Tongwei MCS Certified Solar Panels

Absolutely. Tongwei Solar (TW Solar) is a top 5 global PV manufacturer by shipment volume PV InfoLink (2024), and the world’s largest supplier of solar cells. As a Bloomberg Tier 1 brand, they supply high-efficiency, bankable panels backed by 25–30 year warranties. Their global reputation is built on industry-leading cell production and long-term performance.

While Tongwei is already a top global manufacturer with over 70 GW annual cell capacity, they’ve only recently expanded module distribution into the UK. That means UK buyers can now access Tier 1 quality panels at better value - a strong alternative to more expensive brands.

Tongwei panels offer high conversion efficiencies, typically 20% to 23.5%, using cutting-edge PERC and N-type TOPCon cell technology. This ensures maximum output even in limited roof space or challenging light conditions.

Tongwei solar panels are built to last. Most models come with a 25-year product warranty and a 25 or 30-year performance warranty, with guaranteed output of approx. 84.8% after 25 years.

Yes, Tongwei panels supplied by Alternergy are either MCS-certified or in the process of UK registration. This ensures full compliance for residential and commercial installations, including eligibility for SEG payments and planning exemptions.

Tongwei panels combine Tier 1 quality and global reputation with excellent price-to-performance ratio, high efficiency, and long warranties.

Tongwei panels, including TOPCon and monocrystalline modules, are designed for high efficiency in low-light and variable climates, making them ideal for UK rooftops, ground-mounts, and commercial projects.

Yes, Tongwei Solar panels are an excellent fit for rooftop and agrivoltaic installations, both of which are highlighted in the UK Solar Roadmap 2025. Their high-efficiency monocrystalline modules are ideal for residential rooftops, commercial buildings, and warehouse systems, where reliable output and compact design are essential. Tongwei’s durable, bifacial-ready panels also support agrivoltaic applications, enabling dual land use for farming and solar energy; an approach increasingly encouraged through UK policy and planning reform. Tongwei panels offer a scalable solution for installers working across rooftop, farm-based, and large-scale solar projects.

Alternergy provides local support for all Tongwei panels we supply. In the rare case of a warranty issue, we’ll handle the process directly to ensure a fast and smooth resolution.

Tongwei panels are available through Alternergy, a trusted UK solar distributor. Customers can order directly via our trade portal, with competitive trade pricing, UK stock, full technical documentation, and dedicated support for installers and developers. We offer nationwide delivery, including next-day or scheduled site drops for urgent or large-scale projects.
