Sunroko Power Co., Limited Supplier Evaluation
Executive Summary
Sunroko Power Co., Limited is a China-based solar energy system supplier located in Anhui, with reported factory space of over 10,000㎡ and more than 100 staff. Its listed product portfolio focuses on hybrid solar energy systems, home storage energy systems, industrial all-in-one solar power solutions, and photovoltaic hybrid solar systems. The supplier shows a moderate-to-strong operational base, supported by verified supplier status, Gold Supplier membership for 2 years, Trade Assurance availability, and measurable business activity over the past six months.
Commercial performance appears stable, with 40+ orders and CN¥2.6M+ transaction value in the last six months. The store rating is high at 4.9, though the review count is limited at 9, which reduces the depth of customer feedback validation. Service responsiveness is strong, with response time reported as ≤1 hour, while customization capability is not clearly stated. Overall, this supplier is suitable for buyers seeking mid-scale solar system procurement with platform-backed transaction protection, but quality validation should be strengthened before large-volume purchasing.

Detailed Analysis
1. Company Strength
Basis
- Factory location: Anhui, China
- Factory area: 10,000+㎡
- Employees: 100+ staff
- Verified supplier: True
Elaboration
Sunroko Power Co., Limited demonstrates a meaningful physical operating base with more than 10,000㎡ of factory area and over 100 employees. This indicates the supplier has more than a basic workshop-level setup and is likely capable of handling structured production and order fulfillment for solar energy system products. The verified supplier status adds credibility to its company profile and supports the existence of a legitimate manufacturing or supply operation.
Scoring Rationale
The company does not appear to be a small or weak supplier based on the disclosed factory size and employee count. However, the available data does not indicate a very large-scale production base, advanced production capacity figures, annual output, or detailed factory audit results. Therefore, it is best positioned as a medium-sized stable supplier rather than a top-tier large-scale supply chain operator.
Final Score: 17 / 20
2. Platform & Compliance Credibility
Basis
- Gold Supplier: True
- Gold Supplier duration: 2 years
- Trade Assurance: True
- Certification / industry labels: “On-time delivery 88.0%”, “Response time ≤1h”
- Verified supplier: True
Elaboration
The supplier has several important platform credibility indicators, including Gold Supplier status, Trade Assurance support, and verified supplier status. These factors reduce basic transaction risk and provide buyers with some level of platform-backed protection. However, the Gold Supplier duration is relatively short at 2 years, and the provided certification or industry labels are operational indicators rather than formal product certifications or compliance certificates.
Scoring Rationale
Core platform credibility is present, especially through Gold Supplier status and Trade Assurance. The supplier also has verified supplier status, which strengthens trustworthiness. However, the limited Gold Supplier history and lack of disclosed product certifications, factory audit details, or compliance documents prevent it from reaching the highest credibility tier.
Final Score: 16 / 20
3. Business Performance
Basis
- Orders in past 6 months: 40+
- Transaction value in past 6 months: CN¥2.6M+
- Store rating: 4.9
- Reviews: 9
Elaboration
The supplier has recorded measurable business activity, with more than 40 orders and transaction value above CN¥2.6M in the last six months. This suggests the supplier is commercially active and has completed a meaningful level of platform transactions. The 4.9 store rating is positive, but the review count of 9 is relatively low, which limits the reliability of the rating as a broad customer satisfaction indicator.
Scoring Rationale
The transaction value is reasonably strong and the number of recent orders indicates active market demand. However, the relatively small review base means customer feedback is not yet deep enough to fully validate long-term consistency. The supplier therefore fits the stable medium-scale transaction category rather than the high-volume, highly validated category.
Final Score: 16 / 20
4. Service Capability
Basis
- Response time: ≤1 hour
- Full Customization: Insufficient Data
Elaboration
The supplier’s response time of ≤1 hour is a strong service indicator and suggests efficient communication during inquiry and negotiation stages. Fast response is particularly valuable for technical products such as solar energy systems, where quotation clarification, configuration discussion, and after-sales coordination may require frequent communication. However, there is no provided data confirming Full Customization capability.
Scoring Rationale
The response speed meets the highest service-response benchmark. Nevertheless, because strong customization capability is not confirmed, the supplier cannot be rated at the top level for service capability. The score reflects excellent communication responsiveness but incomplete evidence on customization depth.
Final Score: 8 / 10
5. Delivery Performance
Basis
- On-time delivery rate: 88.0%
Elaboration
An 88.0% on-time delivery rate indicates generally stable delivery performance, though not yet at a highly reliable level. For solar system procurement, delivery reliability is important because components or complete systems are often tied to installation schedules and project timelines. An 88% rate suggests the supplier can fulfill most orders on time, but buyers should still confirm lead times and shipment schedules before placing larger or time-sensitive orders.
Scoring Rationale
According to the scoring standard, an on-time delivery rate between 80% and 89% falls into the 7–8 point range. Since 88.0% is near the upper end of that band, the supplier receives the higher score within this range.
Final Score: 8 / 10
6. Quality & Customer Feedback
Basis
- Store rating: 4.9
- Reviews: 9
- Verified supplier: True
- Finished Product Inspection: Insufficient Data
- Factory Verification: Supplier marked as verified
Elaboration
The supplier has a high store rating of 4.9, which is a positive signal regarding buyer satisfaction. However, the review count is only 9, making the feedback sample relatively limited. Verified supplier status provides some quality-related confidence at the company level, but there is no disclosed Finished Product Inspection data or detailed quality inspection system information.
Scoring Rationale
The high rating supports a favorable quality perception, but the limited number of reviews weakens the statistical reliability of customer feedback. In addition, the absence of explicit Finished Product Inspection information prevents a stronger quality assurance score. The supplier shows good basic quality indicators, but the evidence is not comprehensive enough for a top-tier rating.
Final Score: 15 / 20
Total Score
80 / 100
Procurement Recommendation
Sunroko Power Co., Limited is recommended for cautious cooperation, especially for buyers seeking solar energy systems, home energy storage solutions, and photovoltaic hybrid system products through a platform-supported supplier with Trade Assurance. It is most suitable for small to medium-sized procurement projects, pilot orders, distributor testing, or buyers who require responsive communication and moderate transaction credibility.
Main risks include limited review volume, only 2 years of Gold Supplier history, no provided Finished Product Inspection data, and insufficient evidence of Full Customization capability. Its growth potential is positive due to its verified supplier status, 10,000+㎡ factory scale, 100+ staff base, fast response time, and CN¥2.6M+ recent transaction value. For larger-volume procurement, buyers should request inspection reports, production capacity details, product certifications, and sample validation before scaling orders.
