Who Portable Solar Is For
Portable solar panels appeal to owners who want extra power without committing to a permanent install.
A portable solar panel is often called a solar suitcase or a portable RV solar kit. It makes power at your campsite without cutting into your roof.
Your camping pattern settles this before wattage enters the picture.
Full timers who move often lean toward roof mounted systems.
Weekend campers and seasonal users often do better with a kit they can pack away.
If you already know you want a roof kit, our wattage guides cover installation and sizing. Each is a starting point, broken down at 200 watts, 400 watts, 600 watts, and 800 watts.
When Portable Solar Beats a Roof Mounted System
Portable solar earns its keep when the rig stays put and someone is willing to walk the panel into better light.
It also suits renters, borrowed rigs, and anyone unwilling to put holes in a roof. A portable kit is easy to try first, and nothing is permanent if your camping style shifts.
A roof array earns its place once travel days outnumber settled ones, because it keeps charging while the wheels turn. Full timers also value waking to a charged bank, with no cables to run and no panels to carry.
Portable Kits
- No drilling and no roof work
- Angle it by hand to follow the sun
- Packs away, and resells if plans change
- Left outside, so theft and setup are real costs
Roof Mounted Systems
- Charges while you drive in daylight
- No daily setup and no cable through a window
- Nothing to stow away at all
- Fixed angle, and there is no undoing it
If you camp mostly in shade or move sites nightly, a roof mounted system saves the daily setup and takedown a portable kit needs. Our RV solar system sizing guide matches panel wattage to your real power use, whichever setup you land on.
Portable vs Roof Mounted RV Solar Compared
| Feature | Portable | Roof mounted |
|---|---|---|
| Setup time | Set up and packed away each use | Fitted once, then left alone |
| Sun tracking | Tilted and turned by the owner | Whatever angle the roof gives you |
| Security | Sits on the ground, easy to lift | Mounted on the roof, harder to remove |
| Storage space | Takes up space when folded | No storage needed once installed |
| Power while driving | Cannot charge while driving | Tops up the bank while underway |
| Best camping style | Short stays, parked in one place | Frequent moving, daily driving |
| Wattage in published listings | About 90 to 400 watts | About 200 to 800 watts and up |
| Installation | No holes in the roof | Roof drilling or a professional install |
What Is Inside an RV Solar Suitcase Kit
Based on published specs from portable kit makers, a solar suitcase folds two rigid panels into a case. Retailer listings describe a carry handle, and several models add a kickstand.
Kits commonly include a charge controller built into the case. That part controls what reaches your battery, so you do not buy it separately.
A cable runs from the kit to your battery bank through a port or a window. Cable length varies by kit, so check the listing before you plan where the panel will sit.
Some kits use alligator clips for a direct battery connection. Others use a plug and socket, listed as SAE or Anderson, for a tidier setup.
According to published portable kit listings, output runs from about 90 watts to about 400 watts per unit. Makers also sell expansion kits for owners who want to add a second panel.
The panels inside are almost always rigid rather than flexible. See the comparison of flexible and rigid panels for the reasoning behind that.
Sizing a Portable Solar Setup for Your RV
Work from your daily power use, not the wattage printed on the box.
A phone charger, a few LED lights, and a fan draw very little. A CPAP breathing machine or a small refrigerator draws far more.
As a rough starting point, light use sits in the 100 to 200 watt range. Heavier daily use often lands in the 200 to 400 watt range.
Sun position matters more with portable panels than with roof panels, because you angle a suitcase kit by hand rather than leaving it fixed. Retailer guidance describes shifting a portable panel through the day to keep it in direct sun.
For more precision than a range like this can offer, the full sizing guide includes a load calculator.
For what each wattage tier actually returns in a day, see portable RV solar panel sizes.
One panel does not make a working setup.
A complete kit ships the panel, the charge controller, and the cable already matched, which takes the component guesswork off your plate.

The Real Drawbacks of Portable Solar Panels
Four things push owners back toward a roof array, and none of them show up on a product page.
Theft
A portable panel sits outside the rig where anyone can pick it up, and that worry is the usual sticking point.
Many add a cable lock or bring the panel inside overnight at unfamiliar campsites.
Cable runs
The cable has to reach from wherever you place the panel to your battery bank, usually through a window or door left slightly open.
That gap also lets in bugs, dust, and cold air depending on the season.
Chasing the sun
Portable panels only earn their angle advantage if you move them as the sun crosses the sky.
Skip that and output drops, because a stationary panel drifts out of direct sun within a few hours.
Storage space
A folded suitcase kit still needs a dry spot inside the rig or in a basement bay when it is not in use.
Owners short on storage often find this the point that decides it.
How to Choose Between Portable and Roof Mounted Solar
Begin with your travel rhythm, not with a wattage target.
A portable kit is a reasonable starting point if the rig sits still for a few nights. It only works if a short daily routine does not bother you.
A roof mounted system is worth the installation effort for shaded sites and frequent travel days. See what that install actually involves in the installation guide before you decide.
A folding panel you can carry is a straightforward answer to cloudy stretches and unexpected demand. Once you are ready to shortlist, the guide to buying RV solar panels compares retailers and complete kits on whole system price.
If a Roof Kit Is the Answer
Each wattage guide covers what that size runs and which battery suits it. Use them as a starting point, then size against your own daily use.
See both setups side by side before you commit to either one.
A1 SolarStore stocks portable and roof mounted RV solar kits, and publishes specs alongside its listings. That makes it easier to match a kit to your camping style rather than guess at it.

Frequently Asked Questions
What is a solar suitcase for an RV?
A solar suitcase is a portable solar panel kit that folds in half like a case.
It usually has a built in charge controller and a carry handle.
You set it up outside your RV and run a cable to your battery bank.
How many watts do I need for a portable RV solar kit?
It follows your daily watt hours, which have little to do with how big the rig is.
Small electronics need far less than anything with a motor or a compressor.
Add up your own loads before you shortlist a kit. Size your system properly.
Can a portable solar panel run my RV air conditioner?
A standard portable solar kit is not sized for air conditioning.
Air conditioning needs a large battery bank and usually a generator or a campground power hookup as well.
Portable solar works best for lights, device charging, water pumps, and small electronics.
Is a portable solar panel safe from theft at a campsite?
Anything left on the ground is easier to walk off with than a panel bolted to a roof.
Owners manage that with a lock, a site they can see from the door, or by stowing the kit at night.
Can I use a portable solar panel with a roof mounted system at the same time?
Yes, pairing the two is common, with the fixed array carrying the everyday load and the folding kit covering peaks.
Check your charge controller specs before combining panel types, since combined wattage needs to stay within its rated input.
Do portable solar panels work in the shade?
Output falls sharply in shade for portable and roof panels alike, since both rely on direct sun.
The one advantage a portable kit has is that you can park the rig in shade.
You can then carry the panel out to a sunny patch nearby.
How far can a portable solar panel sit from the RV?
That depends on the cable supplied, which the product listing spells out.
Longer runs are possible with thicker cable, though more power is lost over distance so the gain shrinks.
Are portable panels rigid or flexible?
Almost every solar suitcase uses two rigid framed panels hinged together, because the frame is what lets the kit stand on its own kickstand.
Flexible panels are a separate category aimed at curved roofs rather than portable use. Compare flexible against rigid.
