One team for your solar project, from selection to delivery

Why Global Buyers Choose SunCrank

Customized solar panels and complete solar systems, checked and shipped as one compatible package. Tell us the application, the load, and where the system will be installed. We will help you choose compatible panels, inverters, batteries, and protection devices, check them before shipment, and arrange consolidated shipping to your destination. This is for EPC contractors, solar distributors, installers, project developers, system integrators, OEM brands, government and project suppliers, and off-grid solution providers.

One-Stop Solar Energy Solutions

Instead of sourcing from multiple suppliers, get solar panels, energy storage systems, solar lighting power systems, and mounting solutions through one team. ✔ Save sourcing time ✔ Reduce shipping costs with consolidated shipment ✔ Receive a system checked for compatibility before shipment

Customized for Your Market

Every market and every application is different. We provide customization for power, size, shape, voltage, connectors, branding, packaging, and complete solar system design. ✔ Private label ✔ Custom design ✔ Tailored solutions for homes, commercial buildings, desert, coastal, and high-wind locations

Vetted Sourcing, Checked Before Shipment

We work with vetted manufacturers and suppliers. Our role is to select the right products for your project, match them into a working system, and check quality before shipment. ✔ Vetted suppliers, selected for your application and market ✔ System matching and compatibility review ✔ Pre-shipment quality checks ✔ Consolidated shipping in one container where possible We do not claim to manufacture every component. We are responsible for selection, matching, inspection, and delivery as one integrated solution.

Quality You Can Trust

Every shipment is inspected before delivery. Our quality checks follow three stages: 1. Incoming material and line inspection — verification of incoming materials and inline EL / visual scanning to prevent micro-cracks, cell impurities, or physical defects. 2. Outgoing quality control and flash testing — full-capacity power output calibration, insulation safety testing, and structural stress validation. 3. Container loading oversight — standardized, moisture-proof packaging and on-site container loading supervision to reduce transit damage. Certifications are matched per market and confirmed against the product datasheet — see Our Track Record below. ✔ Strict quality control ✔ Supplier certifications matched to your market and confirmed per product datasheet ✔ Reliable performance for long-term outdoor use

Complete Technical Support

We do more than supply products. Our team helps you complete projects faster, with: ✔ Solar system design ✔ PV string design and inverter matching ✔ Off-grid, grid-tied, and hybrid / solar + storage sizing ✔ BOM support and compatibility review ✔ Technical drawings ✔ Installation guidance ✔ Tender documentation support

Global Project Experience

Since 2014, our solutions have been supplied for residential, commercial, industrial, and government projects in more than 150 countries and regions. From small installations to large-scale applications, we support customers with practical, compatible solutions and one point of contact from selection to delivery. ✔ Residential ✔ Commercial ✔ Industrial ✔ Government projects

By the numbers

Our Track Record

Certifications vary by product and by market. Polynet holds no product certifications itself. For each project, we match a supplier whose products hold the certifications required for that market, and we confirm them against the product datasheet before quoting. Tell us the certification your market requires, and we will confirm whether the proposed product meets it.
