All about solar shingles

New technologies to harness solar energy

Solar energy is a key renewable energy source in the energy transition. In the last few years, technologies have emerged that seek to effectively harness solar radiation with the aim of producing electricity.

What are solar or photovoltaic shingles?

Solar shingles, also known as photovoltaic shingles, are an innovative building material that fuses the characteristics of a traditional roof tile with the ability to produce electricity from solar energy.

One of the stand-out innovations is the emerging technology of solar shingles, which is presented as a developing solution with promising potential. These solar shingles are designed to integrate harmoniously into the building structure, offering an aesthetically appealing and efficient way to harness solar energy. However, despite their potential, there remain significant economic challenges that currently hinder their widespread adoption.

These solar panels are designed to blend in with traditional roof tiles, but have photovoltaic solar cells incorporated into their design. They work by converting solar energy into electricity through these solar cells. These cells capture sunlight and transform it into an electric current that can be used in the home or even fed into the power grid.

When fed into the power grid, this additional electricity is distributed and used to supply other consumers in the community. This not only contributes to renewable energy generation at the community level, but can also reduce electricity costs for the owner of the solar shingles.

It's important to highlight that roof tiles with solar panels are an evolving and developing solution. They are expected to improve in terms of accessibility and efficiency as research and adoption of this technology progresses.

Advantages of solar shingles

Solar shingles are an attractive option for people who seek a clean energy source for their homes and businesses. Some of the advantages of photovoltaic shingles are:

Increase in property value

Installing roof tiles with solar panels increases the value of a property by adding a renewable energy source, making the home attractive to buyers.

Decentralized power generation

Solar shingles offer the capacity to generate their own electricity, which contributes to the energy independence of homes.

Subsidies

In some regions there are tax incentives that help reduce the cost of installing photovoltaic shingles, making the investment more affordable.

Durability

Solar shingles on the roof are designed to resist adverse weather conditions, which translates into a prolonged useful life.

Aesthetics

Solar shingles have been carefully designed to blend in with conventional roof tiles without compromising their visual appearance on any building.

Long-term savings

Although the initial investment can be expensive, photovoltaic shingles generate significant savings in electricity costs.

Other solar solutions

Photovoltaic shingle technology is still under development. In the meantime, there are other sustainable alternatives for harnessing solar energy. Some of these solutions are:

1. Photovoltaic solar panels

Photovoltaic solar panels, perhaps the most well known, are devices that directly transform sunlight into electricity. They are composed of multiple interconnected solar cells and are widely used on the roofs of homes and commercial buildings. These panels generate electricity efficiently and can be used both for self-consumption and for feeding electricity into the power grid. Their versatility and efficiency make them an outstanding solution for solar power generation.

We can harness solar energy in two ways through the use of solar panels. The first is self-consumption. Solar self-consumption consists of the installation of solar panels on a residence, business, or property for the purpose of generating electricity for internal consumption. Any excess generated can be injected into the power grid, in some cases, generating income for the owner.

On the other hand, solar communities are projects in which several owners share a common solar installation. These installations can be located in a nearby area and generate electricity that is shared among community members. This allows people who cannot install solar panels on their own roofs to harness solar energy and reduce costs. Join the solar communities near you.

2. Solar water heaters

Solar water heaters harness solar energy to heat water. These systems capture the sunlight and use it to heat a fluid, which transfers the heat to the water used in homes, pools, and heating systems. They are a highly efficient option to reduce energy consumption in the heating of the water, which contributes to both sustainability and energy savings.

3. Solar generators

Solar generators are systems that use solar panels to generate electricity and charge storage batteries. They represent an option to provide energy in places where there is no access to the power grid or in emergency situations. These systems offer a reliable and sustainable source of electricity, making them a valuable solution in a variety of circumstances.

At Repsol, we lead innovation in solar energy, promoting a more sustainable future. When you choose solar energy for your home, you don't just save in your electricity bills, but you also contribute to the preservation of our planet.
