CIE Certifications

Legalizing Your Power: The CIE 'Boletín Eléctrico'

In Spain, the **Certificado de Instalación Eléctrica** (CIE)—commonly known as the 'Boletín'—is the most important document for your home's electrical system. It is the legal proof that your installation is safe, up to code, and compliant with the 'Reglamento Electrotécnico para Baja Tensión' (REBT). At Competa Solar, as authorized electrical installers (Instaladores Autorizados), we provide the engineering expertise and official certification required for every major electrical event in your Axarquía property.

Whether you are installing solar panels, increasing your contracted power, or bringing an older property up to modern safety standards, a CIE is not just a 'form'—it is a legal requirement that protects your property value, your insurance coverage, and most importantly, your family's safety.

1. Solar Legalization: The PUES Process

A solar installation in Andalucía is only as good as its legalization. To receive 'Compensación de Excedentes' (payment for your surplus energy) from companies like Endesa, your system must be registered via the 'PUES' portal of the Junta de Andalucía. This process requires a specialized CIE that accurately describes your solar array, its inverter, and its safety protections.

We handle the entire PUES filing for you. Our engineers generate the technical memory (Memoria Técnica de Diseño), conduct the required tests (including earth resistance and insulation levels), and issue the certification. Once registered, your system is officially recognized by the 'Registro Autonómico de Instalaciones Eléctricas,' and your utility company is legally required to start crediting you for the energy you send back to the grid.

2. Power Increases (Aumento de Potencia)

Many older villas in the Axarquía are limited to a very low power supply (e.g., 3.3kW or 5.5kW). As we add modern luxuries like EV chargers, AC units, and pool heat pumps, this 'Potencia' often becomes insufficient. To increase your power limit with your retailer, you are mandatory required to provide an up-to-date CIE if your current one is more than 20 years old.

We conduct a 'Power Audit' to determine exactly how much capacity you need. If your existing electrical panel (Cuadro Eléctrico) is outdated, we upgrade it to current standards before issuing the new CIE. This ensures that your home can handle its modern electrical load safely, preventing overheating and fire risks while satisfying the strict requirements of the distribution company (e-distribución).

3. OCA Inspections for Larger Systems

For commercial properties or large residential estates with installations exceeding 25kW, the law requires an additional layer of verification: the **Organismo de Control Autorizado** (OCA) inspection. This is a third-party audit conducted by an independent body (like TUV or SGS) to verify our work.

Competa Solar has a 100% pass rate for OCA inspections. We manage the coordination with the inspectors, prepare the site for the audit, and ensure that every technical detail—from cable sizing to 'Sobre tensiones' (surge protection)—is flawless. Our deep understanding of the andalusian technical criteria ensures a smooth, stress-free certification process for even the most complex high-power installations.

4. Why Choose an Authorized Installer?

In the Axarquía, many 'handymen' offer electrical work, but only an Authorized Installer registered with the Ministry of Industry can legally sign a CIE. At Competa Solar, we take this responsibility seriously. We are based in Cómpeta and held to the highest professional standards. By choosing us, you are guaranteed that your electrical certification is backed by professional indemnity insurance and recognized by every utility company and notary in Spain.
