Rated 5.0 out of 5.0 by Chance Even Better Than I Expected
I love this panel! I have set it up on a satellite stand and used the connections for aiming the old dish to tilt the panel for best power output.
I like that it has a very solid frame, not the cheap L shape frame. Very solid.
Well made with truly heavy duty connectors.

Rated 5.0 out of 5.0 by Benny 105-Watt Monocrystalline PV Solar Panel
Although this solar panel is advertised for boats and RV's for the most part, I purchased this for use at home, mounted on a pole in the back yard. I needed something with a smaller profile but with more wattage than the 45 watts offered by the Harbor Freight panels.

Rated 4.0 out of 5.0 by Conrad Happy with my purchase
I bought four of these for my camper so that I could boon dock for extended off-grid camping. These four panels were enough to cover my daily use on a sunny day. I found that these were not enough on a overcast day that was fairly bright, but estimated that they would if I had two more panels. So I bought two more and they can fully recharge my batteries on all but dark overcast and rainy days. I live in the Northeast and find that I need 1.5 Amp Hours of Battery Capacity for every watt of panel. You would need perhaps 1 Amp Hour per watt if you lived in the sunny western US.
My panels are mounted flat. I get about 5 amps out of them maximum so far. This is at the Spring Equinox with 12 hours of daylight. Perhaps if they were angled more towards the Sun, you could get the rated 8 amps.
The build quality is good. I did notice the panels were slightly different on my second order. I would have preferred that all the panels look identical. The diamond shape separators were smaller in the second batch. I used mounting brackets made by Renolgy that I purchased on Amazon. I was not happy with those. I recommend a mount that allows tilting.
If I could fit more of these on the roof of my camper I would. It is better to have too much power and not use it than not enough. A good charge controller will adjust the charging to match your batteries.

Rated 5.0 out of 5.0 by Solarguy Grape Solar 105 Watt PV Module
Well, this the second module I purchased, the first arrived with the glass shattered. Return and reorder was painless. Just went to local store. I have purchased 100 Watt modules from Grape Solar in the past, but they no longer make the ones I purchased. The 105 Watt module has slightly higher current output, but not enough that i can't place it in series with the 100 Watt modules. Quality seems good, comparable to other modules I have used. Says it is American made, but I suspect the cells are made in China. No instructions with it, but it is plug n play.

Rated 5.0 out of 5.0 by chayes6942 Fantastic Deal
Only 1 draw back to this panel is the power wires are too short. Luckily HD sells 12 guage lamp wife cheap. Used this panel on a 2 week "dry" camping trip. The first week it rained everyday most of the day and was overcast for most of the 2 weeks. We stayed inside the trailer a lot and used the lights almost constantly and our lantern broke so we had to use the outside too. We never started the generator one and our lights never got dimmer. This was the best investment I've made since buying the trailer.

Rated 5.0 out of 5.0 by OldSalt Great Product - Would have been nice to see a sample in the store before buying
Bought two panels to replace 15 year old ones on a sailboat. Panels are 36% smaller, put out 64% more power, and cost 50% of price paid for old ones. They are built well and have a good warranty. I called customer support and received good technical assistance and pleasant, prompt support. I had to purchase MC4 connectors separately (not sold through Home Depot). I looked up installation video for the connectors on U Tube and had no problem with installation.

Rated 4.0 out of 5.0 by Anon Best deal, need special connector
It may be the same for all solar panels but this one needs another MC4 cable as a recommended purchase (unless you want to just cut the MC4 connectors off the outputs of this for bare wire, but then one can't wire it in series with other panels as conveniently in future). So you can JUST BUY a single EXTENSION CABLE and CUT IN HALF for BARE ENDS. Otherwise it is hard to get a good connection since the metal is enclosed in the plastic MC4 connector.

Rated 4.0 out of 5.0 by sparky Works as advertised
Quality appears good. Voltage is as advertised. I will be ordering more of the panels soon. The installation paperwork verified the panels are for negative ground only. Had to research the panels at Grape Solar website to get more info. Mounted using EMT and conduit hangers for brackets which worked out great.
