Eternit announced the first photovoltaic solar tile developed in Brazil, approved by Inmetro (National Institute of Metrology, Quality and Technology).

Eternit Solar allows us to capture solar energy and transform it into electrical energy that you can use in your life. It was presented during Intersolar South America, the largest trade fair in Latin America.

Eternit was founded 80 years ago and has always followed global trends in sustainable technology.

We are developing the industrial process for the large-scale manufacture of this first generation of photovoltaic tiles which passes Inmetro certification tests, which represents an important step for our company. We have been working on this project for a year and now we present the first approved concrete model to the civil construction market, with different color and finish options, and photovoltaic cells integrated into the material. We also have another line, this one in final stages of development for future approval, using fiber cement tiles. The products will soon be available to consumers.

Luís Augusto Barbosa, President of Eternit.

Luís António Lopes, head of the New Business Development area, says that part of the components for photovoltaic panels are already available on the market, such as solar cells and inverters.

The great novelty of Eternit solar tiles is that all silicon photovoltaic cells are applied directly to the cement.

What exists today on a large scale are photovoltaic solar panels whose models must be installed on the roofs. The new photovoltaic tile has enormous potential to become one of the main activities of the Eternit group, because it is a disruptive product, with high added value, easy to install, safe and less expensive than current solutions. In addition, it is able to generate the electricity needed by homes and other commercial and industrial sites competitively in terms of performance and efficiency, based on an aesthetically advanced model.

Each Eternit solar photovoltaic panel produces 9.16 W, with dimensions of 365 x 475 mm.

A single tile per month can produce up to 1.15 kWh. It is estimated that this technology can save the consumer between 10% and 20% on the total cost of purchasing and installing photovoltaic panels compared to the total cost of solar panels already installed.

The payback time of the investment is shorter than that of the solar panel system. Thus, the investment is recovered in 3 to 5 years, depending on the system installed.

For a common house, the number of tiles needed depends on the amount of energy to be produced, location, tilt and orientation relative to the sun, among other factors.

As an example, a small house can have between 100 and 150 photovoltaic tiles, while the larger ones can have between 300 and 600, the rest of the roof being filled with common tiles, completed with finishes such as tops, sides , points of the same model. and material with perfect fittings.

Eternit understands that by integrating photovoltaic generation into its tiles, it combines innovation and sustainability in a new product, and is taking an important step in an increasingly conscious consumer market. The market potential is reflected in the figures, as in 2018 alone, more than 35,000 PV systems were installed and connected to the grid and in the first half of 2019, 32,000 PV systems have already been installed.
