2. Shipping

Shipping for our 175 watt grid tied solar panels are done via truck freight and panels come on a pallet to avoid damage to the panel and glass. To minimize the freight cost and due to packaging, there is a minimum order of two panels per purchase. All on grid panels are shipped from Fremont, California, and the typical cost of two pallets on a pallet to most places in the continental United States is about $160 by truck. Shipping to residential addresses is $25 more, and it is a common practice by trucking companies. As the number of panels increase to about 20 panels per pallet, the average shipping cost per panel goes down significantly, to around 20 dollars per panel, depending on how far you are from Fremont, California. Please call 1-510-498-8221 for a custom freight quote based on the number of panels you order and your zip code. Everbright Solar reserves the rights to make adjustments to the order if shipping charges are calculated incorrectly, even if it's our system setup's fault.

Product Description


These untabbed 3"x6" Evergreen Devens solar cells Do It Yourself DIY solar panel kit contains 36 string ribbon multi crystalline cells made by Evergreen Solar, the all American solar company that has the smallest carbon foot print - they waste the least silicon in making these cells.These newest cells have a little different look from the other cells are still being made in the largest quantity in Evergreen solar's German factory (The German factory uses all American technologies and equipments, and it's adding another new production line going live this year). The front of the solar cells looks similar to the traditional multicrystalline solar cells in that they show the borders and shapes of irregular crystal formation. In terms of output they may be slightly better, but in any volume production you are going to have cells with varying levels of power output. 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. In our listings, if we don't describe them as 'chipped', then they are considered to be category A cells, though in small number of cells, very very tiny defects or blemishes could exist but they don't affect power output. Our sorting team tries to do as good as a job possible to categorize the cells, and we are confident that they are the best cells available on eBay outside of Evergreen solar itself. Almost all of customers have been very happy with the solar cells that we shipped in large volume, although we must admit that in the eBay retail market there are some people who are just very very hard to please, no matter how much we bend over to help them. We stand by our products. If you think the solar cells don't meet your expectations, send them back within 7 days for a complete refund or replacement, because we understand that in large volume order processing, some mistakes do happen and the important thing is that we are willing to rectify them and we need to be given an opportunity to fix rare mistakes when they do happen. We will even pay for return shipping. From the enormous number of cells that we shipped this past couple of months, returns have been essentially negligible. We will keep rolling out new products and categories at great prices and those who mistreat us will be excluded from our new offers.

The following is a little more details regarding this kit: (cells, tabbing wires, bus wires, flux, solder)

I: Cells:

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

Cell Specifications: Average Power (Watts): 1.75 Wp Average Current (Amps): 3.5 Imax Average Voltage (Volts): 0.5 Vmax Thickness = 200 micron = 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: $10 value - 40 feet of tabbing wires that Evergreen Solar uses to connect the solar cells. Cut them into 6 inch sections to solder onto the bus bars on the cells.

III: Bus wires: $2.5 value - 5 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: Solder: $7-$9 value - a tube of solder to help you solder the tabbing wires and the bus wires together, or whenever you need extra solder.

Some useful information in making solar power:

How to make sense of the above numbers:

The basic and very important formula you need to know to make sense of solar cells is this: Power (P) = Current (I) Multiply by Voltage (V), or P=I*V Power's unit of measure is watt, Current's unit of measure is amp, Voltage's unit of measure is volt. So in our solar cell's specific example, if each solar cell is rated at 1.75 watts on average, and the voltage is 0.5, you do a little algebraic math, then to get the amps (I), since P=I*V, so I = P / V , therefore I (amps) = 1.75 watts divided by 0.5 volts = 3.5 amps.

It's important to understand the concepts of series connection and parallel connection when stringing these solar cells together to make a solar panel. Series connection of the cells increases voltage but not amperage; parallel connection of the cells increases amperage but not voltage. Series connection is when you connect the positive terminal of a cell with the negative terminal of the next cell. Parallel connection is when you connect the positive terminals of all cells in the set of cells with a tabbing wire and all the negative terminals of all cell in the same set. You can use a combination of series and parallel connections to get the right voltage and amperage for your solar panel.

The cell specifications above were given to us by the manufacturer as averages. Variations are possible. To make a 18 volts panel, for example, you connect 36 cells in series (36 cells times 0.5 volt each = 18 volts). And 36 * 1.75 (each cell in theory averages 1.75 watt) watt = 63 watts. The amps you will be getting is 63 watts divided by 18 volts = 3.5 amps.

Solar cells basics:

The front of the cells (blue side, aka Sunny side) has two thick white lines, called bus bars. They are the negative terminals of the cell. The back side, where the 6 square dots are, are positive terminals. Connect the tabbing wires from the bus bar of the first cell on one side to the three dots of on the back side of the next cell. That way you have a series connection. Repeat the process on the other side of the cells. In panel making you should connect all the tabbing wires on the front for all the cells first, then flip the cells over to solder the back side in a second step. Some solar cells such as SunPower cells have both positive and negative terminals at the back of the cells, but we don't have to worry about them. Most cells are negative on the front and positive on the back. The white color bus bars on front and the contact points on the back are made out of silver, and you should keep them intact. Apply solder on your them and the wires should bond.

Testing:

Make sure that you test the cells under strong sun light with the front of the cell facing the sun, at the same time connect your meters to the right terminals. If you are inside the building, make sure you shine your sun simulating lamps onto the front of the cell while testing. Place the solar cells on a metal plate, ideally made from copper. With a warm light (ie halogen lights) shining on the cell, put your positive lead from your multimeter on the plate, and the negative lead of your multimeter on the bus bar. Your multimeter will be set to typically check amps or voltage at one time.
