First EASY ROOF INTEGRATION (ERI) Project in Spain
A wonderful renovated house with all the improvements on the roof side: insulation system, integration of photovoltaic panels and high quality roof tiles, thus achieving an aesthetic and functional integration.
Last June saw the first installation of the Easy Roof Integration (ERI) photovoltaic panel integration system in Spain. An ideal solution for photovoltaic installations integrated into the roof plane, so that they do not affect the watertightness or safety of the roof.
This project consisted of an energy refurbishment of a single-family house in Madrid. For the renovation work on the pitched roof, after removing the old tiles and cleaning up the support, the property and the technicians responsible for the project selected the BorjaSAT140mm thick prefabricated panel system to insulate the roof of the house.
BorjaSAT is an external roof insulation solution, which forms a covering layer without thermal bridges, designed to be installed easily and without the need to set out the battens for fixing the tiles. With the 140mm panel, a transmittance of 0.22 W/m2k was obtained, a value well above what is required by the Technical Building Code in this climate zone.
With the thermal insulation solved, the other problem of this refurbishment was to be able to install a photovoltaic solar collection system that would not affect the design of the house so much. For this reason, the ERI integrated solution was chosen, where the photovoltaic panel is fixed on a system of watertight frames to the structure of the roof system’s battens.
This solution, in addition to improving aesthetics and integration, avoids future pathologies, such as leaks due to poor installation or expansion of the coplanar metal structures that are usually installed. It also eliminates the possibility of birds or rodents nesting under the panels, with the consequent damage to the wiring and aesthetic impact due to dirt.
Finally, in the event of storms with strong winds, as they are anchored and integrated into the plane of the tile, the panels cannot be torn off by strong gusts, as has happened on numerous occasions with installations superimposed on the roof, which constitute a danger to the integrity of pedestrians in the area.
To complete this refurbishment, the tile chosen was the TB-10 TECH EntrepinsS-Interlocking roof tile. A large roof tile model manufactured by Tejas Borja with digital ceramic printing; an aged finish, created from HD photographs on real old tiles, giving the appearance of a recovered tile to a state-of-the-art product.

Answers to 10 frequently asked questions about solar roof tiles installation
Answers to 10 frequently asked questions about solar roof tiles installation
Currently solar power is one of the most sustainable renewable energies, one which enables electricity to be generated in the same placeit is going to be used to supply energy for lighting, heating and refrigeration.
There are numerous advantages to having a photovoltaic installation at your home or business. In addition to reducing electricity bills and improving energy efficiency, producing energy via a solar installation contributes to the fight against climate change.

If you are considering buying a solar installation which makes use of the roof surface, Tejas Borja offers you an integrated, reliable solution. However, before making the decision to install the photovoltaic system, you must follow these steps:
Research relevant requirements and legislation.
Choose your preferred type of self-consumption.
Check the viability of a solar installation.
Select quality materials.
Hire qualified personnel.
Carrying out a photovoltaic installation on your roof is an important decision, as it affects both the building and the efficiency of the energy collection. In this post we have put together 10 frequently asked questions, whose answers you should know before making such a significant decision.
Q1. What are the benefits of solar energy?
When you take the decision to have a solar energy capture installation integrated into the roof of your property, you will reduce your electricity bills and protect yourself against future increases in the cost of electricity in the energy marketplace. How much you can save with a solar installation depends on various factors:
Your electricity tariff. If the tariff in your area is higher than elsewhere, you will save more money in less time.
Energy policies in your area. In areas where there are government policies to incentivise the generation of solar power, you could save even more.
The price of electricity. The price of electrical energy can be unpredictable. Any calculation of potential savings from a photovoltaic installation using solar tiles will be based on a price estimation. However, as it is likely that electricity prices will continue to rise, savings will also continue to increase year on year.
The solar tile installation capacity and energy consumption. Although a responsible consumption of energy is always recommended, depending on the amount of electricity you produce using your solar installation, you may never have to pay electricity bills again or may reduce your bills to such an extent that energy payments are never again a significant part of your household budget.
Choosing a solar installation is a wise decision regardless of the property’s location. When you decide to have a solar installation, your electricity costs become minimal and stable.
Q2. What are the environmental benefits of solar energy?
Similar to other renewable sources of energy, solar energy has many environmental and general health benefits. Firstly, it results in a considerable reduction in the emission of greenhouse gases, making a significant contribution to the fight against climate change. Moreover, it prevents the emission of other pollutants which can cause health problems, which would otherwise be generated during the production of energy through conventional methods.
Q3. What impact will a solar energy installation have on my house/property?
A solar energy system will increase the value of a property considerably. This increase will be greater when the installation is owned rather than rented. For comparison, a solar installation will add more value to a property than the renovation of a bathroom or kitchen, and even more if the solar system is integrated into the building.
Q4. How do the solar tiles work?
Solar tiles, like other solar power products (e.g. solar panels), capture light energy from the sun during the day and convert it into direct current. Houses and buildings usually use alternating current. The direct current from the solar installation passes through an inverter and is transformed into useable alternating current. Now the electricity can be used or consumed, or ceded/sold to the national power grid. There is also the option of installing batteries to store any excess energy generated during the day so it may be consumed during periods when it is not sunny.
Q5. Will my solar tiles produce energy on days which aren’t very sunny?
The amount of electricity generated depends on the amount of sunlight which reaches the tiles. There will be a small drop in the level of power generated if the tiles are shaded and they will not produce energy at night. However, using the latest technology in the manufacture of photovoltaic products, denominated by the acronym , we can guarantee we are offering the most effective technology for generating solar power in shaded areas. Using this technology we obtain high performance, highly-efficient solar cells which are also environmentally friendly as they are made from copper, indium, gallium and selenide and are free of cadmium and lead.
Q6. What happens if the solar tiles get covered in snow?
Solar tiles convert solar energy into electricity. If they are totally covered in snow, they will not be able to produce electricity. Thanks to the structural resistance of each solar tile and the way they are installed, any snow which may settle on them shouldn’t cause any structural damage to the product. Thanks to the roof slope and the sleek surface provided by the solar tile glass, snow will slide off the tiles easily or be simple to clean off.
Q7. Are solar tiles suitable for isolated properties which are not connected to the national power grid?
It is more common to find photovoltaic installations connected to a power grid, either because the property gets power from the grid at night when the installation does not produce electricity or because the owner of the installation wants to sell any excess energy it generates. However, an installation with solar tiles is suitable for isolated properties which are not connected to the power grid, but the installation must always include a system of batteries to store the energy generated.
Q8. If I have solar tiles will I still receive electricity bills?
If the photovoltaic installation with solar tiles does not include a system of batteries to store energy and the property is connected to the national power grid, you will continue to receive electricity bills from the public grid, but you can reduce these bills significantly with a solar tile installation which adapts to your energy needs.
Q9. Will solar tiles work during a power cut?
If the installation is isolated from the power grid you can guarantee a supply of electricity during a power cut. However, if the installation is connected to the power grid and does not include a system of batteries, due to the characteristics of the inverter, during a power cut your installation will turn off automatically to prevent anyone working on the installation from receiving an electric shock.
Q10. What maintenance does the installation require?
The solar tiles are manufactured using the best materials and components available for this purpose. With a ceramic or aluminium base, they are ideal to guarantee the watertightness of a sloping roof.
Over the entirety of their useful life, the solar tiles require minimal maintenance and often the glass does not even need regular cleaning. For more information, we recommend you consult the ceramic solar tile manual [here].
