What Is The Newpowa 200w 12V Rigid Monocrystalline Solar Panel?

“The Newpowa 200 Watt 12V Monocrystalline Solar Panel is a rigid PV unit designed to charge batteries. It’s monocrystalline solar cells collect free sunlight and convert it to usable direct current (DC) electricity. The panel can be used as a single unit or connected in series or parallel forming a solar array. Fitted to vehicles, trailers and boats for providing power in off-grid situations. It can also be used in DIY rooftop installations and home or business solar projects. Such as providing power for a shed, greenhouse, garage, workshop, cabin or water pumping.”

A Bit About Newpowa

Newpowa was founded in Las Vegas in 2013 but is now based in Ontario. They have expanded their operations into Germany and ship worldwide. They manufacture solar panels, solar suitcases, power stations, batteries, controllers and inverters. The products are manufactured in China and assembled in the United States of America.

How Does The Newpowa 200w Solar Panel Work?

Let’s start by taking a look at how the 200 watt solar panel works

Specs Newpower 200w Solar Panel
Solar CellMonocrystalline
Wattage200 Watts
EfficiencyClass A High Efficiency
Dimensions64.57 x 26.57 x 1.38inch/1640 x 678 x 35mm
Maximum Operating Voltage (Vmp)17.0V
Maximum Operating Current (Imp): 11.76A
Open-Circuit Voltage (Voc): 20.23V
Short-Circuit Current (Isc): 12.45A
Maximum System Voltage: 1000V DC

The unit is 5.4ft x 2.2ft x 1.3inch or if you prefer your dimensions in metric 1.64m x 0.68m x 35mm. Like all 200w panels its weight is related to its size coming in at 27.5lbs/12.05Kg.

The backsheet is made from TPT (Tedlar Polyester Tedlar). With the monocrystalline solar cells attached to it sandwiched between layers of EVA (Ethylene Vinyl Acetate).

Sino Voltiacs Says;

TPT is the abbreviation of Tedlar Polyester Tedlar and is a composite-layer film used as covering foil on the backs of solar modules. (Source;

I don’t know if there is then a layer of EFTE (Ethylene Tetrafluoroethylene) Newpowa does not say. But it is fronted with highly transparent, low iron tempered glass. 

It is framed in heavy duty anodized aluminum which has pre-drilled holes to aid with mounting. Newpowa say the junction box on the rear has pre-installed diodes. It comes complete with a 3ft cable with MC4 connectors. 

Junction box with 3ft cable and MC4 connectors. 
Monocrystalline Solar Cells 

I do not know how many solar cells make up the solar panel Newpowa doesn’t say. But based on the fact that individual solar cells produce around 0.46V each. This 200 watt solar panel has a VMP of 17V. It would suggest it is made up of 36 individual solar cells. 

If anybody knows something different let me know in the comments section at the end of the post. 


While there is no stated efficiency rating for the solar panel. The solar cells are described as class A meaning they are capable of producing the highest ratings. But I am unwilling to put a number on it. Because I could be wildly off the mark as the typical efficiency can vary between 15% and 20%

Amp Output

The panel has a maximum operating current or IMP of 11.76. This means at full power under ideal conditions it will produce 11.76Ah for battery recharging. So assuming 5 hours of perfect sunshine 11am to 4pm. It is capable of producing 58.8Ah of battery charging power.

Varta Lead Acid Battery

Keeping a 100Ah lead-acid battery fully charged would be no problem in the summer months. A 100Ah lithium based battery that can be discharged by up to 80% of its capacity. So this might prove to be a bridge too far. But if you regularly discharged to 50% maximum it would be feasible.

Connecting In Series Or Parallel

The 200w panels can be connected in series or parallel. If you don’t know, connecting in series will increase the voltage incrementally. 

For instance if you connect two panels together the voltage will increase to 24V (12 x 2 = 24). Connecting three panels together will increase the voltage to 36V (12 x 3 = 36) and so on. But the amperage will stay the same 11.76A 

Connecting in parallel will increase the amperage incrementally but the voltage will stay the same 12V. 

For example two panels connected together will increase the amps to 23.52A (11.76 x 2 = 23.52). Connecting three panels together will increase the amps to 35.28A (11.76 x 3 = 35.28) and so on.

What Can I Use The Panel For?

The solar panel has a wide variety of uses for generating electricity in off-grid situations. The most obvious being installing them to a RV, camper, motorhome, trailer, caravan or boat.

Recreational Vehicle

But because solar power is becoming more popular there are several other uses for the panel. So what kind of other situations can the panel be used to generate electrical power?

  • Rooftop installations: Very small houses, garages, workshops, businesses, cabins, sheds, lodges and commercial vehicles.
  • Providing power to run equipment: Water pumps (garden). Wi-Fi, computers, farming (electric fences), hydroponics and exterior lighting

It can be mounted by directly screwing it onto a vehicle or boat using the pre-drilled holes. There is always the option of mounting it flat on a frame or an adjustable tilt mounting. Or if you are mounting on a flat roof a fixed tilted frame.

