06/08/2008 - Increasingly there is a growing practice of providing new buildings Monthly solar thermal systems for the delivery of hot water for sanitary purposes (ACS), which meets the needs of all the apartments up the building, resulting in many benefits from the technical point of view (the system is already planned and optimized in the design of the building and as such avoids the stages of adjustment to the structure if it already exists) and economic (the incidence the cost of installation per unit is lower than in the case of most individual plants and independent).
Certainly the production of hot water with solar panels, you can get, with considerable advantages, including a condominium, because the capacity is smaller. It can indeed, in this case, reduce the use of the boiler is located, reducing the cost of maintenance.
Photovoltaic systems (Fv) for the production of energy from solar, to be connected to the general distribution network, are the subject of recent economic incentive. The current legislation (DL 19 febbraio 2007) disciplina i criteri e le modalità per incentivare la produzione di energia elettrica mediante la conversione fotovoltaica della fonte solare. Tale decreto prevede che gli incentivi per la costruzione degli impianti vengano erogati in "conto energia".
Anche un condominio ha la possibilità di installare un impianto fotovoltaico . Si possono seguire due differenti percorsi: o un singolo inquilino decide di costruire un proprio impianto fotovoltaico allestito nelle parti comuni, o vi provvede unanimemente la totalità dei condomini. In entrambi i casi è necessaria l’autorizzazione dell’Assemblea. E’ importante sottolineare che, oltre al risparmio sulla bolletta elettrica, il nuovo sistema offre una considerevole opportunità di guadagno. Infatti un impianto di circa 50KW produce un guadagno medio di 3000/3500 euro al mese: questo budget una volta superato il Pay Back Period potrà essere utilizzato per ridurre ulteriori costi di gestione del condominio oppure suddiviso tra i condomini.
Ogni singolo condomino può comunque installare sul tetto condominiale un impianto solare per uso privato purchè rispetti alcune regole. Spesso accade che i condomini siano diffidenti verso l’installazione di solari, perché esistono molti pregiudizi.
L’installazione sul tetto dei pannelli solari non provoca innalzamento della temperatura nell’appartamento sottostante, Indeed, this apartment will have significant benefits in summer due to the installation of the panels that need air circulation to their cooling.
The solar panels do not spoil the architectural appearance of the building . There are panels on the market that fit perfectly with the architectural lines of any building and which do not detract from its appearance. Indeed, it is to say that installing a solar system increases the market value of the building. Therefore, if the installation of solar energy does not change the appearance or the substance of the building, may request and obtain any condominium to install a plant for their own use. If
facilities for private use any costs of installation maintenance and repairs are charged to the owner, while in case of use of panels of all buildings, including the allocation of costs is based on shares thousandth. To install a solar roof on a condominium must, at the office of the town, a complaint to start the work, accompanied by a technical report.
