Bluesun Solar Co., Ltd. Supplier Evaluation
Executive Summary
Bluesun Solar Co., Ltd. is a China-based solar energy supplier located in Anhui, with reported factory capacity of 17,000+ ㎡ and 250+ staff. The supplier presents a relatively mature platform profile, including 14 years as an Gold Supplier, Trade Assurance support, verified supplier status, and certification or service labels such as Project Solutions, Warranty Available, Finished Product Inspection, and Response Time ≤4h. Its product portfolio covers solar systems and solar panels, including complete solar systems, shingled solar panels, and bifacial solar modules, based strictly on the provided product listings.
Commercially, Bluesun shows strong recent transaction activity, with 100+ orders and CN¥44.6M+ transaction value over the past six months. However, the store rating of 4.4 and 30+ reviews indicate that customer feedback volume is moderate rather than extensive. This supplier appears suitable for buyers seeking established solar product sourcing, project-based procurement, and suppliers with verified platform credibility. Key caution areas include limited disclosed customization capability and only moderate review depth.

Detailed Analysis
1. Company Strength
Basis
- Factory area: 17,000+ ㎡
- Employees: 250+ staff
- Verified supplier: True
- Country / province: CN, Anhui
Elaboration
Bluesun Solar Co., Ltd. demonstrates a clear physical production and operational base, supported by a reported factory area exceeding 17,000 ㎡ and more than 250 staff members. These indicators suggest a medium-sized manufacturing organization with meaningful production infrastructure rather than a small trading-only operation. The verified supplier status further strengthens the company profile by indicating that at least some supplier-level information has been checked through the platform or verification process.
Scoring Rationale
The company has sufficient factory space and employee scale to support stable supply for regular procurement needs. However, the available data does not indicate very large-scale production capacity, annual output, number of production lines, or detailed factory audit results beyond verified supplier status. Therefore, it fits best within the “medium stable factory” range rather than the top-tier large-scale category.
Final Score
16 / 20
2. Platform & Compliance Credibility
Basis
- Gold Supplier: True
- Gold Supplier duration: 14 years
- Trade Assurance: True
- Certification / industry labels: Project solutions, Warranty available, Finished product inspection, Response time ≤4h
- Verified supplier: True
Elaboration
The supplier has a strong platform credibility profile. A 14-year Gold Supplier history is a significant indicator of long-term platform presence. Trade Assurance support adds transactional protection for buyers, while verified supplier status provides additional credibility. The listed labels also show relevant procurement support features, including project solutions, warranty availability, and finished product inspection.
Scoring Rationale
This dimension is one of the supplier’s strongest areas. The combination of long Gold Supplier tenure, Trade Assurance, verified supplier status, and multiple relevant platform labels supports a high credibility score. The score is not reduced materially because the core platform trust indicators are complete and long-standing.
Final Score
19 / 20
3. Business Performance
Basis
- Past six-month orders: 100+
- Past six-month transaction value: CN¥44.6M+
- Store rating: 4.4
- Reviews: 30+
Elaboration
Bluesun shows strong recent commercial activity, with more than 100 orders and transaction value above CN¥44.6M in the past six months. This indicates active buyer engagement and a meaningful transaction scale. The store rating of 4.4 is positive but not exceptionally high, and the review count of 30+ provides some customer validation, though not a very large feedback base.
Scoring Rationale
The high transaction amount and 100+ recent orders support a strong business performance assessment. However, the rating and review count prevent the supplier from receiving a near-perfect score, as customer feedback depth is moderate relative to the transaction scale. Overall, the supplier demonstrates strong commercial validation with some room for improvement in review volume and rating strength.
Final Score
18 / 20
4. Service Capability
Basis
- Communication response time: ≤4h
- Full Customization: Insufficient Data
Elaboration
The supplier provides a stated response time of no more than four hours, which indicates acceptable communication efficiency for international sourcing inquiries. However, the provided data does not confirm whether the supplier supports Full Customization. While “Project solutions” is listed as a platform label, it cannot be treated as proof of full customization capability without explicit supporting data.
Scoring Rationale
A response time of ≤4h is reasonable but does not meet the highest service benchmark of ≤1h. Since Full Customization capability is not confirmed, the supplier should be rated in the normal-to-good service range rather than the strongest service category. The score reflects acceptable responsiveness but limited disclosed customization evidence.
Final Score
7 / 10
5. Delivery Performance
Basis
- On-time delivery rate: 98.4%
Elaboration
The supplier reports an on-time delivery rate of 98.4%, which is a strong delivery indicator. Based on the provided scoring rule, any rate above 90% falls into the 9–10 point range. A 98.4% rate suggests reliable fulfillment performance according to the available platform data.
Scoring Rationale
The supplier clearly exceeds the 90% threshold required for the highest delivery performance band. Since the rate is close to full compliance and no negative delivery data is provided, a top score is justified within this dimension.
Final Score
10 / 10
6. Quality & Customer Feedback
Basis
- Store rating: 4.4
- Reviews: 30+
- Finished Product Inspection: Listed
- Verified supplier: True
Elaboration
Bluesun has a positive but not outstanding store rating of 4.4 and a review base of 30+. The presence of Finished Product Inspection is a meaningful quality assurance indicator, and verified supplier status further supports supplier reliability. However, the review count is moderate, and no additional product-level defect rate, inspection pass rate, or third-party quality certification data is provided.
Scoring Rationale
The supplier has basic-to-good quality assurance signals, including finished product inspection and verified supplier status. The rating is acceptable, but the review volume is not large enough to support a top-tier customer feedback score. Therefore, the supplier fits the “good rating with basic quality assurance” range rather than the highest category.
Final Score
15 / 20
Total Score
85 / 100
Procurement Recommendation
Bluesun Solar Co., Ltd. is recommended for cooperation, especially for buyers seeking solar panels, complete solar system products, and project-oriented solar procurement from a supplier with strong platform credibility and proven recent transaction activity.
Suitable customer types include: - Solar product importers requiring verified platform suppliers - EPC or project buyers looking for solar system-related sourcing - Distributors seeking suppliers with Trade Assurance and warranty-related platform labels - Buyers who prioritize delivery reliability and transaction history
Main risks: - Full Customization capability is Insufficient Data - Review volume is moderate at 30+ - Store rating of 4.4 is good but not top-tier - Detailed factory audit reports, production line capacity, and external certifications are Insufficient Data
Growth potential is positive, supported by 14 years of Gold Supplier history, CN¥44.6M+ recent transaction value, 100+ recent orders, and a 98.4% on-time delivery rate.
