AI-Powered supplier vetting

SummaryThe supplier operates in solar, battery, power electronics, energy storage, and related electrical and automotive equipment businesses. It reports substantial solar and lithium-battery production infrastructure, including eight automated production lines, nearly 500 MW of annual solar module capacity, and annual lithium-battery throughput of 920,000 kWh. Customization is available across several models, and the supplier provides OEM services for well-known brands, but it does not provide 3D software design or ODM services and reported no new products in the past year. Quality resources include four inspection staff, but no quality-control testing equipment, and finished products are checked by packing staff. Service procedures exist, although records are incomplete or unavailable. Overseas service coverage is limited, with no overseas offices, agents, showrooms, or reported overseas-service countries.

Supplier typeThe supplier is a manufacturer and seller covering solar PV modules, lithium batteries, energy storage, power electronics, transformers, and related electrical equipment. Its described factory infrastructure and production activities support classification as a manufacturing supplier rather than a purely trading or service company.

R&D capabilityInnovation infrastructure appears limited: the supplier has one R&D engineer, no available R&D audit documentation, no SDK, no ODM service, no ERP/OA/CRM/SAP integration, and reported no new products in the past year. These are explicit limitations in documented R&D output and digital development support.

Production capacityThe supplier reports eight fully automated solar production lines, nearly 500 MW of annual solar-module capacity, and annual lithium-battery throughput of 920,000 kWh. However, quality testing equipment is reported as zero and finished products are checked by packing staff, so production scale is supported while production-quality control remains a concern.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and also provides OEM services for well-known brands. It does not provide 3D software design or ODM services, so customization is available but does not include every design-development model.

Product Q&A

Q:What is a Grid Connected Rooftop Solar PV System?

On grid connected rooftop or small solar photovoltaic (SPV) system, the DC power generated from solar panel is converted to AC power using power conditioning unit/Inverter and is fed to the grid. Operating modes of grid connected rooftop solar PV system can be explained.

Q:What types of roofs are suitable for Rooftop solar (RTS) system?

Rooftop solar PV systems can be installed on any type of roof having sufficient load bearing capacity.

Q:Will I get same annual energy from the RTS for all 25 years?

No. On exposure to sunlight and outside environment, the solar module lose their generation capacity and this is called degradation.

Q:What is the warranty period for the system?

The system comes with a 5-year warranty coverage.

Q:Is OEM customization available?

Yes, OEM service is available with options for full customization, minor customization, and customization from samples or designs.
