Product Description

110 pcs 3x6 Multicrystalline Solar Cells DIY Panel Kit

Product Details:

This set of 3"x6" (80mmX150mm) solar cells are string ribbon multi crystalline cells made by an industry leading solar company that has the smallest carbon foot print - they waste the least silicon in making these cells. The cells are the original factory standard cell size, not other sizes cut by using home made tools which could damage the cells during cutting process.

The cells have never been used or soldered, and are not recycled from badly made panels like some factory installed tabbed cells are. There are no tabs on these cells so you can start from scratch and get experience in making solar panels. The following is a little more details regarding this kit: (solar cells, tabbing wires, bus wires, and flux)

DIY KIT Technical Data:

I. Cells: 110 pieces plus some bonus solar cells

The standard cell specifications are the following, though the individual cells can be above or below these standards.

Cell Specifications:

Average Power (Watts): 1.75Wp
Average Current (Amps): 3.5 Imax
Average Voltage (Volts): 0.5 Vmax
Thickness 200ìm = 0.2 mm
Exact Dimension: 3 1/4 inches x 6 inches, or 80 mm by 150 mm
Weight: Just above 6 grams or 0.2 oz.

II: Tabbing wires: $8 value - 110 feet of tabbing wires to connect the solar cells. Cut them into 6 inch sections to solder onto the bus bars on the cells.

III: Bus wires: $6 value - 11 feet of bus wires. Use them to connect them between the series and connect the tabbing wires ends to the junction box at the back of the panel.

IV: Flux: $7-$9 value - an easy-to-use flux pen that dispenses flux onto the bus bar or your tabbing wires without leaving a mess. It's used to aid soldering and bonding of the wires to the cells. A must have item.

V: Diodes: $4.5 value - 3 diodes rated at 15 amp. Schottky style diodes.

108- 3x6 Untabbed Solar Cells DIY Solar Panel Kit w/Wire Flux Diodes Review

The material they provide is exactly as you see in the pic plus few extra cells for possible breaks in few. The item is exactly as described. However, I had difficulty soldering the cells together on the front side because the tip on my solder just was not the right type for it. You really need a flat screwdriver like tip on your solder and a minimum of 60 Watt iron. 45 Watt might work but it probably will be a bit slow to solder. If you do not have this, forget trying to put it together, as the tab wires are very stiff and requires perfect soldering setup.

Everbright's material is high quality, but it definitely takes the right setup to really put these DIY cells together. You have to have a nice flat large insulated surface, like wood or plastic, with right ventilation for soldering and steady hands with alot of patience, as you will be doing alot of it to put together 36-40 cells.

I decided that this was too much for me and decided to RMA. Mr Liu at Everbright was very nice and understood my situation and gave me a full refund even tho I messed with 3 of the cells and cut up some tab wires.

Very nice company to do business.

I would definitely buy from them again, but in the future, I will be looking for complete solar panel.
