A 300W foldable monocrystalline solar panel for larger charging needs, including home backup batteries, RV systems and off-grid living. An adjustable kickstand lets you set the best angle to the sun, and the foldable design keeps it manageable to store and carry.

Solar panels turn sunlight into usable power, so you can recharge without the grid. Pair the panel with a compatible battery, power station or device to keep your gear running wherever the sun reaches.

What to expect from the sun

On a clear day with about four hours of strong sunlight, a 300W panel typically yields roughly 900Wh of usable energy after real-world losses. Cloud, haze, shade and a poor angle will reduce that.

Good to know

A solar panel only produces power while it is in sunlight, and its rated wattage is what it can deliver under ideal conditions, so real-world output will usually be lower. Angle the panel toward the sun and keep it free of shade. Before you order, make sure the panel's connector and voltage are compatible with the power station or battery you plan to charge.

Setup and care

Unfold on a flat, stable surface angled toward the sun
Keep the panel clean and free of shade
Connect to a compatible device or controller before leaving it in the sun
Fold and store dry after use

Frequently asked questions

Does it work on cloudy days?
Yes, but at much lower output. Direct sun at a good angle gives the best results.

Will it work with my power station or battery?
It depends on the connector and voltage. Send us your model before you order and we will confirm, or call 1-800-680-4080.

How should I store and clean it?
Fold it, keep it dry and wipe the surface with a soft damp cloth. Do not use abrasive cleaners.

Can I leave it outside?
Use it outdoors while the sun is out, but bring it in during storms and store it dry for the best life.

WHAT THIS SOLAR PANEL IS FOR

300W with a kickstand: aim it at the sun without a mount

Panel angle is one of the biggest factors in how much power you actually get. This 300W foldable monocrystalline panel has an adjustable kickstand, so you can tilt it toward the sun without building a mount. It is sized for home-backup batteries, RV and off-grid setups, and for pairing with higher-capacity power stations.

Right for you if…

You want to recharge a larger power station in one or two sunny days
You want an adjustable angle without a mount
You live off-grid or RV full-time

Look at something else if…

You want something small enough to backpack
You need a permanent installation

What one clear day of sun gives you

A 300W panel with about four hours of strong sun typically yields roughly 900Wh after real-world losses.

Laptop (about 60W)about 15.0 hours
Small fan (about 40W)about 22.5 hours
Wi-Fi router (about 20W)about 45.0 hours
Small fridge (about 60W while running)about 15.0 hours

Rough estimates using typical device wattages. Real results vary with the device, temperature, sunlight and battery age.

If you pair it with one of these power stations

Hours of strong sun to refill from empty, if the connector and solar input are compatible (about 75% of rated watts):

UDPOWER S1200 Portable Power Station, 1190Wh (1190Wh)about 5.3 hours

Good to know about this one

Re-aim the panel as the sun moves. Setting the kickstand angle again every couple of hours can noticeably increase the day's total output.

Plan before you need it

Solar works on the sun's schedule. Winter days are shorter and the sun sits lower, so panels produce less than in summer. If solar is part of your outage or off-grid plan, order the panels together with the battery or power station they will charge, and confirm the connector fits before the weather turns.
