As we left the previous video on how to build a 100 watt solar panel now we're
going to continue by preparing the solar panel for the encapsulation the first
step we need to do is by placing the silicon on the edges of the glass
this will prevents the resin from spreading out of the panel
epoxy resin is one of the best ways to keep solar cells from a home made solar
panel away from moisture for a panel of this size you will need about 40 ounces
about three pounds or one kilogram is enough it's not cheap but it is the best
choice over the eva film to encapsulate a solar panel made at home to know where
to get this type of clear epoxy resin follow the links in video description
below and of course epoxy hardener here the blend should be two times the epoxy
resin for one hardener
and mix these two compounds in a plastic container and mix it slowly mainly to
avoid getting air into the mixture
after about two minutes mixing the resin with the hardener mix it again in
another container to obtain a faster and stronger curing finish this second
mixture must be made to obtain a perfect and well cured resin
now what we have to do is to pour the mixture on the back of the panel to do
this simply pour the EPOC see resin from top to bottom in a constant movement
and after 12 hours you will have an encapsulated solar panel
now is time to make the panel frame get three l-shaped aluminum profiles two
meters long and at least three millimeters thick you can also go with
wood it all depends on your budget and how much you want to spend with your
panel this part can be done at the beginning knowing the size of the glass
the panel frame can be made and then with the glass attached on the panel
frame with silicone proceed with the welding of the cells and the bass wires
until finally the encapsulation is made but always put the silicone in the edges
of the glass before doing the encapsulation now I'll leave you with
the images on how to make the frame for your panel measuring the length of each
side of the glass mark each profile with a marker leave at least two millimeters
of cutting edge
next to cut the profiles you can use a cutter holder with a 90 degrees angle
but it is best to use a miter saw
an angular ruler can also be used to check the cutting angle it is also
useful to keep the profiles in place during assembly
and the best thing to attach the glass and frame together as to use stainless
steel brackets and screws for this panel I use 12 brackets 8 to support the glass
and 4 to join the profiles position the brackets in place mark and drill the
holes and now join each frame together
as I mentioned earlier we can make the frame before starting putting things
together we can make the frame and attach the glass with silicone then
start soldiering the solar cells the bus wire and in the end with the
encapsulation so add the silicon to the inner base of each profile then attach
the glass to the frame next put the brackets in place add the junction box
and then the 100 watt solar panel it's finally concluded so now we assemble a
frame and the encapsulated panel together
and now we put the brackets in place but if you decided to add a back sheet like
this one on the back of your panel do it before making the holes of the frame and
then proceed by putting the brackets in place Here I am NOT using the back sheet
and the reason is for you to see how the back of a solar panel looks like
and now glue the junction box with the same silicon paste make a hole to pass
the pole wires and you have a solar panel in your hands and now watch this
next part to see the voltage and amperage test
thanks for watching and I'll see you there
