Install a photovoltaic system should still? This is the question that many now do, especially since, back in 2013, the incentives of the tariff “giving way” to the tax deductions are over. From 2008 to 2013 we were introduced 5 different “tariff” in five years that have created some confusion and continuing regulatory uncertainties.
How it worked the incentives for photovoltaics
In times of incentives you purchased the plant, which at that time had very high prices (up to 7,000 € per kWp turnkey), they did demand Shared Authorization for construction, we were the practical connection with ENEL and They made the required incentives to GSE practices; with the approval of the GSE, for every kWh produced by the incentive fee was paid. With “net metering”, in addition to incentives was (and still is) the compensation between injections and withdrawals of the electricity network, in addition to the benefits of farm consumption: in practice, instantly consuming self-produced energy is avoided drawings from the grid with the resulting savings in the bill.
This system has created, for better or for worse, a veritable boom in the Italian photovoltaic taking it to be, in a few months, the world’s first market.
Photovoltaics in 2016
Today incentives are terminated and the “investment model” related to photovoltaics has completely revolutionized, both for large industrial plants, both for small residential systems. In any case, and it is something to be reckoned with, the counterpart of the end of the incentives was the sharp drop in prices of the installations, up to more than 2/3 compared to the first incentive photovoltaic (now spends up to less than 2,000 euro per kw “keys in hand”).
Therefore, today, the relationship between costs and benefits of investing in a photovoltaic system is not all that different, and re-entry periods of the initial expense can be considered very similar.
So, it can certainly be said that the photovoltaic today can still be convenient, but a fundamental condition, namely the ‘consumption. It is no longer to produce “energy as possible” to get immediate gains, but to produce the energy necessary to the fulfillment of their demand for energy.
Photovoltaics is still affordable today if installed in view of farm consumption, ie, the savings in the bill becomes the “Gain item” relevant, which can be guaranteed with the self-production of energy. Ultimately, the real convenience photovoltaic investment today there is no absolute way to answer, but there are some conditions of installation and use of the system that make the transaction more or less attractive investment in terms of the ratio between costs and benefits .
In addition to purely economic speeches, you should focus attention and give due importance also to environmental and collective convenience is there for all how to produce energy with photovoltaic ports lowering gas emissions resulting from the combustion of fossil fuels. Reducing emissions has its positive effects on public health and on the health of the territory.
The PV affordability is relative to at least 6 factors:
• the current price of the energy bill: the more the energy costs in the bill, the more affordable autoprodurla with photovoltaics
• the cost of an installation “turnkey” and a possible accumulation system: the more the price of installation is low, the sooner you will be able to write off the cost of the rapid
• the increase in energy costs over the next 25-30 years (inflation, depletion of resources, international geopolitical balance): the electricity price growth trend
• the amount of producible energy from my system for the next 25-30 years: according to the different installation modes and the region, ranging from 1,100 to 1,500 kWh per kWp per year
• the amount of energy that are able to autoconsumare and enter the network: agrees autoconsumare the energy produced, avoiding as much as possible the withdrawal of the ENEL electricity network
• the presence or absence of incentives, public contributions or tax deductions: the photovoltaic and battery storage systems for domestic consumption are deductible at 50% when contemplated as part of a building renovation, halving the actual cost of the plant and its amortization period
In conclusion, the self-consumption, if properly exploited, can considerably reduce the purchase of electricity from the grid, energy costs minimum € 0.20 / Kwh. We must therefore take advantage as much as possible the free energy self-produced and self-consumed. We consider that the price of the energy bill is still very dependent on imports of raw materials and it is still too dependent on taxes, “service charge”, etc ..: the electric self “puts away” from energy price increases electricity. A final advantage of photovoltaic systems is ultimately tied to the low operating and maintenance costs that contribute, compared to other forms of generation, to keep the payback times of between 6 and 12 years.
