Whether you are planning to get solar panels for an RV, your boat, or your off-grid farmhouse, solar panels are becoming cheap enough for many situations. This Newpowa Solar Panel Review is a simple follow-up on my research for the solar panel I use in my home in Africa.
The NewPowa brand is becoming more and more popular because they offer good quality panels at competitive prices. Don’t get me wrong. I am not saying that the NewPowa Solar Panels are the best panels out there. What I am saying is that if you want solar panels that work, these panels will serve you well for the money.
The most popular NewPowa solar panel is the 100 Watt Polycrystalline. They also have the monocrystalline 100 Watts panels for a little more money. Although the 100 Watt panels are very popular, I can see the NewPowa 200 Watts 12 volts monocrystalline solar panels becoming even more popular. I just ordered a set of 150 Watt panels for our home in Africa. A few months ago, the 150 Watt solar panels were not easily accessible and the 200 Watts and 250 Watt panels are usually 24 volts. With a 24 volts solar panel, you will need a 24 volt bank of batteries to maximize your panels. There is also a 150 W and 175 Watt Mono NewPowa Solar Panel.
Find below my review of the NewPowa 100 Watts Polycrystalline Solar Panel. These panels share a lot in common with the other panels with different power ratings. If this review is helpful, you will be able to decide whether to go for this or any of the other NewPowa Solar Panels.

Newpowa Solar Panel Rewiew: 100 Watts Polycrystalline or Mono Photovoltaic Pv
Here are a few of the things to take note of when considering the purchase of the 100 Watt Newpowa Solar Panel
How much Power does it Output?
The 100 Watt rating on the Newpowa solar panel refers to the peak power that the panels can out put when placed under direct sunlight. It is the ideal case. In reality you will not get this peak power all through the day. If you have direct sunlight for 5 hours, then the solar panels should ideally output 500 Watts of power.
This means you can use the solar panels to ideally supply 500 Watt of power to your battery or to any direct current load that may be connected to the panels. In my own case I bought my solar panels to charge my 200Ah battery. It is more realistic to assume that the panels will only supply 80% of the max power rating even when you have an almost ideal situation. If however there is some shade, some cloud or your placement does not allow for adequate sunlight to your panels the amount of power output will be affected.
What can you use the Newpowa Solar panels For?
These panels are suitable for various applications. From my research, they have been used for RVs, Caravans, Marine, Off-grid applications (this means that they can be used within a complete system that does not depend on the electric grid from the city), they can also be used to generate solar energy which is fed back into the electric grid, some people have installed them on their boats and so on. They would function anywhere electric power is needed as long as you have a way of placing them as directly as possible under the sunlight.
Basically the 100 watts Newpowa solar panels can be used in any application that requires the charging of a 12 volts battery. It can also be used for 24 volts and 48 volts battery systems, however you will need to connect more than one panel in series.
Newpowa Solar Panel installation
There is an option to purchase the Newpowa Solar Panel with the Z brackets needed to install the panels. You will also need an extension cable. The cable attached to the panel is only about 36 inches long.
You may need to purchase more materials for mounting your panels on a roof if the included z brackets are not enough. You may need extension cables. An MC4 removal tool may come in handy. You may need it to unfasten the connectors if you connected them wrongly or you need to unfasten them for any reason.
The 100-watt Newpowa Solar Panels come with male-female MC4 connectors. These are the standard connectors that come with the solar panels. They are designed for easy connection without a tool, but they do not easily come apart. You will need a tool to pull them apart. This is so that they don’t accidentally come apart once they are in place. I suggest that you estimate the distance between your batteries and the solar panel, and purchase an extension cable as needed. I have my panel installed on the roof so I needed about 50 feet of extension connector.
The extension can also be purchased on Amazon (Check Prices here).
Pre-drilled holes for Easy Installation
The 100 Watt Newpowa Solar Panels have pre-drilled holes that make installation on rooftops and other places easy. These pre-drilled holes are almost standard on most solar panels of this size. It can be very tedious to install solar panels on the roof if you have to drill the holes yourself.

