This project envisaged the reclamation of the main office building cover, through the complete removal of the asbestos cement that constituted it, and the new covering with the integrated installation of Sanyo Hit HDE4 photovoltaic modules.

Another example of a project for a major reality, local TV, is the Practical and versatile, making it suitable for any application; Simple, making it ideal for installation in existing systems; Relevant data transmission though the AC and DC power csi systems, without the need of dedicated networks, such as RS 82-255 Easy system wiring; Reduced costs for materials and man hours; Electric parameter control of the strings; String box component status control; Dialog possible with decentralized inverters on request ; Constant control of required parameters, displayed in real time on the monitor; Record xei controlled parameters and storage in archive; Routine programmed maintenance day and night; Easier special maintenance thanks to instant fault control, reducing partial or total inefficiency to a minimum; Compliance with the technical standard CEIfor design, installation, checks, testing and photovoltaic plant monitoring criteria.

The system assists any type of plant controller for constant monitoring of productivity dei possible causes of inefficiency in real time. In PV plants, with power not higher than 20 kW and with maximum three inverters, to which loads for stand-alone operation are not connected, the generator device can also accomplish the function of interface device 8225 4.

Canopy with photovoltaic cover. One of the first examples of photovoltaic in Italy, the Capo Colonna plant has been completely reconstructed by Geotech Engineering, replacing modules and inverters and re-wiring harnesses.

From the inspection to installation, the photovoltaic kit to produce renewable energy in the home and reduce consumption. Testimonials of the strong desire to meet the needs of the customer by Geotech Engineering, in this case were used pieces specially designed for integration on greek surfaces. You just have to have a space available on your cdi roof 82-225 we think to all the rest.


For installations up to 20kW the interface function can be carried out by more different devices up to 3 Guide for the connection to the electrical networks by Enel Distribution. The interface protection system, which acts on the in- terface device, is constituted by the functions listed in the Table 4.

Renewable energies Alternative energy is a form of energy derived from sources that, according to a human perspective, are not likely to run out, that is, they are regenerated constantly, for example, solar, hydroelectric, wind energy, energy from wood wood, biogas and geothermal energy.

As regards the opening command of the main device due to the intervention of the main protection, an undervoltage coil must be used because if, for any reason, the supply voltage of the main protection lacks, the opening of the main device occurs also in case of absence of the com- mand coming from the main protection.

Example of a typical collaboration by Geotech Engineering with small and medium-sized companies is the Crotone Snam projects Example of collaboration with a large Italian company, Geotech Engineering cares for the maintenance of a photovoltaic plant that Snam has made on the roof of the Hera Lacinia Museum, near Capo Colonna.

From inspection to installation, photovoltaic kit to produce renewable energy and reduce consumption. There are numerous examples of synergies between Geotech Engineering or public interest organizations. PMI Example of a typical collaboration by Geotech Engineering with small and medium-sized companies is the The interface device can be positioned both on the MV as well as on the LV side.

For plants with total generated power not higher than 20kW such separation can be replaced by a protection generally inside the electronic control and setting system of the inverter which makes the cel or generator device open in case of val- ues of total direct component exceeding 0.

10 Photovoltaic plants

For plants with more PV generators, as a rule, the inter- face device shall be one and such as to exclude at the same time all the generators, but more interface devices are allowed provided that the trip command of each protection acts on all the devices, so that an anomalous condition detected by a single protection disconnects all the generators.


This project envisaged the reclamation of the roof covering of the main building, an industrial warehouse, through the complete removal of asbestos cement that constituted it, new roofing, minilled on Y-beams, with the compilation of photovoltaic modules MAGE Solar Powertec Plus You just have to have a space available on your company roof.

Data Sheet System Software Web 2. Geotech Engineering presents the new photovoltaic offer.

Read more This project has foreseen, on a pre-existing sheet metal roof, the installation of the photovoltaic solar field to be plotted to the ground and integrated into it. It has been developed in two solutions: Civil works in general are not included and the structural stability of the buildings with the installed photovoltaic system and site accidental reference loads snow, wind, etc. In addition, with one of the proposed forms of funding, the energy bill will cover the annual amount of the installments.

Few moves to save: Smart Control is a monitoring and control device that allows the current of each photovoltaic system string to be measured, identifying performance and energy production levels through a special software included with the device. In addition, the study of the most appropriate solution has always been linked to the verification of a financial plan based on available incentives or lower consumer spending.

Two projects that represent a fruitful collaboration between Geotech Engineering and people of public interest are the Geotech Engineering offers two types of installation, depending on the needs: Photovoltaic and asbestos disposal Example of a typical collaboration by Geotech Engineering towards nursing businesses is the 48,86 kWp plant of the Carlesi Vivai di Piuvica PT plant.

Photovoltaic canopies Geotech Engineering offers two types of installation, depending on the needs: The peculiarity of the project is represented by the cek inclination of the new flap in order to place the solar photovoltaic field in the condition of having a better performance, obtained through a restrained substructure on the reclaimed cover. Data transmission of the power line patented ; RS Modbus data transmission. Example of a typical collaboration by Geotech Engineering towards nursing businesses is the 48,86 kWp plant of the Carlesi Vivai di Piuvica PT plant.
