Residential plants

Through the availability of a photovoltaic system and an energy storage system, it is really possible to achieve total energy independence. This would mean no more gas meters and, therefore, no more bills. The correct balance between a Thermal and an Electric project can ensure total energy independence.

We are able to achieve this goal based on the actual needs of the client and the compatibility of existing heating systems or, in the case of new homes, through detailed design of new technological solutions that can ensure absolute energy independence and self-sufficiency.

Photovoltaic and Storage Plant

The main assumption is that we have a total space of at least 40 square meters for the construction of a photovoltaic system of the power of 6 kwp. Photovoltaics at night produces nothing, however, we can take advantage of the energy produced during the day by using a storage system that can fulfill, uninterruptedly, every energy need.

The Energy Storage system ensures great savings in the bill as it reduces the withdrawals from the grid, making available the self-produced energy, clean energy, more efficient and, above all, cheaper. It is a home storage solution that helps to considerably increase the share of household self-consumption through intelligent management of energy produced, consumed and stored.

A photovoltaic system connected to a storage system provides maximum savings in utility bills.

The system consists of a central inverter, a controller that optimally manages energy flows, and an accumulator with lithium-ion batteries.
An increase in self-consumption corresponds to identical value in lowering electricity bills.
The standard system has a nominal storage capacity with lithium-ion batteries of 6.4-9.6-12.8-16-19.2 kwh, which corresponds to enough electricity to provide autonomy for each household need.
The batteries have a life of more than 20 years.
With Energy Storage, 100% autonomy from the public grid is achieved in summer, while, in winter, up to 70% energy self-sufficiency can be achieved, intelligently regulated by the consumption optimization system.
For a typical family of 4-6 people, the storage system can range between 6 and 9 kwh, obviously conditioned by “good or bad” energy habits. Our storage system, with a minimum of 6kwp installed allows you to totally eliminate the connection to the Gas grid.
The management system provides, automatically, for optimal charging and discharging of the batteries, a necessary condition for better efficiency and durability.
Monitoring of the plant via a dedicated web portal is provided.
Insurance coverage for 10 years and maintenance are included in the cost.

Stove and Kitchen

Adequate design of storage systems makes it possible to ensure the need for hot water 24/24h through the installation of a boiler and a heat pump dedicated to domestic hot water. Thus, the conditions of hot water usability are not changed at all, and most importantly, thanks to the Energy Storage system, the cost is zero.

Sanitary Hot Water

Heating and Air Conditioning

With stove and hot water costs eliminated, Gas bills are a particularly sensitive item in the household budget due to heating. The Energy Storage program involves the replacement of the old boiler with a heat pump with -20° + 65° operating characteristics with the aim of powering the heating system, which can be underfloor or existing thermo-convectors (subject to the compatibility of the latter with the System).

The system involves the use of the latest generation of thermo-convectors capable of operating with circuit temperatures of 30°- 35°- In the presence of traditional radiators it will be necessary to replace them with the thermo-convectors described above. The heat pump is powered by the Energy Storage system through the energy production and storage system. Of course, the same Heat Pump also provides summer air conditioning or cooling of the house. The underfloor system benefits from cooling, while the convector heaters provide air conditioning. Therefore, the size of the capacity of energy accumulation, in the standards described above, will be calculated on the basis of the overall projected energy demand for all types of consumption.

Medium large plants

In addition to domestic users, Ei Systems Energy also caters to artisan and industrial users using the THREE-PHASE system. Therefore, it is possible to design an energy storage system for any installed power, even in OFF-GRID Through its technicians, Ei Systems Energy is at your complete disposal for any further information, calibrated to your energy saving and efficiency needs.

Photovoltaic Shelters

Ei Systems Energy has designed an innovative solution for roofing outdoor parking spaces to generate electricity through the presence of photovoltaic modules.

Stationary System

This is the traditional system, i.e., the one that involves the installation of fixed structures on the ground at an angle of about 30° to the horizontal and perfectly exposed to the south.

Photovoltaic modules capable of converting the sun’s rays into electricity are then installed on these structures.

These systems are suitable for land with medium to steep slopes and have relatively low operating/maintenance costs.

Pursuit System

An advanced, technically viable and economically competitive structure, the single-axis photovoltaic tracker allows photovoltaic panels to track the movement of the sun from east to west.

The solar tracker is easily adaptable to different PV array configurations, this allows the power generated by each individual array to be maximized, thus optimizing the overall efficiency of the system.

Single-axis trackers consist of a single horizontal or vertical rotation axis. These systems track the sun along a single axis, which means they can rotate in an east-west direction with a ground clearance of 1.2m at an angle of 54°.

These devices, in combination with bifacial PV panels, offer a significant performance improvement over fixed systems (27 to 30 percent) as they follow the path of the sun from sunrise to sunset.

This system is particularly effective in regions where the amount of sunlight varies significantly throughout the day it is possible to enjoy some advantages:

Increased conversion efficiency;
Decreased solar panel area for the same amount of energy produced.

Choosing the right solar tracker system varies depending on a number of factors to consider including

Size and characteristics of both the structure and the location where the tracker is installed;
Latitude, local weather and climate conditions of the environment where the technology is installed.

Agrivoltaic

Agrivoltaics is a system consisting of a photovoltaic system placed on land that is used at the same time for livestock or agricultural activities. It is not just a sharing of space, but an integrated solution that can generate benefits for both sectors.

This co-presence of agriculture and solar panels ensures an efficient and inclusive use of land while promoting the recovery of abandoned land. In this virtuous circle, land productivity is in no way affected and the same soil is exploited for two different and complementary purposes.

These are tracking structures with a minimum height from the ground of 3m at 54° inclination.

The minimum wheelbase in these cases is 6m, so that agricultural vehicles can pass through with a special system that puts the modules at a minimum of 4m above the ground if needed.
