The best solar fan for sunroom duty has to earn its place in a room made of glass, where afternoon sun piles up heat and there is rarely an outlet where the air needs to move. We compared 5 solar fans on what their listings state: panel setup, speeds, battery capacity, weather protection and warranty terms. A dual-panel fan with a large battery leads the group, a two-fan kit with a stated protection code follows, and the rest cover portable, folding and lantern-style options.

Maraiss 22000mAh Dual-Panel Fan
A dual-panel solar fan with a 22000mAh battery, 5 speeds, a three-level LED lamp and a 20W USB power supply.
Pros
- Two monocrystalline solar panels instead of one
- 22000mAh battery with 4 to 20 hours of stated runtime
- Dual USB ports that act as a 20W emergency power supply
- 5 speeds with noise under 35dB at max speed stated
Cons
- Spec table lists a ceiling mount while the bullets describe a stand and swivel hook
- Recharge takes 4 to 8 hours depending on sunlight intensity
- Runtime range of 4 to 20 hours depends on the speed setting
- Yellow is the only color stated
Detailed Review
The listing states two monocrystalline solar panels, a 22000mAh battery, 5 speeds driven by a brushless motor, noise under 35dB at max speed, three LED lamp levels with 18 to 120 hours of lighting time, a 5-stage timer of 1, 2, 4, 6 and 8 hours, a 90-degree adjustable stand and a 360-degree swivel hook, plus dual USB ports that act as a 20W emergency power supply. Charging takes 4 to 8 hours depending on sunlight intensity, and runtime runs 4 to 20 hours depending on speed. One catch: the spec table lists a ceiling mount while the bullets describe a stand and a swivel hook for table-fan use, so trust the bullets. The maker states 1 year of professional support.
Who it's for: sunroom owners who want one unit that fans, lights and charges phones through an outage. Who should skip it: anyone who wants a stated weather protection code, which this listing does not give.

The fans mount together as exhaust or intake, one each way, or separately. The aluminum housing and double metal nets suit harsh outdoor use, and the maker states a 1-year replacement warranty for defects.

Yueidung 4-in-1 Camping Fan
A portable 4-in-1 fan with 4 speeds, a three-mode LED light strip, a timer and a compass, charged by sun or Type-C.
Pros
- 4 roles in one: fan, light strip, timer and compass
- Charges from solar or Type-C
- Three LED brightness levels for evening use
- Indoor and outdoor use stated
Cons
- No battery capacity is stated
- No warranty term is stated
- Spec table lists 1 by 1 by 1 inch dimensions, which cannot fit a fan
- 4 speeds is the fewest of the speed-stating picks
Detailed Review
The listing states a fan with 4 speeds, a brightness-adjustable LED light strip with three light modes, a timer function and a small compass, charged by solar or through Type-C. Indoor and outdoor use is stated, and the features list calls it foldable. The spec table gives dimensions of 1 by 1 by 1 inch, which cannot fit a portable fan, so treat that as a listing error.
Who it's for: readers who want a small grab-and-go fan with a light for evening hours in the sunroom. Who should skip it: anyone comparing battery capacity, since no figure is stated.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a sunroom fan, safety means stated weather protection codes and safety-relevant features; one of the 5 listings states a protection code, and the rest state none, so they score zero on that line. One of the 5 states a warranty term with a concrete period. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Maraiss 22000mAh Dual-Panel Fan | 9.6 | 30 | 21 | 21 | 0 | 3 |
| Yueidung 4-in-1 Camping Fan | 9.4 | 26 | 19 | 20 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best solar fan for sunroom use
Start with where the panel sits
Every fan here is solar powered, so the panel’s spot decides how much air you get. The Maraiss lists two monocrystalline panels, the JINLICTE lists a 7W panel, and the erifyng kit lists two 5-inch fans on a 13-foot cable, which gives you room to put the fans where the heat gathers. For glasshouse-style spaces, see our best solar fan for greenhouse guide as well.
Match speeds and noise to the room
The Maraiss lists 5 speeds with noise under 35dB at max speed, and the Yueidung lists 4 speeds with quiet operation. If the fan will sit near a reading chair, the 5-speed pick with a stated noise figure gives you more control over the sound. For nights at a campsite rather than a sunroom, our best solar fan for camping compares portable picks.
Decide how much evening airflow you need
A sunroom stays warm after sunset, so a battery changes what a fan can do. The table below shows what each listing states about battery capacity and runtime.
| Fan | Battery capacity stated | Runtime stated |
|---|---|---|
| Maraiss 22000mAh Dual-Panel Fan | 22000mAh | 4 to 20 hours |
| erifyng Solar Dual Fan Kit | Not stated | Not stated |
| Yueidung 4-in-1 Camping Fan | Not stated | Not stated |
| WESTTREE Solar Fan X98 | Not stated | Not stated |
| JINLICTE Solar Fan Lantern | Not stated | Not stated |
The Maraiss is the only pick with a battery figure and a runtime figure on the listing. The JINLICTE at least pairs its fan with an LED lantern for the dark hours. For a boat cabin that needs airflow on the water, see our best solar fan for boat.
Read the protection code and the warranty line
Only the erifyng kit states a weather protection code, IPX7 for its fans. Only the Maraiss states a warranty term, 1 year of professional support. The other three listings state neither, so buy them for the stated specs alone.
Sizing Notes
- Match the panel to the sun: the Maraiss lists dual monocrystalline panels, while the JINLICTE lists a 7W panel.
- Size the battery to the evening: the Maraiss states a 22000mAh battery with 4 to 20 hours of runtime depending on speed.
- Leave cable room: the erifyng kit lists a 13-foot cable between its two 5-inch fans.
- Check the warranty line before you mount: only the Maraiss states one here, 1 year of professional support.
