Fotovoltaica tetuan

Between the end of November and the beginning of December 2023, our international training team was on a mission in Tetouan to boost the energy transition in Northern Morocco through the transfer of technical skills to the municipalities of Tetouan, Chefchaouen, Mdiq, and Martil.


The project aims to contribute to the energy transition process, working on two main lines of action:

  • Strengthening the capacities of technicians from the 4 municipalities in photovoltaic energy.
  • Promoting an exchange of good practices in energy transition among municipalities, focused on both individuals and companies.

Currently, the municipalities of the Tangier, Tetouan Al Hoceima region face the challenge of improving their energy management in terms of savings and efficiency. The project planned capacity-building activities for municipal technicians from four municipalities in the region and members of the ANMAR Federation.

In the training sessions, various aspects were covered such as the preliminary evaluation of solar installations, as well as the assembly, installation, and maintenance of these systems.

Furthermore, an exchange of good practices in renewable energy and energy efficiency among municipalities associated with ANMAR was promoted, marking an important step towards the region’s energy sustainability.

Originally, the training was planned for a single photovoltaic installation. However, this initiative expanded to include two installations, aiming to strengthen the knowledge of local technicians, as well as the presence of renewable and local energy sources in public buildings. Theoretical and practical sessions were conducted, including visits to municipal buildings, reporting, and assembly and commissioning work for the two photovoltaic systems at two dependencies of the Tetouan City Council.

These predominantly practical trainings were especially valuable for municipal technicians, who already had a foundation in electricity and needed to expand their specific knowledge in terms of photovoltaics.

The participants, technicians from various municipalities in the area, were the protagonists of this training project. This diversity enriched the experience, allowing an exchange of knowledge and experiences among municipalities. The activities focused on Tetouan, but the project’s impact is expected to extend throughout the region.

A notable aspect of this project was the use of local Moroccan suppliers for the purchase of materials, a decision made to contribute to boosting the national economy of the sector and its autonomy. Additionally, collaboration with the local partner ANMAR was essential for the coordination and success of the project.


This project was funded by Barcelona Solidaria, reflecting a strong and productive bond between Spain and Morocco in terms of sustainable development. The ultimate goal of this initiative was to train Moroccan technicians in photovoltaic technologies, with the vision that these projects could be replicated in other parts of the country.

This transfer of knowledge is expected to have a lasting impact, not only in reducing energy dependence but also in promoting regional autonomy and sustainable development.

Why should we install solar hybrid system?

Why should we install solar hybrid system in Africa?


The Role of Batteries in Solar Hybrid Systems:

In recent years, electrochemical storage systems have emerged as significant players in the energy transition, alongside renewable sources. Unlike other conventional storage systems such as mechanical, thermal, or chemical, electrochemical storage offers several advantages, including high energy and power density, competitive market prices, and the ability to support continuous charge and discharge applications. Due to their scalability and flexibility, electrochemical batteries have become ubiquitous in our daily lives, powering portable appliances ranging from mobile phones to tablets or laptops. It comes as no surprise that even the automotive sector is transitioning from combustion engines to electric motors, coupled with electrochemical batteries.

In the photovoltaic (PV) sector, batteries have been widely used for the past decade to store excess energy produced by PV panels during sunny hours and utilize it during nighttime. The decision to shift power production to the night can be motivated by various factors, depending on the specific system in place.

In on-grid systems, both at the industrial and residential levels, most installed PV systems do not include batteries. The reason behind this lies in the cost implications. Shifting excess solar energy to the night hours leads to an increase in cost per kilowatt-hour (kWh) and an extended payback period. Providing quantitative examples is challenging as it depends on factors such as electricity bills, scheduled costs, battery prices, and battery capacity. According to our experience in the sector, to double the self-consumption through hybrid system we move from 4-5 years of Pay Back Time, with only the PV, to 9-10 years. For this reason, the majority of the installation is known as “0-injection” or “self-consumption,” where the peak production of the PV system matches the peak load demand.

