Our services

What we do

We offer engineering and consulting services specialising in photovoltaic installation projects, working with both public administrations and private companies. Project development may include:

  • Feasibility and energy yield studies.
  • Consumption analysis and system sizing.
  • PV module layout design.
  • Specification of mounting structures.
  • Sizing of inverters and main equipment.
  • Design of DC and AC electrical networks.
  • Specification of protections and safety systems.
  • Integration with existing switchboards.
  • Low or medium voltage grid connection.
  • Integration with transformer substations where needed.
  • Single-line diagrams and drawings.
  • Technical report and supporting calculations.
  • Bill of quantities and budget.
  • Technical specifications and tender documents.

Our goal is to design and deliver turnkey projects that meet each client's needs.

Study and feasibility analysis

We study consumption profiles, required power, available surface area and installation options to determine the most suitable solution. The analysis defines:

  • The optimal system capacity.
  • The number and layout of PV modules.
  • The estimated energy yield.
  • The self-consumption ratio.
  • Any potential surplus energy.
  • The electrical connection configuration.
  • Any work needed on the existing infrastructure.

Based on this assessment, we propose a technical solution that makes the most of the available solar potential and integrates into the existing energy system.

Solar self-consumption

Self-consumption allows electricity to be generated where it is used, reducing dependence on grid power.

We analyse the relationship between solar production and the installation's actual consumption and define a configuration that makes the best use of the energy generated and delivers savings for the consumer.

Types of installation

Rooftop or ground-mounted

Rooftop installations

The roofs of industrial, commercial, office or residential buildings make it possible to add renewable generation without taking up new land.

We analyse the building, available surface, orientation, shading and integration with existing infrastructure.

We define the module layout, mounting structures, inverters, cable routes and connection to the existing electrical installation, to deliver an integrated, safe system that maximises energy yield throughout its service life.

Ground-mounted installations

Ground-mounted PV installations allow larger-capacity projects, both for self-consumption and for generation.

They require an overall analysis of the site and infrastructure: layout of the PV arrays, mounting structures, internal networks, transformer substations and grid connection.

We take part in defining the complete solution, coordinating the project's technical disciplines and producing the documentation needed for construction and permitting.

Methodology

Our phased engineering service model

Our way of working is structured in phases that allow us to offer a comprehensive service, from the initial analysis to project follow-up after completion, ensuring technical, administrative and financial control throughout the process.

  1. Assessment and feasibility analysis

    Kick-off meetings, collection of consumption data, analysis of consumption and service parameters and of the electrical grid, preliminary economic study, risk identification and feasibility report.

  2. Solution design

    Sizing and calculation of the installations, equipment specification, single-line diagrams, preliminary design and preliminary budget.

  3. Funding, grant management and justification

    Where grants are available: preparation of reports and budgets, administrative procedures and responses to requests for information.

  4. Detailed design

    Technical report, electrical and structural calculations, bill of quantities, specifications, budget, construction drawings and BIM/CAD coordination.

  5. Permits and legalisation

    Building permit, administrative authorisation, grid connection, industry and environmental authorities, fire service if applicable, and certifications.

  6. Tendering and contracting

    Tender documents, award criteria, responses to queries, bid evaluation, technical reports and support for contract award.

  7. Site supervision and monitoring

    Site meetings, visits, progress certifications, quality control, cost control, variations, minutes and coordination with the contractor.

  8. Commissioning

    Test protocols, commissioning, regulatory inspections, final documentation and support for final connection and legalisation.

  9. Financial close-out and final handover

    As-built report, invoice collection, certifications, indicators, final report and responses to requests for information.
