Q.PLUS BFR-G4.1 – INNOVATION AND EXCELLENT PERFORMANCE
The new high-performance module Q.PLUS BFR-G4.1 is the ideal solution for all applications thanks to its innovative Q.ANTUM cell technology. The world-record cell design was developed to achieve the best performance under real conditions – even with low radiation intensity and on clear, hot summer days.
Q.ANTUM PHYSICS – MORE LIGHT. MORE PERFORMANCE. MORE ELECTRICITY
Q.ANTUM combines the best characteristics of all available cell technologies to obtain high performance under real conditions, all with a low levelized cost of energy (LCOE).
Don't maximize, optimize: The rear surfaces of Q.ANTUM solar cells are treated with a special nano coating that functions much like a typical household mirror. Rays of sunlight that would otherwise go to waste are reflected back through the cell to generate more electricity. This enhances the electrical properties, considerably increasing the efficiency.
Versatility, reliability and proven performance are the hallmarks of the Q CELLS Q.PLUS series which has been optimized across the board: improved yield, higher operating reliability and durability, and a more intelligent design. Hanwha Q CELLS guarantees this by offering an extended 12-year product warranty and one of the best linear performance warranties on the market.
In addition to the Hanwha Q CELLS Triple Yield Security with Anti PID Technology, Hot-Spot Protect and Tra.Q (100 % traceable quality), Q.PLUS solar modules include the following features:
High power class with Q.ANTUM cell technology
High safety due ammonia-resistant junction box and robust connectors
Excellent stability: tested for wind loads up to 4000 Pa and snow loads up to 5400 Pa
Up to 10 % reduction in logistics and storage costs as compared to the G3 generation
Optimized design with 32 mm frame height
Easy to install, weighs just 18.8 kg

Notes on the Data
System Disconnection for Cabling Works
All arrays at the Solar Centre were disconnected from approximately 2.00pm to 3.00pm on Monday, 9 July 2018 in preparation for the cable between the main switchboard and distribution board being upgraded. Array sites #23-38 remained disconnected while the main feeder cable to these sites was replaced in subsequent days, but all systems were re-connected by early afternoon on Thursday, 12 July 2018.
System Outage at Australia Day Long Weekend
A breaker tripped at around 12.30pm on Friday, 26 January, likely due to high generation levels reached at this peak time on this high irradiance day. Connection was restored after the Australia Day long weekend at around 11.30am on Monday, 29 January but shortly tripped again.
UPDATE 26-02-2018. The cause of this reoccurring issue has been identified and will be rectified. The solution requires the upgrading of a key distribution cable. This should be completed in the coming months.
Connection Restored After Christmas/NY Period
Arrays have been re-connected following the outage that disconnected multiple sites from Christmas day 2017. The outage is believed to have been triggered by the tripping of two circuit breakers in separate distribution boards, making the diagnosis initially elusive. The ability of the common circuit shared by these arrays to keep abreast with increasingly high current demands as new arrays are installed and generation conditions are high is presently being addressed. For the same reason, intermittent outages persisted in the summer of early 2018.
System Outage at Christmas/NY Period
A system outage was caused by a circuit breaker trip at approximately 2pm on a high generation day shortly after installation of a new array at the DKA Solar Centre. The outage commenced on 25 December continuing into the new year and is being addressed.
System Outage for New Array Connection
Sites 23 through to 37 experienced an outage today from 11:10 to 11:50. The outage was due to the local distribution board being temporarily being taken offline to allow for the connection of a new PV system.
Monitoring Interruption for UPS Battery Replacement
The disconnection and re-connection of the solar arrays and weather station equipment while a new site connection was being established prompted the already flattening UPS batteries which power the site’s energy meters to fail and require immediate replacement. Data recording was affected from approximately 2.30pm ACST, Monday 10 July to 4.00pm, Wednesday 12 July.
Affects weather data for DKASC, Alice Springs
Partial System Outage
One of the major switchboards at the DKASC lost power yesterday 01/12/2016 at ~11:00 am. This isolated and shutdown array sites 23 through to 37 inclusive. The switchboard was re-energised at ~16:30 today (02/12/2016) and is again operating normally. Data for this period for these sites is lost.
Sites 24 and 27: Temporary Outage
Both Site 24 and 27 went offline from the 14th to the 17th November 2016. This outage was caused by a contractor working on another system turning off these two systems for safety reasons and then forgetting to turn them back on after the work was complete. This outage was not a fault of the technology itself but rather simple human error.
Sites 24 and 25: Q-Cells PV Module Changeover Complete
Sites 24 and 25 are operational again from ~10th August 2016. At Q-Cells’ request, the original PV modules were removed and they have now been replaced with a more recent generation of PV product. Please visit the site for details.
Data from the two original arrays will be archived but remain available from the Historical Data Download page.

Q: What other parts and features would you consider if designing a solar cell to absorb maximum sunlight?
A: A solar cell's ability to absorb sunlight is influenced by its chemistry (type of material), colour (darker cells absorb more light), texture or surface treatments such as anti-reflective coatings, total exposure area (including any obstructions atop the cell's surface) and crystal constitution, also known as microstructure (such as density of crystal boundaries, which is related to individual crystal sizes). Product developers may also consider ways to extract maximum power from the received sunlight by optimising capture of different wavelengths or performance in a range of light conditions.
