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+㎡ and 720+ staff. Based on the provided data, the company appears to have a relatively strong production foundation and is marked as a verified supplier. Its listed products are lithium battery and home energy system battery products, with MOQs ranging from 50 to 100 sets, indicating suitability for buyers with batch procurement needs rather than very small trial orders.

On -related indicators, the supplier has 3 years as a Gold Supplier, supports Trade Assurance, and lists tags including warranty availability, finished product inspection, response time within 5 hours, and 80.0% on-time delivery. Commercial performance shows 30+ orders and CN¥1.7M+ transaction value over the past six months, but customer feedback is limited, with a 3.5 store rating and only 2 reviews. Overall, this supplier may be suitable for buyers prioritizing production capacity and platform-backed transactions, while requiring additional quality validation before large-scale procurement.

Detailed Analysis

1. Company Strength

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

Elaboration:
The supplier demonstrates a relatively substantial manufacturing base, supported by a large reported factory area and a sizeable workforce. A 24,000+㎡ facility and 720+ staff indicate that the company is not a small workshop-style supplier, but rather has the organizational scale to support structured production and recurring order fulfillment. The verified supplier status further strengthens the credibility of its basic company profile.

Scoring Rationale:
The company’s physical scale and employee count place it closer to a large-scale production supplier. The presence of verified supplier status supports its operational credibility. However, the provided data does not include detailed factory audit reports, production line capacity, annual output, or specific factory certifications, so the score should not reach the maximum range.

Final Score: 18 / 20

2. Platform & Compliance Credibility

Basis:
- Gold Supplier: True
- Gold Supplier duration: 3 years
- Trade Assurance: True
- Certification / industry tags: Warranty available, Finished product inspection, Response time ≤5h, On-time delivery 80.0%

Elaboration:
The supplier has several important platform credibility signals, including Gold Supplier status and Trade Assurance support. These features reduce transaction risk compared with suppliers lacking platform-backed mechanisms. The 3-year Gold Supplier history provides a moderate credibility record, although it is not long enough to be considered a long-established platform presence.

Scoring Rationale:
The supplier has core platform protections in place, especially Gold Supplier status and Trade Assurance. The available tags also indicate some operational and quality-related transparency. However, the Gold Supplier duration is only 3 years, and the data does not provide a full set of third-party certifications, audited factory reports, or detailed compliance documentation. Therefore, the supplier fits the “core certifications present but not fully mature” range.

Final Score: 16 / 20

3. Business Performance

Basis:
- Orders in past 6 months: 30+
- Transaction value in past 6 months: CN¥1.7M+
- Store rating: 3.5
- Number of reviews: 2

Elaboration:
The supplier has visible transaction activity, with more than 30 orders and over CN¥1.7M in transaction value during the past six months. This indicates that the supplier has recent commercial traction and is not inactive on the platform. However, the customer feedback base is very limited, with only 2 reviews, and the store rating of 3.5 is moderate rather than strong.

Scoring Rationale:
The order count and transaction value suggest a certain level of business validation, but the low review count limits confidence in repeat customer satisfaction. The 3.5 rating also prevents the supplier from being assessed as high-performing from a buyer feedback perspective. As a result, the supplier should be considered commercially active but not strongly validated by customer feedback.

Final Score: 13 / 20

4. Service Capability

Basis:
- Communication response time: ≤5h
- Full Customization: Insufficient Data

Elaboration:
The supplier’s listed response time of within 5 hours indicates acceptable communication responsiveness for standard B2B procurement. This is useful for quotation requests, order discussion, and basic after-sales coordination. However, the data does not confirm whether the supplier supports Full Customization, OEM, ODM, private labeling, engineering modification, or other customization services.

Scoring Rationale:
A response time of ≤5h is reasonable but does not meet the highest service benchmark of ≤1h. Since Full Customization capability is not provided, the supplier cannot be scored as having strong customization support. The service profile is therefore assessed as basic to moderate rather than advanced.

Final Score: 6 / 10

5. Delivery Performance

Basis:
- On-time delivery rate: 80.0%

Elaboration:
The supplier’s on-time delivery rate is exactly 80.0%, which indicates that most orders are shipped on time, but there is still a meaningful delivery risk. For buyers with strict project timelines or downstream installation schedules, this level of delivery performance should be monitored carefully.

Scoring Rationale:
According to the scoring standard, an on-time delivery rate between 80% and 89% corresponds to 7–8 points. Since the supplier is at the lower boundary of this band, a conservative score is appropriate.

Final Score: 7 / 10

6. Quality & Customer Feedback

Basis:
- Store rating: 3.5
- Number of reviews: 2
- Finished product inspection: Listed
- Verified supplier: True
- Factory Verification: Supplier marked as verified; detailed factory verification report is Insufficient Data

Elaboration:
The supplier provides some quality assurance signals, including a finished product inspection tag and verified supplier status. These factors are positive because they suggest at least basic inspection and platform-level verification. However, the customer feedback base is weak, with only 2 reviews, and the store rating of 3.5 does not indicate strong customer satisfaction.

Scoring Rationale:
The supplier has basic quality control indicators, but the limited number of reviews significantly reduces confidence in actual buyer experience. The absence of detailed inspection standards, defect rates, product certifications, or a full factory verification report also prevents a higher score. The supplier therefore falls into a moderate-to-limited quality validation range.

Final Score: 12 / 20

Total Score

72 / 100

Procurement Recommendation

Cooperation can be considered with controlled risk management. Guangdong Sunray Power Co., Ltd. is suitable for buyers seeking lithium battery or home energy system battery suppliers with sizable production capacity, platform transaction protection, and moderate recent sales activity. It may be appropriate for batch procurement, sample-based supplier qualification, or buyers who can conduct their own technical and quality verification.

Key risks include limited customer feedback, a moderate 3.5 store rating, only 2 reviews, an 80.0% on-time delivery rate, and insufficient data on Full Customization, detailed factory audit results, and product-level certifications. Before placing large orders, buyers should request product specifications, test reports, warranty terms, inspection standards, sample validation, and delivery commitments. The supplier shows growth potential due to its scale, transaction volume, and platform credibility, but should be managed through staged procurement and strict quality checks.
