The original 100 Watt solar panels have a lighter frame and are therefore lighter in weight than the heavier framed Renogy 100 Watt panels that look and perform virtually the same. I used four of the lighter weight DOKIO 100 Watt panels to construct two pairs of panels that are piano hinged on one side. I attached a cam action sash lock (to hold them closed) and a carrying handle on the other side. I sealed each of the screw locations with Loctite PL Marine Fast Cure Adhesive Sealant to prevent moisture entry. I positioned the solar panel sides to the inside of the hinge configuration to protect them during transport and carry. These two hinged assemblies when opened and wired together provide a nominal 400 Watt solar panel array. Note - the following information applies to DOKIO's original 100 Watt solar panels, not the 150 Watt panels described here on Amazon. Depending on your charge controller, you can wire the four 100 Watt panels in parallel (high 23 Amps/low 22.5 Volts) or in series (high 90 Volts/low 5.75 Amps). Another alternative (depending on your charge controller limits) would be to wire each pair in series (45 Volts/5.75 Amps) and then wire the pairs in parallel (45 Volts/11.5 Amps). The higher volts and lower amps can use smaller wires (10-12 Ga.) to efficiently (and safely) transport the power from the solar panel array to the charge controller if the charge controller is rated to handle more than 45 volts or 90 volts respectively. Update January 31, 2019 - At Ricky's request I added some pictures. Keep in mind that solar panel Wattage ratings are calculated under PERFECT conditions (the PANEL at 77 degrees Fahrenheit [not the air around it], 100% clean air and the panel perfectly aligned to the sun's rays). Virtually all solar panels will produce only about 70-80% of the panel's rated wattage in hot summer temperatures (-5% per 18 degree increase in the PANEL's temperature over 77 degrees). On the other hand, they can typically produce MORE power than the panel's rated wattage on very cold and bright sunshine days (+5% per 18 degree decrease in the PANEL's temperature below 77 degrees) so make sure your charge controller can handle the higher power if you plan to use these under very cold conditions. I discovered that I also need to work on controlling the RFI caused by the combination of my Chinese Manufactured MPPT charge controller and a 600 Watt Inverter ... RFI is not a good thing for operating Amateur radio equipment. Update March 23, 2019 - I have replaced my extremely RFI-Noisey Chinese Manufactured MPPT Charge Controller with a Morningstar PWM SunSaver Model SS-20L-12V that is compliant with FCC Part 15 rules regarding RFI control (made in Taiwan). Another Ham reported that this Morningstar PWM solar charge controller does not produce any RFI on his HAM system where he has connected his radio directly to the "Load" terminals on this model. Unlike most other solar charge controllers that allow only low-power lighting to be connected to their load terminals, this Morningstar charge controller's instructions describe full capacity loads (20 Amps in this case) can be connected to the charge controller's load terminals. This controller also includes a Low Voltage Disconnect (LVD) circuit that will shut the load terminals off if the battery's voltage drops enough to damage the battery if it is discharged any more. I will not operate my RFI-noisy DC-to-AC Inverter during Field Day. The FCC Part 15 rule compliant inverters cost in the neighborhood of $1,500-$2,000 and that high cost puts them beyond my budget. I haven't finished my portable power station for Field Day at this point but I will update this post after I get it operational and can determine if the charge controller produces any RFI on my Kenwood TS-2000 radio. Update June 27, 2019 - I updated my Field Day SLA AGM battery bank to a pair of Bioenno Power 12V, 20Ah Lithium Iron Phosphate (LiFePO4) Batteries and used only one of my 200 Watt panel arrays. The Morningstar Charge Controller mentioned above is designed to be used on Sealed Lead Acid (SLA), AGM or Flooded Lead Acid type batteries and does not work with Lithium batteries. To charge my new Lithium batteries I purchased a Genasun GV-10-Li-14.2V, 10.5 Amp 12 Volt MPPT Solar Charge Controller. I was concerned that its 10.5 Amp current limit might not handle the two DOKIO 100 Watt solar panels. However, in the 90 degree Fahrenheit heat (panels were hotter) and partly cloudy skies we had on Field Day this year, the panels (wired in parallel) averaged about 7 total Amps so no problem. I also used my older Kenwood TS-440SAT HF radio on Field Day and it worked very well. The Genasun Charge Controller (like the Morningstar) did not produce any RFI on the radio at all! We operated the TS-440SAT HF radio all day on Saturday on one battery and only changed over to the second battery around 9:00 PM and used that second battery Saturday evening until ~1:45 AM on Sunday morning when we shut down to get some sleep. We re-started at 7:30 AM Sunday morning and continued using the second 20aH Lithium battery until we shut down at the end of Field Day. The DOKIO solar panels did a good job on Saturday in spite of the 50% clouds (and a 20-minute rain shower). Sunday was mostly cloudy which limited the power from the two 100 Watt cells to about .12 Amps. Overall these solar panel's light weight and performance worked very well to build my small portable solar power system.

This $270 solar panel has replaced my $500 gas generator when I camp. Using the gas generator costs me about $30 a day in gas. This solar panel will have paid for itself in 9 days!!! No more smelly, expensive and noisy generator interrupting nature and my camp!! No more getting up at 2AM because the generator is out of gas. Lying flat, it produces 10-13 amps an hour for at least 6 hours per day, plenty for a small camper. Plenty more electric is produced throughout the days hours as well. Easy to use, being my first large solar panel, I was worried about correct installation. From opening the packaging to hooking it up to the charge controller took me about 10 minutes. One last benefit- it is large enough to cover a substantial part of my camper roof and it gives me shade and a cooler camper. Easy, cheap, powerful solar panel!!!

I’m giving it a 4 star because of the shipping and delivery people that they utilize. I ordered 2 panels and decided to get an additional pair a couple day later. The first set arrived and were in awesome shape the second set arrived a couple days later with a different shipping company. They were shattered. I did receive a refund and reordered still yet a 3rd set. They weren’t even taken off the truck and the driver noticed that they were also shattered! I will be trying a 4th time. The original set I received are in excellent shape and functioning as they should.

Fantastic panel came carefully packed and delivered. It's light enough for me to maneuver around without help. In few minutes plugged into my ecoflow delta and the watts start pouring in. Will have to do some experimenting to get most out of it but extremely impressed so far. I fooled around with wiring up arrays of smaller panels but should have immediately gone for the full size one right off the bat. Thanks amazon!

This solar panel has become a nightmare. I have it under direct Arizona sun and I'm only getting 150w instead of 400. This thing is huge and it was pain setting up, now I have to bring down again and schedule amazon to have it picked up. What a waste of time.

I ordered 2 sets of 2 panels each. Order arrived within 1 week, drivers carefully unloaded 2 boxes onto their cart and wheeled into my garage. One of the four panels (coincidentally the one at the very bottom, as they layed them flat) was all broken. I contacted the seller, and they have an outstanding service, so they sent me a replacement panel for free. It arrived in 3 days. Pros: Size is slightly smaller than 4x6ft but only by a couple of inches, makes the panel movable by one tall person; Pretty solid, but my suggestion - don't try to bend, and handle with care + 2 people is better than 1; Voltage/power is about 80-90% of what is claimed, which is good and still a big value. Cables are long, very convenient. Cons: Don't order 2, they ship in one box and aren't wrapped as good as single ones. Single ones are packed better. Surface seems to be fragile, might not stand up to small hail. Might need to figure out how to cover these. Overall, well worth it!
