Adding colour to design aesthetics of in-roof solar

Cost and efficiency matter, but the introduction of multiple colour choices for integrated solar roofs helps mainstream renewable technologies by meeting rising demand for both aesthetics and compliance.

Estonian manufacturer Roofit.Solar has introduced a new range of colour options tailored for architects, developers, and heritage restoration projects or sensitive urban sites across Europe.

The offerings — in red, green, and grey — expand design possibilities for solar integration in buildings where traditional black panels may not be suitable due to regulatory, aesthetic or architectural requirements.

Available across Europe and the UK in the high-efficiency Velario Slim and NuClick product lines from Roofit.Solar, the new colour options include: Iron Grey; Pale Green; and Copper Brown.

The palette reflects traditional roofing colours common across Europe: terracotta red tiles in Southern and Central regions; weathered green copper on historic public buildings such as Hildesheim Cathedral, in Germany, or Kronborg Castle, Denmark; plus dark grey tones prevalent in Northern architecture.

The options add design flexibility and are particularly relevant for renovation projects, public buildings or structures under heritage protection, where visual harmony and material authenticity are critical.

Designed to meet customer demand

Until now, Roofit.Solar’s solar roofs were available exclusively in Jet Black. However, growing demand from architects, municipalities, and developers has prompted the introduction of new colour options.

Colour helps combine aesthetics and compliance, says Andres Anijalg, CEO and co-founder of Roofit.Solar:

“These colours are new to our portfolio, but demand has been strong for years — especially for red and green, which are integral to Europe’s traditional roofscapes. They allow us to offer an aesthetic solar solution that not only meets visual expectations but also complies with preservation requirements in heritage contexts.”

Building regs and heritage requirements

The integrated solar roof is a true building material, not an add-on.

According to Roofit.solar, therefore, the product is uniquely suited to replace traditional metal roofs with a seamless energy-generating alternative. This makes it one of the only viable solar options for buildings in protected zones, or those requiring historically accurate restorations.

Design flexibility is especially relevant given the launch by the European Commission of its REPowerEU Plan, in 2022. This geopolitically driven initiative mandates increased solar deployment, even in areas where aesthetics and building codes often conflict with traditional solar options.

The new next-step products will therefore help future solar adoption in Europe, concludes Andres Anijalg:

“Solar must be accessible not only technically, but visually. These new options allow property owners, cities and developers to meet sustainability targets without compromising architectural integrity.”

Fastest-growing energy startup

Founded in Estonia in 2016, Roofit.Solar is a leading provider of building-integrated photovoltaics (BIPV) that combine renewable energy production with Scandinavian design and high-quality materials. The two-in-one solution opens up the possibility of installing metal roofs and facades with integrated solar PV systems on new and existing properties and facilities, including heritage and listed buildings.

The company is already active in more than 25 countries and, in 2024, was listed as the fastest-growing solar energy startup and 12th overall on the Sifted 30: Eastern Europe and the Baltics Leaderboard.
