Solar procurement becomes difficult when modules, inverters, structures, storage, controls and grid interfaces are discussed as separate products. A component can look competitive at the booth yet fit poorly with the voltage design, climate, operating strategy or delivery plan of the actual plant. SNEC PV 2027 is most useful when every candidate receives the same project case and answers for a clearly defined package.
SNEC PV+ runs from 2–4 June 2027 at National Exhibition and Convention Center (Shanghai). Its official scope covers PV manufacturing equipment and materials, cells and modules, projects and systems, energy storage and mobile energy. Buyers can use that breadth in several ways.
| Buyer mission | Starting evidence | Useful result from the show |
|---|---|---|
| Build a utility-scale solar plant | Site, grid, yield, design-load and delivery assumptions | Package shortlists with compatible technical boundaries |
| Develop a commercial or industrial system | Load profile, roof or ground conditions, tariff and operating limits | A workable generation, self-use and control concept |
| Add storage to a solar project | Dispatch duty, power, duration, cycling and grid or load objective | A defined storage-system boundary and degradation plan |
| Replace or expand installed equipment | Existing model, architecture, faults, spares and interface data | A compatible transition route with downtime and warranty effects visible |
The show visit should answer one primary project question. A utility-scale developer comparing module and inverter packages needs different evidence from a factory owner studying peak management, or an asset owner replacing equipment in an operating plant.
Issue one project case before the show
Prepare a concise project pack covering location, site layout, weather basis, temperature range, altitude where relevant, wind and snow design inputs, corrosion or soiling environment, DC capacity, target AC capacity, grid connection point, voltage architecture, mounting type, cable distances, construction schedule, logistics constraints and service expectations. Add the destination rules, grid requirements and owner specifications already identified by the project team.
For energy modelling, state the weather dataset, loss assumptions, availability basis, clipping approach, degradation assumptions and any required scenarios. For commercial and industrial projects, include the load profile, operating hours, backup or resilience objective, export limits and expected control priorities. Storage cases should define power, duration, usable-energy basis, cycling profile, depth of discharge, state-of-charge limits, ambient conditions, dispatch logic and the period over which capacity must be maintained.
Mark each input as confirmed, provisional or to be studied. This allows suppliers to identify the assumptions behind their proposal without silently filling gaps in different ways. If several project sizes are under review, keep them as named scenarios rather than mixing their figures in one request.
The meeting request can then list the decisions expected from each package: proposed model and configuration, design limits, interfaces, project-specific evidence, production source, delivery capability, exclusions and next verification step.
Compare each package on the same basis
For modules, record the exact model, cell and module construction, dimensions and weight, electrical ratings and tolerance, temperature behaviour, mechanical-load basis, environmental evidence, degradation assumptions and warranty entity. Ask how the bill of materials is controlled, which changes require notification, how serial numbers link to production and test data, and whether the offered production site and configuration match the documents supplied.
Bifacial, high-power or other design claims should be connected to the project layout and modelling assumptions. A higher nameplate rating may alter string design, handling, structure loading, row geometry or replacement strategy. Compare energy implications through the same project model rather than treating one catalogue figure as the project outcome.
For inverters, start with the proposed array and grid architecture. Review DC voltage and current limits, MPPT arrangement, DC/AC ratio assumptions, efficiency basis, overload behaviour, environmental rating, cooling, protection, grid functions, communications, plant-control interface, fault records, remote diagnostics, firmware management, local service and spare strategy. Identify which functions depend on optional hardware, software licences or later configuration.
Storage proposals need a precise boundary. Distinguish cells, modules, racks, battery-management system, thermal management, fire detection or suppression, containers, power-conversion system, transformer, energy-management system and site integration. Compare rated and usable energy, charge and discharge power, auxiliary consumption, operating limits, efficiency basis, cycling and calendar degradation, availability assumptions, augmentation strategy and capacity test method under the same dispatch case.
Structures and balance-of-system packages also affect plant performance. For fixed or tracking structures, review design loads, materials and coatings, foundations or roof interfaces, tolerances, fasteners, movement range, controls, installation method and maintenance. Cables, connectors, combiner equipment, transformers, switchgear, meters and communications should be tied to current, voltage, environmental, loss, protection and interface requirements.
Make system interfaces visible
Draw a responsibility map from module strings to the grid or facility connection point. Name the owner for array design, inverter and storage sizing, structure inputs, electrical protection, transformer and switchgear coordination, plant controller, SCADA or energy-management integration, communications protocol, cybersecurity requirements set by the owner, energy modelling, commissioning and performance testing.
For a solar-plus-storage system, confirm how the PV controller, inverter, power-conversion system, battery-management system and site or grid controller exchange commands and limits. Record who supplies each interface document, performs integration tests, manages software versions and leads fault investigation. A technically compatible list of components still needs one party to coordinate the complete operating sequence.
Request package drawings, datasheets, interface lists, certificates or test reports relevant to the offered model and destination, preliminary layouts, utility needs, monitoring architecture, commissioning outline and proposed acceptance tests. Certificates and reports should be matched to the exact product, configuration, manufacturing source and validity conditions rather than collected as a general supplier folder.
Reference projects are most useful when climate, voltage architecture, plant size, grid duty and product generation resemble the proposed case. Note meaningful differences and ask what additional evidence covers them. Site access and operating data require the owner’s permission, so confirm availability before building a travel plan around a reference visit.
Use supplier visits to test production and support
A factory visit becomes valuable when the shortlist depends on bill-of-material control, configuration, production capacity, testing, traceability or service preparation. Confirm that the proposed product family is made or assembled at the address and identify the contracting and warranty entities before the visit.
For modules, follow material receiving, storage, production stages, in-process checks, electrical and visual testing, serial-number traceability, final release and packing for the relevant product family. For inverters, storage systems, controls or power-conversion equipment, review configuration release, critical bought-out parts, assembly, software loading, calibration, functional and safety tests, factory acceptance, nonconforming control, preservation and packing.
Service capability needs evidence beyond a contact name. Review commissioning resources, training, diagnostic access, response and escalation route, local or regional spare coverage, repair or replacement process, firmware and configuration support, warranty claim handling and arrangements when several package suppliers are involved.
If equipment will ship in several lots, connect serial-number or configuration records to inspection, packing lists and delivery sequence. Record storage requirements at site, preservation periods, lifting or handling constraints and the checks needed before installation.
Compare delivery, acceptance and commercial scope
Ask candidates to quote against the same project case and separate base equipment, required options, software, communications, auxiliaries, recommended spares, testing, packing, freight assumptions, supervision, commissioning, training and service. Record production location, lead-time basis, delivery milestones, documents due at each stage, excluded work, payment triggers, warranty start and the commercial treatment of design changes.
Define acceptance by package and by system. Package checks may include document review, model and configuration verification, factory tests, inspection, traceability and packing. Site acceptance may depend on installation, communications, commissioning, stable operation, capacity or power tests, control functions and agreed performance conditions. The project team should state who approves each stage and how unresolved items affect shipment, handover or payment.
The final matrix should connect every project requirement to the offered product, design assumption, supporting evidence, production site, interface owner, open technical question, acceptance step, quoted scope and next decision. SNEC then becomes the start of a controlled project evaluation rather than a comparison of isolated efficiency, power or price claims.
