About product

ZXM7 is part of the Znshinesolar Series — one of the most recent made by ZnShine Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight. 

Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. ZnShine Solar made solar cells in ZXM7 two times smaller than the standard size, thus reducing power loss and improving low-light behavior. As a result, the panel achieves an impressive efficiency of 21.13%. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. ZnShine Solar provides 12 years of product warranty and guarantees that after 30 years, performance will be at 83.5% or more. 

  • 540 W power output
  • 144 half-cut PERC cells
  • 21.13% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12-year product and 30-year performance warranties

Higher efficiency of up to 21.13%

ZXM7 guarantees the highest power output. PERC technology and potent anti reflective coating result in 21.13% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.

Heat-resistant performance

The heat is less of a problem with this module: with one of the industry's lowest temperature coefficients, ZXM7 loses just 0.35% of efficiency for every 1.8°F over 77°F.

Quality and reliability

ZXM7 receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. ZnShine Solar is dedicated to quality, safety and reliability to ensure you get the very best.

Reliability and degradation resistance

ZnShine Solar guarantees limited degradation over the ensuing 30 years. The performance will only degrade by a maximum of 2% the first year, and then only by a maximum of 0.50% yearly after that. After the 30 years are over, your modules will still show at least 83.5% of nominal capacity. A substantial 12-year product warranty is also included with this 540 W ZnShine Solar solar panel.

Enhanced frame design

This model's construction makes it perfect for both residential and business rooftops. Durability and strength are increased by using a strong, robust frame built from anodized aluminum. A significant snow load of up to 5400 Pa may be supported by the model. The panel's back can support 2400 Pa, assuring that even the strongest winds won't damage your system.

At first, I was hesitant to post a review before I had turned on the solar panels and begun net metering. Now that I've started to use them, I give ZNshine panels a perfect score. So far in the month of December, we have been extracting and supplying the grid with 50 kilowatts of solar power daily. We are certain that our investment will be paid back within a few years.

On a sunny day, our current ZNshine 6.5 kW system generates 40 kWh. We set them out on the ground, and the bifacial technology significantly increases the output. We received excellent service and a fair pricing from A1. Highly recommend the store and the panels

What kind of regulator is needed to manage power into battery banks? and can you suggest an inverter to supply 48v 100 amp AC breaker panel? I built a home in Colo with one of your systems and it worked terrific.ThanksJim

We don't want to miss anything important, and such a broad question needs more than just a short reply. You can click "Magazine" at the very top of our website. We have an entire compilation dedicated to PV system design. We would also be happy to get a call from you
How many 150 watt LED lights can I run off of the solar panel
12/17/2022, 11:53
Assuming the panel is outputting at least 80% of its nominal capacity, you can run 3 such lights off of it


How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
Do you offer discounts?
We do offer discounts for orders of over 50 units. Please contact us for details.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South
