Buoni Pannelli Fotovoltaici - Come Identificarli

20-30 years product warranty: High-quality photovoltaic panels usually come with extended warranty periods, ranging from 20 to even 30 years. A long warranty indicates the manufacturer's confidence in the durability and reliability of their product.

Favorable warranty terms: Pay attention to the warranty conditions offered by the manufacturer. Premium panels often provide coverage for the period during which the modules maintain high performance, and they offer support in case of any potential issues.

Representation in Europe: Having a manufacturer's representative in Europe ensures smooth communication and efficient handling of formalities. It reflects the company's commitment and professionalism in serving the local market effectively.

Over 10 years of production experience: Manufacturers with extensive experience in producing photovoltaic panels are more likely to design high-quality and durable products.

Higher price: Premium photovoltaic panels usually come at a higher cost than lower-quality ones. The higher price reflects the use of better materials, advanced production technology, and the assurance of a longer product lifespan.

Fill Factor (FF) above 0.8: The Fill Factor represents the efficiency of the photovoltaic module. A value above 0.8 indicates a high level of performance and efficiency in the panels.

Temperature coefficient above 94%: Premium modules exhibit high resistance to temperature fluctuations, resulting in better performance in various weather conditions.

Tested under tougher conditions than required by certifications (e.g., PVEL): Manufacturers subjecting their photovoltaic panels to additional testing under demanding conditions demonstrate confidence in their product and a commitment to delivering top-notch solutions.

Less than 10 years product warranty: Photovoltaic panels with short warranty periods may indicate lower quality and less confidence from the manufacturer.

No representation in Europe and unstable distribution: Manufacturers without a presence in Europe may hinder communication and resolution of potential panel-related issues.

Recently started their production: New manufacturers may not have a fully established production process, and the quality of their panels may be less certain.

Suspiciously low price: Low-priced photovoltaic panels may raise concerns about their quality. Cheap panels often utilize inferior materials or technology, resulting in lower efficiency and a shorter lifespan.

Fill Factor (FF) below 0.72: A low Fill Factor indicates lower energy conversion efficiency from solar to electrical energy.

Temperature coefficient below 90%: Modules with lower temperature resistance may be more susceptible to degradation and loss of efficiency in challenging weather conditions.

Modules purchased outside official distribution channels: Buying photovoltaic panels outside official distribution channels carries the risk of purchasing counterfeits or used modules with potential damage or reduced efficiency.

Choosing unreliable installers: Even good photovoltaic panels can underperform if poorly installed. Choose a trustworthy and experienced installer to ensure a professional installation.

Garanzia del prodotto inferiore a 10 anni: I pannelli fotovoltaici con periodi di garanzia brevi possono indicare una qualità inferiore e minore fiducia da parte del produttore

Nessuna rappresentanza in Europa e distribuzione instabile: I produttori senza presenza in Europa possono ostacolare la comunicazione e la risoluzione di possibili problemi legati ai pannelli

Hanno avviato la loro produzione di recente: I nuovi produttori potrebbero non avere un processo di produzione completamente stabilito e la qualità dei loro pannelli può essere meno certa

Prezzo sospettosamente basso: I pannelli fotovoltaici a basso costo possono sollevare dubbi sulla loro qualità. I pannelli economici spesso utilizzano materiali o tecnologia inferiori, risultando in una minore efficienza e una vita utile più breve

Fattore di riempimento (FF) inferiore a 0.72: Un basso fattore di riempimento indica un'efficienza di conversione energetica inferiore dall'energia solare all'energia elettrica

Coefficiente di temperatura inferiore al 90%: I moduli con una minore resistenza alla temperatura possono essere più suscettibili a degradazione e perdita di efficienza in condizioni meteorologiche difficili

Moduli acquistati fuori dai canali di distribuzione ufficiali: Acquistare pannelli fotovoltaici al di fuori dei canali di distribuzione ufficiali comporta il rischio di acquistare contraffazioni o moduli usati con possibili danni o efficienza ridotta

Scegliere installatori non affidabili: Anche i buoni pannelli fotovoltaici possono dare prestazioni inferiori se installati in modo non adeguato. Scegli un installatore affidabile ed esperto per garantire un'installazione professionale
