Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a skylight, safety means UV protection and impact resistance the listing actually states; a dome that states neither scores zero on that line, whatever its size. The GEATaaT dome states a 2 year term and the ICON dome states a 1 year term, and the other picks state no warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| GEATaaT Clear Outer Dome | 9.6 | 30 | 21 | 21 | 5 | 3 |
| RVGUARD Smoke Bundle | 9.6 | 32 | 22 | 22 | 7 | 0 |

| XMK Inner Dome 14×22 | 9.4 | 26 | 20 | 20 | 3 | 0 |
Every total is translated into a figure between 9.2 and 9.8 with a linear formula; ranking by points and ranking by score always agree.
How to choose the best rv skylight
Measure the opening before you order
Every pick here fits a 14 x 22 inch opening, so that figure is the one to match first. Measure the opening in the roof, then compare it with the dome and flange figures: the GEATaaT and ICON domes carry an 18 x 26 inch flange, the Straight Creek bundle carries a 17 x 25 inch flange, and the XMK inner dome carries a 23.6 x 16 inch flange. A flange that runs past a vent or a roof seam will not sit flat, so measure the clear roof around the opening as well. Roof space is shared with panels on many rigs, so see our best 100 watt solar panel for RV guide before you claim the last clear patch for a dome.
Clear or smoke
Clear domes let in the most daylight, while smoke domes soften it. The RVGUARD bundle states 30% light transmission for its smoke outer dome and 88% for its inner dome, and the ICON dome uses a smoke tint for softened light. The GEATaaT and Straight Creek domes are clear, and the XMK inner dome has a clear window. Over a shower or a sleeping area, a smoke finish keeps the room calmer in bright sun, and the RVGUARD bundle is stated to reduce heat buildup. For the light inside the rig, see our best RV light bulbs guide.
Inner dome, outer dome, or both
An outer dome alone suits a roof where the inner garnish is still sound, while a bundle replaces the whole stack. The RVGUARD and Straight Creek bundles include both domes, and the Straight Creek bundle adds lap sealant. The GEATaaT and ICON picks are outer domes, and the XMK pick is an inner dome with a clear window. Match the pick to the part that failed, and order the other side separately if you need it.
| Pick | Fit | Material |
|---|---|---|
| GEATaaT Clear Outer Dome | 14 x 22 in opening | Polycarbonate |
| RVGUARD Smoke Bundle | 14 x 22 in opening | ABS plastic and PC |
| ICON SL1422S Smoke | 14 x 22 in opening | Polycarbonate |
| Straight Creek Clear Bundle | 14 x 22 in opening | Not stated |
| XMK Inner Dome 14×22 | 14 x 22 in opening | ABS plastic |
Material and warranty
Polycarbonate domes state impact resistance in this group: the GEATaaT dome and the ICON dome are both polycarbonate, and the RVGUARD bundle pairs ABS plastic with PC. The XMK inner dome is ABS plastic with stated resistance to harsh chemicals. On warranty, the GEATaaT dome states 2 years and the ICON dome states 1 year, while the RVGUARD, Straight Creek and XMK picks state no warranty term. A longer stated term is worth more when the dome will sit in full sun year round.
Sizing Notes
- Match the dome to a 14 x 22 inch opening first, then check the flange against the clear roof around it.
- Compare flange figures across the picks: 18 x 26 inches for the GEATaaT and ICON domes, 17 x 25 inches for the Straight Creek bundle, and 23.6 x 16 inches for the XMK inner dome.
- Match the dome height to the opening depth: the GEATaaT and ICON domes are 4 inches high, and the Straight Creek bundle is 4.5 inches high.
- Check the warranty term before ordering: the GEATaaT dome states 2 years and the ICON dome states 1 year.
- Roof work and fitting are jobs for a qualified installer.
FAQ: power away from the grid
How do I replace a skylight in an RV?
Measure the roof opening first: every pick here fits a 14 x 22 inch opening. Order the dome or bundle that matches the failed part, then fit it with the screws in the box and the sealant where the bundle includes it.
How do I fix a leaking RV roof skylight?
Start by checking the seal around the flange and the screws that hold the dome. The Straight Creek bundle includes lap sealant, and the GEATaaT, RVGUARD and ICON picks include mounting screws for a fresh fitting.
How do I clean an RV plastic skylight?
Wipe the dome with a soft cloth and water, and avoid abrasive pads that can mark polycarbonate or ABS plastic. Clean the flange edge at the same time, since dirt there can hide a gap in the seal.
How do I replace an RV shower skylight?
Measure the shower roof opening, which is 14 x 22 inches for every pick here, then order the dome that matches the failed part. The XMK inner dome is made for shower roof openings and carries a clear window, while the RVGUARD and Straight Creek bundles replace the inner and outer domes together.
Which pick here states the longest warranty?
The GEATaaT dome, with a 2 year warranty stated. The ICON dome states 1 year, and the other picks state no warranty term.
