SUNGOLDPOWER 200 Watt Solar Panel, 2PCS 100W Monocrystaline Solar Panels for 12V/24V System, High Efficiency Solar Module Grade A Solar Cell for RV, Boat, Marine, Rooftop and Off-Grid

I was pleasantly surprised to discover that these panels are packaged very well with an extra foam cut out inserted on the inside of the non-energy face or backside. They were shipped very well protected as a box inside another box with plenty of cardboard and foam protection = outstanding. The quality of the panels are tops and match the no longer in business "KOMAES" line almost exactly. I added an additional matching pair to my existing Komaes system and it worked out perfectly. They are what they are at a great price for 100 Watt Glass Monocrystaline Solar Panels no matter where you are in the solar panel trajectory build out. I'd recommend them for quality, price and performance.

First the damaged outside packaging worried me. The driver let me open the box to examine and to my surprise, the panels were in a separate packaging which were not damaged. They came at the end of the day so I could not test the panels in direct sunlight. The next morning, I hooked them up in direct sunlight and they slightly over performed by my meters results and according to the label. 19.1 to 22.8 on the open voltage and 100.2 to 107.3 on the watts osculating because of light passing clouds in between. So, for now they are a great buy for me.

The solar panels appear to working as advertised and were a great price. So, no complaints on the product itself. But, inside the package was a card that said to follow them on facebook and that you would either get a free gift or an extended warranty. I did that but then never received any response from them. So, I emailed them and then they told me that I needed to provide a product review with pictures to receive the extended warranty (with no options for a free product). I have been seeing this a lot lately on Amazon and am getting really frustrated by the deceptiveness of the companies. So, just wanted to let people know that the additional benefits require more than the company says on the card they provide in the package.

I bought these to add to an array of older (and no longer available) Renogy 100D panels. The dimensions of the panels including the thickness and metal thickness of the fame was very close. The overall quality also seemed similar to the Renogy. However the mounting holes were in different locations that might be a problem for some additions or replacements. Also, the electrical parameters of peak power voltage and current are pretty similar so that in my opinion these panels could be put into series or parallel configurations with the older Renogy units.My rating is only based on the compatibility with Renogy panels. I have not had an opportunity to test out the power or efficiency of these units.

They are packaged very well, plastic corner pieces extra foam. They put out 91 watts peak when tested individually. Which was most of the day. Bought 4 100 watt panels, have 2 series, then 2 paralleled to charge 2 li time lithium iron batteries. Over all I think they are very well built, good looking panels.

Gets as high as 69 watts input on my solar generator; damn good for a 60 watt panel.

Looks like corner of package was dropped on the corner and bent the frame on both panels, it ripped the metal slightly but hope the weather dosent ruin it now

they were to big and weighed to much. i ordered 4 but got 2. had to ship back. also took a long time to get them also and the boxes were messed up big time. i had to redo (tape) boxes do they could go back. the shop station also added tape as the boxes were messed up.
