Photovoltaic Maintenance for Businesses and Homeowners

At Fotovol we offer a complete photovoltaic maintenance service to guarantee the maximum performance of your installation throughout its useful life. We understand that our clients want the peace of mind of knowing their installation will be in good condition, which is why we design maintenance contracts adapted to both private homes and businesses and industrial installations.

Our service includes constant performance monitoring, periodic preventive visits, module cleaning, inverter and fan inspection, DC string verification and battery and structure condition checks. In addition to guaranteeing performance, all of this serves to detect potential damage in time and report it to the manufacturer so it is covered under the product warranty.

If you have solar panels at home, an annual maintenance contract guarantees that your installation produces at maximum capacity throughout its useful life and that any incident is covered by the manufacturer’s warranty. At Fotovol we handle everything so you don’t have to worry about a thing.

Monitoring and incident alerts: Continuous performance monitoring of your installation with immediate notification in case of production drop or detected fault.
Annual inverter inspection: Verification of the correct operation of the inverter and its fans, the most critical component of the installation.
DC string verification: Checking the condition of strings to detect underperforming modules or deteriorated connections.
Photovoltaic module cleaning: Periodic cleaning of panels to remove dirt, dust and deposits that reduce production.
Roof and structure inspection: Checking the condition of the roof and panel support structures to detect potential structural damage.
Battery condition check: If you have a solar battery, we check its charge status, cycles and performance.
Energy supplier support: We assist you with any procedures with your electricity supplier related to self-consumption and surplus energy.

From 10 years of installation life, we recommend adding a panel-by-panel thermographic study to detect modules with advanced degradation and replace them before they affect overall performance.

Maintaining an industrial photovoltaic installation is not the same as maintaining a residential one. Production volumes, thermal loads and legal requirements demand a specific service with higher visit frequency, detailed performance reports and technical response capability for incidents affecting production.

At Fotovol we offer operation and maintenance (O&M) contracts for businesses, industrial warehouses and ground-mount photovoltaic plants, adapted to the installed power and consumption profile of each client.

SCADA monitoring and incident alerts: Continuous production monitoring with real-time alerts for any deviation from expected performance.
Periodic preventive visits: Complete installation inspection with higher frequency than in residential environments, adapted to the criticality of the system.
Inverter and protection inspection: Verification of correct operation of inverters, electrical panels and protection systems in compliance with current regulations.
Professional module cleaning: Periodic cleaning with professional equipment to maintain production at optimal levels in large-surface installations.
Thermographic studies: Detection of degraded modules, hot spots or connection faults using panel-by-panel infrared thermography.
Revamping services: Updating and modernising key components to extend the plant's useful life and improve its performance.
Performance reports: Periodic delivery of detailed reports on real vs. expected production for tracking installation profitability.

Continuous monitoring is the foundation of any serious photovoltaic maintenance contract. We don't wait for the client to detect a problem — we detect it first. A system producing 15% less than expected can go unnoticed for months without active monitoring, generating real financial losses that a good monitoring system prevents.

- Real-time tracking: Permanent access to your installation's production data — energy generated, consumption, surplus fed to the grid and battery status if you have one.
- Automatic alerts: The system automatically detects any significant deviation from expected performance and notifies us immediately so we can act before the incident affects production.
- Periodic reports: You receive regular reports on your installation's real performance, compared to expected production according to the weather conditions of the period.
- Warranty management: When we detect a fault covered by the manufacturer's warranty, we handle the communication and processing directly — without you having to manage anything.

Frequently asked questions about photovoltaic maintenance

Can I take out a maintenance contract even if you didn't install my panels?

Yes. At Fotovol we offer a maintenance service for any photovoltaic installation, regardless of who installed it. Before starting the contract we carry out an initial inspection of the installation's condition to assess its real situation and detect any pre-existing issues. From there, we take charge of the maintenance as if it were our own installation.

What happens if my installation breaks down between visits?

The continuous monitoring included in all our plans detects any performance drop or fault in real time, before it becomes a major breakdown. If an incident is detected, we notify you immediately and assess the necessary action. Premium plan clients also have 2 annual technical visits included to resolve incidents on-site at no additional cost.

When will I start to notice the benefit of maintenance?

From day one. Continuous monitoring ensures your installation always produces at its maximum expected performance — any deviation is detected and corrected before it generates accumulated losses. In the long term, proper maintenance extends equipment life, avoids premature replacements and ensures manufacturer warranties are correctly activated when needed. The cost of the contract is more than recovered through additional production and avoided repairs.
