetition and logistics interact across the whole system. A per-module comparison is only the beginning. Comparison checklist Record the same evidence for every candidate. A consistent comparison sheet prevents one attractive number from changing the criteria halfway through the review. Fix the project assumptions Record application, available area, mounting approach, electrical concept and handling constraints. Use exact model codes Keep series, model and power range together in every row of the comparison. Copy fields from one revision Record the datasheet language and revision so every value remains traceable. Compare the four fields together Review power, efficiency, dimensions and weight against the same project assumptions. Complete the engineering review Check electrical, mechanical, certification and warranty requirements in the full documents. Confirm current commercial conditions Use the enquiry to confirm availability, order requirements, destination and current terms. Frequently asked questions Questions about comparing module specifications. Does higher wattage always mean a better module? No. Higher wattage identifies a higher output class, but the module format, efficiency, weight, electrical characteristics and project conditions still determine fit. Is the highest efficiency always best for a roof? No. Efficiency can matter when space is constrained, but usable layout, dimensions, structure, mounting and system design must also be reviewed. Can published values confirm the final selection? No. They support a shortlist. Final selection requires the exact current documents and project-specific technical and commercial confirmation.

A datasheet is not a product ranking. It is the model-specific source used to verify electrical, mechanical and warranty information against the conditions of a real project. Author Yangzhou Shanhong New Energy Development Co., Ltd. Source basis First-party model documents and editorial selection guidance Direct answer Start with the exact model code, then read the fields as one connected specification. Confirm the series, model and published power range first. Then check efficiency, dimensions, weight and the complete electrical, mechanical, warranty and certification sections in the corresponding PDF. A single number should never replace the full project review. Step 1 · Identify the document Three identifiers must stay together. Series names help navigation, but technical review must remain attached to the exact model and its published wattage range. Series Use it to locate the product family. HISEER 4N, 5N, 6N and 7N organize the current Sunhorn portfolio, but one series can contain more than one model and product direction. Exact model Treat the model code as the primary reference. Codes such as SH21R-66H-D and SH21R-264H-D are different products. Keep the full code in technical notes, comparisons and enquiries. Power range Read a range as a published range. Do not turn the highest value into a universal output claim. Use the range to identify the listed model, then review the exact PDF. Step 2 · Read connected fields No single field decides project fit. The following fields answer different questions. Read them together and compare them with the project design rather than using one headline value as a shortcut. Power range Helps identify the published output classes available within the model range. It does not confirm stock, project yield or suitability by itself. Maximum module efficiency Supports comparison of a published datasheet field, but must be considered with module format, system design and operating conditions. Dimensions Connect the module footprint to roof or site layout, mounting design, access, spacing and installation planning. Weight Use the model weight in structural, handling and installation review. Do not assume similar wattage means similar physical format. Warranty information Read the product and linear power warranty fields in the exact PDF and keep them separate from current commercial terms. Document source and language Use the current official PDF for the exact model and the language required by the project team. Avoid copying technical values from an unrelated series. Electrical review Read the operating point, limits and test conditions together. Power alone does not describe how a module connects to an inverter or behaves when temperature and irradiance change. Voltage and current at the maximum power point Vmp and Imp describe the voltage and current at the maximum-power point under the stated test conditions. Use both values when checking the intended string design and inverter operating window. Open-circuit voltage and short-circuit current Voc is the voltage with the output open-circuited; Isc is the current with the output short-circuited, under the stated test conditions. Apply the relevant temperature and irradiance corrections in design; these are not fixed upper limits or maximum-power operating values. Temperature coefficients Temperature changes voltage, current and power. Read the published coefficients with the project temperature assumptions instead of treating standard test values as all-weather output. System and protection limits Check maximum system voltage, maximum series fuse rating and other module limits in the exact datasheet against the system architecture and applicable engineering requirements. Test conditions and tolerance Distinguish standard test conditions (STC), conditions associated with nominal operating cell temperature (NOCT) or nominal module operating temperature (NMOT), and any bifacial test conditions stated in the document. Check tolerances separately; do not treat these conditions or temperature indicators as interchangeable. Mechanical and document review A technically suitable module must also fit the site, mounting plan and document requirements. This part of the review turns a product comparison into an installation and procurement check. Module format and layout Use length, width and frame thickness to test row spacing, roof coverage, access routes, clamps and mounting geometry. Similar power classes can have materially different footprints. Weight and handling Connect module weight to structural review, lifting, on-site movement and installation method. A higher-power module can reduce module count while increasing the handling burden per unit. Loads, frame and mounting zone Check the published mechanical-load information and permitted mounting method for the exact model. Do not transfer a load value or clamp position from another module. Cable, connector and junction-box details Review cable length, connector and junction-box information alongside the electrical layout. Confirm compatibility through the project technical process rather than assuming components are interchangeable. Warranty, certification and revision Record the datasheet revision and verify required certificates and warranty documents separately. A datasheet summary does not replace the complete current documents required by the destination market. Step 3 · Apply a review sequence Move from project conditions to document verification. This sequence keeps the shortlist connected to the installation, electrical design and purchasing context. Define the application Record whether the project concerns a rooftop, commercial and industrial system, ground-mounted plant or another published application context. Set the target range Use the required power range and market direction to form an initial shortlist without declaring a winner. Match the exact model Keep the series, model code and power range together when opening the PDF and recording the comparison. Check mechanical fit Review dimensions and weight against layout, mounting, structure, access and handling requirements. Complete the technical review Use the full PDF for the electrical, mechanical, warranty and certification fields required by the project team. Submit the enquiry context Provide the selected model, application, order requirements and destination for current availability and commercial terms.

