Service and Maintenance

A photovoltaic power plant may be due to improper installation or neglected maintenance not a good servant but a bad master! This is an electrical installation; PV panels can achieve up to several hundred volts of DC voltage. As any electrical device also our photovoltaics are subject to the obligation in accordance with CSN331500 to carry out the regular inspections of electrical installations. After the expiry of a certain period, which is for the vast majority of installations four years, the operator is obliged to prepare a periodic report of revision of electrical installations.

Our engineers regularly encounter unprofessionally made PV installations and it is only a matter of time when some failure or injury happens. In addition to high-priority safety issues of your house, company, cottage or production hall there is also an economic point of view which needs to be considered. In the event of a fire the insurance company requires a document of a valid inspection of electrical installation. Otherwise it is very difficult to claim damages from the insurance company.

Have your PV installation checked by our experts!

Small PV plants 0 – 30kWp

The vast majority of photovoltaic power plants (91.5%) have low power, i.e. up to 30kW. Small power plants are usually installed on the roofs of houses; however not all installations were always carried out professionally and the operator did not have to be advised of the required maintenance. Sometimes the operator even does not know about the obligation to perform the regular inspection of electrical installation.

Medium and large PV plants

Photovoltaic power plants of higher power always require an individual approach. We provide a regular service of PV power plants of several tens of MW and therefore we enable many operators to have regular and high yields. Nearly a third of serviced premises is equipped with tracking systems (i.e. trackers).

WE PROVIDE A 24 HOUR SERVICE, 365 DAYS A YEAR

We provide a wide range of services in the field of photovoltaics:

• Regular service of PV
• ​Audit reports of law voltage, high voltage, dispatching management
• Thermal imaging inspection of PV panels, control panels, inverters
• Mowing the grass on the premises of PV power plants
• Inverters maintenance of all brands
• Regular greasing of moving parts of tracking systems
• Remote monitoring, camera surveillance
• Guaranteed emergency service 24 hours a day, 7 days a week, 365 days a year

Please contact our experts who can offer you our services. We will look after your PV power plant with the same care as it were our own plant.

Why is the PV service important?

• Regular inspection of components can prevent the release of the panel and subsequent damage not only to photovoltaics but also to other properties and personal health.
• ​Checking of cable lines can prevent mechanical damage to cables and disruptions in PV production. For example snow slide can cause great damage not only on a construction but also on poorly attached and unprotected cables.
• Checking of fuses, breakers and all clamps prevents the contact resistance and associated heat generation which can cause fire.
• Software control and update for inverters can significantly optimize the operation of your PV. Proper inverter settings can reduce the time required to restart the inverter from several minutes to just a few seconds.
• Regular filters cleaning of the inverter helps to reduce the energy consumption to run the ventilators and the dust removal also minimizes the risk of fire.
• Malfunction of the PV panel can be detected visually (e.g. cracked glass can put the PV panel out of production due to water leakage during a few weeks) and also via thermal imaging tests. Thermovision can reveal possible defects of panel cells. In the vast majority PV panels are connected into sections in series and one defective cell of the panel can set out of order the entire section.
• Shading of even a small part of the single PV panel can also set out of order the entire section. Minimizing shading of panels leads to a higher production.
• Optimizing the operation of your PV power plant can significantly improve the economic efficiency. Maximum utilization of produced electricity for your own consumption reduces your energy costs. Our experts will suggest you specific optimization options.
