Operations & Maintenance

Having worked with the leading equipment manufacturers, and with an experience of over 10 years in the O&M of solar power stations, Avenston carefully looks after our customers’ assets. We expand the useful lifetime of facilities, maximize their profitability, streamline their performance and availability, and minimize their consumption and operating costs. Our experience allows mitigating project risks by offering increased security to the owners, investors, and insurance companies facilitating management in investment projects.

Avenston pays great attention to the technical and service maintenance of renewable energy assets which can be routine, or non-routine, as well as in event of equipment failure or fault. We offer an extensive scope of services that can be customized to meet customer requirements:

  • Detailed analysis of technical conditions of the equipment
  • 24/7 monitoring and fault detection
  • 24/7 security control
  • Scheduled test and inspection visits
  • Monthly and annual operation reporting
  • Ground maintenance and land management
  • Thermographic diagnostic surveying
  • Preventive PV and LV equipment maintenance, including panel cleaning
  • HV systems and equipment maintenance
  • Warranty management and spare parts stock control
  • Trouble-shooting processes



Additional services

Avenston also performs works on the full technical inspection of any type of solar power station, performs thermal imaging examinations, and carries out repairs of supporting metal structures (both fix-tilt and trackers). Our service team can conduct extraordinary visits if it is necessary to quickly eliminate the consequences of accidents or identify critical defects in the operation of any equipment of the solar power plants. Upon the сustomer’s request, the modernization of the existing systems is possible, which provides expanding the functionality.

Service maintenance efficiently performed allows not only to identify possible shortcomings in the operation of the equipment but also provides its guaranteed operation. The benefits resulting from our service support: guaranteed high level of service, оptimization and ability to schedule servicing and repair costs, minimization of business risks by downtime reducing and prevention of possible accidents, application of advanced technologies and techniques, responsiveness.

Operations and Maintenance of Solar Power Plants

Avenston offers its customers several packages of services for the operation and maintenance of solar PV power plants.

  • The basic package includes full maintenance of all photovoltaic and other equipment on the DC side, as well as alternating current up to 1 kV (solar panels, inverters, electrical panels, cables, etc.). This service is performed during quarterly visits to the facility by the technical specialists of our company. In addition, the basic support package includes 24/7 monitoring of the operation of the photovoltaic solar station.
  • The next package will add services for operational and maintenance of equipment 1 kV and above (transformer substations and switchgears). In this package of services, our company undertakes all the work on periodic maintenance of the equipment of the solar power station, which ensures its continuous and maximum efficient operation.
  • In the third O&M service package, operational maintenance of the PV power plant and some common works at the power plant are added. In this service package at your facility will always be our attendants. Our employees will perform work on continuous monitoring of the condition of the equipment, do the necessary checks and tests, remove grass, manage the warehouse of spare parts and equipment. We recommend this package for owners of solar power plants who wish to receive full technical support for the operation of their solar power plants.
  • If you need full service and operational support, we offer you the maximum fourth package, which also adds services for the physical security of the solar power station and maintenance services for the equipment of the ASKUE system.

In addition to the service packages described above, Avenston also performs separate work on the full technical inspection of any type of solar power station, performs thermal imaging examinations, organizes the washing of the surface of solar panels, and carries out repairs of supporting metal structures (both with a fixed angle and trackers). Our service team conducts extraordinary visits if it is necessary to quickly eliminate the consequences of accidents or identify critical defects in the operation of any equipment of the solar power station.

The benefits resulting from Avenston’ service support:

  • Guaranteed high level of service;
  • Optimization and ability to schedule servicing and repair costs;
  • Minimization of business risks by downtime reducing and prevention of possible accidents;
  • Transfer of responsibility for maintenance;
  • Application of advanced technologies and techniques;
  • Responsiveness.

All the evidence points towards the fact that Operations and Maintenance are being recognized for their critical role in optimizing photovoltaic solar power assets. O&M has long evolved from the days of being an add-on to Engineering, Procurement and Construction (EPC) contracts and has charted its own course to become a standalone industry that is seen as a critical component in the solar energy value chain.

Many investors are more interested in reducing risk than maximizing internal rate of return (IRR). Investors would prefer 5% IRR with 100% certainty over 10% IRR with 50% certainty, although the two are of statistically equivalent value. Investors will make an investment decision based on mitigating performance risk with effective O&M, and then the financing rates are determined mainly through competition from other banks. Standardization of O&M practices will facilitate both investor analyses of risk factors as well as securitization of PV asset cash flows. Risk reduced by effective O&M will enable banks to qualify more projects, and that will eventually increase competition and reduce borrowing costs.

The market for services around solar PV assets is changing and becoming increasingly mature. This leads to the observation, that O&M is becoming a business and is separating from EPC, which it was attached to in the early years of the industry. The O&M business across Europe is also consolidating and specialised companies are offering their services. In these guidelines O&M focuses on the technical operations and maintenance services for utility-scale PV power plants. Asset management, which is also a very important piece of PV plant ownership, is seen to cover all the commercial and administrative activities of importance during the lifetime of the plant.
