At a campsite at dusk with a dead phone and a battery bank waiting for morning sun, the panels on the roof decide how much charge the next day brings, and the choice in rich solar 100w vs newpowa 100w is an uneven one. Pick the Rich Solar side for the larger panel setup, and pick the Newpowa example only where a smaller panel fits the plan, because the two listings do not describe panels of the same size or voltage. We compared the two listings on stated watts, voltage, size, weight, mounting and warranty terms.

Rich solar 100w vs newpowa 100w: side by side
| Solar panel | Solar Score | Watts | Voltage | Weight | Warranty |
|---|---|---|---|---|---|
| RICH SOLAR 100W Slim 2 Pack | 9.7/10 | 100 | 12 | 27.4 pounds | 25-year power; 5-year material |
| Newpowa 35W 24V | 9.3/10 | 35 | 24 | 5.19 pounds | 2-year material |
We copied each rating from the seller’s listing as the brand states it; data date 4 November 2026.
Watts and voltage
The watt gap is the whole story here. The Rich Solar listing describes a 2 pack of 100 Watt panels for charging a 12 volt battery, with 5.52 amps stated. The Newpowa listing describes a 35W panel for 24 volt batteries, with 34.40 volts at maximum power and 1.02 amps at maximum power. The two panels therefore belong to different battery voltages as well as different watt classes, so the comparison is uneven by construction: the Rich Solar example is the only 100 Watt panel here, and the Newpowa example is the only 24 volt panel here.
Size and weight
Size and weight follow the watt gap. The Rich Solar panels measure 50.0 by 15.8 by 1.2 inches, and the spec table lists 27.4 pounds without saying whether that covers one panel or the 2 pack. The Newpowa panel measures 20.67 by 15.75 by 1.10 inches, with 5.19 pounds stated. The Newpowa example is therefore the smaller and lighter panel of the two, which matters on a roof or mounting run with limited room, while the Rich Solar pair suits a larger mounting area.
Mounting and build
Mounting details differ in what each listing counts. The Rich Solar listing states 14 pre-drilled holes compatible with ground mounts, Z-brackets, side pole mounts and tilt mounts, with strong high transmission anti-reflective coated tempered glass and an anodized aluminum frame. The Newpowa listing states pre-drilled mounting holes on the frame without a count, with a pre-attached 3 foot bare-end wire and no connectors stated. The Rich Solar listing also states a 3 foot cable with connectors and work in series or in parallel, while the Newpowa listing states 10BB cells for higher cell efficiency.
What the listings leave unclear
A few points need care. The Newpowa listing is a 35W panel, so it leaves the 100W side of this comparison without a matching Newpowa example. The Rich Solar weight of 27.4 pounds is ambiguous, because the spec table does not say whether it covers one panel or the 2 pack. The Newpowa listing states no glass type or frame material, and no connectors beyond the bare-end wire, so those points cannot be compared with the Rich Solar glass and frame claims.
Two examples
RICH SOLAR 100W Slim 2 Pack
A 2 pack of 100 Watt monocrystalline panels for RV, trailer and motorhome use, with a 3 foot cable with connectors, 5.52 amps stated and a 25-year limited power output term.
Pros
- 100 Watt panels in a 2 pack for RV, trailer and motorhome use
- 5.52 amps stated for charging a 12 volt battery
- 14 pre-drilled holes for ground mounts, Z-brackets, side pole mounts and tilt mounts
- 25-year limited power output term with a 5-year material and workmanship term

- Stated for charging a 12 volt battery, not for 24 volt batteries
Detailed Review
The listing states a 2 pack of 100 Watt monocrystalline panels for RV, trailer and motorhome use, with a 3 foot cable with connectors, 5.52 amps for charging a 12 volt battery, and work in series or in parallel. It states excellent low light performance on cloudy days, mornings and evenings, strong high transmission anti-reflective coated tempered glass with an anodized aluminum frame, and 14 pre-drilled holes compatible with ground mounts, Z-brackets, side pole mounts and tilt mounts. The spec table lists 27.4 pounds and 50.0 by 15.8 by 1.2 inches, without saying whether the weight covers one panel or the 2 pack. The warranty terms are a 25-year limited power output term and a 5-year material and workmanship term.
Who it's for: owners building a 12 volt panel setup for an RV, trailer or motorhome who want a 2 pack with a long stated power output term. Who should skip it: anyone with a 24 volt battery setup, or anyone who needs a smaller panel than the stated size.

Safety and Warranty
What this listing states. Strong high transmission anti-reflective coated tempered glass and anodized aluminum frame stated; certified to withstand challenging environmental conditions, so safety scores 7 of 10. 25-year limited power output; 5-year material and workmanship stated. It does not say everything a buyer needs, such as who pays return shipping, so warranty scores 4 of 5. See How We Pick.
Panels make voltage in daylight. Keep connectors covered until you connect them, check the panel's stated open circuit voltage and current against your controller or power station input limits, and use cables rated for the current. Roof and permanent mounts belong to a qualified installer.

Cons
- 35W panel, not a 100W panel, so it does not match the 100W side of this comparison
- Stated for 24 volt batteries, not for 12 volt batteries
- No glass type or frame material is stated
- Bare-end wire stated, with no connectors stated
Detailed Review
The listing states a 35W 24V monocrystalline panel for off grid systems, with 10BB cells for higher cell efficiency, 34.40 volts at maximum power and 1.02 amps at maximum power. It states a 20.67 by 15.75 by 1.10 inch size, 5.19 pounds, a pre-attached 3 foot bare-end wire and pre-drilled mounting holes on the frame. The listing states a 2-year material and parts workmanship assurance, with power output greater than 90% at 10 years and greater than 80% at 25 years. The listing does not describe a 100W panel: every watt figure it states is 35W, so it cannot match the 100W side of this comparison on watts.
Who it's for: owners with a 24 volt battery setup for an RV, boat, camper, trailer or gate opener who want a smaller panel with stated power output assurances. Who should skip it: anyone shopping for a 100W panel, or anyone with a 12 volt battery setup.
Its Solar Score of 9.3/10 comes from performance 21/35, build 19/25, value 18/25, safety 0/10 and warranty 3/5: 61 of 100 points, placed on our 9.2 to 9.8 scale.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For solar panels, safety means a stated glass type, frame material or another stated protection feature: the Rich Solar listing states tempered glass, an anodized aluminum frame and certification for challenging environmental conditions, while the Newpowa listing states no safety feature, so its safety line is empty. Both listings state a warranty term, a 25-year limited power output term with a 5-year material term for Rich Solar, and a 2-year material assurance for Newpowa. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| RICH SOLAR 100W Slim 2 Pack | 9.7 | 30 | 21 | 21 | 7 | 4 |
| Newpowa 35W 24V | 9.3 | 21 | 19 | 18 | 0 | 3 |
We place weighted points on a scale whose ends are 9.2 and 9.8. Because the mapping is straight, a unit with more points never shows less.
Rich Solar 100w vs Newpowa 100w: which should you choose?
Choose the Rich Solar side for a 12 volt panel setup where a 100 Watt panel pair fits the mounting area, with a 25-year limited power output term stated. Choose the Newpowa example for a 24 volt battery setup where a smaller panel fits the plan, accepting that it is a 35W panel rather than a 100W match. Match the panel voltage to the battery bank, and match the panel size to the mounting area, before ordering.
