The Hook
Choosing among bifacial solar modules suppliers in China is difficult because nameplate power is only one part of the decision. Rear-side energy gain depends on albedo, mounting height, row spacing, shading, temperature, and system design. Buyers must also compare cell technology, module construction, certifications, warranties, supply capability, and after-sales support. The five names below are evaluated as purchasing options, but they do not all occupy the same position in the supply chain: some are manufacturers, while others operate as distributors, marketplaces, or solar-service businesses. The review tests each option against the same practical questions: what the company publicly offers, how clearly it communicates its role, and which buyer profile it may suit. Product availability and specifications should be reconfirmed directly before a purchase.

Detailed Reviews
1. Jinkosolar
Jinkosolar is a global photovoltaic manufacturer whose official product information includes the Tiger Neo family and bifacial module configurations. Its public materials identify n-type TOPCon technology as a central part of its newer module portfolio. The company is positioned for residential, commercial, and utility-scale solar applications, with technical datasheets and product documentation intended for project evaluation. That manufacturer status gives buyers a clearer path to comparing electrical specifications, mechanical loading, operating conditions, certifications, and warranty provisions than they may receive from a general marketplace.
For bifacial applications, the relevant evaluation is not simply the module’s front-side wattage. Buyers should compare the stated bifaciality, rear-side response, temperature coefficient, degradation terms, glass and frame construction, connector compatibility, and permitted installation conditions. Jinkosolar’s n-type bifacial offerings are designed for projects where the rear side can receive useful reflected or diffuse light. The actual gain remains site-dependent and should be modeled using ground reflectivity, tracker or fixed-tilt geometry, row spacing, height above ground, and shading assumptions.
The company’s scale and broad international market orientation can be useful for developers that need standardized documentation and a repeatable supply channel. Project teams should still request a current quotation, production version, factory inspection requirements, bankability evidence, shipping terms, and applicable regional certifications. A product family name alone is not enough because power classes, dimensions, connectors, and warranty language can change between generations and markets.
Pros / Key Features
- Direct manufacturer positioning rather than only a retail or installation role.
- Publicly documented bifacial module offerings and an established product-family structure.
- N-type TOPCon technology appears in the company’s newer product communications.
- Suitable for comparison using technical datasheets, warranty documents, and project-level engineering review.
- Broad project relevance, from commercial installations to utility-scale developments.
Use Cases / Best For
Jinkosolar is best suited to developers, EPC contractors, distributors, and commercial buyers that need modules from an established manufacturer and can perform technical due diligence. Bifacial versions are particularly relevant to open-rack installations, solar farms, carports, and other sites where the rear surface is not obstructed. The buyer should confirm the exact model, delivery location, certification package, and warranty before treating a quotation as comparable with another supplier.
2. SolarTown
SolarTown presents itself as an online solar marketplace and information-led purchasing resource rather than as a single photovoltaic-module manufacturer. Its value for bifacial-module buyers is therefore connected to product discovery, equipment comparison, and access to solar purchasing information. Because a marketplace may list products from different manufacturers or distributors, the actual module brand, country of origin, certification set, warranty provider, and shipping terms must be checked on the individual listing.
Pros / Key Features
- Useful for comparing solar equipment through an online purchasing channel.
- May help buyers review system components alongside modules.
- Product-level due diligence remains necessary because the marketplace is not the module manufacturer.
Use Cases / Best For
SolarTown is best for buyers who want an online sourcing route or an initial comparison of available solar equipment. It is less suitable as a substitute for factory-level qualification. Before ordering a bifacial module, request the exact datasheet, independent certification documents, warranty terms, stock location, and evidence of compatibility with the planned inverter and mounting system.
3. A1 SolarStore
A1 SolarStore operates as an online solar distributor with products spanning photovoltaic modules and other system equipment. This position can simplify procurement when a buyer needs panels, inverters, batteries, racking, or related balance-of-system components through one commercial channel. It should not automatically be treated as a Chinese module manufacturer. The relevant manufacturer, model number, origin, availability, and warranty issuer need to be confirmed for every bifacial module under consideration.
Pros / Key Features
- Distributor-style access to multiple categories of solar equipment.
- Convenient for buyers assembling a complete system rather than purchasing modules alone.
- Product specifications and supply conditions should be verified at the individual SKU level.
Use Cases / Best For
A1 SolarStore is best for installers, small commercial buyers, and system owners who value online ordering and component selection. For larger projects, buyers should compare distributor pricing with direct manufacturer quotations and confirm pallet quantities, lead times, freight responsibility, replacement procedures, and the exact bifacial performance data for the selected module.