Corrosion-resistant aluminum frame for extended use
The 100 Watts Newpowa Solar is well-built with a corrosion-resistant aluminum frame. It feels good to know that your solar panels have been built to last. The aluminum frame is anodized, which means that it will maintain a beautiful shiny look for a long time.
Since the panels will be kept outdoor for years and years, an aluminum frame is ideal to prevent corrosion. According to the manufacturers the panels have been tested to withstand high winds of up to 2400 Pa which is approximately 50 pounds per square foot. This means that the panels can withstand winds that feel as if a 50-pound weight that is about 1 foot by 1 foot is placed on it. And for snow loads, it can withstand up to 5400 Pa which is approximately 112 pounds per square foot. Well think about your weight and you would be able to guess how much snow load your solar panel can withstand. Again, this has become a standard for most solar panel manufacturers. It is good to know that the 100 Watts Newpowa Solar panel is not substandard in this regard. I did not test this obviously.
Newpowa Solar Panel – Anti-Reflection coated glass
The glass covering on the front of the Newpowa panels is 3.2mm thick, tempered and patterned. This ensures that the glass is not easily broken either while driving around with the solar panels on your RV or on your boat. It also protects it from little things that may drop on it on a windy day.
Newpowa Waterproof IP-65 Rated Junction Box
The Newpowa Solar panel has a junction box at the back through which the solar panel is connected to your batteries or direct
current devices. This junction box contains electrical components that must be protected from dust and moisture. The Newpowa panels are IP-65 rated which simply means that they have complete protection against environmental particles as well as low-pressure water jets. They however are not protected against continuous submersion in water. To be protected against continuous submersion in water, the junction box would have to be IP-68 rated. The second 8, representing the higher level of protection against moisture. Solar panels only need protection against rain so an IP-65 rating is more than adequate.
Where are the Newpowa Solar Panels Manufactured?
Well, you guessed right. For the price that they go for, they are not manufactured in the USA. Newpowa Solar Panels are manufactured in China. According to the manufacturer they are also manufactured in Vietnam and Mexico.
Newpowa solar panel dimensions
- 23.07 x 19.88 x 1.18 inches
- 9.02 pounds
- 44.49 x 19.88 x 1.18 inches
- 16.31 pounds
- 58.35 x 26.57 x 1.38 inches
- 26.7 pounds

The size of the solar panels is good for most applications.
NEWPOWA SOLAR PANEL specifications– 100 watt Monocrystalline Panel
Cost of the 100 Watt Eco Worthy Solar Panel
At the time of my review, the 100w polycrystalline Newpowa Solar Panels were the most competitive on price on Amazon. Although the solar panels are polycrystalline, they are rated to output the same 100 watts that the monocrystalline one would output. The price difference may not be much when buying just one panel, you would recognize the savings if you have to buy more than 5 panels. It is not unusual to require 10 -15 panels to completely take a 3 bedroom cottage off the grid.
100 Watt NewPowa Solar Panel Pros
- Its construction meets the basic standards for solar panels.
- The Newpowa company has been around for a few years. Not very long but long enough to have a reputation to protect.
- It is cost-effective. It is not way cheaper than all the other panels but, the last time we checked it gave the best value for the money.
- They seem to have good customer service.
100 WATT NEWPOWA SOLAR PANEL Cons
- The panels are slightly bigger and heavier than similar models.
- The connecting cable attached to the panel is too short. It’s just 90cm (3 feet) long. You would need to buy an extension cable.
- It is just one panel. If you are new to this, you are better off going for the KIT. The starter kit contains all you will need to start using your solar panel excluding the battery and the Power Inverter.
The 100 Watt NewPowa Solar Panel has a customer review of 4.5 out of 5 on Amazon. Many of the reviews were 5 stars and a good number of the reviews were from repeat buyers.
Monocrystalline or Polycrystalline?
I always go for monocrystalline because I find that with low light, the monocrystalline solar panels perform better. If you have the budget, go for a mono. In my opinion, you will get your money back with the extra power you get from the performance of the panels with low light.
The 100 Watt NEWPOWA Solar Panels give good value for money. If you are going for a large installation (10+ panels), this is the way to go. If however you simply need one panel, there is no major difference between the NewPowa Solar Panel and those of other brands. Go for the NewPowa Solar panel because it delivers good quality at an affordable price.
