Do not try to pick up a cell by merely pinching one corner and lifting it like a potato chip.
One of the safest ways to pick up a cell is to gently slide it off the edge of a table into the palm of your
hand. Once the cell is in your palm, you can gently grasp it with your other hand by spanning across the
cell with your thumb and finger. Gently, ever so gently…
Gloves are provided in the kit, but using them is optional. They will prevent fingerprints on the cells, but
this is only a cosmetic issue that won’t significantly affect the panel’s power output. If you do choose to
use the gloves, your sense of touch is reduced and could result in mishandling and/or breakage of cells.
Step 7 — Preparing cells for Base Panel cavities 2,3,4,6,7,8,10,11, and 12 (refer to Figure 2)
The blocks of plywood serve two purposes. First, they prevented cell breakage during shipping and they
are now going to be used as solar cell “workbenches.” It’s critical that the platform on which you prepare
the cells is absolutely flat, firm, clean, and smooth. These “workbenches” fit the bill nicely.
The top of the cell is the “pretty” blue side with the small silver wires spread out horizontally across the
surface. The top side is “negative” and the bottom is “positive”—like a very, very flat flashlight battery.
You will notice during—and immediately after—the soldering process that the cell will “bow” or cup
upwards. This is normal. If the cell is incorrectly restrained by the tape, stress will build up and the cell
may break, especially when you try to remove the tape.

Soldering the tabbing wires to the cells is
the most delicate portion of the assembly
process. Move slowly and gently!
Carefully place the first cell face down on
the cell workbench. Using masking tape,
attach it as shown in Figure 14. Do not
burnish it to the cell too much, and do not
put tape anywhere else on the cell (like the
bad examples shown in Figure 15).
Only burnish the tape enough to hold the
cell in place. The tape is only used to
prevent the cell from sliding around during
the soldering process, and you want to be
able to remove it easily without risk of
breaking the cell
Incorrect tape holding methods. Incorrect taping will cause cells to break!
