Median Salary Annual Canada

Fotovoltaico e televisione


E’ un rapporto difficile .
Quello tra fotovoltaico e televisione .
L’ultimo esempio risale a pochi giorni fa, domenica 1 novembre.
Va in onda Alle falde del Kilimangiaro , conducted with grace by Licia Colo , Rai 3.
During the program, Licia Colo explains how you can hold the energy consumption, thanks to the design and implementation of a passive house .
to illustrate in detail the advantages and benefits, Professor Claudia Bettiol , a professor at the Faculty of Engineering, University of Tor Vergata.
After showing an example of a passive house, the Bettiol switch to quantify the savings achievable .
But not just about savings.
Because, currently, in Italy, who install a photovoltaic system can even gain.
Verissimo.
But because you can earn, with a photovoltaic system? Why
addition to cost containment bill (electricity we produce it from us), thanks to the Energy Bill , you can sell excess electricity to the grid, earning about.
The concept is taken up by Licia Colo and repeated a second time by Bettiol, although she expressly referred to metering .
I do not know how many millions of people were watching the program at that time.
But surely the vast majority of them will have found yet another confirmation the mistaken belief that the convenience of the Energy Bill is due solely by the opportunity to sell electricity to the grid.
NOT 'SO' .
NOT 'TRUE .
First, the metering and network sales up 2 contractual arrangements, an alternative to the other.
That is, if you choose to join the exchange in place, you can not sell energy to the grid.
Second, the cost of photovoltaics comes dall'incentivo recognized by the state laws GSE.
Why? Because the GSE
incentive all the energy produced, not just the portion in excess respect to consumption.
And then, because the price of economic stimulus is far greater than the price of the sale.
Let the numbers, which perhaps is better. How much is
1 kWh of electricity produced by photovoltaic source?
depends on his fate.
1 kWh is encouraged from 0.353 to 0.480 Euro (depending, of course, the size and architectural integration of the photovoltaic component).
1 kWh saved is worth approximately 0.18 euros .
1 kWh sold is worth about 0.09 Euro .
UNDERSTAND NOW? But why
Italy is so difficult to correct television news?
