Evaluation of Solar Plants
Installation of photovoltaic systems (PV systems) on roofs, near motorways or at disused land is becoming more and more popular. In 2012 approximately 185,000 solar power units with a total capacity of 7.6 GW were installed in Germany according to information provided by the German Solar Industry Association (BSW-Solar/www.solarwirtschaft.de).
The number of new installations will increase at the same rate as the reduction in purchase costs over the next few years.
PV System Quality
Generally for the investor it is not easy to evaluate the quality of PV systems. Even though it is mostly a requirement that all the components used are tested or certified. Good results cannot be expected unless its interplay and professional installation can be guaranteed. Certainly the systems' service life of between 25 and 30 years can only be achieved if good components are used and the design and installation is carried out in accordance with state-of-the-art technology.
The blueTÜV Solar Pass issued by TÜV Thüringen is used to guarantee a high quality standard for PV systems. The pass contains a list of all mechanical and electrical components used together with its certification, the relevant data sheets are compiled and the installation is assessed. The blueTÜV Solar Pass includes a detailed test report which shows all the structural and electrical parameters.
The TÜV Thüringen blueTÜV Solar Pass enables the investor to obtain complete documentation for his PV systems. Investors, financers and insurers are given a maximum security that the PV systems
- has been correctly installed and put into operation by a specialised company in accordance with state-of-the-art technology,
- only uses high-quality and certified PV modules and components, and that
- all guidelines and standards have been observed.
The blueTÜV Solar Pass can be used as proof of quality to enable banks to offer credit more simply. Some insurance companies even offer lower premiums if a Solar Pass can be presented.
