About product

Q CELLS HQC-405MLQPG10 is a PV module fit for both residential and commercial applications. Q CELLS engineers made the Q.PEAK DUO ML-G10 series durable and efficient while minimizing the amount of useful space required for their operation. Q.ANTUM is an advanced PERC technology developed by Q CELLS. The company employs a special nano coating on the rear of the cells to reflect the sunlight back and generate more electricity.

Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. Q CELLS made solar cells in HQC-405MLQPG10 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 20.6%. Q CELLS provides a 25-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years.

  • 132 half-cut Q.ANTUM cells
  • 405 W nameplate capacity
  • 20.6% efficiency
  • 1000 V DC maximum system voltage
  • Staubli MC4 connectors
  • 25 years of product and 25 years of performance warranty

More power and efficiency

An already high efficiency of 20.6% is further enhanced by Q.ANTUM technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, HQC-405MLQPG10 outputs 405 W of power.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. HQC-405MLQPG10 loses just -0.34% of efficiency for every 1.8°F above 77°F.

High quality standards

Multiple tests are part of the Q CELLS tight production requirements, which offer the highest level of quality assurance. Because of the facilities' high degree of automation, the business is able to uphold strict standards and minimize the number of warranty claims to an absolute minimum.

Reliability and degradation resistance

Slow degradation over the next 25 years is guaranteed by Q CELLS. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 86% of original performance after the 25 years are over. This 405 W Q CELLS solar panel also comes with a generous 25-year product warranty.

Enhanced frame design

HQC-405MLQPG10 design makes it ideal for residential and commercial rooftops. Strong 1.26" frame made from anodized aluminum increases durability and strength. The model can support a heavy snow load up to 5400 Pa. The back of the panel can handle 4000 Pa, ensuring that your system will survive the strongest of winds.

The best battery choice depends on your solar system capacity. Feel free to contact our engineer Vic at vic@a1solarstore.com to find the best fit
Can you provide details on the lifespan of these panelss/
01/02/2024, 12:32
These panels have a 25 product and performance warranty. Usually solar modules work even after the warranty period, but the manufacturer doesn't guarrantee that.
are these panels suitable for snowy regions? I live in Idaho
06/12/2023, 04:03
Yes. These panels are very durable and can hold up to 5400 Pa of snow load
Is this the 6 busbar or 12 busbar model?
02/08/2023, 11:59
This model uses a Q.ANTUM DUO Z technology with zero gap cell layout


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
