THIS KIT IS A GREAT WAY TO LEARN WHAT IT TAKES TO BUILD A SOLAR PANEL WITHOUT A LARGE INVESTMENT IN TIME OR MONEY!
What sets this kit apart is the instructions: We have spent many hours making a very detail CD Updated often from customer input. Also the amount of products included in the kit is more than most "kits" out on ebay.
Look at pictures 2 and 3, picture 2 shows cells cut from 2BB( buss bar) cells where the collector line is more centrally located, picture 3 show cells cut from 3BB( buss bar) cells where the collector line is more to one side. I use mostly 2BB cells, occasionally I use 3BB cells.
Some kits I see don't even have an amount of tabbing included to be able to finish tabbing all the cells. Before you buy do the math ( 2 x the length of the collector line times the amount of collector lines), you need that amount PER CELL.
This kit is perfect for the curious novice who wants to start building his/her own solar panels. We will set you up with all the materials and knowledge you need to get started. If at any time you do not understand something, you will have our e-mail address for free online help! This kit is Solar 101 (I wish I had that class in college!)
Our mission statement is for everyone to have fun building this panel and to give you the confidence and knowledge to build a solar panel out of even larger cells without getting in over your head and getting frustrated!
When complete, you will have a **30+ watt panel to be proud of!
more accurately .521 volts at 2.03 AMPS Factory tested under STC ( standard test conditions)
STC ... Solar Panel manufacturers use what is
called Standard Test Conditions (STC). This means they put the solar
panels in a flash tester in their factory that has been calibrated to
deliver the equivalent of 1000 watts per square meter of sunlight
intensity, hold a cell temperature of 25'C (77'F), and assume an airmass
of 1.5. This flash test gives them their STC ratings. Consider these as
you would EPA mileage ratings ... how many of you actually get the
mileage they post?
the math on these cells using STC is 36 (cells) X .521V = 18.756 V x 2.03 A = 38.08 watts. knowing the chances of achieving "test results" in real life I say 30 plus watts
No other solar item seller will tell you about STC but HEART OF THE SUN-SOLAR.
INTERNATIONAL BUYERS: We offer this item " free shipping to USA, that mean a portion of the cost is the USA shipping cost, for the international buyers you will get charged LESS then it actually cost to ship to you. And we pass on to you our discount from the post office as well.
Here is what's included in your kit (and why):
45, 3" X 3" Square, Solar Cells (Rated at 2 amps each)
These cell are easy to work with. We give you 45 cells because handling cells is tricky, and you will most likely break a few. No worries! You will only need 36 to complete our suggested panel.
25 feet of tabbing wire (22.5 is needed)
Flat, skinny wire used by professionals to connect cells together. You need 6 inches for each cell, so this gives you a bunch extra to experiment with.
48 inches of bus wire
Wider, thicker wire used as a common connection point for multiple connections. The more current flowing, the thicker the wire needed.
2 feet of 18 gauge black and red wire:
You will attach these wires in the junction box.
One blocking diode: 3 amp
A blocking diode is a semiconductor device used to stop the flow of current from one direction, but allow it in the opposite direction; a one way street sign for electricity. When the panel is making electricity, it will flow into your battery and charge it. However, if the sun goes behind a cloud, the charged battery would try to flow backwards into the panel, draining the battery and/or potentially damaging the cells. The blocking diode prevents this back-flow from the battery.
Keeps the glass front and the plastic back from putting unwanted pressure on the cells.
One Rosin Flux Pen
Helps adhesion and solder flow.
One tube of solder in a dispenser pack, 17 ft
This is leaded solder, which has a lower melting temperature and is easier to use (in my opinion) than the "No lead" type.
One basic Junction Box
Attaches to the back of the panel for connecting wires from inside and outside the panel.
INSTRUCTIONS! INSTRUCTIONS! INSTRUCTIONS!
(The instructions are contained on a CD, which saves paper and enhances the picture quality!)
* 3 videos, 32 pictures, and 35 pages of detailed step by step instructions!
* My e-mail address to ask any questions( seriously that email goes right to me)
* How to solder tabbing wire on your cells
* How to connect tabbed cells together
* Connecting strings of cells
* How to attach the plastic backing and junction box
* How to test your connected cells
* How to make a frame and attach the frame
it is all covered on the CD.
* A list of tools and supplies needed to complete the project
* A web site I found to have a wealth of FREE information
* The name of a great magazine that has so much information in it all geared for the home owner
You will need a soldering iron. I recommend a 40 watt most 20 and 30 watt irons just are not hot enough, the adjustable soldering iron stations are wonderful. I do sell these 40 watt soldering irons and the adjustable soldering iron stations in my store.
Soldering iron: 40 WATT is recommended, either the gun style or the stick kind, chisel tip (Not a pencil tip. However, I show how you can modify a pencil tip on the instructional cd)
Not absolutely necessary, but very helpful.
A VOLT METER( MULTI-METER)I do sell these multi-meters in my store.
Additional items you need for this project NOT included in this kit:
A tube of silicone (clear) [Hardware store]
A sheet of window glass use a piece 36" x 18" ( 46cm x 92 cm) [Hardware stores typically sell a pre-cut 36 x 18]
A sheet of plastic also 36” x 18” 1/4 inch thick ( .5 -.6 cm)
If you intend to charge a deep-cycle battery you will need a small charge controller. This will act like the diode and will give the battery electricity in the way the battery prefers. I do sell these charge controllers in my store.
TWO 8’ x 1/2" ( 2.44 M x 13mm) aluminum c-channel for frame.[Hardware store]
Two very useful electrical current and wattage equations are:
I: Current (in Amps), V: Voltage (in Volts), P: Power (in watts)
Watt's Law (I*V=P)
So our equation for this panel is: I tend to use even rounded Down numbers
36(cells) *0.5 volts each) =18(Volts Total)* using Watt's Law: I * 18V = 36 WATTS
More accurately the math on these cells using STC is 36 (cells) X .521V = 18.756 V x 2.03 A = 38.08 watts
*The reason It's a 18 volt panel is to charge a 12 volt battery. 12 Volt batteries rest at close to 14 volts fully charged and need more then 12 volts to charge fully. 18 volts is the Industry standard on best voltage to charge a 12 volt battery. Also 18 Volts is the normal because on many day your 18 volt panel may not be producing its full 18 volts it may be only producing 14-18 v depending on weather, angle to sun, time of year ETC. Always use a Charge Controller (CC) when charging 12 volt batteries with a s18 volt solar panel or you can damage the battery by overcharging.

You can go to my feedback and read all of these and more!
Some of the cells in the kit will have small chips on the edges; they are cut from larger cells and it is just part of the process due to their delicate nature.
Some of the pictures in the ad are of a completed panel. This is an example of a panel you will construct with the kit. Kits do no include a completed panel!
**THE CELLS ARE CUT FROM THE 6" X 6" CELLS I HAVE FOR SALE. THEY ARE RATED OVER 8 AMPS EACH. CELLS ARE RATED WITHOUT ANY COVERINGS. ONCE YOU PUT A GLASS FRONT ON YOUR PANEL, EXPECT A LITTLE LESS OUTPUT THAT IS WHY I SAY 30(watts)+ WITH A 36(watt) MAX.
