    This 100 watt panel has exceeded my expectations. The quality of construction is top notch. Wiring and cable connections are excellent. Great value for $80. Here are some quick lessons learned on how to maximize your power production with this panel:1. Be aware that there are 72 cells on the panel (4 across and 18 down). If even ONE of those 72 cells has a shadow or leaf on it you will cut your total power output by 50%. I repeat that if one cell out of the 72 has a shadow on it you are severely limiting your output. For optimal power output of continuous 6 amps you need to have full sunlight hitting all 72 cells (rectangles).2. I can routinely get steady 4-6 amps of power from this panel for 10 hours a day in bright sun.3. My best decision was to mount this panel on a lightweight and mobile frame that I can move left or right and up and down to manually track the sun during the day. I have the panel on my patio in full sun from 8 am until 6 pm. My panel is facing southeast at 8 am, rotated about 40 degrees facing south at 11 am and rotated another 40 degrees facing southwest at about 3 pm. This simple manual tracking system TRIPLES my daily electrical output to my battery compared to a fixed and immovable installation.4. The panel will produce small amounts of power (1 to 2 amps) even on overcast cloudy days.5. I use this panel to keep my 100ah deep cycle battery charged and when using my 2000 watt inverter I can run (one at a time) all my power tools, 1000 watt microwave, 1400 watt vacuum cleaner, 900 watt coffee pot, operate LED lights, charge my phones, etc. The key to success is only using these items during the day (except the lights) when the panel is simultaneously charging the battery. I can even run a 5000 BTU air conditioner or a 750 watt space heater for about 2 hours before it starts to wear down my battery. I always keep an eye on my charge controller when using high drain devices to make sure my battery never gets drained more than 50%. This panel can always “top off” my battery to 100% before sunset each day.Solar power is great, but it requires constant supervision for success. This is a very good panel.

    I bought these panels for my son to put on his work shop I was disappointed that the panels didn’t come with the installation hardware…so UL need to buy ur own brackets…

    Bought four of these panels for a small home system. Very high quality, not at all like “Chinese” past issues. I’m in the PV business and noted that the cells are perfectly in line, solder joints perfect and the lamination has no bubbles or other defects. The junction box on the back is just fine as are the cables. The cells are supposed to be Polycrystalline not Mono but they are not “sparkly” like Kyocera’s or other Poly cells. They are a deep blue-black and frankly, appear to be Mono’s. Haven’t seen cells like this before. The “fingers” are very tiny with no signs of silver ink sputtering. It appears that the cells for these 100 watt panels are “half” cells, cut from a much larger single cell. (Tiny “ears” on one end of the cell, flat on the other end).Very pleased with these panels. Hate to see the Chinese building panels this good after all the money poured into our own U.S. PV industry over the years but China is where the semi-conductors are made, so that’s where the silicon is too.

    Im from Puerto Rico and we’ve been in a power shutdown for 60 days at the day of this review. I bought two panels to charge a marine baterry to use a 40watts TV and 100watts fan. I got to say that it has delivered better than expected based on price and benefit ratio. Thanks to these I have decided to go full solar, BUT, My advise is that if you want to build a big system, It is better to go with 250watts panels to simplifiy and save space.

    I purchase two of these to add to two Renogy panels I have already but Renogy prices change every day on here from $110 to $140 so I thought I would give these a try. So far they give me more power at 17-19 volts compared to 14-16 volts and 6amps compared to 4.5amps. I’m feeling good about these panels so far! They are a little larger and build is about the same.I’ll report back and update if I have any issues.They are polycrystalline so they work best when pointing directly towards the sun but I just have them mounted flat on roof of my rv and they preform very well especially at noon :)Update: I purchased 2 more for a total of 600 watts of solar for my rv. Very happy with them.Would recommend.

    I combined multiple panels to decrease charge time on a bank of three batteries powering a 2000w inverter. The system powers a small chest freezer and the refrigerator in my camper. My campsite is heavily shaded so the generator is still required a couple of hours a day to power a battery charger but a couple hours is far better than the 8 or so needed last season.

    I have been doing solar since the 1990’s. I am upgrading my 60 watt panel for a small backup system I have at home and chose this one. I checked the voltage and amperage ratings of the panel I received, and both are within advertised levels. This is also a well-made panel. It comes with connectors and blocking diodes. The silicon used almost looks like monocrystalline, which is a real cosmetic bonus. I can’t comment on water resistance as it hasn’t been installed very long. However, for under $80, you can’t go wrong. Highly recommend this panel and seller who shipped it quickly and packed the item well.

    I now have 6 of these wired in pairs in series making 36v, then wired together in parallel. Connected to a epever Triron 3210n 30 amp charge controller. System has been running for a month now with no flaws. I have seen a maximum wattage ratting of 105 watts per panel, and in really cloudy conditions about 20-35 watts per panel, Here in Michigan during the month of April. I have only had 1 day so far where they produced absolutely nothing. Excellent product for the price, would highly recommend to anyone who is looking to build there first, or small to medium scale solar array.

    When I got the solar panel, I naturally decided to open up the junction box to see what kind of diodes (Blocking or bypass, if so how many) were in the panel. The box was not held together by screws, but by plastic locking tabs that broke when I opened the box (it took a good deal of force). After getting the box open, I found that the panel has not one but TWO bypass diodes so that it can generate half power even if partially shaded. The diodes are quite large and look like they could easily take the panel’s short circuit current. After breaking the plastic tabs, the box holds together just fine with self-tapping screws (why couldn’t they have used screws in the first place?).As for power output, these solar panels seem like they will live up to their ratings.[EDIT] They did. Today, under full sun, I measured 104 watts AFTER the MPPT. These are legit 100 watt panels.There are several reviews saying that these panels only put out 63 watts. That’s what you’ll get if you’re running them off 12 volts with no MPPT. If you want the full 100+ watts you MUST use a MPPT.

    These are an excellent value for the money, at only one dollar per watt you can’t do much better than these for the price. I’ve mounted two of these on the rooftop of my shed to power some 12 V lights. With a bank of 2 12 V deep cycle marine batteries wired in series and these panels wired in parallel to an MPPT charge controller these two panels charge the batteries enough to use 200 W of LED lights for Approximately six hours per night. I’ll post an update in a few weeks to let everyone know how these panels are holding up. Bless.
