High Efficiency of 19%

A higher than average efficiency of 19% is achieved due to the famous Q.ANTUM DUO Technology, which reduces electrical and optical losses by halving the current passing through each cell. Half-cut cell design also increases the shading tolerance of Q CELLS 340W solar panels.

Extreme Weather Rating

The high-tech aluminium alloy frame of the Q Cells 340 W solar module is certified for high snow (5400 Pa) and wind loads (4000 Pa).

Quality and Reliability

All Q Cells 340W G8 solar panels are quality tested. Reliability of solar panels is another crucial concern of Q Cells. The manufacturer guarantees at least 85% of nameplate power rating in year 25. The degradation rate of Hanwha Q CELLS 340 watt panels is lower than average numbers on the market.


Low Degradation

Anti LID Technology, Anti PID Technology and Hot-Spot Protect and Traceable Quality ensure low degradation rate, maximum 0.54% per year.

Improved Cell Design

Q-Cell G8 340W solar panel consists of 6 x 20 monocrystalline Q.ANTUM solar half cells. The half-cell design minimizes cell stress reducing the potential for micro cracks. Q CELLS 340 reviews also point out the impressive all-black design.
