extending the life of the solar Panel.
- Made
of a soft silicon that absorbs impact, encapsulants provide a cocoon
around the cells preventing bugs, animals, and debris from contacting
the cells.
- Encapsulants extend the life of a solar cell by preventing oxygen and other gasses from oxidizing the cell during the normal function of producing power.
- Thermal expansion is often over looked. When cured, encapsulants are designed to set as a soft pliable rubber that will easily deform then return to its cured shape. (For example on a warm sunny day the temperature of a solar cell can vary 40 degrees with the passing of a cloud resulting in expansion and contraction of the cell.) The encapsulate acts as a shock absorber allowing the cells to expand and contract with little resistance hereby preventing breakage.
- Enhanced
performance is achieved through the encapsulants ability to bond the
cell directly to the glass providing all of its other functions and
allowing the cell to become one with the glass thus reducing solar
reflection and heat build up.
Qsil 216 has a 4 hour working life that can be extended by cooling below 65 and can be heat cured. Product normally cures in 24 to 48 hours. Qsil 216 is the most stable two part product on the market for the home builder.
This encapsulant does not have the problem of premature curing in high humidity.
Encapsulants are often compared to epoxy resins, and glues. There is no comparison. Solar cells float suspended in encapsulant allowing the cell to expand and contract with heat. Glues and epoxies are rigid and will cause your cells to micro crack and then fracture into hundreds of pieces as cells try to expand when subjected to sunlight.
Solar Encapsulant QSIL 216 is made of a liquid optic clear silicone that hardens to a consistency of jello tacky to the touch. The silicone is hardened using a Platinum based hardener when mixed in the proper ratio the hardener will set off a chemical reaction. Unlike epoxy you will not see a heat build up during cure. Encapsulants are designed to out last the useful life of your solar cells remaining clear and pliable for more then 20 years

Product Description
QSil 216 is a 2 part, clear liquid silicone which will cure at room temperature or at elevated temperatures.
This product is supplied in matched kits in a 10 to 1 ratio of A to B.
Mixing
Weigh 10 parts of A to 1 part of B. The mixing container should be 4 to 5 times
larger than the volume of silicone. Using clean tools thoroughly mix the A and B
components.
Storage and Shelf Life
QSil 216 should be stored in the original unopened container at 25C (77F). It will
remain useful for a period of 12 months if stored under those conditions.
