Project Description

Photovoltaic is a way of producing electricity that does not use or emit substances harmful for the environment. It is among the commonly called “clean energy production systems”.
A photovoltaic plant is an electrical system essentially consisting of the assembly of several photovoltaic modules that exploit the incident solar energy to produce electricity by photovoltaic effect, the necessary electrical component (cables) and electronic (inverter) and possibly mechanical-automatic systems Solar tracking.
Technologies surrounding photovoltaic plants are numerous and constantly evolving, one of the latest novelties of importance is the “photovoltaic with storage


Operation of a Photovoltaic System with Storage, Day and Night

In a very simple way, a Photovoltaic System produces electricity which, if not completely consumed inside the home, should be poured on the power supply and resold during the irradiation hours.
Unfortunately, the greatest power consumption occurs at night hours, where solar radiation is lacking. For this reason, the most logical solution to try to exploit the current produced during the day from its photovoltaic plant is to associate the system with a battery capable of storing the current needed to meet the night energy requirement.
Essentially, we have two types of photovoltaic storage:
Inverter with accumulation: The accumulator, usually lithium, is assembled in the same body as the inverter, occupying very little space. The impact is minimal, both in aesthetic terms and in terms of adaptation works.
External battery pack: This solution is typically adopted when using Lead-Gel batteries or in case, when cheaper but very bulky accumulators are used that require space and complex installation work.
A photovoltaic system equipped with Inverter with Accumulator behaves dynamically during the day.


ON MORNING: The energy produced is consumed directly at home and the excess is stored inside the accumulator
IN THE AFTERNOON: when the battery is charged, the excess electric energy is input into the power grid and sold.



IN THE EVENING: The energy accumulated in the battery comes slowly
used inside the home to power household appliances.
DURING THE NIGHT: in case the energy stored in the accumulator was not
enough to satisfy all requests, the system supplies itself from the grid.




Why should I install Photovoltaic Solar Panels with Storage?

The Energy Account gives a higher incentive rate for self-consumption of self-produced energy from its domestic photovoltaic plant. So, in order to get the best economic benefit and maximum savings in the bill, you should concentrate more on your house’s electrical consumption during the day, ie when photovoltaic panels are in production. However, as we all know, most of the electricity consumption is concentrated during the night hours when we are at home. The photovoltaic plant does not produce electricity during the night, because of course there is no solar irradiation. For this reason, in the absence of an electrical accumulation of electricity, in the evening and at night we would be forced to supply us only from the electricity grid, paying the current at a fair price and losing all the benefits offered by the incentive rate.


If during the day your family spends many hours outside the home, maybe for work, and electricity consumption is concentrated during the night, to implement a Photovoltaic System with Accumulation is a convenient and smart choice. In this case, as electric power consumption is concentrated in the evening and at night, the accumulator is a real gold mine and allows you to maximize self-consumption making the most from the photovoltaic system installed on the roof .

Changes in Self-consumption thanks to photovoltaic accumulation

Thanks to a state-of-the-art accumulator designed to guarantee long-lasting energy efficiency, such as lithium accumulators in inverters with accumulators, it is ultimately convenient to use even in the night electricity from solar panels produced during the day.

Can I really save up to 100% in Bill using Accumulator?
With a battery-provided photovoltaic system it is really possible to reset the energy component of the bill entirely. It is important to note that fixed fees can not be cleared and will continue to be due to your own electricity provider.
Obviously, the percentage of savings depends heavily on your family’s consumption habits. By concentrating the use of electricity more on daytime, when the plant is in production and the battery is already charged, in the evening, the accumulator can be able to meet all the needs of the home, especially if the plant is properly dimensioned. In this way we are no longer supplied from the outside grid and the energy component of the electric bill is reset.

Photovoltaic System with Accumulation: Ideal for Mountain or Country Houses

A photovoltaic system with accumulation is very well suited to be installed in those situations where no electricity connection is present or if you want to be completely independent from any supplier.
A typical case of using battery-powered systems is that of mountain or country houses that are completely isolated and disconnected from the grid. This type of photovoltaic systems with accumulation is also defined as stand-alone or off-grid, as the plant is disconnected from the mains power supply and self-sufficient. With an island system, that is, disconnected from the network, you are completely independent of the manager (Enel, Acea or others) and you do NOT pay any bill.
The accumulator also guarantees the power supply even during the evening and the night, using clean and 0 impact energy, as long as the battery is properly dimensioned to meet all the absorption requirements that occur during night time. Since there is no network connection, there are no fixed charges, network charges, or other charges to pay for using electricity in the home.
