Ive been using this panel for a little over a month now. I really like to use things in multiple situations and gauge its effectiveness; This panel is perfect for what I am using it for. I wanted something that was lightweight, easy to store and transport to supplement my mounted solar panels. I don’t always have the best options for parking in the sun, and the angle is never perfect with mounted panels.
What I really wanted was a panel I could easily and quickly setup in the best location to supplement my charging. I have been extremely pleased with this purchase. It really filled the niche I needed with my setup in my camper van, and I also found myself using it in a lot of other applications because it is very portable and light weight.
1. Very portable.
I really liked how its all self contained, the cables, adapters, all come in a zipper pouch, and I ended up using it to store my 20 ft cables as well, so when it is time to set it up, its really a “Grab and go ” situation. The handles are very nice, and they have magnetic clasps so the unit stays closed until its time to use it. I really liked this feature, because it kept it safe, and stopped anything from slipping inside the panel when I was storing it.
The feet are velcro secured and right on the unit, its really nice that they secure so well, and they are always right there to use. That is one of my favorite things about this panel is that its all ” Self contained ” I do not need to look for feet, cables, or anything, because its all right there.
2. Well made
The construction is very sturdy, I’ve been using it for right around a month at this point and it still feels and looks new to me. Its very easy to clean/keep clean, the material is strong. I really love the zippered pockets and velcro hold downs for the feet. It keeps it all “Tight” and very quick to store and grab when I want to use it.
3. Comes with cable and adapters
I really liked how it came with extra cable length, and adapters for any device you might want to charge. I have some older power stations and was really surprised to be able to just directly charge those. It really made it easy to work it into my solar setup. It saved me money too.
4. Great power
Its a 100watt panel and I felt the output was very nice. Being so portable, it was very easy to set it up in the best location for the area I was set up in. I used an extra 20 ft cable I had as well, so it is always optimal. This really was clutch for me as it kept me from always being “Just about” there to fully charged on all my stuff. It is really perfect for my application.
Overall, I love this panel. It is so thin and lightweight, it just fits in a little niche I had for it like a glove. I have not had a single issue with this unit, and I cant imagine being without it anymore really. Just being able to add that extra wattage with the perfect output to my setup sent it to total perfection. Its just so nice how it folds in half and protects itself. I would really give this a try if you want something, Portable, well built, and effective.
Something else to add. I have been just grabbing this single panel and a power station for car trips and even a short hike. I really love the portability of this VS my massive fixed panels.

At first glance, this Grecell 100W looks like a copycat of the Jackery SolarSaga 100 with its color scheme, folding design, and handles that close magnetically.
IN A NUTSHELL The Grecell 100W, like the Jackery Solarsaga 100, just folds in half and is held together by strong magnets, accented by a rigid, bright-orange carry handle across the top. Within the built-in carry pouch is a built-in MC4 connector cable ready to be plugged into a battery power station with an appropriate extension cable. On an overcast morning, it had achieved as much as 59W of output whereas the Jackery SolarSaga 100 got 53W. The differential was small, and so I tested it again on a clear, sunny day. The Grecell achieved 84W and the Jackery got 72W. That’s pretty good efficiency as most monocrystalline solar panels lose at least 25% due to power conversion. A built-in kickstand helps orient the panel at an optimal, 45 degree angle for maximum sun exposure, and a built-in pocket allows for cables to be stored. Note that this solar panel is NOT waterproof.
It should be kept out of the rain, but then again, if it is raining, the sun probably won’t be out. Multiple adapters are included and I tested connectivity with Jackery, Goal Zero, and an off-brand Rockpals battery power station. All three worked with this panel as expected. As long as the power station is able to accept the panel’s 20V of output, you are golden. I also connected it in parallel with the 18V Jackery SolarSaga 100, and that took the panels from 53W/58W to a combined output of 102W. You should almost NEVER connect multiple solar panels in sequence/a series — you should almost ALWAYS hook them up in Parallel with a Y-split or combiner cable. (Goal Zero has a 4x combiner cable to hook up to 4 solar panels).
Overall, the Grecell 100W solar panels are beautiful, sturdy, efficient, and portable and worked well with a variety of battery power station vendors and solar panels. Having the MC4 connector out of the box makes the Grecell compatible with an industry-standard connection, but some power stations may only accept APP (Anderson) connections — in that case, use the included MC4-to-APP adapter cable.
TIPS/NOTES – Panel lifespan: Panels generally die/become inefficient between 25-30 years — They may last longer, but would produce less energy – Solar panels work best outdoor under full sun exposure — Although the panels will work under the shade or behind windows, charging efficiency is greatly diminished — Panels will STILL charge under cloudy conditions. So, keep the panels out even if you do not see the sun — Operating temperature range: 14F to 149F (-10C to 65C) — ONLY the solar panels can (and should) be directly under the sun while charging a battery power station — Keep the power station in the shade to prevent overheating – ALL panels must be uncovered to generate a charge — Do not completely cover one or more panels or the charging will stop – To maintain solar efficiency, the panels should be kept clean — Remove dust with a soft brush and wipe with a damp (NOT wet) cloth — Any residue, such as tree sap, should be removed as soon as possible — Keep panel away from water that spray at greater than 60 degree angles — Keep panel away from low-pressure (or stronger) water jet spray — Do not submerge the panel under water — Panels will work longer if they are kept away from water altogether – Do NOT bend the panels more than 30 degrees or risk breaking them! – Keep the panels away from fires and heaters
CHARGING TIMES When using solar panels to charge battery power stations, the amount of energy the battery may accept could be throttled to prevent overcharging.
Example: Jackery Explorer 1000 slowed incoming wattage from 70-80W to about 50W once it reached 70% battery charge.
HOW MANY WATTS DOES A DEVICE USE? – Calc: Watts used by device = Voltage x Amperage – If a vacuum is 120V and 9.5A, it uses 1,140W
HOW LONG DOES IT TAKE TO SOLAR CHARGE A BATTERY POWER STATION? – Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75]) — In a perfect lab environment, solar panels charge at the indicated wattage (ie. 100W) — Expect to only receive 50-75% on a good, sunny day (ie. 50W – 75W), depending on environmental conditions, panel’s age, and component quality — Tip: Even if it is overcast, the panels will STILL collect solar energy. Keep charging! – Charging with a 100W solar panel — Jackery Explorer 500: As fast as 6.7 hours [500 Wh / (100W x 0.75)] — Jackery Explorer 1000: As fast as 13.3 hours [1000 Wh / (100W x 0.75)]
I bought the 200W Pro version in Nov 2022. Now after 6 months, the panels died on me. I have used this no more than 12 times. I have taken very good care of these panels, always put them inside when done charging my solar generator, and was impressed with their performance. I would get at most 150-160 watts which is pretty good for a 200 watt panel. However, now after 6 months, they just randomly died on me! Went to use it after setting up properly and was only able to get a reading of 0.45 VOLTS. Yes that’s correct, not even 1 volt output. I will now be attempting to contact Grecell to get a replacement.
Update 6/14/23: After contacting Grecell, they sent me a replacement panel after I shipped back the broken one. Had to pay myself for return shipping but the new one was shipped to me for free. I tested out the replacement and it works perfectly fine. The customer service was very helpful and responsive. A+ on customer service. I have revised my review from 1 star to 4. Thank you Grecell!

