Even the modules themselves are built to last. The manufacturers usually offer a 25-year performance guarantee; in most cases the modules generate power for more than 30 years.
But there may be parts, that impair the overall performance of a system temporarily. With a maintenance contract with SYBAC Solar problems are spotted at an early stage and removed fast, securing your investment. Based on our experience as planners and developers, our maintenance measures are highly effective, securing the long-term productivity and operational reliability of your system.
Our maintenance contracts secure your investment and make it easier to plan future revenues – in many different ways:
SYBAC Solar not only offers the maintenance service for systems of its own design. We also offer advice to owners and operators of already established plants on how to optimise their maintenance contracts and systems.
In the central control rooms at SYBAC Solar, relevant operating data of the monitored plants is gathered and controlled. If anything irregular is detected, the origin of the problem can be analysed and pinpointed within seconds. This systematic problem location process lets us react not only more directly, but much faster than with any other solution.
A defined number of reference modules are tested under laboratory conditions prior to construction and during operation of our systems as part of our quality assurance system and in order to guarantee quality. Damaged modules that could result in a loss of performance can thus be detected at an early stage and replaced under manufacturer's warranty.
A precisely defined level of radiation is generated in the solar simulator, corresponding to the sun's radiation in high-summer in a cloudless sky. Under laboratory conditions, the outputs of individual PV modules can therefore be reproduced and compared with each other at continuous radiation values . Different characteristic curves can then be visualised using a complex programme and compared with the respective manufacturers' specifications.
The photovoltaic effect is converted using what is know as the electroluminescence process, in which radiation is directed to the PV module that then produces photons. Any damage can then be visualised using a special lens working in the UV waveband. These images are then analysed on a high-resolution screen so that even the very smallest micro-cracks in the silicon cells become visible, which can be the cause of a loss of performance.
