BP Solar Panels come last in 2010 German Solar Panel Test


A recent solar panel test by German outfit “The TEC Institute for Technical Innovations” which put 15 Solar Panels under identical conditions for a month had some surprising results.

The test measured the power output of the following brands of solar panels:

  • CSI CS 5A 180 M
  • ULICA 180 (34) D-UL 800
  • Jiangyin Jetion JT 175 (35)
  • ANTARIS AS M 175 AI 1
  • SolarGate SG 2200
  • Yunnan Tianda TD 175 M5
  • 180 Sharp NU-180 E1
  • aleo S16
  • asola 185W/48
  • CSI CS6P-230P
  • Kyocera KC 175 GHT-2
  • Sym. Energy SE-M231
  • bpSolar 3210 N

Here are the results:

Basically the lesser known (and cheaper) brands like Ulica and the funny sounding Jiangyin Jetion produced more power in the test than the better known and generally more expensive brands such as Sharp, Kyocera and BP Solar in over their 1 month under the German Sun.

Of course your panels have to keep producing power over 25 or more years and the test doesn’t help measure the longevity of the panels, but the results are pretty interesting nonetheless.

    You dont say weather they are all mono or poly as both work the same, Mono generaly used for higher voltages and poly for increased amperage. Also mono and poly suit different climatic conditions.

  2. Hi just wondering jinko are they any good?

    […] and most of the information I could find on both was positive. I was particularly happy with this post on the “SolarQuotes” […]