Addressing Reliability Challenges:

However, if the local grid is unreliable and forces consumers to endure frequent power outages, using batteries becomes a more cost-effective and environmentally friendly solution compared to relying on diesel generators as backups. Industries and hospitals, for instance, benefit from integrating batteries into their systems as it ensures a higher degree of independence from the grid, resulting in a more stable and flexible energy supply. Several situations in Africa have demonstrated the critical need for battery integration, as hospitals were unable to operate in surgical rooms due to grid outages and temporary unavailability of diesel fuel for generators.

Moreover, powering your appliances with your own produced power also has a great advantage in terms of power quality and security. The first is crucial to prevent client appliances, which may be very costly, from being subjected to fluctuating grid power and thus getting spoiled over time. The second improves the resiliency of the industry or hospital in reacting to increases in fossil fuel prices or political instabilities.

Off-Grid Systems:


In the specific case of off-grid systems, batteries assume a pivotal role, offering a practical and indispensable solution. Their integration with photovoltaic (PV) technology becomes paramount to ensure an uninterrupted power supply 24 hours a day. These systems go beyond mere economic optimization and are designed to fulfill specific objectives. Depending on the application, the battery can be appropriately sized to meet the load requirements for two or even three consecutive days. Given the unpredictability of solar resources, these systems are consistently hybridized with small diesel generators as a contingency measure during extended periods of rainfall.




Looking Ahead:

In the next blog, we will enter into detail about the available types of batteries (lead-acid, lithium ion, flow batteries …)  discussing which ones are preferred in one case and which in the other. Since the importance of storage in the electrification of the production and consumption sectors is well-known, there are always more and more emerging technologies entering the market. We will go through the most popular ones, describing their pros and cons in commercial and industrial applications.

Casa de Gaiato and its Commitment to Solar Energy

Casa de Gaiato and its Commitment to Solar Energy


Savings in electrical costs and Training for the new Generations

In the heart of Mozambique’s Maputo province, Casa do Gaiato (CoG) has been a beacon of social support for rural communities for more than three decades. This non-profit organisation, located in the Boane district, has provided a wide range of vital services, from food to education, to orphaned children and needy families in neighbouring villages. With one of the largest and most successful schools in the region, CoG not only provides primary and secondary education, but also provides child pickup services and social support to families.

However, since its inception, this institution has faced a major challenge: the lack of an affordable and reliable electricity supply. As one of the few entities in the area connected to the national grid, CoG has had to bear high electricity bills and, consequently, a financial burden that has reduced its capacity for self-sufficiency. This situation has forced the organization to increasingly depend on external sources of funding to continue its community activities and projects.

But the problem doesn’t end there. The instability and low quality of the electricity supply have had a direct impact on CoG’s daily operations. From the interruption of activities to the frequent repair or replacement of machinery and appliances, the organization has had to resort to expensive and environmentally unsustainable diesel generators.

energia solar_cdg

This energy crisis is not an isolated CoG problem; It is a reality that affects the entire surrounding community. The need for a clean, affordable and reliable source of electricity was more urgent than ever, not only for the organization, but also for the families who depend on its services.

This initiative aims not only to alleviate the financial burden of the organization by installing a photovoltaic solar system of 42.8 kW and 40 kWh of storage capacity, but also to train the next generation of renewable energy technicians.

The first phase of the project has focused on reducing CoG’s electricity bills, which have been a significant obstacle to its self-sufficiency. With the use of batteries for energy storage, the organization hopes to establish a partially independent power supply, freeing up resources for other community projects.

In a strategic decision that reflects its sensitivity to the needs of the community, Casa do Gaiato (CoG) has chosen to prioritize the residential area in the event of network blackouts. 40 kWh backup batteries are connected exclusively to this area, allowing a longer power supply in critical situations. This choice highlights the humanitarian approach of the organization, which considers the residential area as the most critical compared to the productive area.

