AI-Powered supplier vetting

SummaryNINGBO RENPOWER NEW MATERIALS TECHNOLOGY CO., LTD. is a China-based limited company in Zhejiang that identifies as both a trading company and manufacturer/factory. It produces photovoltaic and portable solar products, including PV modules, solar cells, flexible and folding panels, solar blankets, and power stations. The supplier reports BSCI, ISO 9001, and ISO 14001 certifications, 10 production lines, 11–20 years of R&D engineer experience, and 6–10 quality-control staff. It has exported since 2010 and reports broad coverage across major global regions, with exports representing 90% of total sales. The available information supports production, export, product-development, and customization capabilities, but does not provide sufficient evidence to assess financial credibility, detailed after-sales performance, or independently verified customer cases.

Supplier typeThe supplier is explicitly identified as both a trading company and manufacturer/factory, with its business focused on producing PV modules, solar cells, solar blankets, flexible and folding panels, and portable power products. Its legal form is a limited company located in Ningbo, Zhejiang, China.

CertificationsThe supplier reports holding BSCI, ISO 9001, and ISO 14001 certifications. These stated certifications indicate coverage of social compliance, quality management, and environmental management, although the provided information does not include certificate numbers, validity dates, or issuing bodies.

After-Sales capabilityThe company describes itself as integrating installation and after-sales service and states that it provides technical support to customers. However, no details are provided on service locations, response times, warranty terms, or after-sales staffing, so the depth of this capability cannot be fully verified.

R&D capabilityThe supplier presents itself as a high-tech enterprise with R&D operations, reports 11–20 years of R&D engineer experience, and states that it launches new products and applies new technologies. Its product range includes multiple specialized solar formats, supporting an innovation capability assessment, although no patents or independently verified R&D achievements are provided.

Production capacityThe supplier explicitly describes manufacturing operations and reports 10 production lines, 6–10 quality-control staff, advanced facilities, product testing methods, and a strict quality-control system. These details provide direct evidence of established production capability for photovoltaic and portable solar products.

Customization capabilityThe supplier explicitly welcomes OEM cooperation and states that it can provide customized solutions. This supports customization capability, although the slices do not specify minimum order quantities, engineering procedures, tooling support, or examples of completed customized products.

Product Q&A

Q:Do these panels have brackets attached to the roof?

The component itself is equipped with a junction box connector output voltage. If you need to access the off-grid system, you need to purchase additional appropriate wiring.

Q:Can this solar panel accommodate 12V/24V/36V/48V batteries?

It can be used, but must be connected to a controller. When selecting the controller, it is necessary to adapt the maximum component input power that the controller can access (not exceeding).

Q:How many kilowatt hours can this solar panel produce in a day?

In the case of STC, the power generation is the product of standard power and time (W*H).

Q:What is the difference between high power modules and low power modules?

The biggest difference is that the efficiency of the cells used is not the same, which will result in different power generation efficiency of the PV modules. At the same time, due to the different efficiency of the cells used, their open voltage will not be the same. In addition, at the installation end, the high power module needs less quantity to meet the customer's demand compared to the low power module, which is also convenient for the wiring and installation at the installation end.
