Solar energy is growing in Portugal, but installations done without criteria can bring dangers – from fire to loss of performance. 
See how to avoid problems and protect your investment.

1. Main Failures

• Undersized cables: heat up and wear out insulation.
• Loose or oxidized connections: generate hot spots and sparks.
• Absence of SPD: exposes the system to voltage spikes and atmospheric discharges.

2. Why does this matter?

• Fires: local electrical failures can evolve into flames.
• Accelerated wear: components exposed to excessive heat or humidity lose efficiency and lifespan.
• Unexpected costs: emergency maintenance and possible insurance coverage refusal.

3. Essential Best Practices

• Detailed project – Load survey and shading analysis.
• Certified materials – Cables, connectors and SPD with CE/TÜV seal.
• Tests before energization – Electrical continuity and thermography to identify "hot spots".
• Periodic maintenance – Semi-annual review of connections and careful cleaning of modules.

How Geoclima Guarantees Safety

• Pre-installation audit: we map risks and needs.
• Certified team: installers trained in NR-10 standards and photovoltaic best practices.
• Continuous monitoring: early detection of anomalies for immediate action.

Protect your solar system: investing in quality and technical control avoids risks, increases production and improves return.
