Photovoltaic parks: what are they, types and advantages for a greener future?

Photovoltaic parks are large installations that convert sunlight into electricity. They consist of interconnected solar panels that absorb the sun’s energy and send it to the grid. These solar parks generate clean energy to supply industries, communities and residential areas. They also have the possibility to sell the excess energy produced. There are different types and advantages, as well as some challenges associated with their initial investment and dependence on sunlight. In addition, the largest photovoltaic parks in India, China and Spain stand out.


Photovoltaic systems: What are they and how do they work?

Photovoltaic installations are systems designed to convert sunlight into electricity. These installations are part of photovoltaic parks, which are made up of various interrelated elements. The main components are described below:

Solar panels: The basis for photovoltaic parks

Solar panels, also known as photovoltaic modules, are responsible for capturing solar energy and converting it into direct current. They are formed by joining photovoltaic cells containing semiconductor materials, such as silicon. When photons of sunlight strike the cells, they generate an electric current that is harnessed as renewable energy.

Mounting Structures and Solar Trackers: Maximising Sunlight Harvesting

The mounting structures support and correctly position the solar panels, allowing them to be optimally oriented towards the sun. In addition, solar trackers are mechanical devices that follow the path of the sun throughout the day, optimising the collection of sunlight and maximising the efficiency of photovoltaic panels.

Additional components: Transformer stations, inverters and safety equipment

Transformer substations are essential equipment in photovoltaic parks, as they convert the direct current generated by the solar panels into alternating current, suitable for distribution to the electricity grid. Inverters, on the other hand, are responsible for transforming direct current into alternating current and keeping it stable. In addition, the solar parks are equipped with safety equipment, such as fire protection systems and surveillance systems, to ensure the correct operation and safety of the installation.

Civil works: Importance of adequate infrastructure

The civil works include the construction of the bases and foundations where the solar panels will be installed, as well as the infrastructure necessary for the correct operation of the photovoltaic solar parks. This includes the installation of drainage systems, cable ducting and site preparation. Adequate civil works are essential to guarantee the stability and durability of the installation over time.


Types of photovoltaic parks

Large-scale solar parks: Supplying the grid

These are photovoltaic installations that occupy large areas of land and are responsible for generating solar energy to supply the electricity grid. These parks are composed of a large number of interconnected solar panels, which absorb solar energy and convert it into electricity. The energy generated is sent directly to the grid, where it can be distributed and used by industries, communities, residential areas and other sectors requiring large-scale electricity supply. The main characteristic of large-scale solar parks is their ability to generate large amounts of energy, which makes them important sources of electricity supply. They are especially useful in regions with high energy demand or in areas where land availability is ample. They also contribute to the reduction of greenhouse gas emissions by using a clean and renewable energy source.


Community solar parks: Renewable energy for communities and businesses

These are smaller-scale installations intended to supply renewable energy to neighbourhood communities, businesses or other consumer groups. These parks allow several participants to benefit from solar power generation and share the associated costs and benefits. In community solar parks, the energy generated is distributed among the participants according to their consumption or participation in the project. This gives them access to clean, renewable energy without the need to invest in individual installations. They also promote environmental awareness and community participation in the transition to more sustainable energy sources. Community solar parks are an attractive option for those who wish to benefit from solar energy but do not have the possibility or capacity to install solar panels on their own properties. They are also an alternative for those who wish to reduce their dependence on fossil fuels and contribute to environmental protection.


Advantages and disadvantages of photovoltaic parks


  • Clean and renewable energy generation: they use the sun’s energy as their main source, which reduces dependence on fossil fuels and contributes to the reduction of greenhouse gas emissions.
  • Energy available around the clock: Solar panels can generate electricity even on cloudy days, ensuring a constant supply of renewable energy.
  • Long-term cost savings: Generating electricity from sunlight can significantly reduce long-term energy costs by tapping into a free and abundant source.
  • Ease of installation in various environments: they can be adapted to different locations and sizes, making them suitable for installation in both rural and urban areas.
  • Environmental benefits: In addition to reducing emissions, they help to conserve natural resources by not using water or producing pollutants during operation.


  • High initial investment: requires significant financial investment, which can be an obstacle for some projects due to high upfront costs.
  • Dependence on solar intensity: The amount of energy generated by PV parks is directly related to the intensity of sunlight, which means that at certain times or in adverse weather conditions, production may decrease.
  • Visual impact on the environment: they occupy large areas, which may cause aesthetic concerns and visual impact on the surrounding environment.
  • Storage issues: Although solar parks generate energy during the day, efficient storage systems are needed to ensure continuous availability of energy during the night or at times of lower solar irradiation.
  • Possible need for grid adaptation: may require adjustments to the existing grid infrastructure to ensure proper integration and distribution of the generated energy.


Environmental impact of photovoltaic parks

The installation of photovoltaic parks has a highly beneficial impact on the environment. By converting solar energy into electricity, these parks generate a clean, renewable source of energy with no greenhouse gas emissions or air pollutants. This contributes significantly to reducing the carbon footprint and slowing climate change.

They are also considered a sustainable and environmentally friendly solution. By harnessing sunlight as a source of energy, it avoids the exploitation of non-renewable resources and reduces dependence on fossil fuels, such as oil or coal, which are highly polluting and contribute to the depletion of natural resources.

Another important benefit is its ability to generate electricity continuously throughout the day. Although the amount of energy produced depends on the intensity of sunlight, solar panels continue to generate electricity even on cloudy days or during hours of reduced solar radiation. This ensures a constant supply of renewable energy, reducing dependence on other more costly and polluting energy sources.

Photovoltaic parks also contribute to job creation in the renewable energy sector, generating jobs both in installation and maintenance as well as in the manufacturing industry of solar panels and associated equipment. This boosts local and regional economic development, promoting job creation and investment in sustainable infrastructure.

Benefits of photovoltaic parks:

  • Clean and renewable energy generation.
  • Reduction of greenhouse gas emissions and air pollutants.
  • Contribution to the fight against climate change.
  • Savings in fossil fuels and non-renewable resources.
  • Constant energy supply throughout the day.
  • Reducing dependence on polluting energy sources.
  • Job creation in the renewable energy sector.

Installation of photovoltaic parks: New projects and alternatives for individuals and companies

It has become an increasingly popular option for individuals and businesses wishing to take advantage of the benefits of solar energy. In addition to contributing to clean and sustainable energy generation, these projects offer the opportunity to reduce electricity costs and reduce dependence on fossil fuels.

For those wishing to embark on a new PV project, it is important to have expert advice in the field. Companies specialising in solar panels can provide a customised study and support at all stages of the process, from the initial assessment to the implementation and commissioning of the solar park.

  • The initial assessment includes a detailed analysis of the site where the PV park will be installed. A feasibility study is carried out taking into account factors such as solar radiation, topography of the land and legal or regulatory restrictions.
  • Once the results of the evaluation have been obtained, the design and sizing of the PV park is carried out. At this stage, the number and arrangement of the solar panels and the configuration of the energy storage system are determined, anticipating possible peaks in demand and guaranteeing a continuous supply.
  • Once the design has been defined, the installation and assembly of the solar panels and other system components begins. Adequate civil works are essential to ensure structural strength and proper attachment of equipment, both in the case of large-scale solar parks and in the case of community or residential installations.
