Dinner is on the table when the lights cut out, the fridge hums to a stop, and the phone on the counter has no charge left, which is when rich solar 200w vs newpowa 200w starts to matter for an RV roof or a cabin battery bank. The comparison below uses what each listing states: watts, voltage, size, weight, build and warranty terms. The short answer is that the Rich Solar listing states a 200W 24V panel with UL certification and a 25-year output warranty, while the Newpowa listing states a 100W 12V panel with rear-side gain, so the two are not matched on watts. Pick the Rich Solar example if your system runs at 24V and you want the stated 200W panel; pick the Newpowa example if your system runs at 12V and you want a lighter panel that can use reflected light.

Rich Solar 200W vs Newpowa 200W: side by side
| Solar panel | Solar Score | Watts | Voltage | Weight | Warranty |
|---|---|---|---|---|---|
| Rich Solar 200W 24V | 9.7/10 | 200W | 24V | 24.0 lb | 25-year output |
| Newpowa 100W 12V | 9.3/10 | 100W | 12V | 12.74 lb | 2-year workmanship |
These specs are rated by the maker and quoted from each listing on 5 November 2026.
Watts and voltage
The gap in stated watts is the first thing to settle. The Rich Solar listing states 200W at 24V, with a Vmp of 36.3V, a Voc of 43.5V and an Imp of 5.51A, and the bullets say the panel suits 24V and 48V battery setups. The Newpowa listing states 100W at 12V, with a Vmp of 17.1V and an Imp of 5.85A. On stated watts alone the two listings are not a matched pair, and the voltage split decides the setup each one fits: the Rich Solar example belongs with a 24V setup, and the Newpowa example belongs with a 12V setup.
Size, weight and build
The Rich Solar example is listed at 58.7 by 26.8 by 1.4 inches and 24.0 pounds, with an anodized aluminum frame, 3.2mm tempered glass and an IP67-rated junction box, and the listing gives load figures of 5400 Pa for snow and 2400 Pa for wind. The Newpowa example is listed in the bullets at 36.61 by 22.83 by 1.18 inches and 12.74 pounds, with pre-installed diodes in the junction box and pre-attached 3ft cables, with the same load figures of 5400 Pa for snow and 2400 Pa for wind. The Newpowa spec table disagrees with its own bullets, giving 38.58 by 20.87 by 1.18 inches and 13.2 pounds, so use the bullet figures when you compare. The Newpowa rear side captures reflected light, and the listing says to mount the panel 28-50 inches above ground for rear-side gains.
Warranty and certification
The Rich Solar listing states UL certification and a 25-year linear power output performance warranty, and it calls the panel PID-resistant. The Newpowa listing states a 2-year material and parts workmanship assurance, with output above 90% at 10 years and above 80% at 25 years, and it states no UL certification and no IP figure. On warranty length the Rich Solar example states the longer term, while the Newpowa example states output assurances across 10 years and 25 years.
What the listings leave unclear
The Rich Solar title claims 25% efficiency while the bullets state up to 24.8%, so use the bullet figure. The Newpowa listing is a 100W panel, so it does not answer the 200W side of the comparison on watts, and its bullets and spec table give different dimensions and weights. Neither listing states a figure for low-light output beyond the efficiency claim, and the Newpowa listing states no certification.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For solar panels, safety means a UL certification, an IP-rated junction box or another protection the listing names; the Rich Solar example states UL certification and an IP67-rated junction box, and the Newpowa example states none. Both state a warranty term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Rich Solar 200W 24V | 9.7 | 30 | 21 | 20 | 8 | 4 |
| Newpowa 100W 12V | 9.3 | 23 | 19 | 19 | 0 | 2 |
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 rich solar 200w vs newpowa 200w
Match the voltage to your battery setup
Start with voltage, because it decides the rest of the system. The Rich Solar example states 24V, with a Vmp of 36.3V and a Voc of 43.5V, and the bullets say it suits 24V and 48V battery setups. The Newpowa example states 12V, with a Vmp of 17.1V. If your battery bank and controller are set for 12V, the Newpowa example fits that setup; if they are set for 24V, the Rich Solar example fits. See the 12V vs 24V solar panel comparison for the same split.
Weigh the stated watts honestly
Do not treat the two listings as a matched 200W pair. The Rich Solar listing states 200W, and the Newpowa listing states 100W, so the Newpowa example gives a smaller panel for a smaller 12V setup. Size the controller and the battery bank from the watts each listing states, not from the comparison label. See the best MPPT solar charge controller for RV guide for controllers built for RV roofs.
Check the roof space and the mount
The Rich Solar example is listed at 58.7 by 26.8 by 1.4 inches and 24.0 pounds, so measure the roof space before you order. The Newpowa example is listed in the bullets at 36.61 by 22.83 by 1.18 inches and 12.74 pounds, so it takes less roof space, and its rear side needs 28-50 inches above ground for rear-side gains. Both listings state pre-drilled mounting: the Rich Solar listing states pre-drilled holes on the back frame.
Read the warranty before you buy
The Rich Solar listing states a 25-year linear power output performance warranty and UL certification. The Newpowa listing states a 2-year material and parts workmanship assurance, with output above 90% at 10 years and above 80% at 25 years. A longer stated warranty does not change the watts, so weigh it after voltage and size. See the best bifacial solar panels guide for panels that use reflected light.