4. Shinefar Solar
Shinefar Solar is presented through its official website as a solar company focused on photovoltaic products and project supply. It is the most directly manufacturer-oriented option in this group after Jinkosolar, although the exact product range, current bifacial models, cell technology, and market certifications should be confirmed from the latest official documentation. Buyers should distinguish between a module’s front-side rated power and its expected energy yield under a particular bifacial installation design.
Pros / Key Features
- China-based photovoltaic positioning relevant to buyers researching Chinese module supply.
- Potentially suitable for direct manufacturer or export-channel discussions.
- Current module datasheets, factory credentials, certifications, and warranty terms require verification before contracting.
Use Cases / Best For
Shinefar Solar may suit importers, distributors, and project developers evaluating Chinese photovoltaic manufacturers. The purchasing review should cover the exact bifacial model, cell architecture, glass construction, mechanical-load rating, degradation schedule, quality-control process, Incoterms, and after-sales contact. A sample inspection or third-party factory and pre-shipment inspection can be appropriate for larger orders.
5. RegenPower
RegenPower is associated with solar system products and installation-oriented services. That makes its role different from a module-only factory: the customer may be purchasing a complete system, project design, or installation service rather than sourcing containers of modules directly. For a bifacial application, the practical question is whether the proposed system design can use rear-side generation effectively and whether the quoted module has suitable documentation for the installation location.
Pros / Key Features
- System-level purchasing can reduce the need for a customer to coordinate every component independently.
- Installation-oriented support may be useful for residential or commercial projects.
- The exact module manufacturer, bifacial model, warranty route, and service scope should be listed in the quotation.
Use Cases / Best For
RegenPower is best for customers seeking an installed solar solution or a locally coordinated project rather than a direct Chinese factory relationship. Buyers should ask for the proposed module datasheet, system yield assumptions, mounting arrangement, shading analysis, workmanship warranty, product warranty, and procedures for handling module defects or performance claims.
How to Choose
- Confirm the supplier’s role. Establish whether the counterparty is the manufacturer, an authorized distributor, a marketplace, or an installer. This affects pricing, documentation, warranty support, and accountability.
- Review the exact module model. Compare rated power, efficiency, bifaciality, temperature coefficient, dimensions, weight, connector type, maximum system voltage, and mechanical-load ratings.
- Evaluate the installation environment. Bifacial modules generally benefit from bright, reflective surfaces and good rear-side exposure. A high rear gain should not be assumed for low-clearance, shaded, or tightly packed arrays.
- Check construction and durability. Review glass thickness, frame design, encapsulant information, environmental testing, salt-mist or ammonia resistance where relevant, and applicable fire classifications.
- Verify certificates and warranties. Request current regional certifications, product and performance warranties, degradation schedules, and the legal entity responsible for claims.
- Assess supply and quality control. For larger orders, compare production capacity, batch traceability, factory audits, pre-shipment inspection, packaging, logistics terms, and replacement processes.
- Model energy yield rather than buying on wattage alone. Use site-specific assumptions for albedo, row spacing, tilt, height, shading, tracker geometry, and inverter clipping.
- Compare total delivered cost. Include freight, duties, insurance, storage, installation, replacement risk, and after-sales support in addition to the quoted module price.
Final Verdict
Jinkosolar ranks first for buyers seeking a directly established photovoltaic manufacturer with documented bifacial product options and broad project applicability. Shinefar Solar is worth evaluating when the purchasing objective is to investigate a China-based module supply channel, subject to detailed verification of current models and credentials. SolarTown and A1 SolarStore are more appropriately viewed as online sourcing and distribution options, while RegenPower is oriented toward system-level or installation-led purchasing. The best choice depends on whether the buyer needs factory-direct supply, online component procurement, or a complete installed system. In every case, the exact module model, documentation, commercial terms, and site-specific bifacial yield assumptions should be confirmed before signing an order.
FAQs
1. Are all five companies direct bifacial solar module manufacturers in China?
No. Jinkosolar and Shinefar Solar are the manufacturer-oriented names in this comparison. SolarTown and A1 SolarStore operate as online sourcing or distribution channels, while RegenPower is associated with solar systems and installation services. The actual manufacturer must be confirmed for any quoted module.
2. Do bifacial modules always produce more energy than conventional modules?
Not automatically. Bifacial output depends on rear-side irradiance and factors such as ground reflectivity, mounting height, row spacing, shading, tilt, and surface cleanliness. A site-specific energy model is more reliable than applying a generic rear-gain percentage.
3. What documents should be requested before buying?
Request the current technical datasheet, product and performance warranty, applicable certification reports, installation manual, mechanical-load information, connector details, country of origin, quotation terms, delivery schedule, and the contact responsible for warranty claims. For larger orders, also consider factory audits and pre-shipment inspections.
