About product

Q.PEAK DUO is a very powerful module with 430W power output. It performs amazing in all types of weather. The panel from German engineers is a great choice for commercial and large scale installations. 


  • 430W Power Output
  • 20.5% efficiency
  • 0.54% degradation rate
  • MC4-Evo2 connectors
  • Certified for high snow (5400Pa) and wind loads (2400Pa).

Q.ANTUM technology ensures high performance

A module brings 20.5% efficiency with higher energy yield per surface area due to Q.ANTUM technology by German engineers. It is especially advantageous if you are dealing with limited space for a system.

Great production in all kinds of weather

The model brings optimal levels of production even in low-light conditions. High temperatures have little effect on the performance of a module. The panel isn’t afraid of harsh weather, being certified for high snow (5400Pa) and wind loads (2400Pa) and reinforced by anodized aluminium frame.

Reliable and long-lasting

Safe and quality design of Q.PEAK DUO is backed up by 12-year product warranty and 25-year linear performance warranty. You can expect the PV module to retain at least 85% of their initial power.

I bought these panels in the middle of the spring and right after the installation there was a tornado here in dakota. but the panels survived it very well to my surprise. I obviously had to clean them afterwards, but the production was the same. great stuff.

We’ve purchased a batch of QCELLS panels for our gas station in Oklahoma. The staff of a1solarstore was super professional. Since our order was big, we even received a little discount. As for panels, they perform amazingly and we are very happy with our choice. Thank you!

Your solar calculator was of great help, a super useful tool! Thanks for the fast delivery, we began the installation two days ago.

The panel is quite heavy, and i had to reinforce the roof for a PV system. I’m also not a fan of the look. But its properties are very good and the performance is outstanding. It’s a good price for QCells product and the service that the shop provides is on point.

can you ship them to Montreal?
08/19/2021, 16:46
Unfortunately, the shipment is available only for the contiguous US.
is it good for a ground-based installation?
08/02/2021, 11:35
Yes, it is a great choice for ground installations.
Hi, what’s the Voc of this model? like, in real world?

Hello. At normal operating conditions it reaches 46.56V, according to the datasheet.


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
