GEMLog Monitoring
The monitoring of solar plants in real time, 7 days a week including holidays, allows you to detect the economic, technical, and financial performance of your plant. This allows a timely intervention in case of failure or malfunction, avoiding production losses. The system consists of a low-power hardware appliance, installed in each photovoltaic system capable of acquiring data in a universal way. GEMLog provides a powerful web portal displayable on desktop, tablet and mobile, allowing you to check all the data listed above through the use of a fast and effective interface.
Ordinary maintainance
ORDINARY MAINTAINANCE
For the entire duration of the O&M contract, we perform the preventive maintenance of the plant providing all the services necessary to preserve it and ensure the proper operation of the solar panels. GEM proposes its own maintenance services aimed at preserving performance, safety, and prevention of normal deterioration and accidental failures.

Extraordinary maintainance
Extraordinary maintenance of a plant means all non-programmable interventions that involve the renewal and / or replacement of its parts, which do not substantially change its performance, but are intended to restore the photovoltaic system itself to ordinary operating conditions, which generally require the use of special instruments or tools, of non-current use and which, in any case, do not fall within the interventions related to the definition of new plants, transformation and expansion of plants and which do not fall within the ordinary maintenance .
These are interventions that, if required by the laws in force, may require the obligation of drafting the project by a qualified professional and that alternatively require a specific technical / professional competence.
Authorisation Management
If the production of electricity from photovoltaic solar energy is carried out in the absence of incentives, and without self-consumption, we introduce the concept of Market-Parity or Generation-Parity.
Basically, the Market-Parity indicates the production of electricity from solar photovoltaic sources in the absence of incentives, implemented by means of multi-megawatt photovoltaic power plants, whose economic value is represented by the value of electricity on the GME power exchange. It therefore indicates the trade-off between the cost of generating photovoltaic kWh LCOE (levelized cost of energy) and the price of electricity on the electricity market.
• Commercial negotiations and acquisitions of securities on land
• Verification of Local Authorities, Province and Region
• Technical checks, preliminary project realization, layout

• Management of the Municipal procedure, P.A.S., Provinciale, V.I.A. is
Single Authorization
Modules Washing
The mechanical system used for cleaning avoids contact with the panel in order to exclude any risk of abrasion, scratching or rupture of the washed surface hence optimizing the uptake of solar irradiation.
The system used adapts to the needs of each individual system and delivers water at a constant high pressure to be effective at considerable distances. Furthermore, the use of chemical products is strictly excluded for cleaning.
The water used for washing is treated, deprived of the saline component and the dissolved mineral substances. The service includes the thorough cleaning of the glass and its aluminium frames.
Plants Construction
The plants we manufacture are equally distributed both on the roof and on the ground in farmland and quarries. The plants built on the ground are both fixed and monoaxial. Each plant is customized by technology, materials used, type of installation and photovoltaic modules, based on the specific characteristics of the sites. All the choices, in the design phase, in the various phases, and in the procurement are always oriented to improve productivity and efficiency. Our goal is to achieve maximum customer satisfaction, respecting the highest quality standards and the best economic sustainability to yield our customers the highest return on the investment.
All the choices made during the planning stage in the various phases and in the procurement are always oriented towards greater productivity and efficiency and maximum customer satisfaction, always in compliance with the highest quality standards and the best economic sustainability to allow the customer the highest return of the product’s investment
ENGINEERING
Each photovoltaic project has different peculiarities depending on the different types of roof coverage, the morphology of the territory and the complexity of the requirements imposed by the electricity supplier and local authorities. Our experience allows us to develop the best technical-economic solution possible, following a thorough analysis of the case
PROCUREMENT
Our professionalism and experience allow us to provide our customers with reliable products at competitive prices. We guarantee maximum efficiency with regards to the choice of:
- Photovoltaic modules
- Support structures
- Single axial and biaxial tracking systems
- Central or string inverters
CONSTRUCTION
GEM takes care of the management and management of the site in all its aspects, monitoring the timely completion of the works. In particular, it manages the preparation of the site and the construction site, the movement of vehicles, people and materials, the construction of civil works and fencing, the connection to the network and the commissioning of the plant, in compliance with the safety regulations on construction sites
Revamping
The revamping is a set of technical and technological updating operations, which can affect both the individual components of the system and the components concerning its safety’s and supervision’s system.
The intervention allows the restoration of the performance of already installed and under-performing photovoltaic systems. This can become necessary for reasons attributable to errors in design or construction, due to serious deficiencies or needed maintenance, wear or damage to critical components due to the ordinary ageing of the installation, or due to major forces.
This process allows the revision and restoration of the original level of performance, which in specific cases can even be improved.
WHEN IS REVAMPING NECESSARY?
The revamping process is effective when the plant is no longer able to operate at its maximum efficiency, or in cases where they are no longer compliant with the regulations in force, CEI 0-21 and CEI 0-16, object of recent revision. Non-compliance with regulations does not only affect old generation plants: even many plants installed in 2010 may not meet the required criteria. Furthermore, revamping is effective in cases where the systems are dated and show frequent breakdowns, perhaps without being under warranty: in these cases, in addition to operational problems, there are also difficulties in finding competent personnel for assistance, and replacement parts.

Bolts Tightening
The control and tightening service of the anchor bolts of the structures and substructures of the photovoltaic panels is also offered. It is advisable to carry out this operation annually due to the continuous stress (wind, snow) to which the structures are subjected. This can lead to a change in the correct inclination of the photovoltaic modules themselves and loss of security.
Tightening of the screws of the structures: visual check of the tightening of the bolts of all the parts of the structures and revision of the tightening of the bolts subject to wear
Renewal of the painting of the structures: whenever the oxidation points need to be checked. The part will be stripped and sanded with sandpaper and repainted with a high anti-rust paint.
Checking the tightness of the electrical connections: all the electrical terminals must be checked without forcing the screws in order to avoid possible breakages, where necessary the terminals must be replaced immediately to avoid hot spots.
Other Services
Disinfestation
We offer disinfestation activities, with ecological and traditional means, to disinfest rodents and small animals that tend to undermine the efficiency and the general good functioning of your photovoltaic system.
