Operations & Maintenance of Solar PV systems and BESS
Why Operations and Maintenance matter?
Protect your investment. Maximize your energy yield. Reduce long‑term costs.
We keep your Solar PV and Battery Energy Storage Systems operating at peak performance — every day.
We manage all day‑to‑day operational tasks to ensure your system runs efficiently and reliably. This includes performance optimization, physical inspections, and both digital and cybersecurity measures. Our goal is simple: higher availability, lower OPEX, and stable long‑term production.
Why Maintenance matters
Environmental exposure such as wind, rain, moisture, heat, snow, and ice creates wear and tear. Mechanical and electrical components can fail, connectors loosen, and design or installation flaws can reveal themselves over time.
With their many interconnected components, PV and BESS systems have numerous potential points of performance loss or failure.
Our Maintenance Goals
Our priority is to maximize kWh yield and secure the return on your investment.
Maintenance costs are only a small fraction of your total CAPEX, yet they play a crucial role in ensuring optimal system performance and long-term stability.
With customized maintenance packages, remote monitoring, and our local presence in Hungary and Slovakia, we quickly identify and address issues — before they affect your production.
Routine Maintenance
Regular maintenance is essential for maintaining high energy output, early fault detection, and preserving long-term asset value.
Our experienced engineers design tailored maintenance packages that extend system life and protect your investment.
Every hour of uptime matters. That’s why we offer fast response times wherever you operate in Hungary and Slovakia — on the ground or on the roof.
Ground or rooftop – we combine physical expertise with digital intelligence
Our Maintenance Services include
- Planned, predictive, and preventative maintenance tailored to your system’s needs.
- Periodic and ad hoc on‑site inspections.
- Inverter maintenance and retrofits in line with manufacturer instructions, including cooling‑fan cleaning and Resistance Isolation (RISO) ground‑fault checks.
- Quality panel cleaning using soft water by trained personnel.
- Green‑space maintenance, grass cutting, environmental control, and full site cleaning.
- Testing mechanical components for stress and correct tension.
- Low‑ and high‑voltage electrical equipment testing.
- Stock and spare‑part management.
- Compliance with all relevant safety and performance standards.
- Maintenance of fire‑suppression systems for thermal‑runaway protection.
- Mitigation of rodent damage and environmental exposure to prevent costly repairs.
- Corrective activities, including identifying faults, repairs, documentation, warranty handling, diagnostics, and servicing.
Scheduled and unscheduled tasks to keep your solar PV and battery system in optimal condition, including cleaning, tightening of connections, and replacement of worn parts.
Fault finding and service
- Diagnostics and fault identification.
- Root‑cause analysis and mapping of potential causes.
- Aerial thermal inspections of panels, connectors, and inverters.
- Spare‑part replacement and repairs.
We use a methodical approach to diagnose and resolve PV system issues, including inverter clipping or optimizer faults. Fault finding involves testing, troubleshooting, and implementing solutions to restore normal operation quickly. This includes identifying and diagnosing any issues or malfunctions within the solar PV system, followed by systematic testing and troubleshooting to determine the root cause of the problem and applying corrective measures to restore full performance.
Advanced monitoring
- Continuous real‑time performance tracking and data analysis covering yield, charge/discharge cycles, temperature trends, and voltage levels to ensure stable operation.
- Production report preparation and timely reporting for full transparency and performance oversight.
- Cybersecurity and cyber resilience measures to protect system integrity and digital assets.
Advanced inspections
- Aerial or handheld thermal inspections performed by our drone‑certified engineers.
- AI‑assisted and human analysis of electrical cabinets, cables, connections, and PV modules.
- Identification of issues such as micro‑cracks, snail trails, hotspots, hail impacts, and diode failures.
- Electrical safety and lightning‑protection inspections, including RISO testing.
- IV‑curve tracing with measurements up to 1500 V.
- Customized inspection packages for customer acquisitions or asset sales.
- Scheduled or ad hoc inspections tailored to site conditions.
