How to determine a quality solar panel

When making the decision to install a solar power system on your roof, it is crucial to do sufficient research to make sure you install a high performing and quality system to make the high upfront investment worth your while. The quality of a solar PV system is an important factor to consider for any solar project – be it residential or for a business. Indeed, the quality of the solar PV modules chosen by a new solar buyer will determine the return on investment time of your solar power plant by guaranteeing you an optimal production of solar energy in the long term.

Choosing the right solar panel can be tricky especially with the large variety of options available in the Australian market. It is difficult for a new buyer to check the quality of a solar panel only with a verification of the visual appearance. In order to truly determine the quality of a solar panel, it is necessary to review several factors such as standards and technical specifications to ensure the reliability of a particular solar panel brand.

At One Solar, we deal with only the most premium and quality solar systems. This blog helps you explore the top 10 criteria to determine the quality of a solar panel that will help you to define the choice of your Solar PV panel based on your energy needs. Investing in a premium solar panel will help to ensure a long term return on your investment.

The manufacturing and production of solar photovoltaic modules is dictated by several standards required by the IEC (International Electro technical Commission) in order to be approved to be marketed on the international market.

These standards set by the IEC are as follows:

  • The standard IEC 61215 (crystalline) or IEC 61646 certifies a guarantee of quality in terms of respect for electrical parameters and mechanical stability. The requirements of this standard refer to the qualification of the design and approval of photovoltaic modules for land application and for long-term use.
  • The standard IEC 61730 specifically addresses the topics of prevention against electric shock, fire hazard and bodily injury due to mechanical and environmental constraints. This standard set by the IEC, whose specificities concern the safety aspects of the modules, complements the IEC 61215 standard, which fixes the electrical performance of the solar panels.

By making sure that certain standards are met in the manufacturing of solar PV panels, high performance and quality can be assured to the potential buyers. Normative standards are a guarantee of reliability for solar photovoltaic modules. It is also necessary to have proper documents like warranty certificates that should be provided by solar installers. All certified solar manufacturers are able to provide solar buyers with the quality certificates and warranties for the solar panels they offer. There is also the possibility to directly download the certificates and attestation of conformity and test directly on the website of the manufacturers. A fine examply of this service is provided by one of the premium solar panel brands – Qcells.

The TUV certificate ensures that the photovoltaic module has successfully passed the rigorous tests carried out by the German TUV laboratory (Technischer Überwachungsverien) proving its resistance to extreme temperatures, accelerated aging cycles, violent splashes and fire. This testing is necessary and the results of this test can help distinguish a premium quality panel from a cheaper one.
