Photovoltaic Systems

Over a few years photovoltaic systems have strongly developed in Italy and all over the world, being it a reliable and economically convenient technology, an efficient solution for families and companies, which made it possible to reduce the electricity bill and produce clean energy.
Currently, even if there is no feed-in tariff, the installation of a photovoltaic system is still a great, economically convenient opportunity to reduce the electricity bill due to a remarkable reduction in the module price, performance improvement and the possibility to deduct 50% of investment expenses,
Having executed more than 100 installations, today our company is more and more determined to propagate this technology. The execution of numerous installations let us gain a lot of experience and create a team of highly qualified designers and installers who can carry out customized solutions for our clients.  
We design and carry out a wide range of solutions: partly integrated and integrated installations, installations on platform roofs and roofings, ground-based installations, sun-following installations, photovoltaic lamp posts, completely built-in innovative installations.

Operation and maintenance of photovoltaic systems (O&M)
In order to guarantee the expected economic return and obtain positive results, it is necessary to pay particular attention to the organisation of maintenance and operation activities.
For this reason Selettra, which has carried out maintenance and operation activities of photovoltaic systems for years, has created a special service structure with competences, instruments and organisation which make it possible to efficiently carry out the services and maximize the production.
The experience developed over the years has shown that photovoltaic systems with different technical and installing characteristics have operation and maintenance needs that can be different remarkably.
For this reason Selettra has created a flexible service structure which can adapt to each client's specific needs and always tries to improve its performance. According to our clients' needs and the characteristics of the systems, we can offer administrative assistance and multi-level maintenance programmes, from single interventions in case of specific problems in small house systems (post selling assistance), to “product warranty” contracts undersigned after the supply of medium and big commercial use systems, to complete O&M contracts with performance guarantee for ground-based photovoltaic parks.
