The photovoltaic cells installed directly on the tiles capture solar energy, replacing traditional solar panels. The construction materials manufacturer and responsible for the technology expects that its commercialization will only begin in the second quarter of 2021.
Each solar tile from Eternit Solar produces 9.16 watts and measures 365 x 475 mm. The average monthly production capacity of a single tile is 1.15 Kilowatt-hours per month (kWh/month). The concrete models have two finish options and five colors: graphite gray, pearl gray, straw ivory, colonial beige, and red.

Fortescue announces a radical shift by replacing diesel with a system featuring 1.2 GW of solar energy, 600 MW of wind energy, and up to 5 GWh in batteries, a giant project that could save $100 million per year and transform heavy mining into one of the largest 100% renewable operations in the world by 2028.
According to the commercial director of Grupo Eternit, Rodrigo Inácio, the estimate is that the concrete tile capable of producing solar energy will allow the consumer to save between 10% and 20% on the total cost of purchasing and installing photovoltaic tiles compared to solar panels installed on regular rooftops. The return on investment occurs between 3 to 5 years, depending on the system.
According to Eternit, a small residence needs about 150 tiles, while larger houses should use around 600 solar tiles. The rest of the roof can be covered with regular tiles.
The company states that, once installed, the system can generate returns in a period of 3 to 5 years.
A select group of clients will have early access to the new technology, which will be produced in a factory in the interior of São Paulo, belonging to Grupo Eternit.
