HB21 is proud to bring top-of-the-range SunPower solar cells to the portable solar market. These cells have one of the highest efficiencies on the market, are more durable and even produce power in low-light conditions.

This 195W panel is an easy plug-and-play with Ecoflow Power Stations or any RV solar system using the standard MC4 connectors.

Folding legs allow for easy positioning with the best orientation towards the sun. Once the sun is down, it folds into a carry case weighing just 4.8kg and can be easily stored away even in tight spaces.

Eyelets all around the panel make it easy to hang the panel on the side or secure it on the roof of your vehicle while stationary.

HB21 195w solar panel

Used this to charge my Ecoflow River 2 pro. Worked well & got around 180w going into the River. Very happy with it.

HB21 195W Portable Solar Panel

Great lightweight panel. On average pulling around 150W. In perfect conditions (right angle, full sun) can pull close to 195W. Able to charge my River 2 Pro in about 4-6 hours from 0%-100%. Very happy with the purchase.

Exactly what I needed

I had my heart set on a different panel but luckily because it was out of stock I looked closer and noticed the MASSIVE weight difference. I am so happy the stars aligned and I ended up with this panel. It's a great portable size and weight. My testing had it charge my Ecoflow Delta 2 from zero to 80% in 8 hours on a day where there was scattered cloud. It does exactly what I need it to do and in a form factor that beats plenty of other panels.

Hb21 195w Portable Solar Panel

I purchased this solar panel to pair with my Ecoflow River Pro.
The panel arrived a few days ago and naturally the first thing we did was to set it up and see how it went. Amazing! This panel is so cool. The input rate sat between 194 and 197. Then the clouds came in and we thought it was all over - but no, the input rate dropped to around 57-65 during full black cloud.
We have yet to test it out on a camping trip but at this point feel confident that it will all go well.
Very happy with this purchase.

Great solar panel!

Bought this for my River Pro. They use the Sunpower solar cells which give me way more watts then my old 200W panel ever did. So light and portable as well.
