The next stage is the inspection of the facility.
The tightening is checked immediately to check if they keep the panels anchored or if they have not loosened by checking with a wrench if the tightening torque is within the range established by the user manual of the photovoltaic panels that have been mounted.
It is then necessary to ensure that the ballasts have not moved due to climatic stresses (wind) or thermal expansion of the materials.
Our structures are supplied together with the sheaths on which they rest during installation, in order to preserve the coverage and avoid slipping thanks to the grip that the sheath in recycled rubber produces.
In addition, replacing them is very easy and the system can also be expanded by adding new rows of ballasts without having to redesign the layout of the system itself after evaluating the electrical part.
Last step, the test on the electrical part
The maintenance is completed by checking the inverter, tightening AC / DC panel terminals, string voltages, production data, connectors, etc., also checking the correct arrangement of the cables. Also, in this, Sun Ballast can help thanks to Cablowind, the new concrete duct that has the dual function of additional ballast and correct accommodation of the cables.
How often should you do maintenance?
The best solution would be to do it once a year, but the assessment must be made from area to area, because, for example, there may be sand in marine areas.
In cities and industrial areas pollution has a great impact, in windy areas it is better to check more frequently. Control is obviously necessary following exceptional events (hail, storms, etc.). Another check must be made when you realize that the system produces less than usual standards. In this case it is necessary to immediately ascertain the cause (breakages, faults in the electrical systems).
