Guangdong Sunray Power Co., Ltd. Supplier Evaluation

Executive Summary

Guangdong Sunray Power Co., Ltd. is a China-based supplier located in Guangdong, with a reported factory area of 24,000+ m² and 720+ staff. Based on the provided data, the company demonstrates strong production capacity for hybrid solar inverter products, including 4KW and 5KW models under the Sumry/SUMRY product lines. The supplier has verified supplier status, Gold Supplier membership for 2 years, Trade Assurance support, and platform tags including Finished Product Inspection, Full Customization, ODM service availability, and warranty availability. Its recent commercial performance is solid, with 70+ orders and CN¥3.2M+ transaction value over the past six months, supported by a 4.9 store rating, though the review volume is limited at 10+. The supplier appears suitable for buyers seeking mid-to-large-scale sourcing of hybrid solar inverter products, especially customers requiring customization or ODM support. Key risks relate mainly to the relatively short Gold Supplier history and limited review base.

Detailed Analysis

1. Company Strength

Basis
- Factory area: 24,000+ m²
- Staff count: 720+ staff
- Verified supplier: True
- Factory location: Guangdong, China

Elaboration
The supplier shows a substantial physical and workforce scale. A 24,000+ m² factory and 720+ staff indicate a sizable manufacturing operation rather than a small trading setup. The verified supplier status further strengthens confidence that the company has passed a platform-level supplier verification process.

Scoring Rationale
The company fits the profile of a large-scale and relatively stable supply chain participant. The combination of factory size, employee count, and verified supplier status supports a high score. However, the provided data does not include more detailed factory audit reports, production line numbers, annual capacity, or specific factory certification names, so a perfect score is not assigned.

Final Score
19 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 2 years
- Trade Assurance: True
- Verified supplier: True
- Certification/industry tags: Warranty available, Finished product inspection, Full customization, ODM service available

Elaboration
The supplier has several important platform credibility indicators, including Gold Supplier status, Trade Assurance support, and verified supplier status. The presence of inspection, warranty, customization, and ODM-related tags provides additional platform-level credibility for procurement evaluation.

Scoring Rationale
The supplier has the core compliance and platform trust elements expected from a credible supplier. However, the Gold Supplier history is only 2 years, which is relatively short compared with long-established platform suppliers. Certification information is also presented as platform/industry tags rather than detailed third-party certificates, so the credibility level is strong but not at the highest tier.

Final Score
16 / 20

3. Business Performance

Basis
- Orders in past 6 months: 70+
- Transaction value in past 6 months: CN¥3.2M+
- Store rating: 4.9
- Reviews: 10+

Elaboration
The supplier has demonstrated recent transaction activity, with more than 70 orders and over CN¥3.2M in transaction value during the past six months. The 4.9 store rating is strong and indicates positive buyer satisfaction based on available feedback. However, the review count of 10+ is relatively limited compared with the order volume.

Scoring Rationale
The business performance is above average, supported by meaningful transaction value and a high rating. The supplier appears commercially active and has proven recent sales traction. The score is moderated because the review base remains small, which limits the depth of customer feedback validation.

Final Score
17 / 20

4. Service Capability

Basis
- Response time: ≤4h
- Full customization: Listed as available
- ODM service: Listed as available

Elaboration
The supplier responds within four hours, which indicates acceptable communication efficiency for international procurement. The availability of Full Customization and ODM service suggests the supplier can support buyers with non-standard product requirements or customized inverter specifications, based on the platform tags provided.

Scoring Rationale
The service capability is solid because the supplier supports customization and ODM services. However, the response time is not within the ≤1 hour threshold required for the highest service score. Therefore, the supplier is best classified as having normal-to-good service capability rather than exceptional responsiveness.

Final Score
8 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 96.7%

Elaboration
The supplier’s reported on-time delivery rate is 96.7%, which is above the 90% benchmark for strong delivery performance. This suggests that the supplier has a reliable recent record of fulfilling orders within agreed delivery timelines.

Scoring Rationale
A 96.7% on-time delivery rate meets the highest scoring range for delivery performance. Based strictly on the provided data, delivery reliability is one of the supplier’s strongest measurable advantages.

Final Score
10 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 4.9
- Reviews: 10+
- Finished Product Inspection: Listed as available
- Verified supplier: True

Elaboration
The supplier has a strong store rating of 4.9, supported by at least 10 reviews. Finished Product Inspection is listed, which indicates a quality control mechanism at the finished goods stage. Verified supplier status also adds a level of quality-related credibility, although detailed inspection reports or quality certifications are not provided.

Scoring Rationale
The supplier shows good quality signals through its high rating, finished product inspection tag, and verified supplier status. The main limitation is the relatively small number of reviews, which means customer feedback depth is not yet extensive. No specific product quality certificates or detailed defect-rate data were provided, so the score remains in the strong but not top-tier range.

Final Score
16 / 20

Total Score

86 / 100

Procurement Recommendation

Cooperation is recommended, especially for buyers sourcing hybrid solar inverters who require a supplier with sizable production capacity, Trade Assurance support, customization capability, ODM service availability, and strong recent delivery performance.

The supplier is most suitable for mid-sized to larger buyers seeking stable production capacity and platform-backed transaction protection. Key risks include the relatively short 2-year Gold Supplier history, limited review volume of 10+, and insufficient data on detailed third-party factory certifications or product-specific certifications. Growth potential appears positive based on factory scale, 70+ recent orders, CN¥3.2M+ six-month transaction value, 4.9 rating, and 96.7% on-time delivery rate.
