Guangdong Sunray Power Co., Ltd. Supplier Evaluation

Executive Summary

Guangdong Sunray Power Co., Ltd. is a China-based supplier located in Guangdong, with reported facilities of over 24,000㎡ and more than 720 staff. Based on the supplied data, the company appears to have a relatively strong production foundation for hybrid solar inverters, off-grid inverters, PV solar products, and residential solar-related products. Its profile shows Gold Supplier status for 2 years, Trade Assurance support, verified supplier status, and a 91.7% on-time delivery rate. Business activity is moderate, with over 20 orders and CN¥676.1K+ transaction value in the past six months. However, the review base is very limited, with only 2 reviews despite a 5.0 store rating. Service capability is acceptable based on response time within 3 hours, but Full Customization capability is not provided. Overall, this supplier is suitable for buyers seeking a mid-to-large manufacturing supplier with basic platform credibility, moderate transaction validation, and acceptable delivery performance, while requiring further quality and customization verification before large-scale procurement.

Detailed Analysis

1. Company Strength

Basis
- Factory area: 24,000+㎡
- Employees: 720+ staff
- Verified supplier: True
- Location: Guangdong, China

Elaboration
The supplier shows a sizable physical and staffing base. A factory area above 24,000㎡ and more than 720 employees indicate a relatively mature manufacturing organization rather than a small trading operation. The verified supplier status also provides basic support for the credibility of the company profile.

Scoring Rationale
The scale of both factory area and workforce supports a strong company-strength score. The data suggests meaningful production capacity and organizational depth. However, no additional factory audit details, production line count, annual capacity, or specific factory certification information is provided, so the score should not reach the absolute maximum.

Final Score
19 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier tenure: 2 years
- Trade Assurance: True
- Verified supplier: True
- Certification/industry labels: “Response time ≤3h”, “On-time delivery 91.7%”

Elaboration
The supplier has several core platform credibility indicators, including Gold Supplier status, Trade Assurance, and verified supplier status. These elements provide a basic level of transaction protection and platform-backed credibility. The supplier also displays operational labels related to response time and delivery performance.

Scoring Rationale
The supplier has the key credibility components required for platform-based sourcing. However, the Gold Supplier history is only 2 years, which limits long-term platform trust compared with suppliers that have maintained verified status for a longer period. Certification label information is also limited and does not include broader product or management certifications.

Final Score
16 / 20

3. Business Performance

Basis
- Past 6-month orders: 20+
- Past 6-month transaction value: CN¥676.1K+
- Store rating: 5.0
- Reviews: 2

Elaboration
The supplier has demonstrated measurable commercial activity in the past six months. More than 20 orders and CN¥676.1K+ in transaction value indicate that buyers have placed orders through the platform. The 5.0 store rating is positive, but the review count is very low.

Scoring Rationale
The transaction value and order count show moderate business validation, but the limited number of reviews weakens the reliability of the rating. A 5.0 score based on only 2 reviews is not enough to prove broad customer satisfaction. Therefore, the supplier fits a stable mid-level business performance profile rather than a highly proven high-volume supplier.

Final Score
15 / 20

4. Service Capability

Basis
- Communication response time: ≤3h
- Full Customization capability: Insufficient Data

Elaboration
The supplier’s response time of within 3 hours suggests acceptable communication efficiency. This is suitable for standard sourcing communication and initial quotation handling. However, the provided data does not confirm whether the supplier supports Full Customization.

Scoring Rationale
The response speed is reasonable but does not meet the strongest benchmark of response within 1 hour. Since customization capability is not provided, the service score must be limited. The supplier can be considered responsive enough for normal procurement communication, but its ability to handle custom product development or OEM/ODM requirements remains unverified.

Final Score
6 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 91.7%

Elaboration
The supplier’s reported on-time delivery rate exceeds 90%, which is a positive logistics and fulfillment indicator. This suggests that the supplier has been able to meet delivery commitments at a relatively strong level based on available platform data.

Scoring Rationale
According to the scoring standard, an on-time delivery rate above 90% falls into the 9–10 point range. Since the reported rate is 91.7%, the supplier qualifies for a strong delivery score. However, it is close to the lower end of the 90%+ range, so a score of 9 is more appropriate than 10.

Final Score
9 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 5.0
- Reviews: 2
- Verified supplier: True
- Finished Product Inspection: Insufficient Data
- Factory Verification: Supplier verification provided as True

Elaboration
The supplier has a perfect store rating, but the rating is based on only 2 reviews. This creates a limited customer feedback base and reduces confidence in the consistency of buyer satisfaction. Verified supplier status provides some credibility, but no Finished Product Inspection information is provided.

Scoring Rationale
The 5.0 rating is favorable, and verified supplier status supports basic quality credibility. However, the very small number of reviews prevents a strong conclusion about long-term quality consistency. The absence of Finished Product Inspection data also limits the assessment of quality-control transparency. The supplier therefore fits the lower end of the “good rating with basic quality support” range.

Final Score
14 / 20

Total Score

79 / 100

Procurement Recommendation

Cooperation is conditionally recommended. Guangdong Sunray Power Co., Ltd. appears suitable for buyers seeking hybrid solar inverter and residential solar-related products from a supplier with solid factory scale, verified platform status, Trade Assurance support, and acceptable delivery performance. It is more appropriate for small-to-medium trial orders or controlled batch procurement before larger commitments.

Main risks include the short 2-year Gold Supplier history, very limited review count, lack of provided Full Customization data, and insufficient information on Finished Product Inspection. Growth potential is supported by the supplier’s manufacturing scale, 720+ staff, 24,000+㎡ facility, and existing transaction activity, but buyers should request additional quality-control documents, inspection procedures, customization capabilities, and sample validation before placing high-volume orders.
