secretly solar roof

An Italian company is producing photovoltaic roof tiles that completely mimic materials such as terracotta warriors, stones and wood in historical centers and buildings across Europe and are licensed to install solar photovoltaic (PV)
The roof can be complicated.
Unless the solar cells are invisible, the limitations of the aesthetic landscape are often so strict that they become prohibitive.
As a result, many people are trying to hide or embed solar roof panels in a material similar to what is commonly used for roofs, paving stones, or covering blind walls.
For example, Tesla of Elon Musk launched a glass --Layered wooden tile.
Products like this are more or less invisible on the street.
But from a certain height, you can see dark cells, such as the famous Paris roof View, which is an unacceptable idea.
It\'s a small family, Dyaqua.
The state-owned company in Vicenza, Italy, has produced a product called \"invisible solar\", a photovoltaic roof tile that is different from other products on the market.
It immediately triggered prosperity.
Dyaqua inserts photovoltaic cells into polymer compounds that mimic common building materials such as stone or wood, so that solar cells are completely invisible to the human eye.
Giovanni Quagliato said: \"Since we started production a few months ago, we have not only been able to keep up with orders from Italy, but also with orders from France, Spain and the United States . \" Vicenza-
A natural artist who specializes in Epoxy Art finds the secret of making the polymer look completely natural while making them transparent to the light.
This compound can be transformed into any building material, be it Terracotta Warriors, stones, cement or wood. It is non-
Toxic and recyclable, able to withstand high static loads and resist atmospheric agents and chemical solvents.
\"It\'s all about density: it has to be enough to fool the eyes, but not too much, so as not to block the light of the Sun,\" Quagliato explains . \".
A few years ago, he launched an LED light production line called Medea based on the same technology.
He then continued to create photovoltaic systems with the Dyaqua series he launched in collaboration with the Italian National Agency for new technologies, energy and sustainable economic development (ENEA).
\"The principle is the same: in lamps and lanterns, the light comes from the inside and must spread outward, while in photovoltaic tiles, the light of the Sun comes from the outside and must penetrate through the transparent material to reach the solar cell, \"Quagliato explained.
However, it is not easy to apply this theory.
It takes years of effort to achieve the desired focus.
Then, an independent scientific organization tested the efficiency of the prototype.
The test confirmed the impressive performance of 70 peak watts per square meter, about half of the performance of classic photovoltaic modules.
Invisible solar energy on the market is 7 euros per watt, while 1-
Standard PV modules are 2 euros per watt.
\"You have to keep in mind that these are handmade items specifically designed for the historical center: even for regular tiles and roof tiles in the historical center, prices often range from 1 euro to 7 euro, quagliato said.
At present, Dyaqua survives by the production of LED lights.
Photovoltaic products are not economically sustainable because they require a lot of manual work.
So far, no machine has been able to replace the careful hands of humans applying different resin layers at different densities, whether on or below photovoltaic cells, the perfect roof tile has the right curvature.
Creating a flat surface similar to stone or cement is simpler, but it is still a delicate task compared to the industrial production of ordinary tiles or solar panels.
\"In order to speed up production and keep up with demand, we have to invent machines that integrate or replace manual work,\" Quagliato said . \".
Only in this way can mass production be achieved, thus reducing prices and increasing the competitive power of products with large producers such as Tesla Solar Roof.
But Dyaqua lacks money to invest in machines.
Quagliato\'s children Matteo and Elisa launched a crowdfunding campaign on IndieGoGo to try to raise $20,000 to pay for one.
Matteo pointed out: \"The Invisible solar energy is my dream for a healthy world in which technology has the appearance of our natural landscape.
