Compared to other brands, the price of Q CELLS modules is a major advantage. We have been installing them for our clients for more than 8 years and never had a single problem with performance or craftsmanship.

FAQ

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%.
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

About product

Q. PEAK DUO L-G8.2 425W is an ideal model for commercial and utility uses. It takes full advantage of groundbreaking Q.ANTUM DUO technology in combination with superior cell interconnection.

This module can boast a very low levelized cost of energy thanks to superior yields, which are guaranteed by 144 Q.ANTUM DUO mono half cells and a 12 busbar design. Being an ideal fit for solar plants due to lower BOS costs, this model can also be used in residential systems, providing German engineering quality at a competitive price.


Low energy costs

A higher than average efficiency of 19.8% is advantageously complemented by Q.ANTUM DUO technology that reduces the amount of current flowing through each cell by 50%. This leads to significantly decreased optical and electrical losses, allowing for optimal performance in a wide range of temperatures.

Enduring high performance in all weather conditions

Q CELLS implements Yield Security to make the performance last for decades: Anti-PID, Anti-LID, Hot-Spot Protection and Traceable Quality Tra.Q. This model also behaves extremely well in low-light and high-temperature conditions, which makes it very versatile.

Handling hail, wind and snow

A 35 mm lightweight frame made from aluminum alloy and 3.2 mm of thermally pre-stressed protective glass make sure this module won’t budge under the worst conditions. The front side of the modules can resist a 5400 Pa load, and the back side 2400 Pa.


25 year performance warranty

Slow degradation over the next 25 years is guaranteed by the manufacturer. The output will suffer a decrease of no more than 2% during the first year and the module won’t lose more than 0.54% of performance annually thereafter. Your modules will conserve at least 85% of nameplate capacity 25 years later. The manufacturer also offers a 12 year product warranty.
