Frequently asked questions (FAQ)

 

CAN I PRE-CUT EVA LAMINATES AND LEAVE THEM READY TO USE?

Yes, as long as your facilities are air-conditioned and you can control the temperature and humidity at all times.

FOR HOW LONG?

We recommend not leaving them for more than 12 hours.

WHY DO I HAVE PROBLEMS WITH ADHESION OF THE MATERIAL?

The worst enemy of any encapsulant is humidity, and EVA is a highly hygroscopic material, so if we don’t maintain some strict storage standards, its adhesion properties will decrease daily due to water absorption.

IS GEL CONTENT IMPORTANT?

Yes and no. The photovoltaic industry mistakenly believes that gel content higher than 80% leads to reduced discolouration of the module, whereas the reality is that if the encapsulant is not correctly formulated or chemically enhanced, as SOLAPCAP products are, discolouration is inevitable when the module operates outdoors.

ARE SOLARCAP ENCAPSULANTS UL-CERTIFIED?

Yes. You may consult our certificates via our web site, or by following this link and searching for EVASA.

WHAT IS THE LIFE-SPAN OF SOLARCAP ENCAPSULANTS?

The shelf life of our products is directly related to the type of packaging. ‘Premium’ packaging allows storage for up to 9 months after the date of manufacture, while ‘Standard’ packaging allows storage for up to 6 months.

IS THERE A MINIMUM ORDER QUANTITY?

No. At EVASA we adapt to our customers’ requirements both in format as well as in quantity.

WHAT FORMATS ARE AVAILABLE?

We can manufacture products with thicknesses that range from 0.3 to 1.2 mm, the standard thickness being 0.46 mm. Laminate widths can range from 300 to 2100 mm. We also tailor cut the length of the rolls according to our customers’ requirements and we can produce rolls between 50 and 600 metres long. For other lengths, please consult our technical department.

WHAT IS THE DELIVERY PERIOD?

From 1 to 5 weeks, depending on the quantity and the delivery point.

CAN I REQUEST SOLARCAP ENCAPSULANTS CO-LAMINATED WITH ANOTHER MATERIAL?

Yes. We offer the possibility of laminating our encapsulant directly onto the backsheet.