Whichever way you choose, Newpower does provide a range of frames for mounting and z bracket kits.

What’s Good About The Newpowa 200 Watt?

Good Performance

Below is a screenshot of a review on the Newpowa website of a customer’s 200w panel in action. The panel is producing 181w with a charging current of 13.06A.

The panel producing 181w with a charging current of 13.06A.
It’s Well Made

You can see from the video how well made the panel is. It’s sturdy construction along with the extensive output warranty. Means you will be enjoying free electricity generation for many years to come


Coming in at under $225.90 on Newpowa’s website. With its performance, quality of workmanship and warranty it is hard to beat.

What’s Not So Good About The Newpowa 200 Watt?

No Installation Instructions

Some reviews say there are no installation instructions with the unit. I am not sure this is a fair criticism as each individual installation is different.

Efficiency Not Specified

The efficiency of the solar panel isn’t stated there is a reference to it saying class A high efficiency cells. But the other three panels I use in comparison all give their ratings.

So it’s a bit of a guessing game with the Newpowa. I have come up with an efficiency percentage range based on similar panels. But the exact figure would be helpful and desirable.

All the panels are roughly the same size. With the ACOPOWER and Rich Solar panels being a little shorter but wider. The Newpowa and Renogy being a little longer and narrower. 

I guess choosing on the basis of size will come down to the space and schematic of your installation. They all weigh roughly the same with the Newpowa carrying an extra pound over the other three.


They are all constructed from the same materials as the Newpowa and have similar output warranties. All say they have high wind pressure, snow load, hail and extreme weather tolerances. The glass descriptions are slightly different.

  • Newpowa say; Highly transparent, low iron tempered glass
  • Rich Solar and ACOPOWER say; High transmission, anti reflective tempered glass
  • Renogy says: Anti reflective, high transparency, low iron tempered glass. They are also guaranteeing no hot spot heating.
 Heavy duty anodized aluminum frame

Except for Newpowa mainly because it doesn’t say they all have IP65 waterproof junction boxes. But I guess it does because Rich Solar, ACOPOWER and Newpowa have built-in bypass diodes. This helps with power drops from shading but Renogy doesn’t say. 

All have predrilled holes in the frame to help with installation and cables with MC4 connectors.

Efficiency And Performance

If you go take a look at the reviews for the four 200w panels. You will see that even though the efficiencies vary the performance is roughly the same. For example you hardly ever achieve the 200 watt rating.

Typically achieving 165w to 180w plus and this is true for all wattage solar panels. But why is this? If you are new to solar read on. If you are an old hand with solar you can probably skip this bit.

The performance and efficiencies vary because the panel’s output is measured under test conditions. Either STC (Standard Test Conditions) or NOCT (Nominal Operating Cell Temperature).

But in the real world because of weather, temperature, available sunlight and seasonal conditions. Not to mention the panel’s orientation towards the sun. The panel’s output potential fluctuates and it is difficult to replicate the same test conditions.

This may seem odd to you but there has to be a specific set of rules for testing. Otherwise there would be potential for manufacturers to make wild claims about their panels.

But from amongst these four panels the Rich solar has the highest efficiency rating. The Newpowa may be higher but it doesn’t give an actual number. It just says grade A high efficiency solar cells so I am unable to say for sure.

Newpowa, ACOPOWER, Renogy And Rich Solar 200w Rigid Solar Panels 

So all in all there isn’t that much difference between these four 200w solar panels. Your choice may come down to personal manufacturer preferences. But I would say that the Newpowa is $225.90 making it $74.00 cheaper than the Renogy equivalent. I will leave the decision in your hands.

My Closing Thoughts

The Newpowa 200w rigid solar panel is quite clearly not that much different to other similar panels. The construction, dimensions, performance, and overall look match other 200w products. Where it does score is on the price.

If you are installing several panels there is a significant saving to be made over some other makes. I would love to be able to say it has this feature or that feature that is better than another make. But I can’t because this review has shown that the major benefit of this panel is the price.

When all is said and done this might turn out to be the deciding factor for you. Especially if you do not have an affinity to a particular manufacturer or it’s your first solar installation.

I hope you enjoyed this review and have found it helpful. If you have any questions about the Newpowa 200w 12V Monocrystalline rigid Solar Panel. Or want to leave your own personal review, please feel free to leave a comment below.

    1. Thanks, Steve for giving a profound description of Newpowa portable soler panel and seems like the 12volt 200 watt soler panel is a value for money product although the company doesn’t specify some key features makes it little less trustworthy. Soler power is a renewable energy and great alternative for traditional power system, it also vey environment friendly in nature so we may see more of these soler panels. The size is very convenient and install it rooftop of house or truk is possible and the $220 price makes it a real value for money deal.
