High energy conversion rate allows to use space efficiently

Q.PEAK DUO provides at least 20.4% efficiency, whereas average numbers in the industry are closer to 18%-19%. Higher energy conversion rate means that you need less space for a powerful solar installation.

Thorough testing ensures a quality product

Q Cells panels undergo the most comprehensive Quality Controlled PV program in the industry of the independent certification institute TÜV Rheinland. Third party testing ensures that the customer receives only the best product possible.

Excellent performance in all kinds of weather

The panels provide great production levels even in low-light conditions: on cloudy days and in the winter. Modules are ready for extreme weather conditions: solar cells are protected by a high-tech aluminum alloy frame, certified for high snow (5,400Pa) and wind loads (4,000Pa).

25 year warranty both for product and performance

Q Cells offers a 25 year warranty for the product and its power output – much higher than standard numbers in the industry. A module loses no more than 2% of its output in the first year and no more than 0.5% in the following years. Your panel retains over 86% of its output by the time the warranty runs out.

I actually love q cells and i recommend them to all my friends to the point that they tell me to shut up about it. but seriously, the price is not that much higher than chinese panels, but i feel like the panels themselves are superior. 25/25 warranties are no joke either

I ordered a pickup because one of their centers was nearby. So I drove there and got the order, checked it on the spot just in case. They warned me about driving carefully and all that. I delivered the package home safely. good experience overall.

The panel can be used for either one of those. It is slightly larger than a standard 60-cell panel, so you have to plan the installation accordingly.

what’s the minimum order size?

This panel doesn’t have a built-in inverter so by default it produces direct current.

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%.

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
