Overall, this is a good starter kit. The build quality is good, the panels are good, the charger is good, the cables are ok, the case is great. If you want something relatively simple and straightforward, this is probably your best bet within this power range. The while assembly is heavy, but well built. The panel, frames, swing out controller bracket, and adjustable legs are all pretty good. I feel the legs and the adjustment supports are too short. They could have made them each 3-4 inches longer, and that would have been perfect for the angles you need throughout the day. Its not a big con, but just saying they could have designed longer legs and brackets for minimal cost and afforded you more adjustment range to dial this thing in better. The controller bracket swings out, and has a velcro backing to keep it tucked if you want. Overall, the assembly sits very solid, and feels solid when closed up. The latches are pretty cheap, and I had to massage them a bit to finish the installation of the loops. The carry handle feels solid. The carrying case is fantastic, and well beyond expectations. The PV panels themselves seem like good quality, and yield great power output for their rated capacity. A lot of the CCJ non-rigid, super compact, folding panels mounted on sort of a cloth or fiberglass material you will see on Amazon are rated for, say, 120W, but in reality they are more like 90W rating. These Renogy panels deliver a pretty reliably 75% of their rated capacity with the included PWM controller. Those other panels deliver more like 50-55%% of their rated capacity with a PWM or 65-70% with a (far more expensive) MPPT. So, don't let the lowly 100W rating of these fool you. The included PWM controller is nothing to write home about, but far better than you get in the typical CCJ non-rigid, super compact, folding kits. I can get a pretty consistent 155-165W of power being delivered to batteries from two 100W panels through the included PWM controller in a little less then perfectly optimal conditions. I have seen short peaks (30 seconds or less) of up to about 180W delivered to batteries with peak sun, peak angle, and low charge state on batteries. Basic info is available, V, A, Ah, SOC lights, and other status lights. Can be set for a variety of battery types. Simple, easy, straightforward. Does not include USB charging ports or a load output, which may be a con for some. The cables are mostly just ok. The ones coming out of the panels are a bit too small AWG, IMHO. Wished they were more like 12AWG. The pigtail for panel power on the controller is too small AWG. That should have been at least 12AWG and preferably 10AWG for situations were you may connect several panels to the controller up to its rating. Same on the pigtail for battery power. That should have been at least 12AWG and preferably 10AWG, again, for situations where you use multiple panels up to the controllers rating. The battery cable is too small AWG. That should have been 12AWG and preferably 10AWG. Its a 20A controller, and all the cables should have been rating for that at the minimum. Even better with 10AWG to reduce Voltage drops as you add length, which you pretty much will have to do in most cases for this product segment. Its fine, the included set up will work up to a point. Plan on buying a few cables, in-line fuses, etc., to have a complete, proper set up later as you grow the system. With two 100W panels and the included controller, a sustained 12A current flow to battery occurs often and for extended periods. I have seen it peak as high as 13.7A for short periods (30 seconds or less). In summary, this is a good kit for a good price. This is aimed at the segment who will always have a battery (or power station, Jackery, etc.) and then power loads from it, as opposed to powering things directly from the solar kit. Great for RV-er's, emergency storm duty in a residential setting (with batteries), etc. The included 20A controller rating does afford you some expandability. You for sure can add a second 100W panel in parallel (manual says series configuration limit of 25VDC, so you cannot do two of these panels in series). A third 100W panel in parallel could also work, but you should probably look to get a 30A controller and increase the AWG on some of the cables.. You might exceed 20A in and out of this controller with three 100W Renogy panels for short periods in peak sun and hungry batteries. Minus 1 star for the undersized cables.
