  • Lightweight & very portable solar panels that is great for harvesting clean energy!
Size: 200W PRO
The media could not be loaded. I do have a 100W solar panel from another brand that has worked great for me to date. I am so impressed by solar panels that I decided to get 200W panels that I can carry while camping or during road trips along with my power station. This product checks all the requirements I had & I would recommend these for harvesting clean solar energy on the go. These can be very useful for emergency needs as when during a blackout. Here is my take after trying this product: Pros: - Very functional product and it does the job that it is supposed to do to generate electricity from solar - 200W 12V/24V capacity is appropriate for most basic to intermediate needs during travel unless you plan to use higher energy equipment - Has multiple safety standards including over-charge protection, surge protection & short-circuit protection - Weather-resistant panels that are IP65 waterproof let you use these outdoors without any worry - Panel has MC-4 connector & 4 connectors (DC7909/8, XT60, Aviation Connector, Anderson) that should cover most of the port needs - Build quality is appreciable as I don't see any issue as of now - Overall the product looks very fancy and modern. Has a sleek aesthetic overall & very lightweight to carry around easily - It has magnetic closure while folding making it a breeze to fold these - Manual leaflet has detailed instructions & is clear and precise - 24 months long warranty provided by the manufacturer showing their confidence in the product - Comes well packed and there was no damage to the product Cons: - There is no USB output in the board of these panels like my older 100W panels have that can be used directly used to charge any USB-enabled device - These are definitely expensive but I see these as one-time investments that will pay out over a period of time - Each of the 4-panel surfaces has an individual kickstand at the back and opening all 4 together sometimes takes a good effort. I wish these had some mechanism to control all 4 kick-stands together ... show more

  • Excellent Option to other more expensive units!
Size: 100W
Although Amazon's delivery could be better as there was a nice divot in the box, the solar panel itself was in perfect condition. It is easy to setup and very intuitive. It comes with a number of different connectors and adapters so, it is versatile as well. In my informal testing, the solar panels were inputting roughly 50-55 watts on an admittedly overcast California day. I used it briefly prior to in bright sunny weather and got anywhere from 80-90 watts in. Excellent! The build quality is good and the tilt-back legs work fine. Personally, not a fan of the velcro keepers for the legs as I just get tired of the ripping flesh sound velcro makes. But, thats a personal thing, nothing against the Grecell itself. It is nice and slim and will easily fit in a tiny spot in the back of your car on your camp trip. All in all, this is a great deal for those of us who are budget minded and don't mind a relative newcomer to the market. As long as it works as advertised, I don't care about the label on the front. Only time will tell how these items will fair over the long haul. Lets hope it gives the big boys a run for their money! ... show more

  • Sturdy, excellent canvas protection, value
Size: 200W
I just ordered this 200 watt solar panel and received it a day earlier than expected. Sweet. I recently bought the amazing Grecell T-1000 power station to go with it so i thought I'd stick with the same brands to connect. This is one beefy, lightweight, rugged, well encased product. The pocket to hold the wires re a plus. The thick canvas snap straps will provide that extra durability. I like the instruction booklet, quick steps and to the point. The handles are very grippable. This purchase was definitely overdue. The customer service is known for being spectacular, two other people in my extended family have the whole Grecell set, Word of mouth is everything to me. Price point- Bingo, best deal. ... show more
