Installation of photovoltaic plants

Solarea Tech specialises in undertaking large-scale photovoltaic installations for businesses, providing sustainable and efficient solutions. These installations include:

• Ground-mounted photovoltaic plants: Large-scale projects in areas dedicated exclusively to solar energy production.
• Industrial buildings: Installation of solar panels on the roofs of factories and warehouses.
• Parking roofs: Implementation of solar systems on parking roofs.
• Community rooftops: Collective self-consumption solutions on residential rooftops.
• Agricultural or livestock land: Integration of solar energy in agricultural and livestock production areas.

To determine the ideal location for a PV park, Solarea Tech follows a meticulous process that includes several key steps:

• Site assessment: The first step is to conduct a thorough analysis of the topography of the site. It is crucial to ensure that the selected area has an optimal slope and orientation for the installation of the solar panels.
• Solar radiation study: It is essential to measure the amount of solar radiation the site receives throughout the year. We use specialised tools and software to perform this analysis, which allows us to forecast the expected energy production.
• Access to infrastructure: We assess the proximity of the site to existing electricity grids, as it is essential to facilitate the connection and distribution of the energy generated.
• Environmental and legal impact: We carry out environmental impact studies to ensure that the installation of the photovoltaic park does not cause significant damage to the environment. In addition, we review local regulations and manage the obtaining of all necessary permits.
• Economic factors: We analyse the costs associated with the land, installations and connection to the electricity grid. We also evaluate possible subsidies and grants available that can reduce the total cost of the project.

For a solar farm to be profitable, generally between 1.5 and 2 hectares of land is needed for each megawatt (MW) of generating capacity.

This space includes the area for the solar panels, maintenance corridors and support infrastructure. The efficiency of the panels, the configuration of the system and the characteristics of the terrain also influence the size required.

The amount of energy produced by a PV plant depends on several factors. Some general estimates are given below:

• A 1 megawatt (MW) photovoltaic plant can produce between 1,200 and 1,500 megawatt hours (MWh) of electricity per year, depending on the solar irradiation of the location.
• In regions with high solar irradiation, such as Alicante, a PV plant can generate more energy. For example, in southern Spain, production can reach 1,500 MWh per MW installed per year.
• In regions with lower solar irradiation, production can be lower, around 1,200 MWh per MW installed per year.
• More efficient solar panels can convert more sunlight into electricity, increasing the plant’s energy output.
• Factors such as the number of sunny days, temperature and the cleanliness of the panels affect energy production. Areas with less clouds and dust tend to have higher energy generation.

The investment for a photovoltaic park can vary depending on a number of factors..

• Cost of investment in the purchase of solar panels and inverters.

• Construction costs including site preparation, installation of mounting structures, cabling and grid connection. The topography of the site and accessibility may affect these costs.

• Connection to the electricity grid can involve significant costs, especially if additional infrastructure such as transmission lines or substations are required.

• Permitting and licensing can vary in cost depending on local regulations and the complexity of the project.

• Proper maintenance ensures the optimal performance of the PV park. Although these costs are recurring and are not part of the initial investment, it is important to consider them in the financial analysis of the project.

This maintenance is crucial to ensure optimal performance and longevity of the system, including tasks such as periodic inspections, cleaning of the solar panels, and checks of all components. Among the most influential factors we highlight:

• The location of the PV plant plays a significant role in the cost of maintenance. In areas with a lot of dust, pollen or sand, the frequency of cleaning the solar panels must be higher to maintain the efficiency of the system. In addition, extreme weather conditions, such as high temperatures, strong winds or heavy rain, can affect the durability of components and increase the need for corrective maintenance.
• The size of the PV plant also influences maintenance costs. Economies of scale can reduce the maintenance cost per megawatt in larger plants, as some maintenance tasks can be performed more efficiently and with lower unit costs in larger installations.
• The type of maintenance contract in place also affects the overall cost. Long-term maintenance contracts may offer better rates and conditions, providing a balance between preventive and corrective maintenance.

The installation of a solar photovoltaic plant requires compliance with various standards and regulations to ensure the safety, efficiency and sustainability of the project. The key aspects of the regulations for installing a solar PV plant are described below:

• Before starting the construction of a photovoltaic solar power plant, it is necessary to obtain a building permit from the competent local authority. This permit ensures that the project complies with planning and land use regulations.
• Depending on the size and location of the project, an Environmental Impact Assessment may be required. This study evaluates the potential effects of the project on the environment and proposes mitigation measures to minimize negative impacts.
• In order to inject the generated energy into the power grid, it is necessary to obtain access and connection permits from the distribution company.
• The installation must comply with the electrical safety standards established by current regulations. This includes the correct installation of equipment, protection against overloads and short circuits, and the implementation of protection systems for workers and the public.

At Solarea Tech, we take care of managing all permits and comply with current regulations, ensuring a safe, efficient and legally compliant installation.
