Goede Fotovoltaïsche Panelen - Hoe Herken Je Ze

Good Photovoltaic Panels - How to Identify Them?

When looking for the right photovoltaic panels for your installation, it's essential to know how to distinguish high-quality modules from those that should be avoided. Almost all brands advertise their products as "premium," but that's not always the case. Let's explore the key characteristics to consider when choosing photovoltaic panels, ensuring that you make an informed decision.

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.

Eigenschappen van Lage Kwaliteitsmodules

  1. Minder dan 10 jaar productgarantie: Fotovoltaïsche panelen met korte garantieperiodes kunnen wijzen op een lagere kwaliteit en minder vertrouwen van de fabrikant

  2. Geen vertegenwoordiging in Europa en onstabiele distributie: Fabrikanten zonder aanwezigheid in Europa kunnen communicatie en oplossing van mogelijke paneelgerelateerde problemen belemmeren

  3. Onlangs gestart met hun productie: Nieuwe fabrikanten hebben mogelijk nog geen volledig gevestigd productieproces, en de kwaliteit van hun panelen kan minder zeker zijn

  4. Verdacht lage prijs: Laaggeprijsde fotovoltaïsche panelen kunnen vragen oproepen over hun kwaliteit. Goedkope panelen maken vaak gebruik van inferieure materialen of technologie, wat resulteert in een lagere efficiëntie en een kortere levensduur

  5. Vul Factor (FF) onder 0.72: Een lage Vul Factor geeft een lagere energieconversie-efficiëntie aan van zonne-energie naar elektrische energie

  6. Temperatuurcoëfficiënt onder 90%: Modules met een lagere temperatuurbestendigheid kunnen meer vatbaar zijn voor degradatie en verlies van efficiëntie bij uitdagende weersomstandigheden

  7. Modules gekocht buiten officiële distributiekanalen: Het kopen van fotovoltaïsche panelen buiten officiële distributiekanalen brengt het risico mee van het aankopen van vervalsingen of gebruikte modules met mogelijke schade of verminderde efficiëntie

  8. Kiezen voor onbetrouwbare installateurs: Zelfs goede fotovoltaïsche panelen kunnen ondermaats presteren als ze slecht zijn geïnstalleerd. Kies een betrouwbare en ervaren installateur om een professionele installatie te garanderen
