It has been almost seven months since I updated the data of my solar panel test results. Since we are about to add a new line-up of solar panels, it thought it was time to update the test results. We’ve had a fairly hot January and February in 2016, so the panels temperature co-efficient is put under pressure. Although QCells was the latest to be added to the line-up, all panels have had six to 12 months for their initial degradation period, and results should be close enough to make a fair comparison.
The screen shot below is updated regularly for transparency.
This screen shot was taken on the 18/6/16, from 1 weeks worth of data. The results below have not yet been updated. To get a comparisons to a 250W panel, divide the KWH of the panel by the watts of the panel (eg 265W for the Q cells). Then multiply the figure by the watts of the panel that you want to compare (EG 250 for the Jinko)
Panels – in order of cost
- LG 300W mono – tier 1 Q2 2015 Bloomberg
- QCells265w poly – tier 1 Q2 2015 Bloomberg
- Trina 250W poly – tier 1 Q2 2015 Bloomberg
- Rene 250W poly – tier 1 Q2 2015 Bloomberg
- Jinko 250W poly – tier 1 Q2 2015 Bloomberg, PQ panel
- Risen 250W poly – tier 1 Q2 2015 Bloomberg, PQ panel
- ZN Shine poly – tier 1 Q2 2015 Bloomberg
- BlueSun 250w poly

PQ panel refers to the Australian Solar Council’s Positive Quality programme.
Solar Panel Test Results – in order of performance
(results are as production PER WATT.)
- LG 300W – 102.7 percent
- Risen 250W – 100.2 percent
- Jinko 250W – 100 percent
- QCells 265W – 99.5 percent (slightly newer panel than the rest)

This solar panel test was made on a single panel purchased with no information of the testing intent.

My take on the solar panel test results
LG perform a bit better on the solar panel test. You will pay a lot more for that, but if you have a limited roof space, it makes sense.
Risen, Jinko, QCells, Rene and ZN shine are equivalent. Half a percent here or there on my test is negligible. The fact that Risen and Jinko are both PQ panels and come second and third for performance was interesting.
Trina concerns me, as it does in Photon testing.
Blue Sun and APS speak for themselves.
