Detailed Analysis

1. Company Strength

Basis
- Factory area: 29,000+㎡
- Employees: 130+ staff
- Verified supplier: True
- Factory location: Zhejiang, China

Elaboration
The supplier has a clearly stated physical production base with a factory area above 29,000㎡ and over 130 employees. This indicates a meaningful manufacturing footprint rather than a very small trading setup. The verified supplier status adds credibility to the company profile, although no specific factory audit body, factory certification name, or production line capacity data is provided.

Scoring Rationale
The company demonstrates medium-to-strong manufacturing capability based on factory size and workforce. However, the available data does not include detailed production capacity, annual output, equipment lists, or named factory certifications, so it cannot be rated as a fully large-scale, highly transparent supply chain. The score reflects a stable mid-sized factory with credible basic production strength.

Final Score
16 / 20

2. Platform & Compliance Credibility

Basis
- Gold Supplier: True
- Gold Supplier duration: 22 years
- Trade Assurance: True
- Verification status: Verified supplier
- Certification/industry labels: Finished product inspection, Full customization, On-time delivery 91.1%, Response time ≤4h

Elaboration
The supplier has a long presence, with 22 years as a Gold Supplier. Trade Assurance support and verified supplier status strengthen platform credibility. The listed platform labels also cover inspection, customization, delivery, and response time. However, no independent compliance certifications such as ISO, CE, RoHS, or product-specific electrical certifications are provided in the dataset.

Scoring Rationale
The 22-year Gold Supplier history is a strong trust signal, and Trade Assurance improves transaction protection. The profile also includes several operational credibility labels. The only limitation is the absence of named third-party compliance or product certification data, so the score is high but not perfect.

Final Score
18 / 20

3. Business Performance

Basis
- Orders in past 6 months: 100+
- Transaction amount in past 6 months: CN¥4.3M+
- Store rating: 4.8
- Reviews: 50+

Elaboration
The supplier shows active recent trading performance, with more than 100 orders and over CN¥4.3M in transaction value during the past six months. A 4.8 rating is positive, and 50+ reviews provide some customer feedback base. These figures suggest the supplier has ongoing commercial traction on the platform.

Scoring Rationale
The order volume and transaction amount indicate stable commercial activity rather than limited or unproven sales. The rating is strong, but the review count is moderate rather than very large. Therefore, the supplier fits the upper range of stable mid-to-high business performance, but the available review volume does not justify a maximum score.

Final Score
17 / 20

4. Service Capability

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

Elaboration
The supplier provides a response time within 4 hours, which is acceptable for international B2B communication but does not meet the strongest benchmark of response within 1 hour. Full customization is listed, indicating the supplier may support customized requirements, although no details are provided on customization scope, engineering support, branding, packaging, or MOQ for customized orders.

Scoring Rationale
Service capability appears solid because the supplier responds within a reasonable timeframe and supports full customization. However, because the response time is not within 1 hour and customization details are limited, the score should remain in the normal-to-good range rather than the top tier.

Final Score
8 / 10

5. Delivery Performance

Basis
- On-time delivery rate: 91.1%

Elaboration
The reported on-time delivery rate is 91.1%, which exceeds the 90% threshold. This indicates generally reliable delivery execution based on the available platform data. No additional data is provided on average lead time, logistics methods, delay handling, or regional delivery performance.

Scoring Rationale
Based strictly on the scoring criteria, an on-time delivery rate above 90% qualifies for 9–10 points. Since the rate is only slightly above 90% and no broader delivery records are available, a strong but not maximum score is appropriate.

Final Score
9 / 10

6. Quality & Customer Feedback

Basis
- Store rating: 4.8
- Reviews: 50+
- Finished product inspection: Listed
- Verified supplier: True
- Factory Verification: Insufficient Data

Elaboration
The supplier has a positive 4.8 store rating and more than 50 reviews, indicating generally favorable customer feedback. Finished product inspection is listed, which supports basic quality control credibility. The supplier is also marked as verified, but the data does not explicitly confirm Factory Verification as a separate quality assurance label.

Scoring Rationale
The quality profile is favorable due to the high rating and finished product inspection label. However, the review count is not extensive, and the dataset does not provide detailed inspection procedures, defect rates, product certifications, warranty terms, or explicit Factory Verification information. Therefore, the supplier fits the “good quality foundation” range rather than the highest category.

Final Score
16 / 20

Total Score

84 / 100

Procurement Recommendation

Cooperation is recommended with standard procurement controls. Zhejiang TTN Electric Co., Ltd. is suitable for buyers seeking solar inverter suppliers with platform credibility, flexible low MOQ options, proven recent transaction activity, and acceptable delivery reliability. It may be especially suitable for small-to-medium importers, trial-order buyers, and procurement teams requiring Trade Assurance protection.

Key risks include insufficient data on product certifications, detailed factory audit records, production capacity, technical compliance, warranty terms, and explicit Factory Verification. Growth potential appears positive based on 22 years of Gold Supplier history, CN¥4.3M+ recent transaction value, 100+ recent orders, full customization capability, and a 91.1% on-time delivery rate. For larger or regulated purchases, buyers should request product certificates, factory audit documents, test reports, and sample validation before scaling orders.