A defensible comparison preserves model identity, source context and the boundary between published technical information and project-specific confirmation. Comparing series names without model codes A series is a navigation layer, not a substitute for the exact product reference. Using maximum wattage as the whole specification The upper end of a range does not describe dimensions, weight, electrical fields or project fit. Treating efficiency as a universal ranking Efficiency is one published field and should not erase format, system design or installation conditions. Mixing technical data with availability or price The datasheet identifies the product. Current availability and commercial terms belong to the project enquiry. Frequently asked questions Questions about reading photovoltaic module datasheets. Can the highest efficiency value identify the best module? No. Maximum efficiency is one comparison field. Model selection must also consider dimensions, weight, the complete electrical and mechanical specification, installation conditions and project requirements. Can two models in the same series be treated as the same product? No. Keep the exact model code and published power range with every technical reference and open the corresponding PDF. Does a datasheet confirm current availability or price? No. The datasheet is the technical source for the model. Availability and commercial terms are confirmed for the selected model, order requirements and destination. Start a Conversation Review the exact model with the project context attached.

Next step View product page View product page Before comparing products Write the project brief before choosing the product direction. The choice becomes clearer when the team agrees on the installation, electrical and procurement constraints first. Installation format and usable area Record whether the project is a residential roof, distributed commercial roof, industrial site or ground-mounted plant. Include usable area, obstructions, setbacks, access paths and the intended mounting geometry. Target output and electrical concept Define the target power class, preliminary string concept and inverter operating window. The listed wattage range is a shortlist filter, not a substitute for voltage, current and temperature review. Structure, handling and logistics Confirm module format, weight, lifting access, crew handling and transport constraints. A higher-power module may reduce unit count while changing the physical demands of installation. Destination documents List the datasheet language, certificates, warranty documents and other current materials required by the destination market and project team. Published model evidence Compare exact models, not only the labels “all-black” and “4-split”. The four published European-direction models occupy different power and physical ranges.