I live in Austin, Texas where, for some ridiculous reason, they can’t seem to keep our electricity on. Since neither the governor nor the city seem to be interested in preventing a recurrence, I decided to do something to prepare for the next time they will leave me without power for days on end. I purchased a rechargable generator and this panel to recharge it. I’ve put everything together to test it and be sure that I know how to use it before it’s necessary, and they work great together and are simple to use. Thank you, thank you, for providing for me where the government repeatedly fails.

初めてソーラーパネルを購入しました。
ポータブル電源の充電に使っています。晴れの日は屋上に置いて1日フルにつかっています。
２つのポータブル電源を充電していますが、1日で両方とも満充電出来ます。
耐水性はよく分かりません。耐久性は丈夫な作りで、長く使えると思います。
この値段でこのクオリティは、買いではないでしょうか。

・ポータブル電源「G-500(B09RB1PYVG)」とセットで利用中
GRECELL製のポータブル電源「G-500(B09RB1PYVG)」とセットで利用するために購入しました。
初めはソーラーパネルなんて必要ないかなと思っていましたが、1泊2日でキャンプを行ってみると結構電気を使ってしまう事に気付いて慌てて購入。
・MC4コネクタで充電が行える
汎用の「MC4コネクタ(最大18V/100W)」でポータブル電源側へ給電できるため、特に難しくはありませんでした。
・折りたたんで持ち運べる
キャンプ時に折りたたんで持ち運べるため、邪魔にならず太陽の当たる場所で充電できるのが楽でした。
オートキャンプ場の場合、車をテント近くまで持ってこられるため車の上で充電することも出来、目に見える位置でポータブルバッテリーに充電が行えたためセキュリティ的にも良かったと思います。
・女性の方でも持ち運びやすい軽さ
女性の方でも片手で十分持てる重量で、折りたたんで収納、持ち運びが行えるため気軽にキャンプに持っていけました。
・充電ケーブル類も仕舞っておける
充電ケーブル類もソーラーパネル内のポケットに入れておけるため無くさず持ち運べます。
以前他メーカーでケーブルを紛失してしまうという事があったため、この配慮は助かります。
・少し汚れても防水防塵で濡れタオルで拭ける
床に置いて充電したり、車の上に置いて充電することが多いためどうしても汚れが付いてしまいます。
しかし、防水防塵(IP66)と撥水コーティングのお陰で濡れタオルでさっと拭いてあげることで汚れを落としやすいため、汚れを気にせず使えます。

停電時などでも多少は電気が使えればと思い購入。
配線を別で準備し、コンディショナーを経由して古い車用バッテリーに充電もできたし、安定化電源から100Vの取り出しもできた。
100Wともともと大出力ではないパネルなので、実際の気象条件や安定化電源自体の電力消費を考えればそんなに自由に電化製品が使える訳では無いが、これで夏に停電になっても車のガソリンを消費せずともスマホが充電できるし、家庭用の扇風機くらいは使えそう。

先に購入したポータブル電源 NECESPOW 806.4WH を充電する目的で購入。
このソーラーパネル付属のケーブルが充実していそうですし、購入したポータブル電源以外でも使えそうに思えたので購入
受取後、接続を試みましたが、購入したポータブル電源の入力端子が一般的でなかった為、接続できず。
その後、接続できる変換コネクターを入手して、早速接続し充電開始、ソーラーパネルについているステーで向きを変えながら
充電した結果99%までは受電出来る事が分かりました。
その後は３時間位継続して充電して見ましたが、それ以上の充電は出来ず。ポータブル電源側の仕様かどうかは分かりません。
軽微ですが、IHクッキングヒーター、炊飯器等を買って、その動作を充電した電源で確認。
車に積んで、移動先で充電もできるし、料理用電源も確保できたしで満足です。
ポータブル電源に太陽光パネルから充電できるのは良いですね。
購入して満足しています。
