A bit disappointed. I built my own 400 watt suitcase. It does better giving 322 watts when right next to the Renogy giving 278 watts. The issue is the Renogy are black and get very hot reducing capacity. I still keeping them they are lightweight and nice packaging for what they are. I do wish they had done better at its thermal, not not make it black.

The panel works well. I consistently get 325 watts and during peak sun and location I have gotten 400-425 watts. I would buy again.

I bot five of these panels and wired them together in series in a solar array to produce 12 amps at 200 volts to daily recharge my Jackery 5000 Plus with extra battery pack (10,000 watt hour capacity). It is working great! My office is now operating off grid entirely from the power of the sun! This has been such a fun project!

Was looking for solar panel with all the features. After finding Renogy, no need to look further. Renogy and their knowledgeable professionals will take good care of you.

box was all torn up I'm afraid of opening it

Setup is easy and they work great.

Works was gett8ng around 375 watts from fall sun in ca. Will buy another one

Excellent Customer Service and Outstanding Support

I would like to express my sincere gratitude to the entire Renogy team for their excellent customer service, professionalism, and dedication to resolving customer issues. Their response was efficient, helpful, and reassuring throughout the process. I truly appreciate the way they handled my situation and their commitment to finding a solution.

Thank you to the entire team for your patience, kindness, and outstanding support. I am very grateful for the way you treated me as a customer and for the effort you put into resolving my problem. Renogy has earned my appreciation and respect.

Great addition to our portable solar. Now we have 440 watts.

The support legs are WAY too short. They do not allow adequate adjustment to focus on the sun in all situations. They are primarily set to capture Sun that is HIGH in the sky. Up here in the North, that becomes a problem in the Winter.

There solution was to just find something to prop it up higher if I needed to. WHAT? I know shorter legs saves you a couple of bucks on each build, but that is insane for a portable solar device. They said if that was not good enough I had to pay the shipping back and a 4% restocking fee.

I plan on keeping the panels but your support design, quite frankly, sucks. It limits use to what YOU wanted it to be without concern for the end user... and your response fully reflects that.

This is a PORTABLE device. There will not always be something available to facilitate your lack of foresight.

Seems Renogy is off of my shopping list for the future now.

So far i have been using this for about a week and it is keeping my camper charged

They look like they are solidly built with good hinges, also put out about 20% more power than my existing 400w panel

I've only used it once so far but it worked great. I topped off two power stations in just a few hours. Looking forward to using it with my Airstream Camper.

Got everything set up and the unit did a great job of charging and maintaining our batteries.

Easy to deploy. Easy to store, dont take up too much room in my truck. Good power delivery.

Shipping package on the solar suitcase was pretty bad. Box was mostly open on one end and obviously resealed on the other end. The panel does not appear to be damaged but have not used it yet.

I like that the panel is relatively light, easy to set-up and connect. So far have not been able to generate 400w of solar. Has been in the 285-305w range. I hope after more testingin different conditions it will provide 400w.

Very good power output. Well over 75% of max power output obtained from two series connected 400W panels in late February, SoCal.

Delivery was quick and panels arrived in good condition.

The panels need to be handled, in particular unfolded, with care. There is the potential to create significant stresses on the two hinges that link each adja cent pair of panels.

Not suitable for use in moderately strong winds if panels are not laid down flat.

As long as the panels are handled properly and windy situations avoided when not lying flat they should have a long lifetime.

Very solid construction. It plugs in easily to my device and delivers good output. Shipping and delivery was easy to track and delivery was as expected.

Checked the open voltage and it was right on. Have not had the chance to check it while charging my Solar Generator yet, way to cold here for and old goat to be out in it. Panel looks great, as well as it's suitcase. Shipping was fast and no damage to the box.

I've been using these portable panels for a year and a half. They are cumbersome, which I expected of a 400 watt set. In good sun I see up to 300 watts of generation. I have 2 complaints: the lip on the bottom of the frame collects dirt, the carry bag is not sufficient to protect the faces of the panels. The panels are very sturdy. A strong wind gust caught the panels and sent them cartwheeling about 50 feet across the yard. The set survived with no broken frames or hinges, and no damage to the panels. They still produce between 200 and 300 watts.

Easy to plug in the 400 W solar suitcase keeps my battery charged 100% when Boondocking

Great panels with a good case. Fast shipping and product works as advertised. Just ordered more from Renogy!

I wish you would include a cable with your connectors to match the output cable from the panels. I had to cut of the connectors to make it work

It may be 400 watts, but even in direct sun during the meat of the day, the most I can get out of the panel is 325 watts. It is easy to setup . You can see the quality in the construction and materials. Make sure you purchase connecting wiring. It only comes with a short pig tail of wire.