Keep every conclusion connected to the exact model, project conditions and current source documents. Treating appearance as the complete rooftop decision The all-black direction can support visual integration, but layout, structure, electrical design and the exact datasheet still determine technical fit. Assuming higher wattage is universally better The 650–670W range represents a different module format and direction. Compare dimensions, weight and system design rather than ranking wattage alone. Comparing series without model codes HISEER 4N contains three listed European-direction models. Retain the full model code and power range in every technical note and enquiry. Mixing technical selection with current availability The website and datasheet support technical review. Availability, destination requirements and commercial terms must be confirmed for the specific enquiry. Selection sequence Choose from project conditions—not from a generic ranking. The two directions are not presented as universally better or worse. Start with the installation and electrical design, then verify the exact model datasheet. 01 Define the installation format Clarify whether the project is a residential or distributed rooftop, an industrial application or a utility-scale plant. 02 Set the target power range Compare the listed 425–485W HISEER 4N range with the 650–670W SH21R-264H-D range. 03 Review the model datasheet Use the corresponding datasheet to check the exact model against the project's electrical and installation requirements. 04 Request project-specific confirmation Contact Sunhorn to confirm availability and commercial terms for the selected model and destination. Direct answer Which Sunhorn module should a European buyer consider? Consider HISEER 4N when the project calls for one of Sunhorn's listed all-black formats in the 425–485W range. Consider SH21R-264H-D when the project calls for the listed HISEER 6N 4-split architecture and a 650–670W power range. Final selection depends on the project's technical requirements. Frequently asked questions Questions about selecting Sunhorn modules for Europe. Which Sunhorn modules are currently prioritized for Europe? Sunhorn currently prioritizes the HISEER 4N all-black range—SH18-54H-D, SH21R-48H-D and SH21R-192H-D—and the HISEER 6N 4-split SH21R-264H-D for Europe. Is an all-black module always a better choice than a 4-split module? No. All-black describes appearance, while 4-split is a published product design designation; the concepts are not opposites. Compare the exact listed HISEER 4N and HISEER 6N models against the installation, power range, electrical design and datasheet. How can a European buyer request a quotation?

View datasheets Before requesting terms A useful quotation starts with a complete procurement brief. The model and destination are necessary, but the technical and order context determines whether the quotation can support a real decision. Application and installation State whether the request concerns distribution stock, a commercial and industrial roof, a ground-mounted project or another defined application. Include site and mounting constraints that affect model fit. Exact model or target range Provide the complete model code when known. If the model is not fixed, provide the target power range and the project conditions used to build the shortlist. Order and destination information Record order requirements, delivery destination and the documentation required by the buyer. These inputs belong to the commercial enquiry rather than the public datasheet. Technical documents to review Identify the datasheet language, electrical and mechanical fields, warranty documents and certificates that the project team must verify before approval. Published model evidence The three options differ in power, efficiency, format and weight. Use these published fields to structure the shortlist, then open the exact PDF for electrical, mechanical, warranty and certification review. Data table · How to shortlist standard photovoltaic modules for a Brazilian project.

Sunhorn does not rank buyer types. Each buyer should connect the same published model information to its own operating requirements. Distributor or importer review Confirm which model and documents the intended market requires, then provide order and destination details for current terms. A broad power category is not a substitute for the exact product reference. Commercial and industrial project review Connect the candidate model to usable roof area, structure, mounting, electrical design, access and handling before comparing the commercial proposal. EPC or project-owner review Keep design assumptions, required documents and commercial responsibilities visible in the same review so that technical approval and purchasing refer to one model revision. Common procurement errors Four shortcuts weaken price and product comparisons. A defensible purchase keeps technical fit, document revision and current commercial conditions separate but connected. Requesting a price without an exact model or range A useful quotation needs a model context, order requirements and destination. Otherwise different products or assumptions may be compared as if they were equivalent. Choosing only by the highest wattage The 690–710W model is also the largest and heaviest of the three published options. Layout, structure and handling must remain part of the review. Using an unrelated datasheet Keep the complete model code with every copied field. Similar series names or power classes do not make technical documents interchangeable. Treating a past quotation as a public fixed price Commercial terms depend on the selected model, order requirements, destination and current conditions. Reconfirm them for each specific enquiry. Evaluation sequence Evaluate technical fit before comparing the current commercial terms. This keeps a cost-conscious procurement decision tied to the actual project instead of an isolated module price. 01 Project type and installation Define the application and installation conditions that the module must satisfy. 02 Model and power range Match the listed power range with the exact HISEER model under review. 03 Datasheet review Verify the technical and installation information in the corresponding datasheet. 04 Current quotation Request commercial terms for the model, order requirements and destination. About module pricing Why does Sunhorn not publish a fixed photovoltaic module price?

