Review: It's a Great Panel - WORKS Great
Review: Solid Solar Panel, it delivers the power specs it advertises. - I have bought and installed 16 of these 100W 12V Eco-Worthy panels from desertcart, to add to my original field of 4 100W 12Vpanels made by Ramsond (they were the cheaper panel a few years ago, Renogy & Eco-Worthy seems to have taken their market place recently) Each of these panels produced 5.5A+ and normally over 20V in full Florida sun, as measured on my multi-meter (I've uploaded photos with this review) I have my 20 panels wired in series, in groups of 4, running to my Outback Flexmax80 MPPT charger via two 10AWG runs, to my bank of Trojan Deep Cycle Batteries. These panels give me the expected VOC of 80+ (48V nominal) and at the sun's peak of the day I get the expected 27 amps of current. (MPPT charge controllers take the extra high voltage and converts it to charging current, if you're not familiar with the technology, check it out - super efficient) The only issue (really a non-issue for them) that I didn't catch is that the panel is slightly thinner than the Renogy or Ramsond, which made securing them to my rack just a little bit uneven next to the fatter older panels. Also, the corners on the panels look a little sloppily put together, a few are bowed/bulged out instead of having a neat seam, but this aesthetic doesn't appear to create a functional problem and certainly cannot be seen from the ground when roof mounted & producing energy - so it's not a big deal for me. The panels are, in my experience so far, worth the money ($140.00 currently) compared to other competitors in the market place. I've liked them enough from my first order to place a couple subsequent orders to get me where I am now at 2000watts (2.0 KW) As a quick ending note for any newbies - you have to realize that in the realm of solar a 100W label on a product rarely gets you a true 100W of power. Using an MPPT charge controller will help with squeezing out the potential wattage, but especially if using a standard charge controller you have to understand that wattage is figured based on Amps out x Voltage, and non mppt charge controllers use the batteries voltage to determine the charging voltage. For example a fully charged 12V battery will be average 12.8vdc so a charge controller will charge just slightly above that - say at 13.1V. So, figure 13.1V charging potential X 5.5amps (lets use 1 panel in full sun for simplicity) = 72watts of power from that panel. If using a MPPT charge controller, it takes the panels VOC, which in this case is about 20v x the same 5.5 amps = 110watts of power and is able to take all of the power from the panel it COULD produce and push more current into the battery than it otherwise would. So, conversely a discharged battery at say 11.8V (charging from a panel like this, in full sun) x 5.5amps = 64.9watts into the battery. Panels like these CAN produce their rated power in full sun and generally with the assistance of a mppt controller (because until your battery is darn near charged, you only get about 2/3 of your rated power production... and by then you don't need it as much because your battery is full!) I hope this helps anyone who may be mystified as to why their power production calculations aren't working out - usually it isn't the panel - it's the charging conditions including angle to the sun / time of year. Since going to MPPT, I've increased my solar harvest a lot... All after several years of head scratching. Happy harvesting folks! - David

## Questions & Answers

**Q: Can this item really produce 100watts or close to 100watts? What is the max charge this item can produce?**
A: In Full sun light it can produce 4-5 amps at about 18-20 volts.
Doing the math 4x18=72 watts.
I did measure under ideal conditions 20V and about 5A. Doing the math 5x20=100 watts.
But But realistically under most conditions the average out put on a give full Sun cloudless day it is more like
4A and 19 volts. 4x19=76watts.
 Every installation and location is efferent, but this is a rough theoretical estimation.
I fireguard on the slightly lower side as dust on the panels and in the air, haze and clouds (often there are high thin clouds 
that are not easily seen on a bright day).
 Also remember if you use a charge controller made for solar panels, like I do( Amazon has some $20 dollar ones for small arrays liket I use),
The controller will very the charging current as needed to charge the battery. 
So when you install the panels place them so you get the most Sun Light for the longest time in both summer and winter. 
 The angle of the Sun on the panel can vary greatly if the panel is mounted in a fixed position. This is the
easiest mounting method and the most common method. It is less expensive and low maintenance as there are no motors or 
moving parts.
Figure about a 20-23 degree angle  of the panel to the Sun as the earth is tilted about that much. This change through the year,
but is a good rough guide to start. You may want to do something
different at your location.
  I use two of them and charge two 146 amp hour deep cycle batteries and my panels are not tilted as I live in an apartment and cant mount them like I would like to do. 
On Sunny days the two panels can take two to four days to fully charge the
 TWO Batteries depending how much I use the during any given day.
 But remember my Installation the panels are in a sheltered place and NOT Tilted.
 So I think if the two panels were mounted like they need to be( As I suggested above) they would work better. 
  Hope this helps. As you can tell it is not a fixed answer as there are many thing that govern the output 
of the solar panel(s).

**Q: On Amazon this item is listed with two completely different dimensions. What is its actual size?**
A: hello, 47.6(Length) x 21.3(Width) x 1.2(Height) inch is the size for unpacked panel, and 55(L) x 23.3(W) x 1.4(H)  inch is packing size. Hope it will solve your problem. Thank you.

**Q: I'm looking for a solar panel with a female 12v adapter to charge a power pack i already own. Will this model work?**
A: With all solar panels you do not hook the panel directly to the battery you have to have a charge controller. I use mine every day to charge my jump box and batteries for my solar generator. Works very well. I do recommend opening the black box and making sure all you tabs are connected well, before installing.

**Q: Does anyone have a photo of the inside of the box on the back of the panel or know it they have terminals for using spade connectors and my own wire?**
A: Dear friend, could you please send a message to amazonzyh@163.com? So that we can send the photo to you.And yes, they have terminals for using spade connectors and your own wire. Thank you!
