Dobre Fotovoltaične Ploče - Kako ih Prepoznati

Characteristics of Premium Modules

1. 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.

2. 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.

3. 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.

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

5. 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.

6. 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.

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

8. 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.

Characteristics of Low-Quality Modules

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

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

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

4. 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.

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

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

7. 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.

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

Zaključak:

Odabir pravih fotonaponskih panela ključan je za postizanje učinkovitog i pouzdanog solarnog sustava. Premijski moduli, s funkcijama poput produljenog jamstva, visokog faktora punjenja, otpornosti na temperaturu i testiranja u izazovnim uvjetima, služe kao bitni pokazatelji kvalitete. S druge strane, moduli niske kvalitete, s kraćim jamstvima i inferiornim tehničkim specifikacijama, trebali bi se izbjegavati kako bi osigurali uspješnu i održivu fotonaponsku instalaciju

Osim toga, zapamtite da čak ni najkvalitetnija oprema ne može nadmašiti loše prakse instalacije. Važno je pronaći uglednu solarnu tvrtku kojoj možete vjerovati za besprijekoran i uspješan solarni energetski projekt
