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.

is this for residential or commercial systems?

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?
03/18/2022, 13:07
The min qty is 6 panels.
does it produce direct or alternating current?
03/15/2022, 14:01
This panel doesn’t have a built-in inverter so by default it produces direct current.