To ensure the success of the project, CoG has worked closely with us as an engineering cooperative specialized in renewable energies. Since the award of the contract, both parties have closely monitored the activities carried out by the subcontractor, holding regular biweekly meetings until the completion of the project.

Formació CdG_:Azimut360

But this initiative goes beyond the simple installation of solar panels and batteries. The project in CoG is not only focused on short-term solutions. We understand that the sustainability of the installed system also depends on the training and education of the people who will take care of it. For this reason, an educational component has been incorporated into the project, offering theoretical and practical training  in photovoltaic solar systems to young people who reside in its facilities. This training is not limited to CoG residents; it also extends to young people from neighboring villages, with the assistance of the Fundação Encontro.

That is why we think that the impact of this initiative could be transformative on several levels. This is not only the first project of its kind in the region, but also serves as a model for future programs in the field of renewable energy. Through collaboration with local authorities, CoG and the Fundação Encontro aspire to make this initiative a starting point for a green energy revolution in the community.

That is why the main objectives of the plan are doubly impactful: on the one hand, to provide CoG with a more affordable and sustainable electricity supply, and on the other, to train a new generation of professionals in the field of renewable energies. This is a gamble for the future that could be game-changer not only for CoG, but for the entire region.


With an estimated annual saving of €3,500 in electricity bills and an educational impact that extends beyond its classrooms, Casa do Gaiato (CoG) is establishing a new paradigm in the use of renewable energies and education in Mozambique. This pioneering project has not only improved the financial sustainability of the organization, but has also opened up new learning avenues and job opportunities for young people in the community.

During the three months since its implementation, the photovoltaic installation has proven to be a resounding success. The annual saving of €3,500 is equivalent to the cost of university studies for three students, a significant contribution to CoG’s self-sufficiency. In addition, the backup system has been crucial in keeping operations uninterrupted, even during network blackouts that previously paralyzed the organization’s activities.

But the project goes beyond numbers. In the words of Arlindo Gabriel Baptista, professor of physics and computer science at CdG, this initiative has enriched the school curriculum, allowing him to introduce discussions on renewable energies in class. Baptista hopes this experience can lead to a vocational training course in photovoltaics at the school.

Rosa Francisco Anakondia, one of the students who participated in the training, reflects the transformative impact of the project. At the age of 24, Rosa has discovered a passion for renewable energy and aspires to a career in this rapidly expanding field. “I learned that it’s never too late to learn something,” says Anakondia, also highlighting her contribution to dismantling gender stereotypes in technical areas.


The impact of the project has been so important that work has begun on a 2nd phase of expansion of the photovoltaic installation in the area of La Fazenda, the Casa do Gaiato farm.

With this project, CoG has not only set a new standard in the use of renewable energy, but has also created a replicable model that could be the key to a sustainable energy revolution throughout the region.

Technical advice on standardizing processes for creating micro-networks in rural areas in Mozambique

Technical advice on standardizing processes for creating micro-networks in rural areas in Mozambique.

According to World Bank sources, in 2020 only 30.6% Mozambique’s population had access to electricity. The great challenge facing the country is its total electrification by 2030, especially of rural areas that are far from the grid.

FUNAE is the main public body in charge of electrifying the most remote and isolated areas, mostly with the implementation of micro-grids powered by renewable energy (solar photovoltaic and hydraulic). Currently, tools are needed to build and maintain the mini grids and guarantee quality standards.

In this context, our engineer and head of international area @MarcosMorales has given training to provide process-standardization tools for designing and implementing micro-grids that will provide electricity in rural areas.

This technical assistance is provided for FUNAE as part of a project led by our colleagues @Aiguasol, which also proposes the design of a digital tool to control and monitor micro-grid data as part of the DigutalEnergy Challenge for Utilities 2022 competition.