Source basis First-party model documents and editorial selection guidance Before requesting terms A useful quotation starts with a complete procurement brief. The model and destination are necessary, but the technical and order context determines whether the quotation can support a real decision. Application and installation State whether the request concerns distribution stock, a commercial and industrial roof, a ground-mounted project or another defined application. Include site and mounting constraints that affect model fit. Exact model or target range Provide the complete model code when known. If the model is not fixed, provide the target power range and the project conditions used to build the shortlist. Order and destination information Record order requirements, delivery destination and the documentation required by the buyer. These inputs belong to the commercial enquiry rather than the public datasheet. Technical documents to review Identify the datasheet language, electrical and mechanical fields, warranty documents and certificates that the project team must verify before approval. Current listed options Three published power ranges for the initial shortlist. The power range is an initial filter only. The corresponding datasheet and project conditions determine the final model selection.

Sunhorn does not rank buyer types. Each buyer should connect the same published model information to its own operating requirements. Distributor or importer review Confirm which model and documents the intended market requires, then provide order and destination details for current terms. A broad power category is not a substitute for the exact product reference. Commercial and industrial project review Connect the candidate model to usable roof area, structure, mounting, electrical design, access and handling before comparing the commercial proposal. EPC or project-owner review Keep design assumptions, required documents and commercial responsibilities visible in the same review so that technical approval and purchasing refer to one model revision. Common procurement errors Four shortcuts weaken price and product comparisons. A defensible purchase keeps technical fit, document revision and current commercial conditions separate but connected. Requesting a price without an exact model or range A useful quotation needs a model context, order requirements and destination. Otherwise different products or assumptions may be compared as if they were equivalent. Choosing only by the highest wattage The 690–710W model is also the largest and heaviest of the three published options. Layout, structure and handling must remain part of the review. Using an unrelated datasheet Keep the complete model code with every copied field. Similar series names or power classes do not make technical documents interchangeable. Treating a past quotation as a public fixed price Commercial terms depend on the selected model, order requirements, destination and current conditions. Reconfirm them for each specific enquiry. Before an enquiry Use the same factual checks for distribution and project sourcing. The website does not rank customer types or publish a universal low-price claim. Each enquiry is reviewed against its selected model and destination. 01 Define the application State whether the request concerns distribution stock or a specific commercial and industrial project. 02 Shortlist the model Match the project with the listed 570–590W, 605–625W or 690–710W power range. 03 Verify the datasheet Review the published datasheet for the exact model before submitting requirements. 04 Request current terms Provide order requirements and destination so Sunhorn can prepare a current project quotation. Direct answer Which Sunhorn modules can a Brazilian buyer start with? The current published shortlist is HISEER 5N SH18-72H-D at 570–590W, HISEER 6N SH21R-66H-D at 605–625W and HISEER 7N SH21-66H-D at 690–710W.

Comparison only becomes useful after the project constraint is defined. Power: what nominal output is listed? Use the published range to identify exact model classes. It does not predict annual yield or confirm availability. Efficiency: how much incident solar power becomes electrical output? Module efficiency is the ratio of electrical output power to incident solar power (irradiance × total module area) under the stated test conditions. It is not annual energy yield. Dimensions: how much physical space does one module occupy? Length and width affect modules per row, coverage, setbacks, access, mounting and transport. Weight: what load does each unit add? Weight belongs in structural and installation review. Compare unit weight together with the quantity required by the system.

