The most popular solar panels that are really the nice ones to have. It seems as if panels are getting lighter making them easier to handle, warranty is nice and their staying power is better than ever. Those cloudy days and angle obstructions are getting to be less of a factor. All I can say is that it's time you can have a solar panel for your home.
I've found Amazon to be a good place to source panels or kits recently. A lot of sellers have excellent return policies and you can always check their feedback from previous customers. Also with Amazon Prime you can get panels and parts in 1 to 2 days free shipping a lot of times. That's perfect when on the road or in the middle of a project and need an extra panel or parts.

1. Renogy 100 Watts 12 Volts Monocrystalline Solar Starter Kit
Another thing to consider before buying, is to look at whether they deliver to your home. Watch Renogy 100w solar panel unboxing.
This solar kit comes with the tools necessary for a new system: a Renogy 100W 12V Monocrystalline Solar Panel, a 30A PWM Wanderer Charge Controller, a 20ft 10AWG MC4 Adaptor Kit, an 8ft 10AWG Tray Cable, and a set of Z-brackets. Start your solar adventure with a Renogy Starter Kit. Negative grounding controller ensures the broader off grid applications and safety, especially to be used on a vehicle which has battery negative on the chassis.
A little extra investment on the right charge controller will generate a much higher return and prevent system failure.

Working Great So Far!By: G. Snappon
I bought this kit for a teardrop trailer I built. I wanted something to charge a battery that would power LED reading lights, an LED dome light, LED porch lights (just occasionally; I don't leave them on), and also a couple of 12 volt sockets (cigarette lighter type) that I could use to charge my phone, Ipad, Kindle, and also power my portable DVD player - either to charge it's battery or run it when the player's battery is depleted.
I knew very little about solar installation but had enthusiasm and a willingness to try.
I mounted the panel flat on the roof of my teardrop. Would it generate enough power without being angled toward the sun? Read on.
I mounted the included charge controller on the interior wall of the trailer, requiring about a 2 foot run of cable. I bought a deep charge battery at my local Batteries Plus. I built a battery box (with vents) and mounted it on the trailer tongue. It took maybe 6 feet of wire from the controller to the battery. Then I ran a plus and minus back from the battery - the positive went to a fuse block on the wall below the controller; the negative went to a homemade "ground panel" - a bus where I could wire the negative leads from all the stuff.
The controller has lights to monitor its functioning. There's a flashing green light that means it is charging the battery. I was happy to find out that it starts flashing soon after the sun comes up and keeps flashing until the sun goes down. It kept flashing when it was overcast and the sun was about to go down. It seemed to provide plenty of power despite the fact that it wasn't angled towards the sun.
Since it's mounted permanently on top of the trailer it meant that the battery was being charged while I was driving from one campground to the next. If it was the kind of application where it gets put away between campsites and pulled out to angle towards the sun I think I would end up with less charging. So far I'm very happy with the choice to mount it permanently to the top.
I bought a volt meter which I'm going to wire into the system with an on-off switch so I can monitor the status. My trailer isn't fully completed however; I'm still finishing off details like this. That means I don't really know what's happening. The flashing lights are nice, but I'd be happier with numbers.
Take this review with a grain of salt. I'm certainly not an electrical engineer. I need to do more research into how to measure the effectiveness, output, etc. I also think maybe my power needs are so minimal that this panel is overkill. LED lights are awfully efficient! However, I thought the price of the kit was very reasonable and so far it has performed exactly as I hoped it would.
Perhaps after I have more experience and have monitored it more scientifically I can add more detail to this review. I hope this is somewhat helpful.

Superior Quality 100 Watt Solar PanelBy: eelacabon
I am a solar submersible well pump dealer/installer and just last week I ordered the 100 Watt HQST solar panel. When I received it i really felt and seen the top quality and make up of the panel.
I was surprised because the panel was at 112 dollars and I expected it to be cheaply made. Not this one, this panel I will use mounted on a tripod to charge my RV batteries while out in the field.
I will no longer need to trickle charge my battery using AC, I plan on leaving this panel outside all year round to keep my batteries fresh. I have no doubt that this solar panel will weather the elements nicely and without any problems.
Get it now, just don't buy them all because I will be ordering some more soon.

Solid Solar Panel, it delivers the power specs it advertises.By: Preppedon
I have bought and installed 16 of these 100W 12V Eco-Worthy panels from Amazon, 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
