3 Solar-tite 384 Silicone Elastomer Solar Cell Encapsulant Encapsulation Kits
May 22nd, 2012 | 
Author: 
This is one of the TOP most popular methods to encapsulate solar cells/panels!SOLAR-TITE 384 is one of the best solar cell encapsulants on the market. It was designed to better match the physical properties of the solar cells. Solar cells will expand and contract with changing temperatures. If you use the wrong type of encapsulation, micro-cracks in the solar cells will grow over time.Why are micro-cracks bad for solar cell efficiency?Micro-cracks form recombination centers for the charge carriers in the solar cell. This means that more of the suns energy is converted to heat instead of the more useful electrical energy. Additionally, micro-cracks change the thermo-physical properties of the solar cells.For encapsulants like EVA film, this presents serious problems. Even the smallest micro-crack present in the solar cell can grow rapidly in solar panels that were encapsulated with EVA film because the micro-cracks change the thermo-physical properties of the solar cells. The EVA film thus cannot keep up with the expansion-contraction of solar cells that are placed under the weather in the solar panels. This generates even more micro-cracks which change even more the thermo-physical properties of the solar cells.The effect of this is to reduce the efficiency of your solar panels. Your panels will degrade progressively and will eventually become useless. Every single “cheap” solar panel that is being sold on the market today (less than $2.5 per watt) fall under this category.The benefits of SOLAR-TITE:Encapsulating with SOLAR-TITE solves this problem. In addition to other helpful physical properties, SOLAR-TITE combines much lower viscosity with excellent adhesive properties which is difficult to get with other encapsulants on the market today. These properties prevent the micro-cracks that are present in most solar cells from becoming larger and thus preserves the efficiency of the solar panel.Product Description: This kit contains SIX bottles: THREE Solar-Tite 384 silicone elastomer base and THREE Solar-Tite 384 silicone elastomer curing agent.Two-part, clear, 10:1, RT and heat cure, good strength, UL and Mil Spec, same as SYLGARD 184Compatibility : Ceramic, Plastics, Polyesters. Product Resistance : Oxidation, Ozone, Thermal, UV Resistance, Water Resistance Thermal Properties -> High Temperature Stable, Low Temperature Stable.Viscosity: ~700cpWorking time:~ 8 hoursTwo-parts: Silicone Elastomer Base, Silicone curing agentDIRECTIONS:Ideally one would have soldered the solar cells together. Alternatively, the tabbing wires would have been soldered to the front of the solar cells (i.e. The part that faces the sun).Mix the contents of the base (large jar) and the curing agent (small bottle). Mix thoroughly. SOLAR-TITE is of low viscosity which helps in the escape of bubbles. Although vibrating the mixture will be helpful, in most cases it is not necessary. Most of our customers report excellent results without vibration of the mixture.2 possible methods of making the solar panel:One way to make the solar panel is to lay the solar cells into the frame and pour the mixture along the spaces between the solar cells. SOLAR-TITE provides enough working time (8 hours) for all the bubbles to escape before the mixture starts setting.Alternatively one can first solder tabbing wire only to the front of the solar cells. Then using a brush, apply a layer of the mixture to the glass and then place the solar cells on top of the application one by one in the required arrangement, making sure to keep the dangling tabbing wire bent up from the glass so that the arrangement of solar cells can be soldered together after the encapsulant hardens. Some have found that this method is much easier and also conserves encapsulant.After the encapsulant has set, one can now apply the backing material. A good backing material is our SOLAR-TITE 7741-TE, which was designed to have good thermal conduction properties as well as strong adhesive properties with SOLAR-TITE 384 as well as most solar cell encapsulants on the market today. Ideally, if one uses method 2 (see above) to make the solar panel, then SOLAR-TITE 7741-TE is a much more attractive option for the solar panel backing given that only a fraction of the SOLAR-TITE 384 will be needed for a given size panel. See documentation for SOLAR-TITE 7741-TE for directions for usage.

Schneider (xantrex) C40, 12/24/48v Charge Controller
The Xantrex C-40 controllers
can be used as PV charge controllers, DC load controllers or DC
diversion regulators in 12-, 24- and 48-volt systems (only the C-40 can
be used in 48-volt systems). They operate in only one mode at a time, so
two controllers must be used to provide both PV charge controller and
low battery load disconnect. As DC load controllers they disconnect the
load at a user-settable low voltage and reconnect at a higher voltage
reconnect point. As diversion controllers they send excess power to a
"dummy load" (such as a water or space heater) to regulate hydroelectric
or wind generators. When used in diversion mode, derate the amperage by
25%. All Xantrex controllers, when used as a charge controller, have
field-adjustable bulk and float set points and perform automatic
equalization every 30 days or whenever LVD is reached. Equalization can
be manually initiated with automatic shut-off. Order the optional
temperature sensor for a more accurate battery charge controller. The
optional LCD digital display shows battery voltage, array amps and
watts, cumulative amp-hours and a separately resettable "trip" amp-hour
measurement. The digital display is available for mounting on the front
of the charge controller, or with a 50- or 100-foot cable for remote
mounting in a double-gang electrical box. UL Listed. 2-year warranty.
