In EndeF we are strongly committed to research, development and innovation. This company not only applies current products and solutions, but also intends to develop innovative products that place us at the technological vanguard.

A proof of it is the development of the second-generation hybrid solar panels ECOMESH, with the TIC technology patented by EndeF.

Beyond the already developed products, EndeF provides a wide variety of R&D services oriented to different audiences, both public and private, according to their special requirements.

Because of this, multiple collaborations are commonly conducted between EndeF and universities or advance research centers, such as the University of Zaragoza.


The hybrid solar panel: ECOMESH

Within our product range and together with the thermal and photovoltaic panels, our leading product can be found: the ECOMESH hybrid solar panel, able to produce heat and electricity in a single panel.

  • Reduces the collection surface by 40%
  • Triples thermal output
  • Increased electricity production by 15%

The objective that CloudiFacturing pursues is optimization in production processes and productivity, using simulation and models based on the high performance of the cloud, taking advantage of data in its own advanced analysis, thus contributing to competitiveness and efficiency in the use of resources by SMEs. With this, the aim is finally to promote the vision of Industry 4.0 and the circular economy.

CloudiFacturing trains more than 60 European organizations (many of them, manufacturing SMEs) and supports more than 20 transnational experiments that will be selected, mainly, through two open calls.

Our function within the CloudiFacturing project is the application of advanced computations to improve our manufacturing process.


The project to be financed with NEOTEC revolves around the potential of the ECOMESH panel. There are four key aspects that EndeF has developed during 2016.

  • Study and redesign of the heat collector that incorporates the hybrid panel ECOMESH: improvement in the efficiency and reduction of the weight and costs.
  • Design and construction of a laminating furnace adapted to hybrid solar panels. This equipment is used in the assembly process. At present, it is an oven adapted from the glass industry, in which the panels suffer many thermal stresses. It is necessary to increase the manufacturing capacity with an oven in which the panels do not suffer those tensions and it adapts to the geometry of the hybrid panels, namely an ad-hoc one.
  • Study and construction of a pilot plant for the integration of these panels with heat pump: an optimal solution for the consumer that EndeF wants to launch to the market.
  • Final design and homologation of a monitoring and control system: a new product adapted to the panel that brings the solar reality closer to the consumer.


Low valued energy sources upgrading for buildings and industry uses.

In the “Secure, Clean and Efficient Energy” initiative, it is stated that the most important milestones for such a transformation are the EU’s energy and climate targets for 2030, which are: at least 40% reduction in greenhouse gas emissions compared to 1990; at least 27% for the share of renewable energy consumed in the EU, and at least 27% improvement of energy efficiency and an electricity interconnection target of 10%.

The LowUP Project has a two-fold strategy: on one hand, to target goals and of these climate challenge with a 42 months duration project where innovation will be the core activity, and, on other hand, to successfully present different technological solutions which will enable the participation of low grade thermal energy sources in the energy transition, and improve the efficiency of the Europe Low Exergy systems, not only at building level but also in industrial applications.

Within the LowUP project three different heating and cooling systems will be developed and demonstrated at relevant environment: HEAT-LowUP (low exergy heating system directly fed by solar and sewage water recovered heat) COOL-LowUP (low exergy cooling systems directly fed by renewable and free energy sources) and HP-LowUP (waste heat recovery and upgrading via heat pump.)

The first two systems are focused on the rational and efficient use of low valued energy sources for direct implementation in low-exergy heating & cooling systems for buildings and the third one is focused on the exploitation of low temperature residual energy, wasted with industrial processes, by upgrading them to generate useful heat to be re-introduced in the process.

The project will be implemented using the Acciona thermal lab located in Seville (Spain) where will be emulated different real cases as the industrial process of a water treatment plant, an automotive factory and a retirement house.

CARTIF’s role in the project will be to coordinate the building low valued energy heating and cooling solutions as well as concept and design upgrading via modeling and simulation; control system for building integration; and to develop the Life Cycle Analysis (LCA).


Task 60

This Task will focus on the application of PVT collectors with the aim to assess existing solutions and to develop new system solution principles in which the PVT technology really offers advantages over the classical “side by side installations” of solar thermal collectors and PV modules. Energy  production, competitive cost, safety and reliability of systems are therefore in the scope of the Task.

The objectives of the Task are to:

  1. Provide an overview on the present (2018-2020) state-of-theart of the PVT technology worldwide.
  2. Gather the results and the operating experience made with the systems in which PVT collectors are integrated.
  3. Improve the testing, modeling and adequate technical characterization of PVT collectors in order to enhance (and simplify) the correct inclusion of the PVT technology in simulation programs and planning tools.
  4. Address all types of PVT collectors since the current markets have made no clear choices.
  5. Find more typical PVT solutions beside the two applications which are well known, i. e. regeneration of bore-hole storages and pre-heating of DHW for multi-family houses.
  6. Explore potential cost reductions in the balance of systems, i.e. piping technology and materials, hydraulics, controls etc.
  7. Increase awareness of PVT.
  8. Support the re-start of the PVT industry

Task 60 project is organized by the International Energy Agency (IEA).


EndeF wants to develop the project called “3Gsol” to offer a real and profitable solution to the joint generation of electricity, heat and cold with solar energy. This solution is based on the integration of hybrid solar panels with refrigeration machines.

Given the combined combination of electric and thermal generation of the ECOMESH hybrid solar panels, they are presented as a promising solution in combination with heat pumps or absorption machines, drastically increasing their COP in the first case, or decreasing the problems of excess heat in summer in the second, and ultimately supporting the refrigeration sector that faces a technological challenge when the F-Gas regulation comes into force next year, whose reduction will begin next year in 2018 with a reduction of 37% .
