Solar Module


The photovoltaic (PV) industry has experienced incredibly fast transformation after year 2000 as a result of extraordinary technology breakthroughs, from the material level up to large-scale module manufacturing.
With the PV industry expected to grow consistently in the coming years, some questions are capturing the attention among market operators:

⦁ What constitutes a “good quality” module?

⦁ How “reliable” will it be in the field?

⦁ Efficiency of Modules?

                Solar PV panels are subjected to a variety of tests. Via the solar panel tests, safety and compliance with the minimum quality standards are checked, of which passing is a precondition to getting approval for the solar modules. Advanced performance and quality tests help the user to choose the right solar panel type.
One of the most important solar panel testing procedures is the IEC certification. It indicates that the solar PV modules comply with individual safety, quality and durability requirements. In these tests, the solar PV panels are subject to various loads, which are defined by the so-called ICE standards. The standards were established by the International Electrotechnical Commission (IEC) in Geneva.
The IEC certificate provides the basis for the trading of solar PV panels. The IEC certification determines the basic solidity of solar PV panels and thereby ensures the functionality and safety of solar PV systems, and so, the essential operating requirements of solar PV panels.
Modules are labeled to confirm passing the applicable suite of IEC qualification tests Although sometimes used to infer module lifetime, not designed to do so; alternative ways being developed to perform accelerated aging testing The performance PV standards described in this article, namely IEC 61215 (Ed. 2 – 2005) and IEC 61646 (Ed.2 – 2008), set specific test sequences, conditions and requirements for the design qualification of a PV module.

Environmental: Temperature cycles, Humidity freeze, Damp heat.
Mechanical: Mechanical load, Robustness of terminations, Hail impact.

Safety standards IEC 61730

Electrical hazards: Dielectric withstand, Ground continuity, Accessibility, Cut susceptibility, Impulse voltage, Reverse current, Partial discharge.
Mechanical hazards: Module breakage.
Thermal hazards: Temperature test
Fire hazard: Fire resistance

  Solar Panels Efficiency
Some Solar Panels are more efficient and it also depends on the dimension of Solar PV (L*W) . For example Solar Panels made by Genus are the most efficient which means they require less area. For space constrained homes, they are the best with more per watt hour of electricity generated. Many Chinese PV manufacturer don’t have the certification from IEC. Consumer pay less price for PV and generate less power
