Operation and Maintenance

Cleaning and Clearing

At Alterna Energía, we are experts in photovoltaic cleaning and clearing, acting at the optimal time to maximize production and maintain the installation in optimal conditions, ensuring efficiency, safety, and asset care. Cleaning and clearing optimize production, extend the installation’s lifespan, and maximize your investment’s return.

We plan each intervention according to local weather conditions, dirt monitoring, vegetation growth, and installation needs, combining manual, mechanized, and robotic techniques without interrupting operation.

The accumulation of dirt and shadows can reduce production by 5% to 20%. Cleaning at the right time allows you to recover lost production and maximize return on investment.

Frequently Asked Questions

Why are cleaning and clearing important in a photovoltaic plant?

Photovoltaic cleaning and clearing are essential to maintain installation performance. The accumulation of dust, dirt, or shadows caused by vegetation can reduce energy production by 5% to 20%. Proper maintenance allows you to recover that production and maximize return on investment.

The frequency depends on factors such as local weather conditions, environmental dirt levels, the presence of dust or pollen, and vegetation growth. That’s why it’s crucial to conduct technical monitoring that allows planning interventions at the optimal time, without affecting plant operation.

Manual, mechanized, and robotic techniques are combined according to the installation’s characteristics. The goal is to ensure effective and safe cleaning, protecting modules and electrical components, and ensuring that the intervention does not interrupt energy production.

Planned maintenance improves energy efficiency, extends equipment lifespan, reduces operational risks, and protects asset value. A clean plant not only produces more energy but also maintains its profitability and stability in the long term.
