What are Viridian Solar Panels?

What are Viridian Solar Panels?

Viridian Solar is a UK manufacturer specialising in roof-integrated solar panels. Unlike traditional on-roof systems, Viridian panels replace roof tiles to create a seamless in-roof design. Their current flagship product is the 445 W in-roof panel, designed for high performance while maintaining a sleek, modern look.

Viridian Solar panels are often chosen for new build projects and re-roofing, as they provide both clean energy and an attractive finish. With panels engineered to integrate with popular roof features like Velux windows, the system offers a complete roofing and solar solution in one.

Why Choose Spirit Energy?

How Does the Viridian Solar Panel System Work?

The Viridian Solar system is designed to sit directly on the battens of your roof, rather than in trays like many other in-roof systems. The panels feature an integrated frame that secures them in place, with flashings and gaskets added around and between each unit to ensure the roof remains watertight. The kit is tailored to each project, accounting for the size and shape of the array and features such as skylights. This bespoke approach ensures a neat, durable finish that both generates electricity efficiently and complements the roofline.

How Much Can You Save By Installing In-Roof Solar Panels When Re-Roofing?

Does Viridian Work with Battery Storage?

Do Viridian Solar Panels Work with Battery Storage?

Yes, Viridian Solar panels can be paired with battery storage systems like Tesla Powerwall and Sigenergy. One of our recent installations combined 22 Viridian panels with a 32 kWh Sigenergy battery system, with the panels connecting straight into the battery inverter. In this setup, solar generation powers the home directly, while excess electricity is stored for use later in the day or at night. Any surplus can still be exported to the grid.

Adding battery storage not only improves energy independence but also enhances savings and resilience against rising electricity costs.

The Benefits of Viridian Solar

Viridian in-roof solar panels provide both aesthetic and practical benefits. By replacing roof tiles, they save on roofing materials and labour, which is particularly valuable for premium finishes such as slate.

The system naturally protects against birds nesting under panels, eliminating the need for additional bird-proofing. With no exposed mounting hardware,

Viridian panels also avoid issues of wind uplift, making them ideal for homes in exposed or coastal locations.

Beyond the technical advantages, they deliver clean, renewable energy while maintaining a sleek roofline that enhances the property’s appearance and value.

FAQ's

Yes, Viridian solar panels integrate with Velux windows and skylights.

Viridian solar PV panels are manufactured in a factory near Cambridge in the UK.

Viridian Clearline Fusion panels provide enhanced wind‑load resistance—certified to withstand more than double the wind force compared to competitors, especially important for exposed roofs or coastal zones.

The Disadvantages of Viridian Solar PV Panels

While solar systems like Viridian Solar offer a premium in-roof solution, there are some limitations to consider. In-roof panels tend to run slightly hotter than on-roof systems, which can reduce efficiency during peak summer months, though the annual impact is small. Viridian panels are only available in set sizes, limiting design flexibility compared with on-roof systems where portrait and landscape orientations can be mixed. The range is also narrower, with the 445 W panel being the main option. For homeowners prioritising maximum output or flexibility, an on-roof system may provide more choices.

Viridian ArcBox

Viridian’s ArcBox is a safety feature designed to protect your home from the rare risk of electrical arc faults at solar panel connections. It is a small hinged enclosure that houses the MC4 connectors at the end of each string.

By containing the connection in free air with built-in ventilation and drainage, ArcBox prevents overheating and moisture build-up. In the unlikely event of an arc fault, any fire is safely contained within the box, protecting the rest of the roof. We fit ArcBox as standard with every Viridian Solar installation for added peace of mind.
