Freesuns chief executive John Morello said the tiles can be sized to completely replace conventional roof tiles in fiber-reinforced concrete, with three models able to potentially cover 100% of a roof surface, including on complex roof layouts.
Every tile hosts an electrical safety circuit to help prevent fire-risk, the company said, adding the product is manufactured with double tempered glass.
Solaris’ standard tile is a 525mm by 460mm tile which reportedly delivers 154 W per square meter. It costs $299 excluding VAT. Morello told pv magazine, “This value is just an indicative value as the price can change depending on the complexity of the project.” The tile – glossy black with silver lines – is said to be ideal for new-build or renovated structures as it offers a modern architecture style.
The standard tile has been deployed on a 2,200 square-foot residential roof in Colombier, Switzerland, amounting to 28 kW of solar generation capacity and added 32 kW on a 2,600 square-foot residential roof in the municipality of Pully.
The premium model is a 420mm by 400mm product with a slightly lower output of 136 W per square meter. The model is recommended for modern architecture and for the replacement of cement tile roofs.
The (more expensive) matte gray product has no visible lines and could be used to replace slate-style roofs on historic buildings, according to its developer.
The tiles were installed on a small house located in the 18th century Grand Chalet of Rossinière, one of the oldest chalets in Switzerland.
“For such an important heritage property it was critical to preserve the historical context in the appearance of the roof so it remained sympathetic to the site,” Freesuns said. “It was also a challenge to convince the local authorities charged with protecting the heritage of the Grand Chalet to allow solar on the roof of this building.”
The roof of the small house of the historical building now hosts 8 kW of PV capacity across its 600 square-foot roof. The matte tile is also being used on a 168 kW project under development on a 12,900 square-foot roofspace at another historic building in Switzerland.
Freesuns said the tiles come with a warranty which guarantees they will maintain 90% of power output after 10 years and more than 80% after 20 years.
