The best solar technology comes in solar panels with smart design, and this Newpowa solar panel has a smart, compact design that generates a good amount of power. That’s part of what landed it on the list of best solar panels with the likes of the Renogy 100 Watt Monocrystalline Solar Panel, Ring Solar Panel, and RAVPower Foldable Solar Panel.

Why We Like It – Newpowa 100 Watt Monocrystalline Solar Panel Review

Hundreds of positive customer reviews rank the Newpowa 100 Watt Monocrystalline Solar Panel as one of the best solar panels available on Amazon Prime, especially when it comes to RV and marine use. With up to a whopping 100 watt power output, it’s an efficient heavyweight contender.

  • Compact size relative to its large output
  • High 100 watt power capability
  • Sleek, low-profile yet durable design
  • Need to buy mounting material separately
  • Not portable


This Newpowa solar panel boasts a 100 watt panel, giving this panel high efficiency when it comes to keeping your batteries charged. Given that the panel is monocrystalline, the solar cells are more efficient and offer a high conversion rate of solar energy to energy output.

As far as marine solar goes, 100 watt panels usually don’t come in such compact, low-profile packages. That’s definitely a bonus, especially if you’re looking to have more than one 100 watt solar panel on your boat.

Although the panel is on the heavy side, you won’t be needing to transport it so that doesn’t really matter. It’s convenient that the diodes are pre-installed in the panel’s junction box, and a pair of pre-attached MC4 cables make for easier installation. All you need are Z brackets to hold the panel in place, which you have the option to purchase with the panel.


Coming in at under $100, the Newpowa is a great value, especially if you’re using it to power your module RV and for other RV marine usage. You can also rest easy knowing that the device has a 25-year power output warranty, so you can easily reach out to customer service if there are any problems with the panel later on. If you make sure that you’re installing the panel correctly, then you’re sure to get a lot of value out of it.

Solar power opens up a whole new world of possibilities for marine use, you’ll wonder how you ever got by without it.
