Operations & Maintenance for PV power plants

The provision of Operations and Maintenance (O&M) services has been emerging as an important field for the photovoltaic (PV) sector. Over the last couple of years there have been major developments in this part of the value chain and there is no doubt that demand for O&M services worldwide will only increase. The universal recognition of the positive factual impact that professional O&M has on the technical and economic lifetime performance of solar PV system, especially in a period with many changes in the regulatory and support scheme environment, supports that forecast.

Avenston pay a great attention to the development of technical and service maintenance of power supply and power generating systems. Service maintenance can be routine, non-routine, as well as upon some event (equipment failure or fault). The implementation of service support by our specialists is possible for any equipment. The availability of special equipment, spare parts, and highly skilled staff can prevent or solve problems of any complexity at the highest priority as soon as possible.

Our company performs the following O&M services:

  • Detailed analysis of the technical condition of equipment;
  • Software support after commissioning work implementation;
  • Execution of works by the electrical laboratory;
  • Execution of the full range of scheduled maintenance;
  • Trouble-shooting processes;
  • Preventive maintenance;
  • Consultation.

Upon сustomer’s request, the modernization of the existing systems is possible, which provides expanding their functionality of the installed systems. Service maintenance efficiently performed allows not only to identify possible shortcomings in the operation of the equipment, but also provide its guaranteed operation.

The benefits resulting from our 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.

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.
