Investing in photovoltaics is worthwhile, regardless of the incentives. It is necessary to focus on the energy offered by the sun, not thinking exclusively of achieving grid parity.

Invest inThe photovoltaic is worthwhile, regardless of the incentives and the new Fifth Energy Bill. It is necessary to focus on the energy offered by the sun, not thinking exclusively about the achievement of grid parity. This is what emerged on the occasion of themeeting organized by Cogenergy in which he also took part Davide Chiaroni, of the Energy & Strategy Group, the latter made up of professors and researchers from the Management Engineering Department of Politecnico di Milano.
According to the expert, the so-called parity between the cost of producing renewable energy and cost of purchasing energy from the grid yes, it is a goal to aim for, but more simply the PV is also to be considered as a excellent investment. Why is it convenient? During his intervention in Fiorano Modenese, Chiaroni explained the differences regional of yields: a user who installs a photovoltaic system in the south will have an average yield of 8%, while a citizen who lives in the north of 6%. But those figures grow concurrently with the larger plants, for example from 400 kW of power, with 100% self-consumption and a cost of 1.300 euros per kW. In this case, the yield is 13% in the south and 8% in the north.
Under the technical profile of the analysis, photovoltaics have a fixed production cost but variable in relation to the geographical location or design choices, with a variable price (by type of customer and time slot) of purchase. For this there is a production risk in the face of a practically no purchase risk. To this must be added a potential which seems to be concrete decrease in the price of modules in the current three-year period, which runs from 2011 to 2013. According to the figures, costs fell by 42,6% in 2011 while the price decrease in 2012 was 31% and between 2012 and 2013 will be of '8% also due to the increase in requests.
In this case, explain Chiarone, “In reality, the concept of grid parity in practice takes on more of the meaning of an investment measure, since it includes a wide range of variables, such as the inconsistency of energy production by a photovoltaic system. And the numbers are starting to be reasonable “.
With or without tale energy.