Efficiency is one field Maximum efficiency helps compare the published datasheet fields, but it does not decide the best model for every roof, system design or operating condition. Dimensions and weight need a fit check Confirm roof layout, mounting design, handling plan and structural requirements against the exact model PDF. Power range is not availability A listed wattage range identifies the published model; current availability, order requirements and destination belong in the project enquiry. The PDF remains the technical source Use the exact datasheet for the full electrical, mechanical, warranty and certification fields needed by the project team. Comparison workflow Move from a broad shortlist to one controlled project record. The matrix is most useful when every step keeps the exact model, document revision and project assumption together. 1. Name the project constraint Start with usable area, target output, module format, structural limits, handling access, destination and required documents. Without a named constraint, a higher number can be mistaken for a better project fit. 2. Retain the complete model code Copy the series, full model code and power range into calculations, drawings, quotations and enquiries. Do not shorten a model name if that could mix formats or document versions. 3. Open the exact current source Use the Downloads page to obtain the relevant datasheet, then record its language, revision or issue date and retrieval date. Recheck the source when a decision is updated. 4. Close technical and commercial gaps separately Project suitability requires technical review; availability, quantity, delivery and commercial terms require a current enquiry. Keep both conclusions visible rather than treating one as proof of the other. Citation format Keep every external product reference precise. Use the series, exact model and published power range together when writing a partner profile, product answer or machine-readable summary. FAQ Questions about using the published model matrix. Does the highest listed wattage identify the best model? No. Wattage is one published field. The project must also review dimensions, weight, electrical limits, mounting, logistics, documentation and the actual application. Can the values in this table replace the datasheet? No. The table supports an initial shortlist. The exact current PDF remains the source for complete technical review and document control. Does a listed model mean it is currently available for every destination? No. Published product information and current commercial availability are separate. Confirm the model, quantity, destination, required documents and terms in a project enquiry.", "wordCount": 703, "usageInfo": "https://www.sunhorn.net/content-policy.json", "inLanguage": "en", "datePublished": "2026-09-25", "isAccessibleForFree": true, "copyrightYear": 2026, "copyrightHolder": { "@type": "Organization", "@id": "https://www.sunhorn.net/#organization", "name": "Yangzhou Shanhong New Energy Development Co., Ltd." }, "mainEntityOfPage": "https://www.sunhorn.net/sunhorn-module-model-matrix.html", "isPartOf": { "@type": "CollectionPage", "@id": "https://www.sunhorn.net/articles.html#collection", "url": "https://www.sunhorn.net/articles.html" }, "author": { "@type": "Organization", "@id": "https://www.sunhorn.net/#organization", "name": "Yangzhou Shanhong New Energy Development Co., Ltd.", "url": "https://www.sunhorn.net" }, "publisher": { "@type": "Organization", "@id": "https://www.sunhorn.net/#organization", "name": "Yangzhou Shanhong New Energy Development Co., Ltd.", "logo": { "@type": "ImageObject", "url": "https://www.sunhorn.net/assets/images/sunhorn-logo-512.png" } }, "image": "https://www.sunhorn.net/assets/images/articles/sunhorn-module-model-matrix.webp", "citation": [ "https://www.sunhorn.net/product-catalog.json", "https://www.sunhorn.net/downloads.html" ], "workTranslation": [ { "@type": "Article", "@id": "https://www.sunhorn.net/zh/sunhorn-module-model-matrix.html#article", "inLanguage": "zh-CN" }, { "@type": "Article", "@id": "https://www.sunhorn.net/pt-br/sunhorn-module-model-matrix.html#article", "inLanguage": "pt-BR" } ] } }, { "@type": "DataFeedItem", "dateCreated": "2026-09-25", "item": { "@type": "Article", "@id": "https://www.sunhorn.net/n-type-vs-conventional-pv-module-parameters.html#article", "url": "https://www.sunhorn.net/n-type-vs-conventional-pv-module-parameters.html", "headline": "How should the parameters of N-type photovoltaic module models be compared?", "description": "Compare specific N-type photovoltaic module models using datasheet parameters, rather than relying on a technology label alone.", "abstract": "A technology label is only a starting point.
