Renogy 220W Lightweight Portable Solar Suitcase, Foldable Solar Panel with Kickstands for RV, Camping, Blackout, Off Grid System

Love these panels!! Durable good quality and works great for my application. I have owned these for about a year now. They are great for camping trips, charging my Jackery and Bluetti. They are compact and easy to set up. My only complaint is the lead is short. Will purchase another set to have double the input.

Real world experience: I got 184w straight out of the gate, setting this up in the afternoon on a summer day in Seattle. After the panels warmed up in the sun, that dropped to between 170-175w for the next two hours while charging my Ecoflow Delta Mini. Had the same experience deployed while camping. About other reviews stating it performed poorly: Solar panels typically don't hit their stated maximum wattage outside of a lab. This is because 1) Panels need to be properly aligned to the sun, and 2) Efficiency of all solar panels decreases as they heat up. You're not going to see peak power output on hot days. *Also depends on the charge controller and battery setup it's connected to. Why this panel? I upgraded from a 100w Jackery, as it barely output enough to compensate for the draw from my fridge (~70w). I wanted to generate significantly more power without sacrificing much more room in the back of my car when camping. This suitcase fit the bill, as the form factor is only slightly larger and I'm getting >240% more power out of it. The 350w and 400w panels are all way too big for car camping. Why not the 200w Renogy folding panel (ASIN B0CNPHD4VY)? I opted to spend the extra ~$100 even though the output is nearly identical, because I wanted the warranty and durability that the rigid panels provide. There's no fabric on these to fray or breakdown, it's all metal and plastic, so I'm much more comfortable tossing it on gravel, dirt, grass, etc. *The leads from the panel are only about two feet long, so you'll need to source your own extension cables for your specific needs. I don't consider this a complaint as it's industry standard.

Solid 180 watts output, which is expected for a PV module in real-world conditions. (Standard test conditions for PV modules are different from real life. No matter the manufacturer, you'll end up getting 75%-85% rated output depending on temperature and solar insolation.) Easy to set up, as advertised. On a "typical" summer day you'll get about 1 kWh energy, so it pairs well with any portable battery inverter that has 1 - 1.5 kWh of battery capacity. I like the included nylon case with a large pocket to carry extension cables (not included). It's light enough to be easily portable, heavy enough to not blow away, and sturdy enough to last many years. This 220w Renogy panel would be perfect for the day-trip outing where a portable battery by itself might fall a bit short.

This Renogy 220w solar panel set is of great quality but the end result is ok , this set of panels have a true to lift output of about 85% to 90% of stated out put wattage I would think it could be at least 90% + on an all clear sunny day . Should be the standard for quality construction of these panel.

I purchased these solar panels to charge the lead acid battery on my Scamp trailer as well as a Goal Zero Yeti 700 Watt power station. They work well, even on cloudy days. On sunny days I get in the 180s in watts coming in and on cloudy days it can be low, 10-20 watts, but it trickles in and keeps my batteries topped off. For the Scamp battery, I also purchased a Victron MMPT 100/20 charge controller that is hooked up between the panels and the battery to modulate the energy coming in from the panels. For the Yeti, it has a built in charge controller so the panels can connect directly to the Yeti, with their cable. I also purchased extention cables so that I can move the panels around camp to follow the sun. They have worked well for my situation. Recommend.
