Anti-crisis photovoltaics: the importance of maintenance and the opportunities of revamping

9 January 2023


Europe is facing an unprecedented energy crisis, which has led to a worrying increase in prices.

Many companies will face serious difficulties in the coming months. In the current context, it is clear that a decisive shift towards renewable sources is no longer just an opportunity but a necessity. However, the installation of a good photovoltaic system alone is not enough. It is also essential to manage it optimally to maintain maximum efficiency and minimize extraordinary interventions, which inevitably result in production losses and, consequently, financial losses.

This is why it is advisable to turn to an experienced company that can provide an effective remote monitoring system and the expertise of designers, engineers skilled in problem analysis and resolution, dedicated photovoltaic electricians, and specialized data analysts who can guarantee targeted and timely interventions.

Many companies have already turned to Etica nel Sole to take advantage of their Operation & Maintenance service, which includes:

Monitoring – daily remote control to avoid costly system downtimes
Routine maintenance – planned and managed by expert personnel to minimize extraordinary interventions
Cleaning and thermography – professional module cleaning and precise thermographic analysis to optimize the system’s production capacity
Corrective maintenance – prompt intervention and repairs under constant supervision of the project coordinator
Administrative management – handling all mandatory administrative practices for photovoltaic system owners, essential for maintaining GSE incentives: from the Customs Agency, to the Network Manager, to ARERA, and to GSE
Technical check-up – verification of the system’s current technical (productivity, safety, regulations) and administrative status to preserve the entitled incentive

The most frequently proposed intervention by Etica nel Sole to its clients recently is undoubtedly revamping, which is the redesign of existing systems with partial or total replacement of components to extend their lifespan and increase productivity.

This is possible because new generation modules occupy less space, allowing additional power to be added and significantly increasing self-production of energy.

An example is a food production company in the province of Macerata, where a forward-thinking entrepreneur chose to completely refurbish their now obsolete photovoltaic system, adding additional power and increasing it from 100 kWp to 370 kWp. A forward-looking choice that today allows them to face the increase in electricity prices without compromising their business.

BEFORE THE INTERVENTION Location: Mogliano, MC System power: 100 kWp System type: rooftop Year of installation: 2010 Incentive system: Second Energy Account Problems: amorphous modules Last year’s Performance Ratio: -40%

INTERVENTION Type: total revamping of modules and inverters with an additional 270 kWp power upgrade. Installation of crystalline modules with inverters and optimizers.

AFTER THE INTERVENTION System power: 370 kWp Production increase: +83% on the revamped portion. Total annual production: 400,000 kWh
