Born in 1985 as a company engaged in the construction of single-family homes, buildings, civil works and remodelling. In 2005 they realized that the sector needed to rethink its model due to the effects of climate change and the overexploitation of natural resources, opening the renewable energy division that year to install solar plants and wind farms all over the world. As a result of this experience, more than 10 years ago they began to manufacture and commercialize structures for photovoltaic and thermal installations, in aluminium, galvanized steel and concrete. A world in which they are true specialists.
Along with photovoltaic panels and inverters, which are the essential components of any solar installation, there is a whole world of structures, materials and designs that are underneath the modules. Sometimes they are not seen, so they can go unnoticed by ordinary mortals. But the professionals of the sector know well that the role that these supports play is key. For this reason, in recent years the number of companies working on this type of structure has grown, from the simplest fixing elements to the most complex solar trackers. And important R&D resources have been invested in all of them. With the same final objective: to lower the cost of solar energy through cheaper, more efficient, easier to install and more durable systems.
The Valencian company Ennova has been passionately dedicated to the search for the most efficient solar structures for more than a decade. They have long experience in the renewable sector, where they have carried out engineering and construction (EPC) work on countless projects, both with wind farms and photovoltaic plants. In Spain and half the world. Ennova is also a consummate specialist in the design, manufacture and marketing of solar structures. For both photovoltaic and solar thermal.
They work with different materials: aluminium, galvanized steel and concrete. Each of them with its own characteristics, which make them more or less suitable for different applications. In recent years they have been continuously investing in innovation, knowing that supports also play a key role in the spectacular drop in prices that photovoltaic solar has starred in in recent years.
‘Vela’, the latest innovation
José María Santacreu, Ennova’s CEO, explains to Energías Renovables that “the latest of our developments is a concrete support that we call ‘Vela’. Among its fundamental characteristics is its aesthetics, which we consider important and, above all, the optimization of the space that is achieved with it ”. The range of this type of supports called Ennovabloc has a great variety of angles. It starts with a completely flat support (0 degrees) and goes through others of 5, 10, 15, 20, 25, until it reaches 30 degrees. All of them are used to position the solar module horizontally. But they also have a 20-degree bracket for vertical module installation.
“Currently we have launched three new models with which we form what we call ‘Velas’. We manufacture three different models: Vela of 5º up to 6 rows deep, Vela of 10 ° up to 5 rows deep, and Vela of 15 ° up to 3 rows deep. The peculiarity of this product is the optimization of space since it is not necessary to keep the shadow distance between the rows ”, points out Santacreu.
At Ennova they insist that “our concrete supports are made of highly durable materials. In addition, the installation is simple and intuitive, no assembly plans are needed since the module is fastened with four clips and four screws, which contributes to lower product costs without affecting safety ”. The weight of Ennova’s concrete supports varies between 20 and 76 kg, and is capable of withstanding winds of up to 150 km/h.
The concrete support factory is in Ondara (Alicante). From there, the company’s products are distributed to half the world. Both concrete supports and metal structures. “Currently, more than 25 people work at Ennova to provide the best possible service. In the factory of metal supports we have a continuous stock to be able to cover the needs of our clients at any time. And in the concrete support factory, we have to produce continuously, we work six days a week due to the success we are having with the product ”, says José María Santacreu.
Aluminium, steel and concrete
Ennova manufactures and markets supports and structures for photovoltaic and thermal installations with three different types of materials: aluminum, galvanized steel and concrete. Do they have different uses? Are they recommended for different types of installations?
Ennova has specialized in concrete structures for photovoltaics, although it also manufactures aluminum and galvanized steel supports.
José María Santacreu, CEO of Ennova, explains these differences. «Aluminum structures are advisable on tile roofs and in industrial buildings where the roofs are made of sheet metal, sandwich panel, etc., since they are anchored to the roof and their weight is minimal».
Instead, «galvanized steel structures are used more in solar farms.» Ennova manufactures them in three models: galvanized steel, hot galvanized steel and magnelis coated steel (which offers greater resistance to hard weather).
Finally, there are the concrete supports, «which are beginning to be introduced in solar gardens since it has been proven that they are very resistant and, above all, inexpensive». They are also placed on flat roofs due to the speed of assembly and durability, since this type of concrete becomes harder the longer time passes ”. The weight of Ennova’s concrete supports varies between 20 and 76 kg, and is capable of withstanding winds of up to 150 km/h.
Advantages of concrete supports
Every day they are used more in solar gardens and flat roofs. The reason is simple: concrete supports offer many advantages.
- Fast: it reduces in time and materials the installation of solar panels on roofs or surfaces. Each bracket includes two staples and two screws. You do not need anything else, no rails or anything else to complicate the assembly.
- Simple: easy to install, no foundation or anchoring required. The supports have a weight that can be moved without the need for machinery, it can be easily moved and handled by two people.
- Economic: its price is lower than any other type of media.
- Durable: one of the characteristics of the concrete used in these supports is that the more time passes the more it hardens.
- Efficient: the aim of this product is to keep the solar module in the correct position and to withstand inclement weather. This is how the best result is achieved with this innovative, exclusive and sustainable product.
- Development of renewable energies: it is the perfect support for the new solar era.
