Solar tiles or photovoltaic panels: which one to choose for your home?

In recent years, the topic of renewable energy has increasingly entered Italian homes. Coupled with the rising energy costs and the growing sensitivity towards sustainability, more and more families are wondering how to produce the electricity needed for their domestic needs.

In this scenario, there are no shortage of available solutions: from traditional photovoltaic panels to the more recent solar tiles, the offer is continually evolving. But which technology is worth choosing? One focuses on efficiency and affordable price, while the other emphasizes aesthetic integration and architectural harmony. In this article, we will analyze both options in detail, comparing them from every point of view: costs, yield, durability, installation, and visual impact.

What are solar tiles

Definition and functioning

Solar tiles, also known as integrated photovoltaic tiles, are a solution that combines the traditional function of roof covering with the ability to produce electricity thanks to incorporated photovoltaic cells. In practice, each tile becomes a small solar module capable of converting sunlight into electricity.

Unlike traditional panels, they are not installed on top of existing tiles but completely replace them, making them virtually invisible from the outside.

Advantages of solar tiles

• Aesthetic integration: the main strength is discretion. Solar tiles blend with the rest of the roof without altering its appearance.

• Ideal solution for historic centers: often in these areas, panels are not permitted due to landscape constraints. Thus, tiles represent a valid and respectful alternative.

• Architectural harmony: those who do not like the 'industrial' effect of panels may appreciate this more elegant solution.
  
  
  

Limitations of solar tiles

• High cost: the price ranges from €1,000 to €2,500 per square meter, about 3-4 times higher than panels.

• Lower yield: the active surface of a tile is smaller than that of a panel, leading to lower energy production.

• Long payback periods: on average, it takes 15-20 years to recover the initial investment.

What are photovoltaic panels

Definition and functioning

Photovoltaic panels are the most widespread and well-known solution for producing electricity from solar energy. They are modules that, thanks to photovoltaic cells, convert sunlight into direct current, which is then transformed into alternating current by an inverter for use in the home.

Advantages of photovoltaic panels

• Accessible price: the cost ranges from €200 to €800 per square meter, significantly lower than tiles.

• High efficiency: the energy yield is greater, allowing the production of more energy per unit area.

• Fast economic return: within about 10 years, the system pays for itself through savings on bills.

• Widespread and reliable: this is a consolidated technology, with a broad network of qualified installers and maintenance providers.
  
  
  

Limitations of photovoltaic panels

• Aesthetic impact: the roof appears different, which may not appeal to everyone.

• Space and orientation: they require clear and well-exposed surfaces to perform optimally.

• Architectural integration: they do not always match the aesthetics of historic or prestigious buildings.

Direct comparison between solar tiles and photovoltaic panels

Prices and installation costs

• Solar tiles: between €1,000 and €2,500/m².

• Photovoltaic panels: between €200 and €800/m².

The gap is evident: solar tiles can cost up to four times more.

Energy yield and performance

• Solar tiles: lower performance, necessitating cover of a large part of the roof to produce significant quantities.

• Photovoltaic panels: optimized to capture energy efficiently, even on smaller surfaces.

Payback periods

• Solar tiles: 15-20 years.

• Photovoltaic panels: about 10 years.
  
  
  

Durability and maintenance

• Solar tiles: 20-30 years of useful life.

• Photovoltaic panels: 25-35 years.
  
  
  

Aesthetics and visual impact

• Solar tiles: virtually invisible, perfect for historic centers.

• Photovoltaic panels: now also available in an all-black version or with flush installations, more elegant than in the past.
  
  
  

Installation and bureaucratic procedures

Who can install solar tiles

The laying of the tiles is similar to that of traditional ones: a roofer or a plumber can handle it. The electrical connection, however, requires a qualified electrician.

Who can install photovoltaic panels

It is necessary to contact certified installers who can guarantee safety, efficiency, and compliance with regulations.

Incentives and regulations

To access tax deductions and bonuses (such as the 50% deduction or the Superbonus, when active), it is mandatory to contact companies with specific certifications (RGE).

When it is convenient to install them

• Solar tiles: more suitable for new constructions or complete renovations.

• Photovoltaic panels: ideal for both new buildings and existing roofs.

Which solution to choose for your home

When to prefer solar tiles

• In the presence of landscape or architectural constraints.

• When aesthetics is the absolute priority.
  
  

When to choose photovoltaic panels

• If the goal is economic savings.

• If the objective is to reduce electric bills as quickly as possible.

Conclusions on the comparison between solar tiles and photovoltaic panels

Ultimately, solar tiles represent an interesting solution especially where aesthetics or landscape constraints are a determining factor. However, their high price and lower yield still limit their spread.

Photovoltaic panels, on the other hand, remain the most rational choice today for those seeking a concrete economic return, efficient energy production, and an immediate contribution to the ecological transition.

Technology is evolving rapidly, and it is not excluded that in the future, solar tiles may become more accessible. For now, however, those wishing to invest in renewables find panels to be the most convenient, balanced, and effective solution.

FAQ on solar tiles and photovoltaic panels

What are solar tiles?
They are tiles that integrate photovoltaic cells and allow for electricity production in addition to covering the roof.

How much do they cost compared to panels?
Solar tiles cost from €1,000 to €2,500/m², while panels range from €200 to €800/m².

What is the yield of solar tiles?
It is lower than that of panels: more tiles are needed to achieve the same energy production.

How long do they last?
Solar tiles last about 20-30 years, photovoltaic panels 25-35 years.

When is it beneficial to choose solar tiles?
When aesthetics is a priority or in the presence of architectural constraints that prevent the installation of panels.
