EVA v/s POE Encapsulant – Who Wins The Battle Of Solar Panel Protection?
The queries have been overwhelming for a while.
For the uninitiated, the EVA or Ethylene Vinyl Acetate is a traditional kind of encapsulants for solar panels. These are cross-linkable, durable, and transparent in nature.
However, over the period, the popularity of POE is rising significantly. With their own arguments backed by substantial information, the experts are fighting it out about the effectiveness of POE or PolyOlefin Encapsulant over EVA Encapsulant. So, who’s right and who’s wrong? Let’s find it out.
Even the experts agree to the fact that EVA encapsulants were hard to emulate. But, a few companies have emerged with reliable and advantageous solutions in POE encapsulants. A noticeable drawback of EVA encapsulants was its inability to resist UV Rays, which is why a front glass was required.
The POE Encapsulant has been in the line of innovations and available in several versions. The advantages it offers include:
Improve thermo-mechanical properties for durable performance in and out.
UV cut-off, which means it protects the solar panels from getting damaged from UV Rays.
Chemical inertness is another feature that prevents corrosion due to acid gas.
Improved PID (volume, heat, and humidity) resistance for superior performance.
Higher volume resistivity to prevent the current leakage from the insulating material.
Well, the above features qualify the POE encapsulant as a top contender in the marketplace.
You can find a good number of reputable and reliable companies offering a variety of solar panel protection products, which include innovative encapsulants (that qualifies the above points), positioning tape, and adhesive solutions, etc.
