Years of effort, investments, calculations and documents to browse to hunt for possible bonuses. And in this precise case we are talking about the so-called invoice discount of 50 percent. Then comes the time for the works, which materially consist of the installation of the photovoltaic panels on the roof of the house. Money that goes away, but with the prospect of saving and safeguarding the environment. Then another wait, which sometimes seems eternal. In fact, the time between installing the panels and actually putting the system into the network consists of months. Not in days. And finally the bitter surprise: the infrastructure is not always able to “withstand” thepower that the panels input into the system. And the system stops, effectively causing the citizen to lose part of the benefits guaranteed by energy autonomy. It is the complaint of a citizen of Veneto river, in particular. But the problem unfortunately concerns a good number of private systems.
WHAT HAPPEN
The person who addressed the Gazzettino editorial team was a woman who lives in Fiume Veneto. In front of her a table full of documents. These are all the papers that were necessary to install and operate a domestic photovoltaic system. The story begins in 2022, but it is now that the most important problems have emerged. «The voltage of the public network – explains the citizen – is out of tolerance and causes the plant to shut down. The same thing then starts again after 20-30 minutes.” But in the meantime that half hour has been lost, as have the benefits of the energy that would otherwise have been correctly put back into the grid. A problem, explain some experts contacted, which does not fall within the typology of systems installed on the roofs of homes, “but which refers to the general network”. In some cases data, especially in ancillary areas.
THE OUTPUT
The story of the Pordenone town starts in 2022, when the procedures necessary to install a photovoltaic system on the roof of your home in Fiume Veneto begin. «In detail – he explains – it is a roof made up of sixteen photovoltaic panels capable on paper of delivering a power of 6 kilowatts, for a production of 24 kilowatt hours. A level – explains the citizen who complains about her conditions – which however can almost never be reached. The average calculated and reported by the meters, in fact, does not exceed 15-16 kilowatt hours. And the disservices – he continues – are concentrated above all in the peak time slot, i.e. from midday to three in the afternoon”. Exactly when the sun is most perpendicular and when the usefulness of the panels should be greatest. Always on paper, because then you have to come to terms with the line’s ability to absorb the energy put back into circulation.
«The disservice I’m talking about – the woman continues – affects me like many other citizens who are equipped with a storage battery combined with the photovoltaic system installed on the roof of their home. In fact, those who don’t have a storage battery don’t notice the gaps.” In fact, the current doesn’t cut out completely. The effective capacity of the system to introduce energy into the public grid is “simply” lost. Is it just a few minutes a day? And the sum, in this case, makes the difference. And considering the cost of the systems it is absolutely not “peanuts”. Without calculating the difficulties and long times to obtain the economic surpluses of putting energy into circulation. But this is yet another story.
